Head lice or nits: how to spot them and tell if you have them

Head lice or nits? It’s not always easy to tell! Many people confuse nits with dandruff or assume they don’t have head lice because they can’t see them moving. In this article, we explain how to tell the difference between the two and determine whether you really do have an infestation. With clear explanations and photos, you’ll be able to identify the situation without making a mistake, and we’ll also provide treatment advice.

Key information

➡️ A louse is a live insect that moves around in the hair, whereas a nit is an egg attached to a hair shaft.
➡️Nits are immobile and very difficult to remove, unlike dandruff.
➡️Lice are mainly found behind the ears, at the nape of the neck and close to the scalp.
➡️Itching is common, but an infestation can be present without any symptoms.
➡️The most reliable way to check for lice is to use a lice comb on wet hair.

Head lice or nits: what’s the difference?

A louse is a living insect, whereas a nit is an egg.

There is a lot of confusion, particularly with dandruff or hair residue.

The louse (living insect)

The head louse, also known as Pediculus humanus capitis, is a small parasitic insect that lives on the scalp and feeds on blood. This condition is also referred to as “scalp pediculosis”.

Size: between 2 and 4 mm (roughly the size of a sesame seed)
Colour: greyish, brown or sometimes translucent depending on the light and hair colour
Appearance: elongated body, with 6 small legs that allow it to cling to the hair
Mobility: it moves quickly, making it difficult to see and catch
Behaviour: it moves along the hair shaft and often hides close to the scalp

Remember: if you see a small insect moving through your hair, it is definitely a louse… not a nits.

The nit (egg)

The nit is the louse’s egg. It is often the first thing to be spotted during an infestation.

Size: very small, approximately 0.5 to 1 mm
Colour: white, translucent or beige depending on its stage
Appearance: oval shape, slightly elongated
Position: firmly attached to the hair, close to the scalp
Mobility: it does not move at all

Unlike dandruff, a nit is difficult to remove. It remains attachedchée même si vous secouez les cheveux.

Good to know: a nits near the root is usually alive, whereas a nits further away from the scalp may be empty (after hatching).

Photos of lice and nits in the hair

Where should you look for lice in the hair?

To find out if you have lice, start by checking these areas:

behind the ears: a very common area for infestation
the nape of the neck: lice hide there easily
the hair roots: where the nits are attached
the scalp: close to the skin, where the lice feed

These areas should be checked first, as this is where lice attach themselves and lay their eggs.

To detect lice effectively, you need to use the right method:

wet the hair
apply conditioner to make detangling easier
use a lice comb
work under good lighting, using a magnifying glass if possible

Then:

Separate the hair into small sections
Run the comb from the roots to the tips
Check the comb after each pass

👉 This method is the most reliable way to detect lice, even when they are hard to see or the hair is long.

How can you tell if you have head lice?

Lice are not always easy to spot at the start of an infestation. Many people only realise they have them after several days, when the itching becomes more severe.

The most common sign: itching

The main symptom is an itchy scalp. This is caused by the bites of the lice as they feed on blood.

This itching mainly occurs:

behind the ears
at the nape of the neck
sometimes on the top of the head

It is often worse in the evening or after several days of infestation.

Other possible signs

As well as itching, you may notice:

small red patches or irritation on the skin
scratch marks
a feeling of discomfort in the hair
nits clinging near the roots

In some cases, repeated scratching can cause more severe skin irritation.

Can you have lice without itching?

Yes, especially at the beginning. Some people, particularly children, can have lice without scratching.

Can you have nits without lice?

Yes, it is entirely possible to find nits without any visible lice in the hair. This is quite common.

This may be due to:

A previous infestation: the lice have been eliminated, but some nits remain attached to the hair
Unhatched eggs: the nits are still present and may hatch into new lice in the coming days

What should you do in this case?

use a lice comb to remove as many nits as possible
monitor the hair for several days
check for any lice that may appear after the eggs hatch

Good to know: if the nits are located far from the root, they are often empty (old). However, if they are close to the scalp, they may still be active.

Can you have head lice without nits?

Yes, it is possible, especially at the start of an infestation. This usually means that the lice haven’t had time to lay eggs yet and that the reproductive cycle hasn’t begun.

Please note that the situation can change rapidly. An adult aphid can start laying eggs in just a few days.

What should you do in this case?

Check your hair regularly and use a lice comb to confirm whether there are any.

What do lice look like depending on hair colour?

The visibility of lice can vary depending on the colour and type of hair. Here is a table to help you understand:

Hair type	Visibility of lice	Explication
Blonde hair	More visible lice	Greyish or brown lice stand out more against light-coloured hair, making them easier to spot
Brown/dark hair	Less noticeable lice	Their colour is similar to that of hair, so they are less likely to be noticed
Thick or long hair	More difficult to detect	Lice can easily hide in thick hair, which makes checking for them a time-consuming and tedious process

What should you do if you have head lice?

Always start by:

confirming the infestation with a lice comb
checking the hair of those close to you (family, children)

Next, carry out a comprehensive lice treatment: anti-lice product + combing + repeat the process.

For children in childcare settings, there are also preventative measures available to reduce the risk of infestation.

To find out the step-by-step procedure and the most effective solutions, you can read our guide: How to get rid of head lice?

FAQ

How can you tell if a snail is dead?

A dead nit is usually further away from the scalp and often appears white or opaque. It is empty after hatching, unlike live nits, which are close to the root and translucent.

What does a louse look like?

A head louse is a small parasitic insect visible to the naked eye. It measures between 2 and 4 mm and has an elongated body with six small legs. It moves quickly through the hair. A live louse is usually found close to the scalp, particularly behind the ears and at the nape of the neck.

How long do nits stay attached?

Nits can remain attached to the hair for several weeks, even after hatching. They do not fall out on their own and must be removed by hand.

Can you see lice with the naked eye?

Yes, lice are visible to the naked eye. They are small, greyish insects measuring 2 to 4 mm in length, but they move quickly, which can make them difficult to spot.

Can you see lice in clean hair?

Yes. Head lice have nothing to do with hygiene. They can be found on both clean and dirty hair.

How can I remove nits on my own?

To remove nits effectively:
– use a lice comb on wet hair
– apply conditioner to make combing easier
– work through the hair strand by strand
It is a meticulous and sometimes tedious process, but essential for removing nits.

Tick bites in humans: risks, treatment and prevention

Although ticks primarily target animals, they can also feed on human blood and sometimes transmit diseases such as Lyme disease. If you are bitten by this parasitic insect, it is important to take the right action quickly. Don’t panic – here are the steps to follow and our advice on how to treat the bite.

N.B.: this article is not a substitute for the advice of a healthcare professional, which should always be sought first.

Key information

➡️ Ticks that affect humans are parasitic mites that feed on blood and can remain attached to the skin for several days.
➡️ Most tick bites are harmless, but some can transmit diseases such as Lyme disease, which is caused by bacteria.
➡️ It is important to remove the tick quickly using a tick remover, without using alcohol or pulling it out abruptly with your fingers.
➡️ After a bite, watch out for any unusual redness, tiredness or fever, and consult a healthcare professional if necessary.
➡️ To avoid bites, wear long-sleeved clothing, use a suitable repellent and check your skin after walking in high-risk areas.

Tick bites in humans

A human tick bite looks like a small dark lump attached to the skin. Its size varies depending on its stage of development and the amount of blood it has ingested.

Before feeding, the tick is very small (only a few millimetres). After feeding, it gradually swells and can grow to the size of a pea.

The parts of the body most commonly affected are:

the head and scalp
the neck
the armpits
the backs of the knees
the legs
the back
around the waist or skin folds

👉 Ticks prefer these areas because the skin is thinner or warmer there. This makes it easier for them to bite.

How does a tick bite a human?

A tick bite is generally painless, as the tick injects an anaesthetic substance when it bites. Most of the time, you won’t notice a thing.

Once attached:

the tick inserts its head into the skin
it attaches itself firmly using its mouthparts
it slowly feeds on the human’s blood

👉 Le repas sanguin peut durer de 24 heures à plusieurs jours. Pendant ce temps, la tique grossit progressivement.

After the bite, a skin reaction may occur:

a small red patch around the bite site
mild swelling
occasionally itching
more rarely, a more severe reaction depending on the individual’s sensitivity

See also: Ticks in dogs and cats.

Tick bites in babies

Finding a tick on a baby can be particularly worrying for parents, but don’t worry – the situation is usually harmless if the tick is removed quickly. As with adults, the tick attaches itself to the skin to feed on blood, but as babies’ skin is thinner and more sensitive, the bite can sometimes cause a more noticeable skin reaction.

In infants and young children, ticks often attach themselves to warm, hard-to-see areas:

the scalp
behind the ears
the neck
skin folds
under the arms
the backs of the knees

A small red patch may appear after removal, which is normal in most cases.

To protect your baby’s health:

remove the tick as soon as possible using a suitable tick remover
disinfect the area with a mild antiseptic
watch out for any spreading redness or a fever in the following days
consult a healthcare professional if in doubt

As a preventive measure, you can dress your child in long-sleeved and long-legged clothing when walking in high-risk areas and check their skin carefully after every outing.

The different colours of ticks

A tick’s colour depends mainly on:

its species
its stage of development (larva, nymph, adult)
whether it is engorged with blood or not

Black or dark brown tick

This is the most common colour. Many ticks are brown to black when they have not yet fed.

Example: Ixodes ricinus, the main tick vector for Lyme disease in Europe.

Red or reddish-brown tick

Some ticks have a reddish-brown hue, particularly in certain adult species. This colouration may also appear when the tick begins to feed on blood.

Light grey or whitish tick (engorged tick)

After feeding, the tick swells and may turn light grey, beige or whitish.

It may then resemble a small, soft lump attached to the skin.

Green tick: rare

Truly green ticks are very rare in Europe. Some tropical species may have a greenish sheen, but this is uncommon in temperate zones.

Areas and times of risk

Ticks are mainly found in:

forests and wooded areas
neglected gardens
wetlands
parks and hiking trails
certain so-called endemic regions in Europe, Africa or the Americas

They usually position themselves at the tips of plants and latch on when a human or animal passes by. You can therefore pick them up whilst out walking, hiking, picnicking or engaging in other outdoor activities air.

Good to know: the risk is higher if you live near a natural area or one frequented by wild animals.

Ticks can bite all year round, especially when the weather is mild. However, they are most active from spring to autumn, and between April and September.

Risks and diseases transmitted by ticks in humans

A tick bite in humans is usually harmless, but in some cases it can transmit pathogens that cause disease. These insects can indeed carry bacteria, viruses or parasites.

Lyme disease

Lyme disease is the best-known tick-borne illness in humans. It is caused by a bacterium called Borrelia burgdorferi. After a bite, the bacterium can enter the body and cause various symptoms, which usually appear a few days to a few weeks later.

The main sign is the appearance of a ring-shaped red rash around the bite site, known as erythema migrans. This rash may gradually spread around the bite.

Other possible symptoms include:

unusual tiredness
mild fever
headaches
muscle or joint pain
a general feeling of being unwell

How long does it take for Lyme disease to be transmitted?

The transmission of Lyme disease following a tick bite is not immediate.

The bacterium responsible for the disease is usually transmitted when the tick remains attached long enough to feed on blood.

👉 The risk of transmission increases significantly after 24 to 48 hours of the tick being attached.

In many cases:

before 24 hours, the risk of transmission is considered low
between 24 and 48 hours, the risk increases gradually
after 48 hours, the likelihood of transmission becomes higher

Good to know: The percentage of infected ticks in France varies from 0 to 20% depending on the region and the season (source: INRAE).

Possible complications

Without medical treatment, the progression of the disease can lead to complications affecting:

the joints
the nervous system
more rarely, the heart

👉 Early medical diagnosis enables effective management through appropriate antibiotic treatment.

Key point: Lyme disease remains relatively rare, and not all tick bites transmit the bacteria. However, it is still essential to monitor the bite site.

Should antibiotics be given?

Taking antibiotics after a tick bite is not routine. In most cases, it is not necessary, as not all ticks carry the bacteria responsible for diseases such as Lyme disease.

A course of antibiotics may be prescribed by a doctor when:

a migratory erythema appears (a circular redness spreading around the bite)
symptoms suggestive of Lyme disease develop (fever, unusual fatigue, joint pain, etc.)
the healthcare professional considers the risk to be high (endemic area, tick that has remained attached for a long time)

Other possible diseases

Illness	Possible symptoms	Risk level
Tick-borne encephalitis	Fever, fatigue, headaches, and neurological symptoms in severe cases.	Rare in France, but more common in Central and Eastern Europe.
Chickenpox	Fever, rash, tiredness, headache.	Found in certain warm regions, particularly in the Mediterranean region.
Other bacterial infections	Symptoms may vary: fever, muscle pain, fatigue, skin rash.	The risk varies depending on the region and exposure.

How do you remove a tick from a person?

The tick should be removed as soon as possible.

The safest method is to use a tick remover, a small tool available from pharmacies. This allows you to remove the tick without squeezing its body. This minimises the risk of transmitting pathogens.

Here’s how to do it:

Place the tick remover as close to the skin as possible, around the tick’s head.
Gently twist without pulling sharply until the tick comes away.
Check that the tick’s head has been removed completely.
Disinfect the area with a suitable antiseptic to prevent skin infection.
Wash your hands thoroughly after removal.

Avoid removing the tick with your fingers, as this can squeeze the tick’s abdomen and increase the risk of bacterial transmission.

What not to do

Do not:

apply alcohol or ether to the tick
use a chemical or an irritant
burn the tick with a heat source
pull it out abruptly with your fingers or standard tweezers

What should you do after a tick bite?

After removing the tick, you should keep an eye on the area for several days.

Here are the steps to follow:

monitor how the skin around the bite develops
note the date of the bite so you can track any symptoms
check for any unusual redness

What should I do if I don’t have tick tweezers?

If you don’t have tick tweezers, you can use fine tweezers or a piece of thread as a temporary solution.

Place the tick remover as close to the skin as possible, at the tick’s head, then pull gently and steadily without crushing its body. Once the tick has been removed, disinfect the area with an antiseptic. Avoid using alcohol, oil, chemicals or burning the tick, as this can increase the risk of bacterial transmission.

When should you see a doctor?

It is recommended that you consult a healthcare professional if you notice:

the appearance of erythema migrans, i.e. a circular redness that gradually spreads around the bite
a fever a few days or weeks after the bite
unusual tiredness
joint or muscle pain
a severe skin reaction (swelling, widespread redness, persistent irritation)
an abnormal development of the bite (unusual pain, significant inflammation, persistent symptoms)
concern that the tick’s head may have remained in the skin after removal

These signs may sometimes indicate a tick-borne infection, such as Lyme disease. A medical diagnosis then allows appropriate treatment to be put in place if necessary.

How can people avoid tick bites?

Here are some simple steps to protect yourself from tick bites:

Situation	Best practice
When out for a walk or a hike	Wear clothing that covers the skin (long trousers, long sleeves), opt for light-coloured clothing, and check your body after going outside
Skin protection	Use a suitable insect repellent, wear long clothing, and check children’s skin after outdoor activities
Take care after a hike	Check the head, neck, armpits, the backs of the knees and around the waist
Minimising environmental risks	Avoid walking through tall grass, stay on the paths, and avoid lying directly on the grass
Garden and pet care	Mow the lawn regularly, tend to the garden, check pets (dogs, cats) for ticks

FAQ

Where do ticks attach themselves on humans?

Ticks on humans usually attach themselves to areas of the body where the skin is thin and warm:
– on the head and scalp
– behind the ears
– on the neck
– under the arms
– behind the knees
– in the groin or around the waist
– on the back

How long does a tick stay attached to a person?

A tick can remain attached to the skin for anywhere from 24 hours to several days. During this time, it feeds on the human’s blood and gradually swells.

Is it okay to leave a tick’s head in?

No, it is best to remove the tick completely, including the head.
If the tick’s head remains in the skin, this can cause local inflammation, a minor skin infection or a persistent spot. In most cases, the body eventually eliminates this small fragment naturally, but it is advisable to disinfect the area and monitor the situation. If significant redness, pain or swelling develops, it is best to consult a healthcare professional.

How can you tell if you’ve been bitten by a tick?

In most cases, a tick bite does not lead to infection. However, certain symptoms may appear in the days or weeks following the bite:
– unusual redness around the bite
– unusual tiredness
– fever
– muscle or joint pain
– general malaise
If you notice any of these symptoms, consult a healthcare professional.

What is the first symptom of Lyme disease?

The first and most characteristic sign of Lyme disease is the appearance of a circular redness around the bite site. This red patch gradually spreads and may form a ring.
This is known as erythema migrans.

Does a shower get rid of ticks?

No, a shower just makes them easier to see. Ticks cling firmly to the skin using their mouthparts. If you find one, remove it with a tick remover.

Following the success of its solutions for bed bugs, SERENI-D now offers solutions for ALL household pests

Since its launch in 2021, Sereni-d® has established itself as an expert in bed bug control, offering effective, natural solutions that are accessible to both private individuals and professionals. Building on this experience, we have expanded our range to cover the main household pests: ants, moths, silverfish, fleas, mosquitoes and ticks.

The origins of Sereni-d: real-life experiences with bed bugs

The idea for Sereni-d® products arose from several memorable experiences: GR20 mountain huts in Corsica with bed bug infestations, followed by a stay in an Airbnb rental in Montreal. At the time, the conclusion was clear: there were no solutions that were effective, quick and natural all at once for combating bed bugs.

Aside from the bites, an infestation often causes significant stress and a real sense of helplessness. Faced with this gap in the market, Marine Falconnet, an engineer and mother of two, decided in 2021 to develop practical, effective and safe solutions capable of providing long-term help to individuals and professionals dealing with these pests.

👉 Today, more than 250,000 families have already regained a peaceful home environment thanks to Sereni-d® solutions.

Bed bugs: a public health issue

Bed bugs have become a genuine public health problem. More than a million people were affected in 2020 in Switzerland and France, and one in ten households was affected between 2017 and 2022 (source: Le Monde).

They are particularly prevalent in high-traffic areas such as hotels, short-term rentals, transport, shelters or public-facing establishments. In certain major cities such as Geneva, Paris or Marseille, entire blocks of flats can be affected.

In this context, Sereni-d® has committed to researching solutions based on plant-derived active ingredients, utilising more than fifteen plants to develop formulations that are both effective and sustainable.

New solutions for everyday pests

Drawing on its expertise, Sereni-d® now offers solutions to help tackle other common household pests. A new ‘Other Pests’ category has been created to provide practical solutions to the problems encountered in the home on a daily basis.

Ants

Ants can quickly swarm a kitchen or patio when they find a source of sugary food. An infestation can become persistent because these insects communicate with one another via pheromones, which attract the entire colony.

Serenid Mint Diatomaceous Earth for Ants · €26.90

A natural spray made from diatomaceous earth and mint to eliminate and prevent the appearance of ants.

👉Diatomaceous earth combined with peppermint essential oil works by mechanically dehydrating insects whilst creating a long-lasting repellent barrier.

Silverfish

Silverfish thrive in damp environments such as bathrooms, kitchens and cupboards. They can damage paper, fabrics and certain foods.

Stop Silverfish · €16.99

A targeted solution to reduce the presence of silverfish in damp areas of the home.

👉Appropriate treatment can quickly reduce their numbers and protect sensitive areas of the home.

Food moths

Food moths can infest foodstuffs such as flour, pasta or cereals. They lay their eggs in dry food, leading to a rapid infestation of the cupboard.

Food and fabric moth spray · €10.99

Ready-to-use spray to eliminate moths and larvae in food cupboards.

👉Our solution targets the larvae directly and helps to prevent them from spreading in the kitchen.

Clothes moths

Clothes moths feed on natural fibres such as wool, cotton and silk. They can damage clothes, carpets and fabrics stored in wardrobes.

Clothes moth repellent diffuser · €7.80

Long-lasting repellent diffuser to protect clothes and textiles.

👉The diffuser acts as a preventative measure by creating a long-lasting repellent barrier inside cupboards.

Products that are kind to both health and the environment

How can you get rid of mosquito larvae?

Female mosquitoes lay their eggs in stagnant water. Larvae then develop before becoming adults. To prevent them from multiplying around your home, you need to take action in good time. Here’s how to spot these larvae and the most effective ways to get rid of them.

The aim: to enjoy your garden, your swimming pool and your home without getting bitten.

Key information

➡️ A mosquito larva looks like a tadpole and can only survive in water.
➡️ The mosquito life cycle consists of four stages: eggs, larvae, pupae and adult insects.
➡️ In summer, a larva can develop into a mosquito in just one week.
➡️ Use a chlorine shock treatment to eliminate mosquito larvae in a swimming pool.
➡️ Removing standing water is the most effective way to prevent mosquitoes

The life cycle of mosquitoes

Mosquitoes go through four stages of development, taking between one and two weeks for the insect to reach adulthood.

1) Mosquito eggs

After feeding on blood, the female mosquito lays her eggs quickly, usually within 48 hours of feeding. The eggs are very small, measuring less than 1 mm.

Good to know: A female mosquito is fertilised only once in her lifetime, but can lay up to 1,000 eggs in just two months. An infestation can therefore spread very quickly.

Where are the eggs laid?

The laying site depends on the species of mosquito.

The tiger mosquito prefers very small areas of stagnant water such as saucers under flower pots, swimming pool covers, etc.

The common mosquito (Culex pipiens) lays its eggs directly on the surface of the water, often grouped together in small floating rafts.

Good to know: tiger mosquito eggs can remain dormant for several years or months, waiting for the right conditions to develop.

2) Mosquito larvae

One to two days after the eggs are laid, they hatch.

The mosquitoes then enter the larval stage. These larvae live entirely in water and feed on microorganisms, organic particles and algae found in their environment.

They regularly rise to the surface to breathe using a small breathing tube.

There are 4 larval stages:

Stage 1: 2 to 5 mm
Stage 2: 4 to 8 mm
Stage 3: 6 to 10 mm
Stage 4: 10 to 12 mm

Larval development depends heavily on the ambient temperature.

Temperature	Development of mosquito larvae
Around 20 °C	Mosquito larvae develop very quickly and can turn into adult mosquitoes in just one week.
Around 15 °C	The larvae’s development slows down significantly. It takes them longer to develop into adult mosquitoes.
Below 15 °C	The larvae’s development is generally halted. They do not continue to develop whilst the temperature remains low.

Good to know: in summer, it takes about a week for the larvae to develop, compared with several months in winter.

3) Nymphs

After the larval stage, mosquitoes enter the nymph stage. This phase is a period of transformation during which the insect undergoes metamorphosis. In particular, the respiratory tube develops into a respiratory proboscis.

The nymph still lives in the water but no longer feeds. It remains mobile and can dive when disturbed.

This phase generally lasts between 1 and 2 days, depending on the temperature.

4) Adult mosquitoes

Once the transformation is complete, the adult mosquito sheds its skin, emerges from the water and takes flight.

It is at this point that the insect becomes capable of reproducing. The females will then seek a blood meal so they can lay new eggs and start the cycle again.

How do you kill mosquito larvae?

Removing standing water is the first step in getting rid of mosquito larvae. It is the most effective way to prevent mosquitoes from breeding.

In practice, you can:

empty plant saucers regularly
clean gutters and drains
cover rainwater collectors
turn over buckets, watering cans or any objects that can collect water
check tarpaulins, swimming pools or garden ponds

Here are some other solutions.

Natural solutions

If you’ve already spotted larvae in a water source, there are some natural methods that can help kill mosquito larvae naturally.

White vinegar

The acidity of white vinegar can disrupt the development of the larvae.

Some people, for example, use a mixture of water and white vinegar to kill mosquito larvae in small amounts of water.

⚠️ Warning: this is only a temporary solution and does not replace the removal of stagnant water or the use of professional products.

Fish that eat larvae

Some fish feed on mosquito larvae in the water, which helps to reduce their population naturally. This is a great solution for garden ponds, pools or fountains, where the water cannot be drained regularly.

Here are the species of larvivorous fish:

The mosquitofish (Gambusia affinis)

This small fish can eat several dozen a day.

The goldfish

Goldfish can also eat mosquito larvae found in garden ponds.

👉 See also: All the solutions to get rid of mosquitoes

Swimming pool water treatment

A well-maintained swimming pool prevents mosquitoes from breeding, as the water is circulating and treated.

Shock chlorination

If larvae appear in a swimming pool, one of the most effective solutions is to carry out a shock chlorination treatment. This involves temporarily increasing the chlorine concentration in the water in order to quickly eliminate microorganisms, including mosquito larvae.

The principle is simple:

add a large dose of chlorine to the water,
leave it to work for several hours,
then restart the filtration system.

Shock chlorination generally destroys mosquito larvae in the swimming pool quickly.

Pool maintenance

To prevent larvae from reappearing, regular pool maintenance is essential.

Here are the best practices:

run the filtration system every day to prevent stagnant water,
regularly check the chlorine level and the water’s pH,
remove leaves and organic debris,
clean the walls and bottom of the pool,
use a tightly stretched tarpaulin or cover to prevent the accumulation of stagnant water.

How can you tell a mosquito larva apart?

A mosquito larva resembles a tadpole. It is a small, elongated organism that usually floats just below the surface. It is on average between a few millimetres and 1 cm long, depending on its stage of development.

A mosquito larva can be recognised by several characteristics:

shape: a small, slender, segmented body, resembling a tiny worm;
colour: usually greyish, light brown or translucent;
a clearly visible head, often darker than the rest of the body;
the rear end pointing towards the surface to breathe.

The larvae live exclusively in stagnant water: buckets, plant saucers, rainwater collection tanks or, occasionally, in a swimming pool if it is not properly maintained.

A very characteristic movement

When disturbed or when a shadow passes over the water, the larvae make a rapid zigzag movement.

They dive briefly towards the bottom and then rise to the surface to breathe. This jerky movement is typical and makes it easy to distinguish mosquito larvae from other small aquatic organisms.

How long does a mosquito live?

On average, an adult mosquito lives between two weeks and two months.

Male mosquitoes generally live between 5 and 10 days. They do not bite and feed solely on nectar and sugars found in plants.
Female mosquitoes, which are responsible for bites, live much longer. Their lifespan can reach 2 months, or even longer when conditions are favourable.

During this period, the female mosquito can complete several egg-laying cycles. After each blood meal, she can lay a new batch of eggs in stagnant water. In total, a female can produce up to 1,000 eggs in a few weeks, which explains why a small pondsence de moustiques peut rapidement se transformer en infestation.

Where can you find mosquito larvae in your home?

Mosquito larvae in stagnant water

The larvae mainly develop in stagnant water found around the house.

They can be found in the garden, on the patio or in various outdoor items containing water:

gutters
plant saucers
rainwater collectors
buckets

Mosquito larvae in the swimming pool

There may be mosquito larvae in your swimming pool if it is poorly maintained, if the filtration system is not working properly, or if the water becomes stagnant.

Tiger mosquito larvae

Tiger mosquito larvae are unique in that they can develop in very small amounts of water. A simple saucer, a drop of rainwater, a bottle cap or a small container can be enough for them to develop.

How can you prevent mosquito larvae from appearing?

Maintain your garden

Mosquitoes love poorly maintained gardens. The more vegetation there is, the more hiding places and potential breeding sites they have. So remember to mow your lawn, trim your shrubs and plants, and above all, avoid letting things pile up.

Monitor water sources

Mosquitoes can lay their eggs in very small amounts of water.

Be particularly vigilant about:

rainwater collectors,
garden ponds,
fountains,
poorly maintained swimming pools

Prevention against tiger mosquitoes

Tiger mosquito larvae have the distinctive feature of developing in very small volumes of water.

To limit their proliferation:

eliminate all small areas of stagnant water,
regularly check items on your balcony or terrace,
keep an eye on tarpaulins, gutters and rainwater collectors.

FAQ

How long do mosquito larvae live?

The lifespan of the larvae depends mainly on the water temperature. On average, the larval stage lasts about one week.
When the temperature exceeds 20 °C, the larvae develop very quickly and can become adult mosquitoes in just one week. At lower temperatures, their development is slower.

What does a mosquito larva eat?

Mosquito larvae feed mainly on microorganisms found in water:
– microscopic algae
– bacteria
– decomposing organic matter
– small particles found in stagnant water
This is why water rich in organic matter encourages their development.

Can mosquito larvae be found in a swimming pool?

Yes, if the swimming pool is not properly maintained.
Mosquitoes can lay their eggs in a swimming pool if:
– the water remains stagnant for several days,
– the filtration system is not working properly,
– the chlorine level is too low.

Can mosquito larvae survive out of water?

No, mosquito larvae cannot survive out of water. They live exclusively in an aquatic environment throughout their entire development.
A mosquito larva in the water breathes through a small breathing tube at the tip of its body. It must regularly rise to the surface to take in air. If it finds itself out of the water, it dries out quickly and dies within a short time.

How can I get rid of mosquitoes ?

Itchy bites, disturbed sleep, disease transmission – mosquitoes make everyday life a real nuisance. Unfortunately, the invasion of the tiger mosquito in France is only making matters worse. So, can we get rid of them? Here are the most effective ways to combat these insects.

Natural ways to get rid of mosquitoes

Before resorting to insecticides, there are several simple and natural ways to keep mosquitoes at bay.

Mosquito-repelling plants

Certain types of plants give off scents that mosquitoes find unpleasant. Feel free to place them on your balcony, terrace or near windows.

Lemongrass

Lemongrass is one of the best-known plants for repelling mosquitoes. Its lemony scent acts as a natural repellent. It is also found in many products such as candles and mosquito repellent sprays.

Lemongrass geranium

Lemongrass geranium, or Pelargonium citronellum, is an ornamental plant often used on patios and balconies. Its scent, which is similar to lemongrass, helps to keep mosquitoes at bay.

Lavender

This aromatic plant gives off a scent that is pleasant to humans but unpleasant to mosquitoes. Do make the most of it!

Mint

Mint also has a strong scent that can help keep mosquitoes away from certain areas of the garden or patio.

Good to know: using these mosquito-repelling plants on their own is not enough. They need to be combined with other solutions.

Essential oils that repel mosquitoes

The strong scent of essential oils acts as a repellent and keeps mosquitoes at bay.

Here are the most commonly used ones against these insects.

Essential oil	Mosquito-repellent properties
Lemongrass	Lemongrass essential oil has a lemony scent that acts as a natural repellent.
True lavender	True lavender essential oil can help keep mosquitoes at bay whilst leaving a pleasant scent in the home.
Lemon eucalyptus	Widely used in insect repellent sprays, lemon eucalyptus essential oil is considered one of the most effective at keeping mosquitoes at bay.
Rose geranium	The essential oil derived from mosquito-repellent geranium also has some interesting repellent properties.

How can essential oils be used to repel mosquitoes?

You can use essential oils in various ways:

in a mosquito repellent diffuser inside your home,
diluted in water to make a repellent spray,
applied to a carrier (fabric, pebble, cotton wool) placed near windows or on the patio.

⚠️ Warning: essential oils must always be used with caution. Some are not recommended for young children, pregnant women or pets. They must never be applied undiluted to the skin.

Bats versus mosquitoes

A bat can eat up to 3,000 mosquitoes a night. They are therefore valuable allies in controlling the mosquito population. However, contrary to popular belief, mosquitoes are not their main source of food. They often prefer larger, more nutritious insects.

To attract bats to your garden or around your home, install bat boxes on a wall or in a tree, in a quiet spot sheltered from the wind.

Good to know: some local councils provide bird boxes. Feel free to contact yours.

Mosquito traps

Unlike repellents, which keep insects away, mosquito traps are designed to attract, capture and kill them. Here are the different types available.

CO₂ traps

Some traps mimic human breathing by releasing carbon dioxide (CO₂). As we saw earlier, this is one of the main factors that attract mosquitoes.

The way it works is simple:

the trap releases CO₂ to attract mosquitoes,
the insects approach, thinking they have found a host,
and a suction system captures them.

This type of trap is often used in gardens or areas with severe infestations. It is effective at reducing the mosquito population over a fairly large area.

Light traps

Some devices attract insects using UV light.

Once attracted, the mosquitoes are:

sucked into a compartment,
or killed by electrocution on an electric grid.

⚠️ Warning: these traps attract many flying insects and do not target mosquitoes exclusively.

Stagnant water traps (egg-laying traps)

Another method involves using a trap that attracts female mosquitoes when they are ready to lay eggs. The device contains water and sometimes a specific attractant.

Mosquitoes lay their eggs in it, but the larvae cannot develop or escape from the trap. This type of trap directly targets the reproduction of these insects.

Homemade traps

There are also simple traps that you can make yourself.

For example:

a cut-off bottle containing a mixture of water, sugar and yeast,
a dark container with a little stagnant water covered with cling film to prevent the insects from escaping.

These solutions can catch a few mosquitoes, but their effectiveness is limited when the infestation is severe.

Effective traps for tiger mosquitoes

There are traps specifically designed for tiger mosquitoes. These devices differ from conventional traps as they target the specific behaviour of the tiger mosquito (Aedes albopictus), which bites mainly during the day and lays its eggs in small areas of stagnant water.

The best known are egg-laying traps, also known as ovitraps. The principle is simple: they mimic an ideal place to lay eggs. The trap contains a small amount of water and a dark surface that attracts female mosquitoes. Tiger mosquitoes come to lay their eggs there. The adults or larvae are then trapped and cannot develop.

Mosquito control accessories

The mosquito repellent plug

It’s often an essential accessory for our summer nights. The mosquito repellent plug, also known as a diffuser, plugs directly into a power socket and releases a repellent or insecticide into the air. The aim: to sleep soundly!

There are several types available:

models with impregnated pads, which need to be replaced regularly,
liquid diffusers, which can last for several weeks,
some devices combined with a fan or a gradual release mechanism.

The advantage of this solution is that it works continuously for several hours and can help reduce mosquito bites during the night.

⚠️ Please note: these products must be used with care. Remember to air the room regularly and avoid prolonged use in the baby’s bedroom.

The mosquito repellent bracelet

The mosquito repellent bracelet is often used outdoors (hiking, camping, gardening). It is worn on the wrist or ankle and releases a scent designed to repel mosquitoes.

Most mosquito repellent bracelets work by using repellent substances impregnated into the bracelet, often based on essential oils such as citronella, lavender or geraniol. The aim is to mask the human body’s scent so that mosquitoes can no longer detect their target.

However, their effectiveness remains very limited. Several tests and studies show that these bracelets only protect the area very close to the bracelet, and sometimes for just a few hours.

The mosquito swatter

The “mosquito swatter” is often used to kill mosquitoes at home. It looks like a miniature tennis racket fitted with an electric grid. When the insect comes into contact with the grid, it is immediately electrocuted.

It is handy, for example, for hunting down mosquitoes in your bedroom before going to sleep. The advantage is that it does not release any chemicals and can therefore be used indoors without any problems.

Mosquito-repelling lamps and floor lamps

These devices work by emitting UV light that attracts insects. Once they are close by, the mosquitoes are either:

electrocuted by an electric grid,
sucked into a compartment,
or trapped in a reservoir.

These devices can be useful for reducing the number of insects around an outdoor area, particularly on summer evenings.

However, there are two issues with these lamps:

they aren’t very effective. Mosquitoes aren’t particularly attracted to light. They mainly locate their victims through carbon dioxide, body heat and skin odours.
you also catch other insects

How can you get rid of mosquitoes at night?

Mosquitoes are particularly active in the evening and at night. They are attracted by body heat and the carbon dioxide we exhale whilst sleeping. The result: repeated mosquito bites that can disrupt your sleep.

Here are the most effective ways to keep mosquitoes at bay at night.

Fitting a mosquito net

A mosquito net remains one of the most effective ways to sleep without being bothered by mosquitoes. It physically prevents insects from reaching your skin.

You can fit:

a mosquito net on the windows
a mosquito net around the bed

Using a mosquito repellent diffuser

A mosquito plug-in or mosquito repellent diffuser keeps mosquitoes at bay for several hours.

A few tips:

plug in the diffuser 30 minutes before going to bed,
air the room before and after use.

Avoiding attracting mosquitoes at night

Here are a few simple steps to keep mosquitoes out of your bedroom:

avoid opening windows without mosquito nets when the light is on,
use mosquito repellent on your skin if necessary,
wear long pyjamas if there are a lot of mosquitoes.

How can I keep mosquitoes away?

As we have seen, these insects are attracted to moisture, body odours and the carbon dioxide we breathe out.

Here, then, are some effective ways to keep mosquitoes at bay:

Remove standing water around your home to prevent mosquito larvae from developing.
Install mosquito nets on windows or around the bed to avoid bites during the night.
Use a mosquito repellent on your skin or in your surroundings (diffuser, spray, citronella candle).
Plant mosquito-repelling plants on the balcony or terrace (lavender, citronella, geranium).
Wear covering clothing in the evening when mosquitoes are most active.

What attracts mosquitoes?

These insects are attracted by several factors linked to the environment and the human body.

Stagnant water: an ideal breeding ground for larvae

Mosquitoes need stagnant water to reproduce. The female mosquito lays her eggs there, which then develop into mosquito larvae and eventually into adult mosquitoes.

Mosquito larvae are often found in:

plant saucers,
rainwater collection tanks,
blocked gutters,
buckets or watering cans left outside,
poorly maintained swimming pools.

Just a few millimetres of water is enough for mosquito larvae to develop.

The carbon dioxide we breathe out

Mosquitoes track down their victims using the carbon dioxide (CO₂) we exhale when we breathe. The more CO₂ a person releases, the more likely they are to attract these insects.

This is particularly true of:

people who are exercising,
pregnant women,
or people who are breathing more rapidly.

This is also why mosquitoes buzz around your head at night.

Body heat and sweat

Body heat and certain odours produced by the skin also attract mosquitoes. Sweat releases chemicals that these insects can detect very easily. This is why some people feel they are bitten more often than others.

Good to know: drinking alcohol also attracts mosquitoes.

Blood type

Many of you feel you get bitten more than others. You’re not imagining things.

Several scientific studies suggest that blood type may influence how attractive you are to mosquitoes. A study published in 2004 in the Journal of Medical Entomology showed that mosquitoes are more attracted to people with blood group O than to those with groups A or B. Researchers observed that mosquitoes landed on individuals with group O almost twice as often.

Odours and the surroundings of your home

Finally, the area around your home also plays a role. Mosquitoes love:

damp areas,
gardens with lots of vegetation,
hedges and shaded areas,
patios where water can collect.

These places provide them with moisture, shade and hiding places during the day.

FAQ

How can you get rid of mosquitoes quickly?

To keep mosquitoes at bay quickly, you can use a mosquito repellent applied to the skin or in the surrounding area. Mosquito sprays, electric repellent devices or citronella candles can help reduce bites within minutes.

How can I get rid of a mosquito infestation?

If you have an infestation, you need to tackle the root cause of the problem. Mosquitoes breed in stagnant water, where their larvae develop.

Here is what you should do first:
– empty plant saucers and containers holding water,
– clean gutters and rainwater collectors,
– use a mosquito trap or a tiger mosquito trap in the garden,
– install mosquito nets and repellents in the house.

How can I get rid of mosquitoes inside the house?

To keep mosquitoes out of your home, there are several options available:
– fit mosquito nets to your windows,
– use a plug-in mosquito repellent or a mosquito diffuser,
– swat any insects you see with a fly swatter,
– check that there is no standing water in plant saucers.

How can you get rid of mosquitoes outdoors?

To get rid of mosquitoes outdoors, it is essential to eliminate their breeding grounds.

In particular, remember to:
– empty containers holding water regularly,
– maintain your gutters,
– cover rainwater collection tanks,
– plant mosquito-repelling plants such as lemongrass, lavender or citronella geranium.

How can you keep mosquitoes away using a traditional remedy?

Some old wives’ remedies can help keep mosquitoes at bay:
– place candles or essential oils containing citronella,
– use lavender or citronella geranium to repel mosquitoes,
– spray a mixture of water and white vinegar around high-traffic areas.

What is the smell that mosquitoes hate the most?

Mosquitoes are sensitive to certain strong smells. The scents that repel them most effectively include:
– lemongrass,
– lavender,
– lemon eucalyptus,
– lemon geranium,
– peppermint.

What you need to know about fleas: biology, behaviour and risks

Fleas are small insects that feed mainly on the blood of dogs and cats. Biological characteristics, behaviour, risks to humans, treatments: here is everything you need to know about fleas.

Objective: to understand them better in order to eliminate them more effectively.

Key information

➡️Fleas are ectoparasitic insects: they feed on the blood of their hosts.
➡️Their hosts are mainly dogs and cats.
➡️They can bite humans, although animals are their preferred hosts.
➡️Flea bites are generally not serious for humans, but they cause severe itching.
➡️ Fleas are present all year round, with seasonal peaks.
➡️A female flea can lay between 20 and 50 eggs per day.
➡️To get rid of them, both the animal and the home must be treated.

What is a flea: description and characteristics of the insect

The flea is a small parasitic insect belonging to the order Siphonaptera (from the Latin sipho, meaning “tube”). It is one of the so-called biting-sucking insects, as it feeds exclusively on blood, which it draws from its hosts (mainly dogs and cats, but sometimes also humans). They are therefore classified as blood-sucking insects, in the same way as mosquitoes.

What does a flea look like?

Fleas are small, wingless insects protected by a layer covered with spines (cuticle).

Size: approximately 3 to 8 mm.
Colour: reddish-brown to blackish.
Body: flattened laterally (on the sides), allowing it to easily slip between hairs or textile fibres.
Legs: highly developed at the rear, capable of propelling the flea several dozen centimetres to move from one host to another.

Their anatomy is designed to:

bite the skin,
suck blood,
move quickly from one host to another by jumping.

Difference from other biting insects

Fleas are often confused with other biting insects, but their behaviour is quite distinct:

Mosquito	flies, bites mainly at night, does not remain on the host permanently.
Bed bugs	does not jump, hides in furniture and only bites to feed at night.
Tick	clings to the skin for a long time and remains attached for several days to feed.

The flea jumps, bites quickly, then returns to its environment (pet basket, carpet, skirting boards, bedding).

For your information, there are three types of fleas:

Fur fleas, which live exclusively on their host
Nidicolic fleas, which live in their host’s shelter: pet basket, nest, burrow, etc.
Sedentary fleas, which remain attached to their host in the same place without moving

Photos of fleas

Life cycle of fleas: eggs, larvae, pupae and adults

1) Flea eggs

After each blood meal, the female flea begins to lay eggs rapidly. She can produce up to 50 eggs per day for 50 to 100 days. An infestation can therefore quickly take hold in a home.

Eggs hatch more easily when:

the temperature is mild to warm (20–30 °C),
the air is humid,
access to food is easy, for example with the presence of domestic animals in the home.

These eggs resemble tiny white grains of rice measuring 0.5 mm.

Where are the eggs laid?

The eggs do not remain attached to the animal. They are mainly found in the environment:

in the coat of dogs or cats (at the time of laying),
then quickly in the soil,
animal baskets and cushions,
rugs and carpets,
dust, cracks in parquet flooring and skirting boards.

Good to know: an interior can be infested even if few adult fleas are visible on the animal. The animal’s movements (walking, scratching, sleeping) are enough to scatter eggs throughout the house.

Flea larvae

After the eggs hatch (between 2 and 10 days), fleas go through a larval stage that lasts between 5 and 11 days. These larvae develop entirely in the environment (not on the animal).

What do flea larvae look like?

Small in size (approximately 1.5 mm),
whitish to translucent in colour,
shaped like a tiny worm,
without legs or wings.

What do they feed on?

Unlike adult fleas, larvae do not bite or suck blood directly. They feed mainly on organic debris (dead skin, dust), dried blood contained in the excrement of adult fleas, or residues found in textiles (carpets, pet baskets, cushions).

This link between adult fleas and larvae explains why an infestation is self-sustaining: the adults indirectly feed the larvae.

Where do the larvae hide?

Flea larvae take refuge in places that are:

dark,
quiet,
protected from traffic.

They are mainly found in:

cracks in the floor,
skirting boards,
carpets and rugs,
pet baskets and blankets,
gaps in wooden floors and dusty areas.

Nymphs

After the larval stage, the flea larva transforms into a nymph by enclosing itself in a protective cocoon made from dust, hair and other debris. This stage lasts a few weeks. During this period, the larva gradually takes on the shape of the adult insect with legs and antennae.

The cocoon protects the future adult flea from:

moderate cold,
dryness,
and even certain insecticides.

The flea can remain in this cocoon for several weeks or even months, waiting for a host.

The adult flea

It is at this stage that the flea becomes a biting-sucking parasite, capable of causing infestation in both animals and humans.

A vital need for blood

In order to survive and reproduce, adult fleas must feed on blood. They bite their host (dogs, cats, but sometimes also humans) using their specialised mouthparts, then suck blood for several minutes.

Without a blood meal, they cannot lay eggs and eventually die.

Although their preferred targets are domestic animals, fleas can also bite humans when:

the host animal is no longer available,
the infestation is severe,
or fleas are already present in the environment (carpets, bedding, sofas).

Life span of an adult flea

When conditions are favourable (heat, humidity, presence of a host), adult fleas can live for up to 3 to 4 months. Fleas can also live for several months without feeding by slowing down their metabolism.

The different species of fleas

Here are the most common species of fleas and their hosts.

The cat flea (Ctenocephalides felis)

The cat flea, or Ctenocephalides felis, accounts for the majority of infestations observed in private homes. It is found in both urban and rural areas, all year round when homes are heated.

Please note that this flea is not specific to cats. It also parasitises dogs and can bite humans if there are no animals present or in the event of a major infestation in the home.

Its bites are often clustered together, very pruritic (they itch intensely) and appear mainly on the legs and ankles in humans..

A particularly resistant flea

The cat flea is known for:

their high reproductive capacity (a female flea lays around 25 eggs per day and 1,000 to 2,000 during her lifetime),
their environmental resistance (eggs, larvae and cocoons survive for a long time in the home),
and their ability to quickly colonise carpets, pet baskets, sofas and cracks in the floor.

Good to know: even if your pet does not go outside much, cat fleas can enter your home via another animal, clothing or an already infested environment.

The dog flea (Ctenocephalides canis)

The dog flea is a species closely related to the cat flea, with which it is often confused. However, Ctenocephalides canis is less widespread. In most cases of infestation in dogs, it is actually Ctenocephalides felis, which is more resistant and better adapted to indoor environments.

In terms of morphology and behaviour, the dog flea is almost identical to the cat flea.

Fleas can transmit worms (Dipylidium caninum) to dogs and trigger allergies.

Other possible hosts

More rarely, there are fleas specific to certain wild animals, particularly rodents and small mammals:

squirrels,
martens,
certain marsupials (in other parts of the world),
rats and mice.

Risks and diseases associated with fleas

Most flea bites are harmless, but in some cases these insects can transmit diseases.

A historical reminder: the plague and the ‘plague flea’

Fleas are infamous for their role in the great plague epidemics of the Middle Ages.

The bacterium Yersinia pestis was transmitted to humans by fleas living on rodents under infestation (particularly rats).

These were known as plague fleas, capable of infecting humans after biting an animal carrying the bacterium. Today, such cases are exceptional in Europe, but this historical episode explains why fleas are classified as potential disease vectors.

Risks to animals

In dogs and cats, flea infestation can cause:

intense itching,
skin lesions caused by scratching (pruritus),
allergic dermatitis caused by flea saliva,
possible transmission of intestinal parasites (tapeworms),
anaemia in young animals in the event of a massive infestation.

Animals are therefore the primary victims of fleas, well ahead of humans.

Risks to humans

In humans, fleas can cause:

multiple bites, often on the legs, ankles or arms,
severe itching,
sometimes local allergic reactions,
in very rare cases, secondary infection if the skin is scratched too much.

The transmission of serious diseases to humans remains very rare, but is theoretically possible in the presence of rodents with infestations or in highly degraded environments.

Certain species of fleas can carry bacteria that cause:

prolonged fevers,
headaches,
intense fatigue,
skin rashes.

Flea bites

Fleas are biting-sucking insects: they pierce the skin to feed on blood.

What does a flea bite look like?

The bites are often clustered together, extremely itchy and located on the legs, ankles or arms.

On the skin, these bites take the form of small pink or red spots with a brighter dot in the centre.

Unlike a mosquito, which bites only once, fleas can bite several times in a row as they move around. Animals are the first victims of fleas, long before humans.

Itching and risks associated with scratching

Flea bites cause severe itching (caused by the insect’s saliva), sometimes accompanied by slight local swelling.

➡️ Tip: clean the bitten area with soap and water, apply a soothing or antiseptic cream, and avoid scratching to limit complications.

Some sensitive individuals may experience a local allergic reaction.

Consult your doctor if necessary.

Difference between flea, mosquito and bedbug bites

Insect	Appearance of the bite	Organisation of injections	Areas of the body most affected
Chip	Small red spots, sometimes with a central dot	In clusters or short rows	Legs, ankles, feet
Mosquito	Larger, round, and swollen button	Isolated	Arms, legs, face, exposed areas
Bed bugs	Red buttons in a row (1 to 5)	Online or in a regular group	Arms, back, neck, shoulders

Bed bugs or bed bugs?

People often mistakenly refer to bed bugs as “fleas in bed”. This is a linguistic error: there is no species called “bed flea”.

These are two very different insects, even though they both bite and live in the human environment.

Confusing fleas with bed bugs can lead to incorrect treatment:

for fleas, you need to treat the animal, floors and textiles,
for bed bugs, you need to target bedding, furniture and corners near the bed.

Flea treatments

Flea treatment must always be comprehensive, as simply eliminating the insects visibles ne suffit pas : les œufs, larves et cocons restent présents dans l’environnement et peuvent relancer une infestation.

Treat your pet (essential)

If you have a dog or cat, the first thing to do is to use a suitable flea treatment:

spot-on pipettes,
flea collars,
veterinary tablets.

Without treating your pet, the fleas will continue to feed and reproduce.

So remember to consultlter votre vétérinaire dès que possible.

Dealing with housing

Please note that during an infestation with fleas, 5% of the insects are found on the animal and 95% in the home.

You must therefore treat your home thoroughly:

Vacuum carpets, skirting boards, sofas, baskets and cracks thoroughly.
Wash textiles (cushions, blankets, baskets) at a high temperature.
If necessary, use specific insecticides, fumigants or flea traps to reduce the adult population.

FAQ

Can fleas live on humans?

No. Fleas may bite humans to feed, but they do not live on them permanently. They prefer animals (dogs, cats, rodents) whose fur provides them with warmth, protection and regular access to blood.

Do fleas jump on beds?

Yes. Fleas can jump onto a bed if it is close to an area affected by infestation (pet basket, carpet, skirting boards).
They do not live there permanently, but they can:
– bite during the night,
– fall off the body of an animal sleeping on the bed,
– hide in textiles (blankets, sheets).

Can an house with an infestation get rid of fleas on its own?

No. An infestation of fleas does not disappear spontaneously.
Without treatment:
– eggs continue to hatch,
– larvae develop in hidden corners,
– adults feed and reproduce.
– Action must be taken on both the animals (flea treatment) and the home (vacuuming, washing, targeted treatment).

Are flea bites dangerous?

Most of the time, they are not serious, but:
– they cause intense itching,
– they can become infected if scratched,
– some people develop more severe allergic reactions.

How to recognise an infestation of fleas?

Several signs may indicate an infestation:
– clusters of bites on the legs, ankles or folds of skin,
– visible fleas in an animal’s coat,
– small black dots (faeces) in baskets, rugs or cushions,
– animal scratching intensely,
– sensation of rapid, repeated bites in the home.

How to get rid of silverfish?

The silverfish, also known as the ‘silverfish,’ is a small insect measuring 10-15 mm with two long antennae that moves like a fish. It is often found in warm, dark corners of the home. Although harmless to humans, the presence of this small insect can be disturbing. It’s not very pleasant to see them swarming around your home! So how can you get rid of silverfish? Here are some natural solutions for effective treatment and prevention tips.

Natural methods for getting rid of silverfish

Here is a series of effective treatments against silverfish using products that are easy to find and safe for your health.

Baking soda

Easy to find, inexpensive and non-toxic to humans, baking soda is very useful for cleaning.

How does baking soda affect silverfish?

Specifically, it acts in two ways on silverfish:

By ingestion: attracted by organic residues, silverfish ingest the bicarbonate, which disrupts their digestive system and causes their death.
By desiccation: this powder absorbs moisture and gradually dries out the bodies of silverfish.

How to use bicarbonate of soda?

You can place it in areas where silverfish hide and circulate:

along skirting boards,
in dark corners,
under sinks and near pipes,
in storage rooms, cellars or laundry rooms,
behind furniture and at the back of cupboards.

➡️Tip: you can mix the bicarbonate of soda with a little sugar or flour to make the trap more attractive. Place the mixture in small bowls or directly on the floor.

Please note that bicarbonate of soda does not act on silverfish eggs or on the cause of the problem (damp, cracks). It must be combined with other measures (cleaning, reducing damp, prevention) to eradicate the infestation permanently.

White vinegar

White vinegar acts as a repellent against silverfish. Feel free to spray it in areas where insects are likely to pass through and/or clean your surfaces with it.

Diatomaceous earth

Diatomaceous earth is a mineral powder derived from fossilised microalgae, which is completely natural when used for food purposes (uncalcined). It is an effective treatment against many harmful insects such as silverfish and bed bugs.

How does diatomaceous earth work?

Upon contact, insects gradually dehydrate and die within a few days. Diatomaceous earth works equally well on adults and young specimens.

How can you use it effectively at home?

Sprinkle a thin layer of diatomaceous earth where silverfish tend to travel: along skirting boards, in cracks and crevices, under sinks and around pipes, etc. Avoid making visible piles; instead, try to create light barriers that the silverfish will cross.

Silverfish and bleach: avoid!

Be careful, this is a bad idea. Contrary to what you might think, bleach can actually attract silverfish. It leaves surfaces damp after rinsing (which these insects like), its smell disappears quickly and it is not a long-lasting repellent.

Traps for silverfish

Sticky traps

Sticky traps are simple and effective for capturing silverfish during their night-time movements. You can find them in shops.

How it works:

Silverfish travel along walls, skirting boards and pipes. When they cross the adhesive surface, they become trapped.

Homemade traps

Silverfish feed on materials rich in starch and cellulose.

Here are two trap ideas you can use at home.

Damp cardboard trap:

Take a piece of plain cardboard (without ink).
Dampen it slightly.
Roll it up and place it in a dark corner overnight.
In the morning, collect the cardboard filled with silverfish and throw it into a sealed bag.

Starch trap:

Sprinkle a little flour, cornflour or starch into a small container.
Place it near the infested areas.
Silverfish are attracted to it, gather there and can then be disposed of.

👉 By combining these traps with regular cleaning and reducing humidity, you greatly increase your chances of getting rid of silverfish for good.

When should chemical treatments be used?

In most cases, natural methods are sufficient to get rid of silverfish, especially when there are only a few. However, if the insects keep coming back after cleaning and there are too many of them, certain insecticide treatments in powder or gel form may be useful.

⚠️ Before use:

read the product instructions carefully,
ventilate the room well,
avoid applying to surfaces that come into contact with hands or food,
wear gloves and never mix several products.

How can you find silverfish nests?

Unlike other pests, silverfish do not build visible nests such as ant hills or swarms. However, they do gather in areas that are favourable to their development, where they feed, reproduce and lay their eggs.

Silverfish primarily seek:

moisture,
darkness,
calm,
and organic matter to consume (paper, glue, dust, food residues).

They avoid light and mainly come out at night.

What to do in the event of an infestation in a building?

When silverfish appear in an apartment, it is highly likely that the problem is not isolated. In a building, these silvery insects can easily move from one dwelling to another through pipes, service ducts, crawl spaces and cracks. This is often the case in old or very damp buildings (basements, ageing drainage systems). Rest assured, however, silverfish are not harmful to your health.

To find out if the infestation is widespread, do not hesitate to ask your neighbours.

Notify the property manager and your landlord

This is the first thing you should do. You can send an email to your property manager and landlord, specifying the areas affected by infestation (apartment, common areas). Include photos if possible.

Arrange for collective treatment

In a building, it is often necessary to call in a professional pest control company.

An exterminator will be able to:

propose a prevention plan to avoid re-infestation.
detect the infested areas,
apply targeted treatments in the common areas,
use appropriate and regulated products,

Who should pay for collective treatment against silverfish?

In principle, it is the co-owners’ association that should pay for treatment against silverfish. The property manager is responsible for ensuring the maintenance and cleanliness of the common areas.

Effective ways to prevent silverfish

Prevention is essential to stop silverfish from reappearing after treatment. Here is an effective checklist to limit the risk of infestation.

Reduce humidity

Ventilate each room for at least 10 to 15 minutes every day.
Use a dehumidifier in damp rooms (bathroom, cellar, laundry room).
Repair water leaks quickly (siphons, seals, pipes).

Clean regularly

Clean floors, skirting boards and under furniture with a household cleaner.
Vacuum corners, cracks and dark areas where silverfish like to hide.
Wipe up any standing water immediately.
Place all food in sealed, watertight containers.
Pick up any crumbs that have fallen on the floor or worktop.

Eliminate hiding places

FAQ

Where are the silver fish hiding?

Silverfish are discreet, nocturnal insects. They hide during the day in dark, quiet, damp places, then come out at night to feed.

They are most often found:
– behind skirting boards and under floors,
– in pipes, siphons and under sinks,
– at the bottom of rarely used furniture, drawers and cupboards,
– in bathrooms, toilets, cellars and laundry rooms,
– near washing machines, water heaters or poorly ventilated areas.

Why do I have silverfish in my home?

Silverfish are transported by humans via wooden, cardboard or paper objects.

Once they have entered a home, they proliferate if there is:
– high humidity (wet rooms, poor ventilation),
– water leaks or condensation,
– dark, uncleaned corners,
– the presence of materials they consume: paper, cardboard, dust, glue, food residues, mould,

They can also come from your neighbours’ homes via shared pipes or ducts.

Are silverfish dangerous to your health or your home?

No, silverfish are not dangerous to human health:
– they do not sting,
– they do not bite,
– they do not transmit any diseases.

However, they can be a nuisance in public buildings or homes:
– they can damage books, papers, cardboard, wallpaper,
– their repeated presence is often a sign of a damp problem that needs to be fixed.

Do silver fish leave on their own?

No, silverfish do not disappear spontaneously. As long as conditions are favourable (humidity, dark hiding places and food available), they will remain and reproduce. Even if you see fewer of them for a while, it is highly likely that they are hiding elsewhere (skirting boards, pipes, cracks).
Without targeted treatment, the infestation will almost always return.

How long does a silverfish live?

Silverfish live for an average of 3 years and up to 8 years.
This longevity explains why they are difficult to eradicate:
– they can survive for long periods without eating,
– they reproduce slowly but steadily,
– they can remain hidden for several months before reappearing.

What do silver fish eat?

Silverfish are omnivorous insects that feed mainly on materials rich in starch, sugar or cellulose.

They consume, in particular:
– paper, cardboard, books and newspapers,
– glue (wallpaper, bindings, cardboard),
– dust and organic residues,
– mould and microalgae associated with humidity,
– certain natural textiles (cotton, linen, silk),
– food residues that have fallen on the floor (flour, sugar, crumbs).

How to recognise a food moth infestation: instructions

Food moths are insects that feed on our food and reproduce very quickly. An infestation can go unnoticed for several days, as the eggs and larvae hide in corners, drawers or directly in your dry food. The sooner you identify the problem, the easier it is to get rid of it.

To help you, here are our tips for quickly recognising food moths at every stage of their life cycle.

Where do food moths come from?

Contrary to popular belief, food moths (sometimes called moths) do not necessarily come from poor hygiene. They most often arrive with the food itself.

Here’s how they get into your home:

Products already infested in the shop: microscopic eggs can be found in a packet of flour, rice or cereal.
Eggs present in packaging: even if unopened, a packet may contain eggs laid during packaging.
Originating from another home: adult moths can move from one flat to another, especially in buildings with windows.

Once settled, female moths immediately look for a place to lay their eggs: they prefer dry foods (pasta, rice, flour, dried fruit, etc.), especially when stored in soft packaging that is easy to pierce.

Where do they hide?

Food moths like dry, dark places with little movement.

They are often found in:

poorly sealed jars,
cardboard or plastic packaging,
drawers,
corners and nooks of shelves,
under or behind food bags.

Do food moths build nests?

Unlike other insects, food moths do not build “nests” in the traditional sense. They do not construct organised structures, but simply lay their eggs in suitable locations.

Food moths or clothes moths?

Criteria	Food moths	Clothes moths
Where can they be found?	Kitchen cupboards, jars, packets, drawers, nooks and crannies	Cupboards, wardrobes, carpets, woollen textiles
What they eat	Dry foodstuffs: flour, pasta, rice, cereals, dried fruit	Natural textile fibres: wool, silk, feathers, fur
Appearance of the adult butterfly	Small brown or grey butterfly measuring 1 to 1.5 cm	Small golden yellow or beige butterfly measuring 0.8 to 1 cm
Appearance of larvae	Whitish, approximately 1 cm in size, present in food	White or cream, in fabrics or carpets
Signs of infestation	Silky threads in packages, moths in the kitchen, larvae in foodstuffs	Holes in clothing, fibrous dust, small cocoons on fabrics
Spawning area	Directly in foodstuffs or packaging	In textiles, seams, wool
Health hazard	Low (potential allergy risks)	No immediate danger
Risk of rapid infestation	Very high (females lay up to 300 eggs)	Medium to high (slower growth)

Recognising an infestation according to the 4 stages of development

Stage 1 – Food moth eggs

Food moth eggs are very difficult to spot, even when you know there is an infestation.

What do these eggs look like?

Size: approximately 0.3 to 0.5 mm, invisible to the naked eye.
Colour: off-white to pale yellow.
Location: always deposited in contact with food, as the larvae feed immediately after hatching.
Hatching time: 4 to 7 days: heat (between 20 and 30°C) promotes faster hatching.

Most infestations are caused by eggs already present in food at the time of purchase. This is why moths can be found even in perfectly clean cupboards..

Good to know: a female butterfly can lay 200 to 300 eggs in a single batch.

Stage 2 – Food moth larvae

Food moth larvae are the most problematic stage for several reasons:

they devour your food, cereals and dried fruit
they spin webs that contaminate the entire food supply
they move out of the packets to pupate in cupboards

What do the larvae look like?

Colour: whitish to cream, sometimes slightly translucent
Size: 5 to 15 mm depending on age
Shape: elongated body, darker head
Mobility: they move slowly and squeeze into corners, folds in packages or even under poorly closed lids
Duration in larval form: 2 to 4 weeks

How can you spot them?

As they move around, the larvae leave silky threads in dry food (like small spider webs).

Stage 3 – The moth chrysalis

After the larval stage, the food moth transforms into a chrysalis. At this stage, the infestation in your kitchen is well established.

Moth larvae seek out dry, dark and undisturbed places to pupate.

They often settle in:

The corners of cupboards and shelves
The corners of drawers
Under or behind infested packages
Hinges and hard-to-reach areas
Along skirting boards or on the ceiling of the cupboard

These cocoons can remain in place for several days before the moth emerges to take its adult form..

Stage 4 – Adult food moth butterflies

The adult food moth is a brown-grey butterfly measuring approximately 1 cm. It is an insect that flies slowly and erratically. These butterflies do not eat your food, but they reproduce by laying eggs. You can usually see them around kitchen lights, window sills, open cupboards or when you lift up an infested packet.

When you see one or more adult moths, it’s time to give your kitchen a thorough clean.

What to do in case of a food moth infestation?

If you spot larvae, silky threads, moths or cocoons in your cupboards, you need to act quickly: a food moth infestation will never disappear on its own.

The priority is to remove contaminated food, clean thoroughly and then protect your food in airtight containers.

How to get rid of clothes moths: instructions

Have you noticed holes in your clothes and textiles? Moths have probably taken up residence in your cupboards and drawers. It is best to act quickly, as these small butterfly-like insects can lay up to 200 eggs in their lifetime! So, how can you get rid of clothes moths quickly? How can you prevent them from coming back? Follow our advice.

Key takeaways

➡️ It is not adult moths that make holes in clothes, but their larvae.
➡️ A female clothes moth can lay up to 200 eggs in her lifetime.
➡️ Clothes moths love dark, dry places that are undisturbed.
➡️ ️ The first signs of infestation are: irregular holes, small whitish larvae, cocoons, fibrous dust, or moths flying around when you open the wardrobe.
➡️ To get rid of moths, you need to treat the fabrics, clean the entire wardrobe thoroughly, and then install natural repellents or pheromone traps.

Clothes moths: introduction

Clothes moths, also known as textile moths (Tineola bisselliella), are small pests that attack natural fibres directly.

A four-stage life cycle

1. Eggs

Females lay up to 200 eggs directly on textiles or in the corners of wardrobes. The eggs are tiny and invisible to the naked eye.

2. Larvae

It is the larvae that hatch from the eggs that make holes in your clothes. They feed on keratin, a protein found in:

wool,
untreated cotton,
silk,
cashmere,
feathers and fur.

They then dig the famous moth holes in clothes, throws, carpets or blankets. Clothes that have been stored for a long time without being washed or protected are the first to be affected.

3. Pupae

The larvae wrap themselves in a cocoon to transform. These cocoons are sometimes visible in the folds or corners of furniture. Generally, these chrysalises are found in dark places such as cupboards, drawers or under carpets.

4. Adult moths

Adult moths have a short lifespan. Their only role is to lay eggs, not to eat textiles.

Good to know: clothes moths can withstand high temperatures of up to 35°C.

Where do clothes moths hide?

Clothes moths prefer places that are:

dry and dark,
warm,
undisturbed.

They are mainly found in:

chests or trunks that are rarely opened.
cupboards,
drawers,
corners of wardrobes,
wardrobes,
non-airtight storage boxes,
chests or trunks that are rarely opened.

Why do clothes moths move into your home?

1. You bring contaminated textiles into your home

Clothes moths can easily find their way into your home via:

Clothes bought in second-hand shops or flea markets, not washed before storage.
Textiles that have been stored in the attic or basement for a long time.
Rugs, throws, blankets or cushions picked up from a friend or relative.
Textile items stored in boxes, which may harbour larvae.

➡️ In 80% of cases, it is the larvae already present in the fibres that trigger the infestation.

2. Your textiles are not being cared for properly

Poorly washed linen, dust, dirty clothes and a lack of ventilation are all factors that encourage the development of mite larvae.

Good to know: Larvae are particularly fond of textiles containing traces of perspiration, sebum, food residues and body odours.

Mistakes that encourage moth infestation

❌ Leaving dirty clothes in a basket.

❌ Keeping textiles in the dark for long periods of time.

❌ Storing fabrics in cardboard bags.

❌ Never airing out cupboards.

❌ Leaving clothes in corners or closed drawers for several months.

5 steps to permanently get rid of clothes moths

Step 1: Treat textiles

If the fabric allows it, wash your clothes in the washing machine at 60°C.

The heat will destroy the larvae, mouthparts and eggs hidden in the fibres.

Instructions:

Wash your infested clothes at a minimum temperature of 60°C (excluding wool).
Then dry them in the tumble dryer at a high temperature for 30 minutes to complete the treatment.
Iron if possible: the heat from the iron helps to eliminate any remaining larvae in the folds.

👉 Ideal for: cotton, sheets, towels, non-delicate clothing.

For wool, cashmere, silk or any delicate fabrics, opt for freezing.

Instructions for use:

Place the garment in an airtight bag.
Freeze at -20°C for at least 72 hours.
Allow to return to room temperature without opening the bag to prevent condensation in the fibres.

Step 2: Clean the wardrobe

After treating your clothes, you need to clean cupboards, wardrobes and drawers, as clothes moths like to hide in corners to lay their eggs and pupate. Without this step, the infestation may return.

Using the nozzle attachment on your vacuum cleaner, start by thoroughly vacuuming every nook and cranny: drawer corners, hinges, under shelves, cracks in the wood, etc.

Then throw the bag away in an outside bin.

Final step: clean with white vinegar.

Mix 50% hot water + 50% white vinegar.
Clean all surfaces of the wardrobe: walls, shelves, drawers, uprights, hinges.
Pay particular attention to corners and areas where dust accumulates.

Good to know: vinegar removes odours and pheromones that attract moths.

Step 3: Use natural repellents

Once your clothes have been treated and your cupboards cleaned, the next step is to prevent clothes moths from returning.

Here are some natural “old wives” remedies’ that work.

1. Cloves

The strong smell of cloves repels moths.

How to use them:

Place a small handful of cloves in a piece of gauze, a cotton bag or muslin.
Place several of these in your cupboards, drawers, suitcases and dark corners.

⚠️ Avoid direct contact with delicate fabrics, as the cloves can leave a lingering odour.

2. Red cedar balls

Red cedar gives off a woody scent that moths hate.

How to use them:

Lightly sand the surface of the wood every 2–3 months to reactivate its scent.

How to use them:

Place a few drops on a cotton ball, porous pebble, or small wooden disc.
Place them in cupboards or drawers, without direct contact with your textiles.
Repeat every 2 to 3 weeks.

⚠️ Never apply essential oil directly to your clothes, as the stains are irreversible!

3. Repellent essential oils

Certain essential oils are very effective as natural repellents:

True lavender
Peppermint
Eucalyptus radiata

How to use them:

Place a few drops on a cotton pad, porous pebble or small wooden disc.
Place them in cupboards or drawers, without direct contact with your fabrics.
Repeat every 2 to 3 weeks.

⚠️ Never apply essential oil directly to your clothes, as the stains are irreversible!

4. Lavender and thyme sachets

Dried lavender and thyme give off a scent that moths do not like.

How to use them:

Place lavender or thyme sachets in drawers, between stacks of laundry or on shelves.
Replace them every 2 to 3 months to maintain the scent.

5. Pieces of Marseille soap

Marseille soap is a traditional repellent that is very effective against clothes moths.

How to do it:

Cut a few pieces of dry soap.
Place them in your wardrobes and drawers.
Avoid direct contact with wool or silk to prevent the scent from becoming too strong.

Step 4: Use pheromone traps and trichogramma wasps

Pheromone traps

Pheromone moth traps attract male moths with a synthetic scent that mimics the sex pheromones of females. The male sticks to the adhesive surface and cannot fly away.

This method has the advantage of being insecticide-free and effectively regulates moth reproduction.

Trichogramma wasps

Trichogramma wasps are tiny microscopic insects, completely harmless to humans, which parasitise moth eggs.

They prevent the larvae, which are responsible for holes in clothing, from hatching.

They disappear naturally after about ten days once the eggs have been consumed.

Trichogramma wasps are often sold in the form of small cards to hang up, which should be replaced every 2 to 3 weeks. You can place them near areas where moths lay their eggs: seams, corners, under shelves.

This 100% natural, insecticide-free method is highly effective in stopping an infestation at an early stage.

Step 5: Store your clothes properly

Clothes moths love cupboards and drawers, but they cannot get into a truly airtight container.

Here are the most effective solutions:

Mothproof zippered covers

These covers are ideal for protecting delicate or rarely used garments: woollen coats, cashmere jumpers, suits, winter clothes, etc.

They prevent moths and their larvae from accessing the fabric fibres while also protecting against dust and moisture.

➡️ Practical tip: Place a lavender sachet or a small cedar ball inside, ensuring it does not come into direct contact with the garment.

Airtight boxes

These are perfect for long-term storage or delicate fabrics (wool, silk, alpaca, cashmere). Choose thick plastic boxes with silicone seals.

Tips for preventing clothes moth infestation

✅ Air out your wardrobes once a week.

✅ Wash clothes before storing them.

✅ Place natural repellents in cupboards.

✅ Store clothes in covers.

✅ Avoid stagnant humidity.

✅ Regularly inspect textiles that are rarely worn.

FAQ

Are clothes moths dangerous?

No, clothes moths pose no danger to human health: they do not sting, bite or transmit any diseases.
The real problem is their larvae, which feed on natural fibres (wool, silk, cashmere, feathers, etc.) and can cause significant damage to your wardrobes.
They are therefore harmful to your clothes, but not to your health.

How can I tell if the holes in my clothes are caused by moths?

Here are some clues that confirm that you are dealing with clothes moths:
– Irregular holes in clothing, often clustered in an inconspicuous area.
– Fibrous dust left behind by larvae as they nibble on fabric.

How long does a clothes moth live?

Lifespan depends on the environment and temperature, but it is estimated that adult butterflies live for 1 to 2 weeks, just long enough to reproduce.

Do moths attack clean clothes?

Yes, clean clothes can be attacked if:
– they contain tiny traces of perspiration,
– perfume residues, sebum or dead skin cells,
– or if they are made of animal fibres (wool, silk, alpaca, cashmere, etc.).

How to get rid of food moths?

Have food moths invaded your kitchen? These pesky little moths love to hide in our cupboards in search of food. How can you recognise a moth infestation and, more importantly, how can you get rid of them for good? Follow our advice.

Step 1: Empty all infested cupboards and drawers

Start by emptying your cupboards and drawers completely, even if the infestation seems to be limited to a single packet. Food moths move quickly, lay their eggs in corners, and their larvae can hide in unexpected places.

Inspect each food item one by one.

Do not hesitate to throw away any suspicious food, especially dry goods that moths love:

pasta
rice
flour
cereals
seeds and oilseeds
dried fruit
semolina
breadcrumbs
biscuits, cakes, chocolate

Good to know: even a sealed package can be infested. Packaging can be contaminated during the manufacturing process.

Before throwing away infested food, place it in a sealed bag and put it directly into the outside bin. This will prevent moths or larvae from escaping and re-colonising the kitchen.

Step 2 – Clean thoroughly

Once your cupboards are empty, it’s time to clean. The aim is to eliminate eggs, larvae, pupae and moths.

Vacuum every nook and cranny

Use the narrow nozzle of the vacuum cleaner to clean:

hinges,
cupboard corners,
drawer runners,
shelf fixing holes,
silicone seals.

⚠️ Important:

Immediately dispose of the vacuum cleaner bag in a sealed bag and then in the outside bin to prevent re-infestation.

Wash surfaces with hot soapy water and then white vinegar

Use hot water + a few drops of washing-up liquid, then rinse. Leave to dry completely before applying white vinegar.

White vinegar is THE product to have in your kitchen. It cleans, eliminates odours and repels moths thanks to its acidic smell.

How to use it:

Mix 50% hot water + 50% white vinegar.
Soak a sponge or cloth.
Clean all surfaces: shelves, walls, undersides and tops of boards.

Step 3 – Apply a natural repellent

Once the cupboards are dry, you can add natural repellents:

bay leaves,
cloves,
lavender or mint sachets,
a few drops of true lavender essential oil on a cotton pad (avoid direct contact with skin and eyes).

These scents are known to repel food moths.

Step 4 – Freeze certain products

Freezing allows you to:

kill any larvae still present,
destroy eggs before they hatch,
make food safe before putting it back in your cupboards.

If necessary, you can freeze all dry goods that tolerate cold temperatures well: cereals, seeds, almonds, nuts and other dried fruits, etc.

Place them in your freezer for at least 48 hours. Allow them to return to room temperature without opening the bag to prevent condensation. Then transfer the food to an airtight glass jar before storing it in your cupboards.

Step 5 – Store in airtight containers

Be careful, food moths are capable of piercing certain types of packaging, infiltrating tiny nooks and crannies, and even getting into sealed packages. Therefore, nothing can replace airtight containers.

Which containers should you choose?

✅ Glass jars with mechanical closures

✅ Food-grade plastic boxes with silicone seals

✅ Airtight metal containers (tea, semolina, flour)

How can you recognise a food moth infestation?

Food moths are pests that feed on our food supplies and reproduce very quickly. An infestation often starts discreetly, then spreads to all the cupboards, drawers and kitchen cabinets.

Here’s how to identify them quickly.

Presence of larvae

It is the larvae of food moths that are responsible for contaminating food.

They can be recognised by:

their whitish or cream colour, sometimes slightly translucent,
their small size (10 to 15 mm),
their slow movement in packets, jars or corners of furniture,
the presence of silky threads (webs) in food: flour, pasta, muesli, dried fruit, rice, etc.

They love to lay their eggs in dry foods and can squeeze through even the thinnest packaging.

Good to know: you can also purchase contaminated batches directly in shops.

Grey moths in the kitchen

Adult moths resemble small brown-grey moths measuring approximately 1 cm.

You may see them:

flying around lights in the evening,
resting on cupboard walls,
coming out of infested packages when they are moved.

They will readily enter poorly sealed jars, attracted by the smell of cereals and other starchy foods.

How long does it take to get rid of food moths?

It often takes 3 to 4 weeks to permanently solve the problem. Even after a thorough cleaning, a single egg or larva is enough to restart the cycle.

For your information, a food moth goes through four stages:

1. Egg

Deposited on foodstuffs or at the bottom of packages.

➡️ Hatching: 3 to 7 days depending on the temperature.

2. Larva

It feeds and burrows tunnels in the food.

➡️ Duration: 2 to 4 weeks on average.

3. Chrysalis

The larva hides in a corner of the ceiling, cupboard, behind a package or in a crack.

➡️Metamorphosis into a pupa: 4 to 10 days.

4. Adult moth

Males fly, females lay up to 300 eggs in a few days.

Natural solutions against moths

Natural method	What moths dislike	How to use it
Repellent odours	Lavender, mint, eucalyptus, cloves, bay leaves	Place sachets, small dried bouquets or bay leaves in cupboards, drawers and corners.
Essential oils for moth repellent	True lavender, peppermint, eucalyptus, lemongrass	Place 2-3 drops on a cotton pad, diffuser or absorbent paper and place in cupboards or wardrobes.
Repellent plants and spices	Laurel, cloves	Place a few bay leaves in closed jars and cupboards; arrange cloves in a small dish.
White vinegar	Very unpleasant acidic odour for moths	Clean the shelves with a mixture of white vinegar and water, possibly combined with 1 drop of essential oil.

➡️ See also: How to get rid of clothes moths?

How can you prevent moths from returning?

Store all food in airtight containers (glass, metal, thick plastic).
Clean cupboards once a month with white vinegar (shelves, corners, hinges).
Regularly inspect sensitive products: flour, rice, pasta, dried fruit, seeds, cereals, biscuits.
Install pheromone traps to monitor and detect the first male moths.
Use natural repellents (bay leaves, cloves, lavender or mint essential oils).
Clean up crumbs immediately and avoid leaving open packets in cupboards.

FAQ

Do moths get into jars?

No, food moths cannot enter a truly airtight jar (glass + rubber seal + tightly closed lid).
However:
– they can lay eggs on the lid,
– they can infest a jar that is not closed properly,
– they may already be present in the food (eggs laid in the factory or during transport).

What is the smell that moths dislike?

Food moths are sensitive to strong, aromatic odours.
They particularly dislike:
– Lavender
– Peppermint
– Eucalyptus
– Cloves
– Bay leaves

These odours act as repellents, but do not eliminate an infestation.

Are food moths dangerous to health?

No, food moths are not dangerous to human health. They do not bite, transmit diseases or contaminate the ambient air.

Is it dangerous to consume products contaminated by moths?

Some people may be allergic to the proteins found in the droppings or body fragments of these insects. Skin irritation (itching, redness) or respiratory irritation (coughing, breathing difficulties) may occur.
Gastrointestinal problems may also occur, such as nausea, abdominal pain or diarrhoea. These symptoms are generally mild and temporary.
