Essential oils: a natural repellent with multiple properties

Essential oils are valuable allies in repelling bed bugs. Certain varieties give off a powerful odour that drives these pests away. In addition to their repellent effect, they have soothing properties that are ideal for calming bites and itching caused by bed bugs.

In summary, they can:

✅ Spread a natural odour barrier throughout the room or bedding;

✅ Help relieve irritated skin after bites;

✅ Complement a comprehensive treatment for mild infestations.

What essential oils cannot do alone

Please note that essential oils alone are not enough to eliminate an infestation. Bed bugs nest in every nook and cranny of mattresses, bed bases, sheets and furniture, and can lay eggs that are invisible to the naked eye. Applying oils does not always reach them.

⚠️Some oils may be irritating to children, people with asthma or pregnant women.

Before any application, it is therefore necessary to:

• Do not diffuse in the presence of infants.
• Always dilute in water or vegetable oil.
• Avoid contact with the eyes and mucous membranes.

The 7 most effective essential oils for bed bugs

1. Lavender essential oil (Lavandula angustifolia)

Known for its soothing properties, lavender is also effective against pests. Its floral scent is highly unpleasant to bed bugs. In addition, it calms the itching associated with bites.

💡 How to use it?

Here is a recipe for a lavender repellent spray:

• 500 ml of warm water
• 40 drops of true lavender essential oil
• 10 drops of tea tree essential oil (to enhance the anti-parasitic effect)

➡️ Frequency: once a day for 7 to 10 days in case of infestation, then twice a week for maintenance.

6. Rose geranium essential oil

Its floral scent is unpleasant to many insects, including bedbugs. It is an excellent ally for deodorising the home while naturally combating pests.

💡 How to use it?

Here is a recipe for a rose geranium bedbug spray:

• 500 ml of warm water
• 30 drops of rose geranium essential oil
• 10 drops of true lavender essential oil (optional, to soothe bites and enhance the repellent scent)

➡️ Frequency: one application per day for 7 to 10 days, then every 2-3 days for maintenance.

Does your home insurance cover you if you have bed bugs in your home? Beyond the health issue, the question of liability and reimbursement of treatment costs is extremely important (for both tenants and landlords). To help you see things more clearly, here is a practical guide to bed bug insurance.

What you’ll find in this guide:

• An overview of the existing legislation
• The best insurance policies available on the market
• Coverage and guarantees offered by these policies
• Prices for this type of protection

Bed bugs: who is responsible, the tenant or the landlord?

Who should pay for pest control treatment in the event of a bed bug infestation? The answer depends on several factors, including when the infestation is detected and the evidence available as to its origin.

Landlord obligations

Since the ELAN law came into force in 2018, landlords are required to provide decent accommodation, free from pests such as bed bugs. If an infestation is found shortly after the tenant moves in (between 6 months and 1 year), it is generally assumed that the bed bugs were present before the tenant arrived. In this case, the landlord is responsible for the treatment costs.

➡️ Best practice: Before renting out a property, landlords can call in a dog detection company to confirm whether or not bed bugs are present.

Tenant responsibilities

If the infestation is detected several months after moving in, the situation becomes more complex. The tenant may be held responsible if the landlord can prove that the infestation was the result of negligence or lack of maintenance on their part. For example, if evidence indicates that the tenant brought the bedbugs into the property via infested luggage or furniture, they may be required to cover the costs of pest control.

In practice, providing this type of evidence is very difficult for landlords. In most cases, they are responsible for covering the costs of treatment.

Bed bug treatment: a high cost

According to ANSES, the fight against bed bugs costs an average of €866 (source).

Several factors explain this cost:

• It often takes at least two visits to eliminate all stages of development (eggs, nymphs, adults).
• Professionals must use specific equipment (dry steam, certified products, protective suits, etc.).
• The treatment takes a long time, often several hours per visit, with significant diagnostic and preventive work.

In addition, don’t forget the associated costs, such as furniture that has to be thrown away or repaired.

Be careful, although the cost may seem prohibitive, doing nothing will cost even more: multiple treatments, the need to throw away mattresses and furniture, or even temporary rehousing.

In principle, insurance that covers bed bugs is therefore useful.

Should you (really) take out bed bug insurance?

With infestations on the rise in France, it’s a question that inevitably arises.

In principle, specific insurance can save you a lot of money. However, here’s what you need to know before taking out a policy.

Chemical treatments are not always effective

Despite their high cost, professional chemical treatments do not always guarantee complete eradication of the problem. Why?

• The eggs are highly resistant to conventional insecticides, often requiring two treatments.
• Some strains of bedbugs develop resistance to chemicals.
• In the event of an advanced infestation, the property may require several treatments at short intervals, which can increase the cost.
• There are many scams on the market.

As a result, you may end up with very high costs for a problem that is not solved.

Before calling in a pest control professional, carry out mechanical and heat treatment (wash clothes at over 60°C, steam clean, etc.).

👉 For more information: Bed bugs: the complete treatment protocol.

Tenants and landlords: financial assistance available

If you are a tenant: financial assistance from the CAF (family allowance fund) can cover your disinfection costs up to €600. However, you must be receiving benefits to be eligible.

If you are a homeowner: a subsidy from the ANAH can cover up to 50% of treatment costs, up to a limit of €10,000, subject to income and energy performance criteria.

👉 For more information: Bed bugs: government support measures.

Virtually non-existent protection from traditional insurers

Most traditional insurers do not include this type of claim in their basic cover, as they consider pest infestations to be:

• events that are part of routine home maintenance;
• non-random risks, since bedbugs often spread through negligence (lack of vigilance after a trip, purchase of infested furniture, etc.);
• problems that are not sudden or accidental, unlike water damage or burglary.

Very limited coverage, even as an option

Some policies may offer assistance coverage:

• Contact with a pest control professional.
• Temporary logistical assistance (re-accommodation, childcare, etc.).
• But again, no direct coverage of treatment costs, unless there is an exceptional clause.

A gradual awareness

With the explosion of cases in France and the insistence of the public authorities, some insurers are beginning to consider specific offers. But to date, apart from neo-insurers and specialised start-ups, the major companies remain cautious.

Online neo-insurers: a response to new expectations

New 100% online insurance platforms have decided to tackle the problem of bed bugs. Their goal is to offer tailor-made policies that are more flexible and better suited to this type of everyday claim.

Luko, Friday and Badbugs are start-ups that stand out for:

• Explicit coverage of bed bug treatment costs.
• A simplified procedure via an app or online interface.
• Greater responsiveness in emergencies, sometimes with rapid dispatch of a certified professional.
• Competitive rates, tailored to young professionals and urban dwellers.

As you have no doubt noticed, cases of bed bug infestation are on the increase, both in our homes and in public places. With the explosion in travel, global warming and a lack of knowledge about the subject, these little blood-sucking insects have found ideal conditions for spreading. The fight against this public health problem is being organised, starting with a thorough understanding of the biology and behaviour of bed bugs. Biological characteristics, lifestyle, reproduction: here is everything you need to know about Cimex lectularius. The aim is to understand them better in order to eliminate them more effectively.

The biological characteristics of bed bugs

These tiny but formidable insects have biological characteristics that explain their ability to adapt and proliferate in our homes.

According to an ANSES report, between 2017 and 2022, 11% of households in France were contaminated by bed bugs (source).

Cimex lectularius: the most common species in France

In France, the most common species of bed bugs is ‘Cimex lectularius’. For your information, there are two species on earth: ‘Cimex lectularius’ and ‘Cimex hemipterus’, which are part of the ‘Cimicinae’ subfamily.

Its main characteristics:

• Biting-sucking insect: it feeds solely on human blood to survive and develop.
• Oval, flattened body: handy for slipping into the smallest cracks, mattress seams, furniture or skirting boards.
• Adult size: apple seed.
• Nocturnal activity: bedbugs avoid light and mainly come out at night, when their host is still and asleep.
• Incapable of jumping or flying: unlike other pests, they only move by walking.
• Life expectancy: 6 to 12 months.

There are a few natural predators such as the common swift.

An insect that feeds exclusively on human blood

At each stage of its life, bed bugs need to feed on blood in order to survive.

What you need to know about their diet:

• Bed bugs must feed on blood before each moult.
• Average duration of a meal: 10 minutes.
• Time between 2 meals: 5 to 15 days.
• Both males and females bite.
• They are attracted to the CO₂ given off by our breathing and to our body odours, not directly to blood.

Good to know: Their saliva contains an anticoagulant that liquefies the blood and facilitates the meal. It also contains histamine, which is responsible for local inflammation and therefore for the appearance of the famous red spots.

Can they bite animals?

Even though Cimex lectularius clearly prefers humans, some related species can also bite bats or birds. But in a domestic environment, bed bugs feed almost exclusively on human blood.

Life cycle of bed bugs: from eggs to adults

Like all insects, bed bugs have a life cycle consisting of several stages, from tiny eggs to adults capable of reproducing.

Temperature plays a key role in the development of bed bugs. The warmer it is, the faster they develop. Conversely, low temperatures greatly slow their growth.

Key points to remember about the life cycle of bed bugs

➡️ Each adult female lays an average of 3 to 5 eggs per day.

➡️ A bed bug goes through 5 immature stages called nymphs (falsely referred to as larvae of bed bugs).

➡️ With each moult, a blood meal is essential to move on to the next stage.

➡️ The eggs are extremely resistant to conventional insecticides because of their waxy shell.

➡️ Temperatures strongly influence the speed of development:

• At 28°C: a complete cycle (egg → adult) lasts 45 days.
• At 18°C: the cycle is slowed to around 100 days.
• At 13°C: the evolution can take up to 5 months.

Lifestyle of bed bugs

Discreet, tenacious and perfectly adapted to the human environment, bed bugs develop very specific behaviours to survive and multiply.

Insects that live exclusively alongside humans

Cimex lectularius is a parasitic insect strictly linked to humans: it does not naturally live outside (except in exceptional conditions). It seeks out the proximity of a human host in order to feed on blood (it is a haematophagous insect at all stages of its life).

They are essentially nocturnal: they flee from light and mainly come out at night, when the host is immobile. When a population becomes too large, they can sometimes be seen during the day.

Where do bed bugs hide?

Their objective: to stay as close as possible to their food source (humans), in dark, narrow and difficult to access places.

They are mainly found:

• In clothing, curtains, bags or luggage in the event of an advanced infestation.
• In the seams of mattresses and box springs.
• Behind skirting boards, cracks in walls or furniture.
• Under bed slats, in the gaps of furniture.
• Behind headboards, frames, pictures or electrical sockets.

How do bed bugs move?

A bed bug moves quickly when walking. It does not fly or jump.

These insects can migrate from room to room through cracks, ducts, sockets or furniture.

In a building, they will move from floor to floor through pipes, electrical ducts, air conditioning systems, etc. They can also attach themselves to the clothes and other fabrics of the occupants.

Also beware of the presence of bed bugs in hotels or Airbnb accommodation.

How do they communicate?

Bed bugs use aggregation pheromones to group together in hiding places.

They are also guided by:

• The CO₂ released by human respiration.
• Body heat.

Reproduction of bed bugs

The reproductive capacity of bed bugs is one of the main reasons for their rapid proliferation. The cycle is short, there are numerous egg-laying episodes and the eggs are particularly resistant.

These eggs are tiny (1 mm), white and covered with a waxy layer that makes them very difficult to remove or kill with conventional insecticides.

A specific behaviour: traumatic insemination

Bed bugs mate in a particular way. The male directly pierces the female’s abdomen to inject his sperm. This is known as traumatic insemination. This method of reproduction is extremely aggressive for the female, which explains why some of them leave the nest to form satellite colonies in other areas of the home. For information, in a population of bed bugs, there are approximately 60% males and 40% females.

Satellite colonies: behaviour that causes massive infestations

When an infestation becomes significant, the females flee areas that are too crowded or too exposed to the males. They hide in other quieter places (distant furniture, other rooms, clothes, bags, etc.).

This is how the infestation gradually spreads throughout an entire apartment, building or even a hotel.

Effective treatment measures

When faced with an infestation of bed bugs, a partial or approximate treatment is often doomed to failure. To get rid of these insects for good, it is essential to combine several complementary techniques, following a rigorous protocol.

Thermal treatments: steam and cold

Extreme heat and cold are the only truly effective methods against all stages of development, including eggs.

Heat treatment

Use a dry steam cleaner (minimum 120°C). Direct contact with steam instantly kills bed bugs, larvae and eggs.

Important: steam is effective up to a maximum distance of 5 cm. Beyond that, it loses its lethal power.

Cold treatment

Place contaminated objects in the freezer at -20°C for at least 72 hours. Warning: freezing for 24 hours is not enough. Bugs can survive at -20°C if the time is too short. This type of treatment eliminates bed bugs, their larvae and their eggs.

Diatomaceous earth: a natural and long-lasting treatment

Diatomaceous earth is a mineral powder that acts by mechanical means. It kills and dries out bed bugs in 4 to 5 days.

It is particularly useful for areas that are difficult to access: behind skirting boards, in electrical sockets (only in sachets), under furniture, etc.

Good to know: clay from Somme is effective in killing bed bugs.

Vacuuming: an essential daily task

Vacuum thoroughly:

• Seams of mattresses and box springs
• Cracks in furniture and baseboards
• Dark corners where bed bugs like to hide

Then dispose of the contents in an airtight bag outside.

FAQ

Have you noticed small translucent or whitish larvae in your home? If they are bed bug larvae, sound the alarm! They indicate that an infestation is underway. How can you identify this type of larva? What are the best practices and effective treatments? Here is all the advice from Sereni-d.

How can I recognise bed bug larvae?

Bed bug larvae are the first visible sign of an infestation. Unlike adults, they are more difficult to spot because of their tiny size. 

Size and appearance of the larvae/nymphs

• Small size: Approximately 1 mm at hatching and up to 4 mm before they moult into the adult stage.
• Oval and elongated shape.
• Translucent colour, which becomes darker after their first blood meal.
• Soft and fragile body, unlike adults, which have a more rigid shell.

Difference with other insects

Bed bug larvae are sometimes confused with other pests.

Here are a few tips to help you avoid mistakes:

Life cycle of bed bugs: difference between larvae, nymphs and adults

Understanding the different stages of the life cycle of bed bugs allows you to react effectively. The ‘Cimex lectularius’ goes through several stages of development: eggs, five immature stages (nymphs) and then adult.

1. Bed bug eggs

• Size: Approximately 1 mm when hatched, almost invisible to the naked eye.
• Colour: Whitish, translucent, making them difficult to spot.
• Appearance: Resemble a grain of sticky rice.

They are mainly found in mattress seams, furniture cracks, behind skirting boards and in dark places.

A female can lay up to 5 eggs per day and around 500 in her lifetime.

2. Bed bug nymphs

As soon as the egg hatches, it becomes a nymph. This is the stage of immature development or ‘juvenile stage’, which takes place in 5 phases. It is from the immature stage that the bed bug needs to feed on blood to gradually progress to its adult phase.

• Size: 1.5 mm to 4 mm, growing progressively after each meal.
• Colour: Darker than the larvae, becoming light brown as they develop.
• Appearance: Resemble the adult, with the same number of legs and the same shape.

They moult five times before reaching adulthood, requiring a blood meal at each moult:

• 1st nymph stage (1.5 mm)
• 2nd nymph stage (2 mm)
• 3rd nymph stage (2.5 mm)
• 4th nymph stage (3 mm)
• 5th nymph stage (4.5 mm)

The term ‘bed bug larva’ is a linguistic flaw. A larva is used for insects in which the immature stage does not resemble the adult (such as butterflies). For bed bugs, we speak of ‘nymphs’, because the immature stages resemble the adult form.

3. Adult bed bugs

• Size: Approximately 5 to 7 mm, visible to the naked eye.
• Colour: Reddish brown and darker than nymphs.
• Appearance: Oval and flattened when hungry, but can swell after a meal.
• Reproduction: An adult female lays up to 5 eggs a day and more than 500 in her lifetime, accelerating proliferation in a few weeks.

How quickly can an infestation develop?

The higher the temperature, the faster the bugs develop.

• At 28°C, a larva becomes an adult in 45 days.
• At 18°C, the cycle lasts about 100 days.
• At 13°C, it takes almost 5 months to reach the adult stage.

Where do we find the larvae of bed bugs?

The larvae of bed bugs remain discreet and hidden in dark and difficult to access places. Unlike adults, they do not travel far and remain close to their main food source: humans.

1. Bedding

• Seams and folds in mattresses: larvae like to lodge in the nooks and crannies of mattresses and box springs.
• Gaps in box springs: they hide under the slats or in the cracks in the wood.
• Pillows and sheets: they sometimes leave traces of blood and black excrement visible on the bed linen.
• Headboards and bed frames: they find refuge in the cracks of the wood or behind the padded structures.

2. Furniture and objects near the bed

• Bedside tables and chests of drawers: larvae infiltrate the drawers or under the furniture.
• Sofas and armchairs: they lodge in the seams and under the cushions.
• Curtains and carpets: they like thick fabrics where they can hide.
• Electrical sockets and cracks in walls: the larvae can also infiltrate dark and inaccessible corners.

3. Clothing and luggage

• Bed linen and clothes: they can cling to fabrics and move with them.
• Luggage and travel bags: a frequent source of contamination after a stay in a hotel infested with bed bugs.

Other signs of infestation

In addition to the larvae, there are several signs that may confirm the presence of bed bugs in your home:

• Traces of bites: red bumps grouped in a line or cluster, often on the arms, legs and back.
• Black spots on the mattress and sheets: these are excrement left by the bedbugs.
• Presence of exuviae: the transparent moults of nymphs are often visible near hiding places.
• Unusual odour: an advanced infestation can give off a sweet or musty odour.

➡️ To find out more, you can consult the different levels of infestation established by the INELP. In addition, canine detection is very effective in detecting bed bugs.

How to kill bed bug larvae?

If you spot bed bug larvae in your home, you must act immediately to prevent them from becoming adults and reproducing. We recommend that you combine the following methods:

Mechanical and preventive treatments

• Vacuum clean: Pay particular attention to cracks in furniture, mattress seams, bed bases and dark corners. Dispose of the bag immediately or empty the bin into a sealed bag, which you should then place in an outside bin.
• Wash infested laundry: All exposed textiles (sheets, clothes, curtains) should be machine washed at 60°C, then tumble dried on high.
• Use a steam cleaner: Dry steam at 120°C kills larvae, nymphs and eggs instantly, especially in mattresses, box springs and wall cracks. Steam works up to 5 cm away, beyond that it is not effective.

➡️ See also: Bed bug traps.

Chemical treatments and insecticides

The diatomaceous earth SERENID: This natural product has a cutting action that dries out larvae and adults in 4 to 5 days. Apply it in corners, along baseboards and behind electrical outlets.

Thermal treatments

• Cold treatment: Place infested textiles and small objects in the freezer at -20°C for at least 72 hours to kill the larvae and eggs.

➡️ To go further: The complete protocol against bed bugs.

How can I avoid another infestation?

The best solution against bedbugs is prevention.

Here are some good practices:

• Avoid buying second-hand furniture without disinfecting it.
• Check your bedding regularly (seams, bed base, mattress).
• Apply diatomaceous earth behind electrical sockets, under the bed and along skirting boards.
• When travelling, store your suitcase high up.

FAQ

Bed bugs feed on human blood, but can they also bite our pets? Should dogs and cats be afraid of these pests? What are the right steps to take? Serenid answers all your questions on the subject. Let’s go.

⚠️ Important: This article is for information purposes only and is not a substitute for veterinary advice.

Can bed bugs attack animals?

Bed bugs (Cimex lectularius) feed mainly on human blood.

It is difficult for a bed bug to move through the hair of our domestic companions (the same goes for humans, bites do not occur in the hair). Moreover, bed bugs wait for the host to be still to feed, which is more complicated with animals that move much more.

➡️ Read also: The causes of bed bug infestation

Bed bugs in dogs

Bed bugs do not settle directly on a dog’s coat like fleas or ticks would. However, if they do not have access to a human host, they can bite a dog, especially in bald areas such as the stomach, the inside of the legs or the ears.

What to do?

• Clean its environment: Wash its blankets, cushions, baskets, toys and any other fabric items at 60°C to eliminate bedbugs and their eggs.
• Vacuum thoroughly: Vacuum its basket, carpets and areas where it usually sleeps. Immediately dispose of the vacuum cleaner bag in an airtight bin.
• Treat bites: Wash the bitten area with lukewarm water and mild soap. Apply a soothing cream or a suitable veterinary product, as advised by your vet.
• Protect your dog: During anti-bedbug treatments in your home, keep your pet away to avoid any exposure to chemicals or hazardous residues.

Bed bugs in cats

As with dogs, cats can also be bitten by bed bugs, although this is rare. Thanks to their dense fur, bed bugs find it more difficult to reach their skin. They therefore target less hairy areas such as:

• The inside of the legs
• The abdomen
• EarsBed bugs in cats

What to do?

• Wash its environment: Machine wash its blankets, cushions and all textiles at 60°C or put them in the dryer at a high temperature to eliminate bedbugs and their eggs.
• Change its litter regularly
• Vacuum frequently-used areas: Vacuum its basket, cat tree, carpets and sofas. Empty the bag and dispose of it immediately in an airtight bin.
• Monitor its behaviour: If your cat is scratching excessively or showing signs of stress, consult a vet.
• Protect your cat: During a bed bug treatment, keep your cat away from the treated areas to avoid exposure to chemical insecticides that are harmful to its health.

➡️ To go further: The complete protocol against bed bugs.

Bed bugs in birds

Bed bugs can also bite domestic birds such as chickens, although this is very rare. The most exposed areas are the parts of the body without feathers, such as the legs or around the eyes.

A bitten bird may show:

• Unusual agitation
• Swelling of the skin
• Lesions on the legs
• Ruffled plumage
• Weight loss due to stress and bites

Bed bugs can hide in birdhouses, litter, cages, under perches or in the corners of the room where the bird lives.

Good to know: Bird nests can be a source of bed bug contamination

What to do?

• Change the litter regularly
• Inspect the bottom and surroundings of the cage every day
• Remove accessories from the cage: branches, etc.
• Wash the cage
• Apply a treatment specifically for bed bugs

Bed bugs in reptiles

Bed bugs do not generally attack reptiles (snakes, turtles, lizards), as they do not provide ideal feeding conditions. These parasites prefer warm-blooded mammals, such as humans and pets.

However, in the event of severe infestation, bed bugs may seek refuge in terrariums/vivariums or under accessories such as heating pads and reptile hiding places.

What to do?

• Clean and disinfect the terrarium regularly
• Check every nook and cranny and cracks where bugs could be hiding
• Avoid using chemical insecticides that are harmful to reptiles (move them in case of treatment)

How can you recognise bed bug bites on a pet?

1. Appearance of the bites

• Small red or swollen bumps, often grouped in a line or cluster.
• Itching and irritation, more pronounced in sensitive animals.
• Affected areas: stomach, ears, muzzle, legs, areas with little hair.

➡️ Read also: Everything you need to know about bed bug bites.

2. Behavioural changes

• The animal scratches, nibbles or rubs itself more than usual.
• It shows signs of discomfort or restlessness, especially at night.
• Loss of appetite or unusual fatigue in case of severe irritation.

3. Differentiating bed bug bites from other parasites

• Fleas: Bites often scattered, intense itching and presence of small black dots (flea droppings) in the coat.
• Ticks: A single swollen lump with a tick attached to the skin.
• Lice: Rarer, more likely in farms and kennels.

Are chemical bed bug treatments dangerous for pets?

Yes, chemical bed bug treatments can be toxic to pets. Many insecticides used to eradicate these pests contain substances that are harmful to dogs, cats, birds and reptiles.

Above all, ask for advice from the professional who treats your home. They will be able to give you specific instructions: airing, washing at a high temperature, etc.

Opt for natural solutions

Chemical treatments should be a last resort and only used in the event of a serious infestation.

Above all, opt for natural treatments such as diatomaceous earth, anti-bug covers or high-temperature dry steam, which are safe for animals.

Dogs: a formidable weapon for detecting bed bugs

Thanks to their highly developed sense of smell, dog bed bug detectors are one of the most reliable ways to detect an infestation. In a few minutes, they are able to pinpoint the presence of these pests, even in hard-to-reach places such as mattresses, skirting boards or cracks.

Used by pest control experts, these specially trained dogs enable a quick and effective diagnosis, thus avoiding unnecessary treatments and directly targeting the infested areas. An effective solution to act quickly and limit the spread of bed bugs!

FAQ

Do animals transmit bed bugs to humans?

No, bedbugs do not live on animals and do not cling to their fur like fleas or ticks. They prefer fixed places (mattresses, skirting boards, nooks and crannies, etc.) to hide and wait for their blood meal.

What is the natural predator of bedbugs?

Skull crickets, geckos and certain beetles are predators of bed bugs. However, their presence in a house does not completely eliminate the infestation.

Can bed bugs hide in animal bedding?

No, bedbugs prefer dry, smooth surfaces such as mattresses, box springs and cracks in furniture. Your pet’s bedding is therefore not a favourable place for them to infest.

Do you have suspicious marks and stains in your bedding? Feces near the skirting boards? You may have bed bugs in your home. We don’t need to remind you, but this little pest, also known as ‘Cimex lectularius’, is often very difficult to live with on a daily basis. Early detection is therefore essential to avoid any proliferation. Here’s a practical guide to identifying the different types of marks and stains and spotting the presence of bed bugs in your home. You’ll also find a list of effective treatments for eradicating them.

How can you recognise traces of bed bugs?

Bed bug droppings and excrement

Bed bug droppings are one of the most telling signs of an infestation. These harmful insects feed exclusively on human blood, and their excrement, composed of digested blood residue, leaves characteristic traces.

Here’s how to identify them:

• Appearance: Droppings appear in the form of small black or brown spots, similar to ink blots. They are usually clustered near areas where bedbugs hide: mattresses, box springs, the seams of sheets or skirting boards.
• Location: Look for these marks around mattress seams, on pillows, in the crevices of the box spring, or on furniture close to the bed. These stains can also be found on walls or behind the headboard.
• Texture: Excrement is dry and spreads slightly when rubbed with a damp cloth, leaving a brownish mark.

The droppings are often accompanied by dead bedbug skins or whitish eggs. These are very revealing signs of an infestation.

Practical tip: If you find these marks, don’t ignore them. Vacuum the affected areas immediately, then use a high-temperature steam cleaner (minimum 100°C) to decontaminate thoroughly, and apply our FREEZE aerosol.

Traces of blood on bedding

At night, if you move around while you’re asleep, it’s common to crush bedbugs that are full of blood after their meal.

What’s more, a bedbug can absorb up to twice its own weight. When it has eaten too much, it can leave a trail of blood behind.

How do you clean bloodstains from bedding?

1. Act quickly: As soon as you spot a stain, treat it immediately before it dries, as fresh stains are easier to remove.
2. Use cold water: Soak the affected area in cold water. Avoid hot water, which can set the stain.
3. Apply bicarbonate of soda: Prepare a paste with bicarbonate of soda and a little water, apply it to the stain and leave for 30 minutes before rinsing.
4. Mild soap or stain remover: Apply a mild soap or stain remover specifically for blood stains (such as percarbonate-based products). Scrub gently with a soft bristle brush.
5. Wash at high temperature: Put stained clothes in the washing machine at 60°C to remove all traces of stain and reduce the risk of parasites spreading.
6. Natural option: You can also use white vinegar or lemon juice.

Use a bed bugs with mattress cover

You can protect your bedding with a special bed bugs with mattress cover. Similar to an anti-dust mite cover, it’s made from a multi-layered non-woven fabric. It forms a total barrier against bed bugs trapped inside. Some covers guarantee a micron-level seal for total protection.

Other signs of infestation

Bites and pimples

How can you recognise bed bug bites?

Bites are often concentrated in areas uncovered during sleep, such as the arms, legs, neck and face.

In terms of appearance, they take the form of small red pimples, often grouped together in a straight line or in clusters, and cause severe itching.

The itching and redness may persist for several days, or even a week, depending on the person’s sensitivity.

➡️ For more information: Bed bug bites: recognising and treating them.

No visible stings?

Bites alone are not always enough to confirm an infestation. They need to be cross-checked with other clues, such as traces of blood on bedding, droppings or bed bug eggs in the nooks and crannies of the bedroom.

Difference from other insect bites

• Mosquitoes: Mosquito bites are often isolated and larger, with immediate itching.
• Fleas: Fleas generally bite around the ankles and leave slightly raised spots.
• Mites: They cause diffuse redness, accompanied by constant irritation, rather than well-defined pimples.
• Pyemotes and scleroderms: These insects can also cause red pimples, but their bites are less frequent and occur on contact with infested textiles or grain.

What should you do if you are bitten by bed bugs?

• Do not scratch to avoid aggravating the itching or causing an infection
• Apply a soothing roll-on such as ROLL ON Serenid
• Wash the area with warm water and mild soap
• Consult a doctor if necessary

Bed bug eggs

Bed bug eggs and moults are clear signs of an infestation in your home. These traces are often left in places where bedbugs hide between their blood meals, such as bedding, cracks and dark nooks and crannies.

How can you recognise bed bug eggs?

• Size and appearance: Bed bug eggs measure around 1 millimetre, are white or translucent in colour and have an elongated, slightly oval shape. They look like small grains of rice.
• Location: They are generally found in the seams of mattresses, cracks in furniture, skirting boards and under bedsprings. Female bed bugs lay their eggs in hard-to-reach places.
• Number: A female can lay 5 to 7 eggs a day, with a total capacity of 200 to 500 eggs in her lifetime, which can quickly worsen an infestation.

Bed bug moults

Molts are the exoskeletons left behind by bed bugs as they grow from nymphs to adults.

They are light brown or translucent in colour and resemble immobile but empty bedbugs.

Like eggs, they are often found in bedbugs’ favourite hiding places, such as mattress seams, furniture crevices and dark corners.

What should you do if you find bed bug eggs or moults?

1. Vacuum infested areas, paying particular attention to mattress seams and crevices.
2. Use a high-temperaturesteam cleaner (at least 120°C) to kill the eggs.
3. Sprinkle diatomaceous earth in strategic nooks and crannies to prevent the eggs from hatching.
4. Follow up with a natural insecticide treatment such as Serenid spray.

The smell of bed bugs

One of the often overlooked but telling signs of a bed bug infestation is the distinctive odour they can give off.

Bed bugs give off a slightly sweet smell, sometimes compared to berries or a musty odour. This smell comes from their pheromones.

In the event of an advanced infestation, the smell becomes stronger due to the large number of bedbugs present and the accumulation of their faeces and excrement.

This odour is generally concentrated in areas where they hide, such as

• The seams of mattresses and pillows
• Cracks and nooks in furniture or walls
• Skirting boards and carpets near beds
• Box springs or headboards

Confirming the presence of bed bugs with dog detection

Dog detection is an effective and increasingly popular method of confirming the presence of bed bugs. Thanks to their exceptional sense of smell, trained dogs are able to spot bedbugs, even when they are hiding in hard-to-reach places.

Unlike a manual inspection, which can be long and tedious, a detection dog can inspect a room in just a few minutes. What’s more, dogs can target infested areas precisely, reducing the need for widespread, often costly, treatment.

Dog detection is particularly useful for early infestations, where other visual signs (eggs, droppings, moults) are still difficult to spot.

Once the bedbugs have been located, the professional will propose a suitable treatment plan.

With the explosion in tourism and travel, cases of bed bug infestation are becoming increasingly common in holiday lets. Airbnb accommodation is particularly affected, leaving travellers and owners often powerless to deal with the problem. What are the right things to do? Is it possible to get a refund? Who should pay for treatment? Here’s a practical guide to the subject of bed bugs in Airbnb accommodation.

How do you know if there are bed bugs in an Airbnb?

Before unpacking your bags and enjoying your Airbnb, it’s a good idea to check whether or not the accommodation is infested with bed bugs. Prevention is better than cure! Although these pests are often difficult to spot at first sight, they do leave some characteristic clues.

Here are the steps to follow to detect their presence:

1. Inspect the bed and bedding

Carefully examine the mattress, sheets, pillows and seams of the bed base. Look for traces of blood, black spots (droppings), whitish eggs or dead skin. Don’t forget to check the headboard and footboards.

2. Check the nooks and crannies

Bed bugs love to hide in cracks, skirting boards or furniture close to the bed. Use your phone’s torch to get a better look.

3. Detect an unusual smell

In the event of a major infestation, bed bugs give off a slightly sweet or musty smell due to their pheromones.

4. Keep an eye on your bites

If you notice bites grouped in rows or clusters on exposed areas of skin during the night, bed bugs are very likely to be present. These bites often cause intense itching.

In principle, bed bug bites are not dangerous to health, but they can cause allergic reactions.

What to do in the event of an infestation

Discovering bed bugs in an Airbnb can be very stressful. Don’t panic, here’s what you need to do to limit the damage.

Report the problem immediately

Contact your host and Airbnb customer service as soon as you suspect the presence of bed bugs. Take photos of any visible marks (black spots, bedbugs, eggs) and bites on your skin to support your report. Transparency is essential to avoid other travellers being affected as well.

Contact Airbnb user support

The Airbnb platform offers assistance for travellers.

Good to know: every booking on Airbnb includes AirCover protection, which means that in the event of a serious problem, you will be offered similar accommodation, subject to availability and at a comparable price.

Don’t move your luggage

Avoid placing your luggage on the floor, bed or surfaces close to infested areas. Place it on a metal support, such as a luggage rack, or in the bathroom, where bedbugs have fewer hiding places. In any case, up high! And lock your luggage at night.

Protect your personal belongings

Put your clothes and personal belongings in airtight plastic bags to keep bedbugs out. If you have any doubts, wash your clothes (worn or not) immediately at a minimum temperature of 60°C or freeze them at -18°C for at least 48 hours.

Inspect and clean your luggage

Before leaving your home, thoroughly inspect your suitcases and bags. Use a hoover to remove any eggs or bedbugs. Empty the contents of the hoover into an airtight bag and dispose of it outside.

Avoid carrying bedbugs home

When you return, take precautions to avoid contaminating your home. Unpack your luggage outside or in a tiled room that’s easy to clean, or even in your bathtub. Put your clothes in a tumble dryer at high temperature or use a steam cleaner on your luggage and textiles.

Don’t sleep in another bed in your home

Changing beds or rooms can worsen the infestation by dispersing bed bugs throughout the accommodation. It’s best to stay in the infested room until the host takes action.

Request a change of accommodation

If the infestation is confirmed and the host cannot resolve the problem immediately, ask to be rehoused.

• Use a steam cleaner: steam dry your luggage, textiles or other objects to disinfect them completely.

Bed bugs in an Airbnb: can you claim a refund?

Refunding your stay

Here’s how to proceed:

• Report the problem immediately within 72 hours of discovering it.

You can contact Airbnb user support by email, online chat or by phone on +33 1 84 88 40 00.

• Provide proof: photos or videos.

Good to know: In principle, the owner is obliged to provide pest-free accommodation. In the event of a proven infestation, payment will therefore be cancelled in full or in part.

Reimbursement of medical expenses

Medical consultations, antihistamines or antiseptic ointments – bed bug bites can cost money. Here again, travellers can request reimbursement of these costs.

Airbnb owners: what to do if your accommodation is infested by bed bugs

The use of Airbnb accommodation by French and foreign travellers automatically increases the risk of contamination. It should be remembered that the presence of these pests is in no way linked to a lack of hygiene.

➡️ For further information: The complete protocol against bed bugs.

Here’s what landlords should do if they find bed bugs in their Airbnb rental property.

Schedule a specialist response

Airbnb can help you coordinate the services of a company specialising in bed bug treatment. Dog detection is also a very effective method.

The professional who carries out the inspection in your Airbnb property must provide you with a detailed report following the inspection.

Carry out appropriate treatment

In the event of an advanced infestation, chemical treatment against bed bugs is necessary.

We recommend that you use a service provider with Certibiocide accreditation (certifying that technicians are properly trained to handle powerful insecticides). To avoid fraudulent intervention, here is a map of approved professionals.

Does home insurance cover bed bug treatment?

The extent to which home insurance covers bed bug treatment varies from policy to policy and from company to company. Generally speaking, standard home insurance policies do not cover the cost of eradicating pests, including bed bugs, as these operations are considered to be part of routine home maintenance.

You should therefore check the clauses of your home insurance policy and contact your insurer to find out whether such cover is included or can be added.
