All you need to know about bed bug larvae

Vous avez observé de petites larves translucides ou blanchâtres chez vous ? Attention, s’il s’agit bien de larves de punaises de lit, il faut tirer la sonnette d’alarme ! Elles indiquent en effet qu’une infestation est en cours. Comment identifier ce type de larves ? Quels sont les gestes à adopter et les traitements efficaces ? Voici tous les conseils de Sereni-d.

Comment reconnaître les larves de punaises de lit ?

Les larves de punaises de lit sont le premier signe visible d’une infestation. Contrairement aux adultes, elles sont plus difficiles à repérer en raison de leur taille minuscule. 

Taille et apparence des larves/nymphes

  • Petite taille : Environ 1 mm à l’éclosion et jusqu’à 4 mm avant leur mue vers le stade adulte.
  • Forme ovale et allongée.
  • Couleur translucide, qui devient plus foncée après leur premier repas de sang.
  • Corps mou et fragile, contrairement aux adultes qui ont une carapace plus rigide.

Différence avec d’autres insectes

Les larves de punaises de lit sont parfois confondues avec d’autres nuisibles. 

Voici quelques éléments pour ne pas se tromper :

InsectesAspect de larves
Larves de pucesTrès difficile à voir à l’oeil nu. 
Mesurent 0,5mm de long et sont blancs et ovales.
Présent sur les animaux.
AcariensLes acariens sont microscopiques et ne sont pas visibles à l’œil nu.
Larves de mitesPlus grandes, mesurent jusqu’à 12 mm et se trouvent dans les vêtements ou la nourriture.

Cycle de vie des punaises de lit : différence entre larves, nymphes et adultes

Bien comprendre les différentes étapes du cycle de vie des punaises de lit permet de réagir efficacement. Le “Cimex lectularius” passe par plusieurs stades de développement : oeufs, cinq stades immatures (nymphes) puis adulte.

1. Les oeufs de punaises de lit

  • Taille : Environ 1 mm à l’éclosion, presque invisible à l’œil nu.
  • Couleur : Blanchâtre, translucide, ce qui les rend difficiles à repérer.
  • Aspect : ressemblent à un grain de riz qui colle.

On les retrouve principalement dans les coutures des matelas, les fissures des meubles, derrière les plinthes et dans les endroits sombres.

2. Les nymphes de punaises de lit

Dès que l’œuf éclot, il devient une nymphe. On parle ici de stade de développement immature ou “stade juvénile” qui se déroule en 5 phases. C’est à partir du stade immature que la punaise de lit a besoin de se nourrir de sang pour progressivement passer à sa phase adulte. On trouve ainsi souvent des nids de punaises de lit à proximité du lieu de “nourriture”.

  • Taille : De 1,5 mm à 4 mm, grandissant progressivement après chaque repas.
  • Couleur : Plus foncée que les larves, devenant brun clair à mesure qu’elles évoluent.
  • Aspect : Ressemblent à l’adulte, avec le même nombre de pattes et la même forme.
  • Mobilité : Elles se déplacent la nuit en quête d’un hôte.

Elles muent cinq fois avant d’atteindre le stade adulte, nécessitant un repas de sang à chaque mue : 

  • 1er stade de la nymphe (1,5 mm)
  • 2ème stade de la nymphe (2 mm)
  • 3ème stade de la nymphe (2,5 mm)
  • 4ème stade de la nymphe (3 mm)
  • 5ème stade de la nymphe (4,5 mm)

3. Les punaises de lit adultes

  • Taille : Environ 5 à 7 mm, visibles à l’œil nu.
  • Couleur : Brun rougeâtre et plus foncée que les nymphes.
  • Aspect : Corps ovale et aplati lorsqu’elles sont affamées, mais pouvant gonfler après un repas.
  • Mobilité : Plus rapides que les nymphes, elles se déplacent efficacement dans toute la pièce.
  • Reproduction : Une femelle adulte pond jusqu’à 5 œufs par jour et plus de 500 dans sa vie, accélérant la prolifération en quelques semaines.

À quelle vitesse une infestation peut-elle se développer ?

Plus la température est élevée, plus les punaises se développent rapidement.

  • À 28°C, une larve devient adulte en 45 jours.
  • À 18°C, le cycle dure environ 100 jours.
  • À 13°C, il faut près de 5 mois pour atteindre le stade adulte.

Où trouve-t-on les larves de punaises de lit ?

Les larves de punaises de lit restent discrètes et cachées dans des endroits sombres et difficiles d’accès. Contrairement aux adultes, elles ne se déplacent pas loin et restent proches de leur source de nourriture principale : l’homme.

1. La literie

  • Coutures et plis des matelas : les larves aiment se loger dans les recoins des matelas et sommiers.
  • Interstices des sommiers : elles se cachent sous les lattes ou dans les fissures du bois.
  • Oreillers et draps : elles laissent parfois des traces de sang et des excréments noirs visibles sur le linge de lit.
  • Tête de lit et cadres de lit : elles trouvent refuge dans les fentes du bois ou derrière les structures rembourrées.

2. Les meubles et objets proches du lit

  • Tables de nuit et commodes : les larves s’infiltrent dans les tiroirs ou sous les meubles.
  • Canapés et fauteuils : elles se logent dans les coutures et sous les coussins.
  • Rideaux et tapis : elles apprécient les tissus épais où elles peuvent se cacher.
  • Prises électriques et fissures des murs : les larves peuvent aussi s’infiltrer dans les recoins sombres et peu accessibles.

3. Les vêtements et les bagages

  • Linge de lit et vêtements : elles peuvent s’accrocher aux tissus et se déplacer avec eux.
  • Bagages et sacs de voyage : un lieu de contamination fréquent après un séjour dans un hôtel infesté de punaises de lit.

Les autres signes d’infestation

En plus des larves, plusieurs indices peuvent confirmer la présence de punaises de lit chez vous :

  • Traces de piqûres : boutons rouges regroupés en ligne ou en grappe, souvent sur les bras, jambes et dos.
  • Taches noires sur le matelas et les draps : ce sont des excréments laissés par les punaises.
  • Présence d’exuvies : les mues transparentes des nymphes sont souvent visibles près des cachettes.
  • Odeur inhabituelle : une infestation avancée peut dégager une odeur sucrée ou de moisi.

➡️ Pour en savoir plus, vous pouvez consulter les différents niveaux d’infestations établis par l’INELP. Par ailleurs, la détection canine est très efficace pour détecter les punaises de lit.

Comment tuer les larves de punaises de lit ?

Si vous repérez des larves de punaises de lit chez vous, il faut agir immédiatement pour éviter qu’elles ne deviennent adultes et ne se reproduisent. Nous vous conseillons de combiner les méthodes suivantes :

Traitements mécaniques et préventifs

  • Passez l’aspirateur : Insistez sur les fissures des meubles, coutures de matelas, sommiers et recoins sombres. Jetez immédiatement le sac ou videz le bac dans un sac hermétique que vous déposerez dans une poubelle extérieure.
  • Lavez le linge infesté : Tous les textiles exposés (draps, vêtements, rideaux) doivent être lavés en machine à 60°C, puis passés au sèche-linge à haute température.
  • Utilisez un nettoyeur vapeur : Une vapeur sèche à 120°C tue instantanément les larves, nymphes et œufs, notamment dans les matelas, sommiers et fissures des murs. La vapeur fonctionne jusqu’à 5 cm d’éloignement, au-delà, ce n’est pas efficace.

La terre de diatomée SERENID : Ce produit naturel a une action coupante qui dessèche les larves et adultes en 4 à 5 jours. Appliquez-la dans les recoins, le long des plinthes et derrière les prises électriques.

Traitements thermiques

  • Le traitement par le froid : Placez les textiles et petits objets infestés au congélateur à -20°C pendant 72 heures minimum pour tuer les larves et les œufs.

➡️ Pour aller plus loin: Le protocole complet contre les punaises de lit.

Comment éviter une nouvelle infestation ?

La meilleure solution contre les punaises de lit reste la prévention.

Voici quelques bonnes pratiques : 

  • Évitez d’acheter des meubles d’occasion sans les désinfecter.
  • Surveillez votre literie régulièrement (coutures, sommier, matelas).
  • Placez des housses anti-punaises sur votre matelas et vos oreillers.
  • Appliquez de la terre de diatomée derrière les prises électriques, sous le lit et le long des plinthes.
  • Lors de vos voyages, rangez votre valise en hauteur.

Bed bugs and pets: what you need to know

chien qui dort

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.

  • 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
  • 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

  • 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.

  • 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 bed bug bites dangerous for pets?

However, their (rare) bites can cause various problems for dogs, cats, birds and other pets:

  • Irritation and itching
  • Allergic reactions
  • Stress and behavioural disorders
  • Mild anaemia in fragile animals

How can you relieve bed bug bites on your pet?

To soothe itching and prevent infection in your pet, here are the steps to take:

1. Clean your pet’s skin and coat.

  • Gently wash the affected area with lukewarm water and mild soap suitable for animals.
  • Dry the skin thoroughly to avoid maceration, especially in long-haired animals.

2. Apply a soothing treatment

  • Use a specific soothing lotion for animals (based on aloe vera, calendula or camomile).
  • You can also apply a cold water compress to relieve irritation.

3. Prevent your pet from scratching too much

.

  • Trim your pet’s claws to limit injuries caused by scratching.
  • For cats and dogs, a collar or a collar may be useful if licking is excessive.
  • Consult a vet if necessary!

Are chemical bed bug treatments dangerous for pets?

Paris, France, le 27 septembre 2023. Philippe désinfecte un appartement de ses punaises de lit. photo : LP / Olivier Corsan

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

Détection canine
Détection canine

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.

Bed bug marks and spots: recognising them and the treatments to be applied

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.

➡️ To find out more: The complete bed bugs protocol.

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.

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

➡️ See also: How can you relieve bed bug bites?

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.

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.

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.

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

Bed bugs in Airbnb: solutions for travellers and hosts

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.


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.

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.

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.
