Holiday Lets and Airbnb: The Anti-Pest Protocol to Apply Between Two Guests

The call almost always comes after the review. Not after a bite, not after a sighting: after the words written in public, the ones that stay online and that the next fifteen travellers will read before booking. "We found bed bugs." The owner calls within the hour, wants an intervention the next day, wants a certificate, and above all wants to understand how it happened when the property is cleaned between every single stay.

The answer comes down to one simple figure: a furnished holiday rental changes occupants between 30 and 80 times a year, whereas a conventional home sees one new occupant every three years. Every arrival means luggage transported from another property, another hotel, another train. The end-of-stay clean, meanwhile, rarely lasts more than two to three hours and is designed for visible cleanliness — not for entomological detection.

A bed bug brought in inside a suitcase can remain undetectable for four to eight weeks, the time it takes for the population to grow from a few individuals into a visible colony. In a short-term rental, that means the infestation is already established by the time the first traveller complains — and that three to ten stays have taken place between introduction and report.

This article sets out the inspection protocol to slot into the changeover clean between two guests, the areas genuinely worth checking, the equipment that saves time, and the legal framework applicable to furnished-rental hosts in France.

Why short-term rentals concentrate the risks

This isn't about dirt. The furnished holiday rentals we treat are often better maintained than a family flat. The problem is structural.

Three species dominate short-term rental cases, and they don't come in through the same door.

• The bed bug (Cimex lectularius) arrives in luggage, backpacks, sometimes clothing. It is risk number one in terms of frequency and reputational cost.
• The German cockroach (Blattella germanica) arrives with the shopping, delivery boxes, and the building's service ducts — and thrives during vacancy periods when crumbs and damp stay put.
• Clothes moths and pantry moths take advantage of closed cupboards and the half-empty packets left behind by travellers: a bit of leftover rice, flour or pet food forgotten for three weeks is enough.

To this you can add, in autumn, rodents moving into sparsely occupied properties, and wasps looking to overwinter behind the shutters of a studio flat that has been closed since September.

The ten-minute check: what you really need to look at

A thorough changeover clean doesn't need to turn into a professional inspection. It needs ten structured minutes, always in the same order, always in the same places. Bed bugs are found within a 1.5 m radius of the resting place: there's no point rummaging through the kitchen.

1. The mattress, starting with the seams

Remove the protector and fitted sheet completely. Follow the piped seams of the mattress on all four sides, then the labels and the side handles. You're looking for:

• black pinpoint stains 0.5 to 1 mm across (droppings, which smear if you dampen them);
• small dried blood marks on the fabric;
• translucent, amber-coloured shed skins that look like the insect but are hollow;
• pearly white eggs 1 mm long, stuck in clusters inside a fold.

A UV black-light torch makes organic deposits stand out on light-coloured fabric and speeds this stage up — with one limitation to keep in mind: it also reveals plenty of false positives (detergent residue, fluorescent fibres). It's there to narrow things down, not to conclude.

2. The bed base and frame

This is where most established colonies are found, far more than in the mattress. Points to check:

• the inside of the fabric on an upholstered divan base (lift the bed, look from underneath);
• screw corners and metal brackets;
• the headboard, particularly if it is padded or wall-mounted — pull it away by a centimetre to inspect the back;
• the legs, and the undersides of the castors.

3. Seating and nearby textiles

Sofa bed, bedroom armchair, decorative throw, curtains whose hems touch the floor less than a metre from the bed. The living-room sofa bed is the second most common harbourage in studios and one-bedroom flats let on a short-term basis.

4. The blind spots

• Skirting boards behind the bed and around electrical sockets.
• Lifting wallpaper, picture frames hung above the bed, the bedroom's ventilation outlet.
• The bedside table drawer, removed completely, runners included.
• Luggage items left in place: luggage rack, fabric laundry basket.

Field rule: a single sign isn't enough to declare an infestation, but a single sign is enough to suspend bookings while a diagnosis is carried out. It costs far less than a public review and a refund.

Setting up the property so it can be checked quickly

A well-designed rental can be checked in ten minutes; a poorly designed one takes an hour. A few equipment choices radically change the workload.

Encase the bed. A full bed-bug-proof mattress encasement and base cover, with a locking zip, serve two purposes: they stop insects reaching the internal seams, and they provide a smooth, light surface where any black stain shows up immediately. It's the best efficiency-to-price investment for a short-term rental. Choose one certified for bed bugs (mesh under 0.2 mm) rather than a simple waterproof mattress protector.

Remove the hiding places. A bed on metal legs rather than a storage ottoman base, a headboard in solid wood or metal rather than padded, no carpet in the bedroom, sealed skirting boards. Every hiding place removed is inspection time saved at every changeover.

Standardise the linen. White or very light protectors and sheets, washable at 60 °C. Official sources, including the reference guidance from the French housing ministry on bed bugs, point out that a 60 °C wash for 30 minutes or a tumble dry at high temperature destroys all life stages, eggs included. Dark fabric makes visual inspection impossible.

Provide a luggage drop point. A metal luggage rack by the entrance, well away from the bed, plus a written note in the welcome book, mechanically reduce the risk of import. The instruction works better when framed as a service ("for your comfort, a luggage rack is available") than as a health warning.

Equip the vacuum cleaner properly. A vacuum cleaner with HEPA filtration and a crevice tool lets you vacuum bed-base grooves and skirting boards without redispersing debris. The bag or canister must be emptied into a sealed bag, outside the property, immediately afterwards.

Passive detection between stays: the tools that work for you

Visual checking depends on whoever does the cleaning and how much time they have. Passive detection, by contrast, runs continuously.

Bed-leg interceptors — those double-walled cups placed under each leg — are the most cost-effective tool in a furnished rental. They trap bed bugs climbing towards the sleeper or coming back down, and a five-second check at every clean provides dated information. For this to work, the bed must be pulled a few centimetres away from the wall and no textile may touch the floor.

Pheromone sticky traps for cockroaches placed behind the fridge, under the sink and in the dishwasher housing give the same kind of early warning on the kitchen side. Three traps checked once a month are enough to know whether the property is under pressure from the building's service ducts.

Off-season: the vacancy trap

From November to March, many furnished holiday rentals tick over at a slow pace. That's the period when we see the most undetected damage.

• Rodents. An empty studio, heated to a bare minimum, with cupboards containing pasta, rice and sugar, is an ideal larder. Transferring all dry goods into airtight glass storage containers or rigid plastic removes the resource. A packet of pasta in its cardboard box won't survive three days against a mouse.
• Dry traps. A trap that dries out opens a direct route from the drainage stacks: cockroaches and odours. Run the water at every outlet on each visit, or pour a little cooking oil into the traps of properties closed for several months.
• Stored textiles. Blankets and throws stored at the back of a cupboard without checking: perfect ground for moths. Store them in closed garment bags, with a cedar- or lavender-based repellent, and take them out on the first day of reopening.
• Wasps and hornets. Check roller-shutter boxes and loft spaces before reopening in spring. A nest built in April in a closed property is discovered in June by a traveller.

A twenty-minute monthly visit off-season costs infinitely less than putting things right in April.

What the legal framework says for the host

Furnished holiday letting is not exempt from a landlord's obligations. Two pieces of legislation shape the situation in France.

• The Act of 6 July 1989 (article 6) requires the delivery of a property "free from any infestation of pest and parasitic species". Introduced by the 2018 ELAN Act, this wording makes bed bugs grounds for non-compliance of the property.
• The Decree of 30 January 2002 on decent housing, and, for furnished holiday rentals, the departmental health regulations (règlement sanitaire départemental), complete the framework. Where a nuisance affects public health, the mayor may intervene under the Public Health Code.

On top of this comes contractual liability towards the traveller: an infested property does not match the listing, which gives rise to a right to a refund and, depending on the platform, to rehousing at the host's expense. Since 2024, bed bug action has been centralised by the public authorities through a national information service; the pages of the French housing ministry and of Santé publique France point out that bed bugs do not transmit disease but do cause skin reactions and a real psychological impact — something confirmed by the Vidal and Ameli factsheets on bed bug bites.

On the treatment side, ANSES regularly warns about the risks of non-compliant biocide use by private individuals: foggers, "total release" aerosols and improvised mixtures scatter the insects into neighbouring flats without treating the harbourage. In a block of flats, that's the surest way to turn a studio problem into a building-wide problem.

The protocol in practice: an end-of-stay checklist

To stick inside the utility cupboard or add to the cleaning contractor's job sheet.

1. Strip all the bed linen and put it straight into a sealed bag before taking it to the machine (never shake it out or lay it on an armchair).
2. Wash at 60 °C for 30 min, or tumble dry hot for 30 min if the fabric can't take 60 °C.
3. Inspect the bed-bug encasement on the mattress and base: stains, tears, zip fully closed.
4. Check the interceptors under all four bed legs. Record the date, even when the result is negative.
5. Inspect mattress seams, the back of the headboard, the bedside drawer, the sofa bed.
6. Vacuum skirting boards, bed-base grooves and the undersides of furniture with the crevice tool; empty the bag outside.
7. Completely clear the food cupboards of anything left by travellers. Nothing carries over from one stay to the next apart from sealed products.
8. Run every water outlet, check that no trap has dried out.
9. Check the kitchen cockroach traps (once a month).
10. If there's any sign: block the calendar and call a Certibiocide-certified professional before any new arrival.

Ten points, ten minutes when the property is properly equipped. It's the only way to avoid discovering an infestation through a public review.

If the suspicion is confirmed

Don't attempt a DIY treatment in a property due to be re-let within 48 hours. Three reasons:

• an incomplete treatment moves the infestation without eliminating it, and you re-let a property that is still infested;
• you'll have no documentation to rely on in a dispute with a traveller or the platform;
• poorly applied consumer products create documented resistance in Cimex lectularius.

The right move is a professional diagnosis, a treatment in two visits 14 to 21 days apart — dry steam above 120 °C, targeted contact treatment, or even whole-room heat treatment — then a confirmation check before returning the property to the market. Allow three weeks of blocked calendar for a studio. That's a long time; it's always shorter than rebuilding a reputation.

A furnished holiday rental can't avoid introductions: that's the nature of the business. What it can do is detect them in week 1 rather than week 8. That's where the entire difference in cost lies.
