Pests in Tourist Accommodation: How to Prevent Them, What to Do if They Appear, and How Much They Cost

A one-star review saying "there were cockroaches in the kitchen" can sink your listing for months. And if they are bed bugs, it's directly a crisis: floor blockage, expensive treatment, angry guests demanding refunds, and devastating reviews. Pests are the silent problem of tourist rentals: no one talks about them until they appear. In this post, I tell you how to prevent them, what to do if it happens, the cost of each treatment, and how to manage the crisis with guests.

Why tourist accommodations are magnets for pests

A tourist apartment has three factors that attract bugs like few other accommodations:

• Constant turnover of people: each guest can unknowingly bring pests (especially bed bugs in luggage).
• Food leftovers: people on vacation cook little, leave crumbs, don't take out the trash before leaving, forget fruit in the pantry.
• Empty periods: between bookings, if no one steps into the apartment for weeks, pests settle in quietly.

If your apartment is on the ground floor, has a garden, an interior patio, or is near a restaurant, multiply the risk.

The most common pests in tourist accommodation

Cockroaches

The most frequent. Mainly appear in kitchens, bathrooms, and pipes. A single cockroach in a review can drop your rating by half a point.

Signs: droppings (look like ground pepper), rancid smell, dead cockroaches in corners.

Bed bugs (the worst-case scenario)

They are the absolute nightmare of tourist rentals. They travel in suitcases, clothes, and furniture. It's nothing to do with cleanliness: even 5-star hotels suffer from them.

Signs: bites in straight lines on the guest's skin, black spots on mattress seams, small blood stains on sheets.

Ants

In spring and summer, especially if there is a garden or terrace. Less serious but annoying.

Mice and rats

More common in ground-floor apartments, rural houses, or areas with nearby construction.

Mosquitoes

In coastal areas, humid places, or near stagnant water. In summer, almost unavoidable without mosquito nets.

Wardrobe and pantry moths

Appear if the apartment has been closed for weeks with clothes or food stored.

Actual costs of each pest (with numbers)

Pest	Professional treatment	Days to block the apartment	Risk of negative review
Cockroaches	80-150 euros	1-2	High
Bed bugs	300-800 euros	5-14	Very high
Ants	60-100 euros	0-1	Medium
Mice/rats	150-300 euros	2-5	High
Moths	50-100 euros	0-1	Low
Mosquitoes	80-150 euros (fumigation)	0-1	Medium

And these are only direct costs. Add:

• Refund to affected guest: between 200 and 1,500 euros depending on duration.
• Subsequent cancellations due to negative review: you can lose thousands of euros in future reservations.
• Replacement of mattresses, sofas, or textiles (in case of bed bugs): easily 500-2,000 euros.

A poorly managed bed bug infestation can cost you between 2,000 and 5,000 euros in treatment, refunds, replacements, and lost bookings. Investing in prevention is worth it.

Prevention: what you can do before they appear

During each guest turnover

• Vacuum mattresses, room corners, and under furniture thoroughly.
• Check mattress and sofa seams for black spots (bed bugs).
• Empty trash bins and take out the bag outside the apartment.
• Ensure no open food remains in the pantry.
• Clean the extractor hood, stove, and behind appliances every 2-3 months.

Installations that help

• Mosquito nets on all operable windows. Cost: 50-120 euros per window. Recovers in one season.
• Anti-pest grilles on drains and sinks. 5-15 euros each.
• Seal cracks in skirting boards, walls, and door frames. Cheap silicone, high impact.
• Preventive cockroach traps in kitchen and bathroom (gel bait). 10-20 euros, last for months.

Periodic preventive treatments

In high-risk areas (coast, ground floor, near bars), hiring a pest control company 1-2 times a year is cost-effective. Cost: 100-200 euros per visit. They provide certification and prevent 80% of problems.

Communicate with the cleaning company

Ensure your cleaning team knows what to look for and alerts you at the first sign. A good cleaning protocol includes pest checks. It is the first line of defense.

What to do if a guest reports a pest

This is the critical moment. How you respond in the first 30 minutes determines whether you get a 5-star or 1-star review.

Step 1: Respond quickly and empathetically

Never minimize. Never say "it's impossible, it never happens here". Believe the guest. Ask for photos if possible.

Step 2: Offer immediate solution

Depending on severity:

• Minor pest (1-2 ants, one mosquito): send someone with insecticide within 2 hours.
• Moderate pest (cockroaches, more ants): in addition to treatment, offer compensation (discount, dinner, bottle of wine).
• Severe pest (bed bugs, mice, widespread cockroaches): relocate the guest to another accommodation at your expense and refund the stay.

Step 3: Contact a professional

Do not try to treat bed bugs or mice yourself. Supermarket products don't work and only prolong the problem.

Step 4: Block the calendar

Until treatment is complete and verified, do not accept new bookings. Accepting bookings with ongoing pest issues will make the problem snowball.

Step 5: Manage the review

If the guest leaves a negative review, respond calmly, acknowledge the problem, and explain what you did. More on managing negative reviews.

Bed bugs: special protocol

Bed bugs deserve a separate section because they are the most severe scenario.

How to detect them

• Black dots on mattress seams, headboard, bed frame.
• Small blood stains on sheets.
• Guest reports bites in straight lines (3-4 points), especially on arms, legs, or back.
• Translucent brown shells (bed bug moltings).

What to do immediately

1. Relocate the guest. No negotiation here. Move to another accommodation and refund the difference.
2. Close the apartment for at least 2 weeks. No shortcuts.
3. Hire a specialized bed bug company. Not a general pest control company: one specialized, using heat or steam above 60 degrees.
4. Prepare for 2-3 treatments. Bed bugs are tough. One treatment rarely suffices.
5. You may need to discard mattresses, sofas, or textiles. Be prepared.

How to prevent them

• Anti-bed bug covers on all mattresses. 30-60 euros per mattress. The best pest prevention investment.
• Vacuum seams after each guest change.
• Visually inspect the mattress when making the bed.
• Wash sheets at 60 degrees minimum.

Legal aspects: can you be fined?

In Spain, pests in tourist accommodations fall under public health jurisdiction. If a guest reports and an inspection yields a positive result, you may face:

• Autonomous community sanctions: between 300 and 30,000 euros depending on the region and severity.
• Suspension of the tourist license in serious or repeat cases.
• Civil claims from the guest for damages (bites, contaminated clothing, etc.).

Each autonomous community has its regulations, but all require maintaining the accommodation in proper hygienic-sanitary conditions. You can consult the requirements by autonomous community.

Always keep certificates of pest treatments performed. If there is an inspection or claim, demonstrating that you acted quickly and with professionals protects you.

Insurance: does it cover pests?

It depends. Most tourist housing insurance policies do NOT cover:

• Pests due to lack of maintenance.
• Treatment costs.
• Loss of income due to apartment blockage.

Some specific rental insurance policies do cover related damages (e.g., mattresses to replace due to bed bugs). Review your policy. More info at what insurance you need for your tourist rental.

Basic pest control kit to always keep at home

You can keep this in a closed cabinet, ready to act:

• Generic spray insecticide (cockroaches, ants).
• Gel bait for cockroaches.
• Sticky traps for mice.
• Plug-in mosquito repellent.
• Large hermetic bags (for suspicious textiles).
• Disposable gloves.
• Contact info of a 24-hour pest control company saved in your phone.

Total cost: less than 50 euros. And it saves you from initial panic.

How Autoregistro fits in

Pests are crises that force you to act quickly, block the apartment, and communicate with guests. The last thing you need is to deal with the paperwork of the Travelers Registry in SES Hospedajes.

Autoregistro handles that for you: the guest fills out a form, their data are sent automatically to SES Hospedajes. It costs 1 euro per month per property (less than a coffee), and relieves you of one worry so you can focus on what matters, like managing the many issues that arise in a tourist rental.

Frequently Asked Questions

Should I notify future guests if I've had a pest?

You are not legally obliged if the pest has been treated and eradicated. But you must ensure the problem is 100% resolved before accepting new reservations. Accepting guests with an active pest problem can cost you your license.

Can I charge the guest if I suspect they brought bed bugs?

It's very difficult to prove legally and I don't recommend it. Platforms like Airbnb or Booking almost always side with the guest in these cases. Better to invest in prevention (anti-bed bug covers, regular inspections) than legal battles.

How often should I do preventive treatments?

In low-risk areas, once a year is enough. In high-risk zones (coast, ground floor, near hospitality), every 6 months. Annual cost: 200-400 euros. Worth it.

Do supermarket products work for cockroaches?

For one or two occasional cockroaches, yes. For an infestation, no. If you see cockroaches during the day or find more than 2-3 in a week, call professionals. Homemade treatments only disperse the pest further.

What if a guest threatens to leave a 1-star review due to pests?

Act quickly: resolve the issue, offer proportional compensation (partial or full refund depending on severity), and be honest. Many guests withdraw or soften their review if they feel you've done everything possible. If they still leave a negative review, respond publicly calmly explaining what you did. Future guests highly value good crisis management.
