There’s a specific kind of Google phenomena that happens before a holiday. Your flights are already booked, accommodation is already arranged, and then at eleven o’clock at night you find yourself typing “are there cockroaches in Tenerife” hoping it’s all clear.
Don’t Panic, Of Course There’s Bugs.
Tenerife is just off the coast of Africa and the climate is very mild year round. The whole place is essentially a giant warm greenhouse with a beach attached. Bugs exist here. That’s not a scandal, it’s just geography.
What I can tell you, from actual time spent here rather than from a brochure, is that the bug situation is genuinely mild compared to almost anywhere else you’d go for winter sun. I’ve eaten outside in Los Cristianos on warm July evenings, food going cold because I was too busy talking, and not been bothered once. Coming from the UK, where a summer barbecue is basically a wasp negotiation, that still catches me off guard every time.
I’ve seen cockroaches on the street in the south of the island moving with that horrible confident speed they have, like they own the place and for some reason love running straight at you. We call them confrontational roaches.
Mosquitoes: Where They Are On The Island
The south of is very dry and dusty which is not the typical environment mosquitoes like. With almost constant sea breeze, it’s not a comfortable environment for mosquitoes to breed. They need the air to be still and have pools of water where they can breed and the south doesn’t offer much of that.
In most parts of the south, you could sit outside every evening for two weeks and never get bitten. Most people don’t.
The north is completely different. It’s greener, cooler, the food is better, the whole thing feels more like an actual place rather than a resort set. But it’s also wetter. The air is heavier. After rain, which happens more than people expect up there, you’ll notice more insects. If there’s been some rain and water has collected in some areas, the chances are that if you leave your windows open at night, you might wake up with a couple of bites.
The higher the elevation on the island, the less chance of experiencing them. Up around Teide there’s basically nothing. Most critters dislike that open and exposed environment where they can’t hide.
The Tiger Mosquito Thing: Don’t Panic, But Do Know About It
At some point during your research you’ll hit something about tiger mosquitoes and your stomach will drop a little. I want to deal with this properly because most articles either exaggerate, or wave it away.
The tiger mosquito, Aedes albopictus, is found dotted around the island and is smaller than a regular mosquito and is slightly darker with white stripes on its legs. It’s very stealthy and rarely heard and that’s what catches people out. You don’t hear it coming, and it bites during the day rather than at dusk. I find their bite a bit more intense than a regular mozzie.
Here’s what actually matters though. In other parts of the world, this mosquito is responsible for carrying things like Zika and Dengue among others but the ones in the Canaries do not carry these diseases so there is no need to to be concerned. The Canary Islands health authorities maintain constant surveillance all year round to make sure there are no instances of disease being spread by mosquitoes and international bodies have also given the islands a green light.
Use repellent if you’re spending time near the port areas of Santa Cruz. Don’t lose sleep over it anywhere else.
Cockroaches: The Thing Most Travel Articles Quietly Skip
Right. This is the one people don’t warn you about, and I think that’s genuinely unhelpful.
Yes you’ll find cockroaches on the island but it’s nothing to be too concerned about.
The most common ones are the large American cockroach, or “sewer cockroach”. The drains and gutters can be active at night and is not a sign of filth because even when clean, they’ll still be there.
There are routine sewer fumigation procedures on the island where they’re known to be active and are kept under control. Sometimes the fumigation can cause them to break out of their hiding places in drains and crevices which is only a good thing to purge the location of them.
The ones indoors are usually the smaller German cockroach. Apartments that sit empty usually fall victim to cockroaches so it’s a good idea to consider this if you own a property rental that is left vacant often.
Modern hotels and well-managed complexes run regular pest control programmes and you’re unlikely to see one inside. But in an older rental, a rural finca, or a budget apartment in a building that hasn’t been properly maintained, they’re a real possibility. Worth knowing before you book rather than after you arrive and find one in the kitchen at midnight.
I Learned This the Hard Way in Garachico
I once visited Garachico which is a nice little town with black volcanic natural rock pools. I went to a local bar on the plaza where the coffee was strong and the tostada came with proper tomato.
It had rained for several days prior to me arriving there and enough to allow water to settle in little pools which is perfect for mosquito breeding. By the end of my visit I had several mosquito bites and a repellent spray that was mostly unused.
Tenerife has a reputation for being dry and arid because many only ever experience the south. The north on the other hand is quite different with its green and lush environment.
It’s always a good idea to keep some insect repellent handy just in case.
Does Tenerife Have Any Other Bugs?
Wasps: There are hardly any. You can leave a glass of fizzy drink on an outdoor table for an hour and nothing will happen. For anyone who’s spent a British summer defending their lunch, this alone is worth the flight.
Ants: Yes, and they’re fast. Leave food out on a terrace and they’ll find it within twenty minutes. Tiny, harmless, completely relentless.
Flies: A few, around fish markets and busy restaurant terraces. Nothing excessive.
Moths and large beetles: They love bright lights and often collide with people who get in the way.
Centipedes: Occasionally found in rural properties and older buildings, particularly in the north and have a painful bite if you step on one barefoot but they are not very common unless you go looking for them.
Spiders: There are a few species on the island but none of them pose any risks. Banana plantations tend to attract them.
No hornets. No aggressive biting flies. No clouds of midges. The absence of wasps in particular is something I still notice every single time I land.
The Time of Year And Its Impact?
For mosquitoes, less than you’d think. Because Tenerife’s temperatures don’t swing dramatically between seasons, there’s no real mosquito season the way there is back home. What makes a difference is rain. Mosquitoes breed in standing water and their lifecycle is roughly ten to fifteen days, so a wet spell in the north can produce a noticeable increase for a couple of weeks afterwards.
For cockroaches, the warmer months from May to October are when activity peaks, though on Tenerife there’s honestly no real off season for them. The island’s year-round warmth means they stay active even in winter, which is different from mainland Spain where they slow down in the cold.
Up around Teide and at higher altitudes, insects of all kinds are far less of an issue. Too cold, too exposed. If you’re spending time in the national park, bugs are genuinely the last thing on your mind.
What to Actually Pack
A small bottle of DEET-based repellent. That’s it for mosquitoes. You can also buy it at any farmacia on the island if you forget, they’re easy to find and not expensive.
For cockroaches, the main thing is awareness rather than panic. If you’re renting an apartment, check the bedroom windows have screens. Run the taps when you arrive if the place has been empty. Don’t leave food out overnight, especially on outdoor terraces. Keep bin lids closed. Small things, but they make a real difference.
If cockroaches are a genuine concern for you, look for newer builds or well reviewed hotels with active pest control programmes. Older apartments in busy resort areas, particularly ones with shared plumbing and a high turnover of guests, are where you’re most likely to have an issue.
The Questions People Are Actually Googling
Are there mosquitoes in Tenerife in winter? Very few. December through February is the quietest time. Most people visiting in winter don’t get bitten at all, especially in the south.
Are cockroaches common in Tenerife hotels? In modern, well-managed hotels, rarely. In older apartment complexes or budget rentals, more possible. Check recent reviews specifically mentioning cleanliness before you book.
Do I need malaria tablets for Tenerife? No. There’s no malaria risk anywhere in the Canary Islands. No special vaccinations needed either.
Are cockroaches in Tenerife dangerous? They can carry bacteria including Salmonella, and their droppings are a known trigger for asthma and allergies. They won’t bite you unprovoked, but you don’t want them in your kitchen. Keep food sealed and drains covered.
Is the south better than the north for avoiding bugs? Yes, noticeably. Drier, less green, almost always breezy. Fewer mosquitoes and, in well-maintained resort areas, fewer cockroaches too.
What about sand flies on Tenerife beaches? On the main tourist beaches, not really. In quieter, more sheltered coves at dusk in summer, occasionally. Repellent sorts it.
Are there dangerous spiders or scorpions in Tenerife? Nothing that poses any real risk to tourists. Scorpions are extremely rare. Most visitors never see one.
One Last Thing
Tenerife isn’t a buggy island. That’s genuinely true, and it’s one of the things I appreciate most about it. But it’s not bug-free either, and pretending otherwise doesn’t help anyone.
The cockroaches are the thing most travel articles quietly ignore, and I think that’s a disservice to people trying to plan a good trip. Knowing they exist, knowing where they’re most likely to show up, and knowing what to do about it means you’re not caught off guard at midnight in an older apartment wondering if something’s wrong with the place.
Pack some repellent, check your window screens, run the taps when you arrive somewhere that’s been empty, and then stop thinking about it. The island has far better things to offer than this particular worry, and most people come back without a single significant encounter.
You’ll be fine. And if you do get one mosquito bite the whole trip, honestly, that’s still a very good holiday by any measure.
