7 Tricks To Avoid Mosquito Bites

Expat Tips Published: 11 June 2019 10:58 CET Updated: 14 April 2026 10:58 CET

If you live in or visit Spain during the warmer months, mosquito bites can quickly turn a good evening into an itchy disaster. They are at their worst when you are trying to eat outside, sleep with the window open, or enjoy time on a terrace near gardens, rivers or humid areas.

The good news is that avoiding mosquito bites is usually more about habits than luck. A few practical changes can make a big difference, especially if you are consistent with them.

Why Mosquitoes Are Such A Nuisance In Spain

Mosquitoes are a common problem in many parts of Spain during the warmer part of the year, particularly near still water, irrigated land, gardens, wetlands and coastal areas. Most bites are simply irritating, but they can still ruin sleep, trigger swelling, and make outdoor evenings miserable. In some parts of Europe, mosquito-borne illnesses such as West Nile virus are also monitored by public-health authorities, which is another reason not to treat mosquito prevention as a joke.

1. Wear Clothing That Gives You Some Protection

Mosquitoes cannot bite through every fabric equally, so one of the simplest ways to protect yourself is to cover more skin. Long sleeves, light trousers, ankle-covering socks and looser fabrics can all help reduce exposed areas.

This does not mean you need to dress like you are trekking through a jungle every time you go for dinner. It simply means that if you know mosquitoes are bad in your area, a floaty long-sleeved shirt and lightweight trousers will usually serve you better than shorts and a vest.

2. Use A Proper Insect Repellent

This is the big one. If mosquitoes are already active where you live or where you are staying, a proven insect repellent is usually the most effective everyday defence.

Look for repellents with active ingredients such as:

DEET
picaridin
IR3535
oil of lemon eucalyptus / PMD
2-undecanone

Apply it properly to exposed skin and reapply it as directed on the label. If you are also using sunscreen, apply the sunscreen first and the repellent afterwards.

3. Make Your Bedroom Harder For Mosquitoes To Reach

A lot of bites happen at night, especially when people leave windows open and assume mosquitoes will politely stay outside. They will not.

Simple changes can help a lot:

sleep with windows screened if possible
use mosquito nets where needed
use air conditioning if you have it
keep doors and windows closed at dusk if mosquitoes are bad locally

If you are staying somewhere rustic, especially in the countryside, checking the bedroom before sleep is not paranoia. It is just experience.

4. Treat Clothing And Gear If You Need Stronger Protection

If you spend a lot of time outdoors in areas with heavy mosquito activity, ordinary repellent on skin may not be enough on its own. In those cases, treated clothing can give you an extra layer of protection.

Permethrin can be used on clothing and gear such as socks, trousers, boots and camping equipment. It should not be applied directly to skin, but it can be very useful for people walking, gardening, camping or spending time outdoors in mosquito-prone areas.

5. Be Smarter About The Times And Places You Sit Outside

You do not need to hide indoors all summer, but you do need to use your head a bit. Mosquitoes are often more active around dusk and in areas with standing water, dense planting, irrigation or poor airflow.

If you always get bitten while sitting outside in the same corner of a terrace or garden, there is usually a reason. Sometimes moving to a breezier spot, sitting away from damp planting, or avoiding peak mosquito time for an hour or two makes more difference than people expect.

6. Get Rid Of Standing Water Around Your Home

If you have a garden, terrace or patio, mosquito prevention is not only about protecting your skin. It is also about making your home less attractive to them in the first place.

Check regularly for places where water sits still, such as:

plant saucers
buckets
watering cans
blocked drains or gutters
pet bowls left outside too long
unused containers on balconies or patios

Small amounts of water are enough for mosquitoes to breed, so this is one of those annoying little jobs that actually matters.

7. Protect Babies And Children Properly

Children are often bitten more than adults simply because they are outside more, move around more, and are less likely to leave a bite alone once it starts itching.

Good habits include:

dressing children in clothes that cover arms and legs where practical
using mosquito netting over prams and baby carriers
following repellent instructions carefully
not applying repellent to children’s hands, eyes, mouth, cuts or irritated skin
avoiding products containing OLE or PMD for children under 3

For babies younger than 2 months, repellents are not the first answer. Physical protection such as netting and clothing matters more.

What To Do If You Get Bitten

Even if you do everything right, you will still get bitten from time to time. When that happens, the aim is to calm the skin and avoid making it worse.

Helpful basics include:

washing the area gently
using a cool compress
applying an appropriate anti-itch product from the pharmacy if needed
trying not to scratch, especially in hot weather

If the bite becomes unusually swollen, looks infected, or is accompanied by fever or other symptoms, it is worth speaking to a pharmacist or doctor rather than just scratching your way through it and hoping for the best.

Final Thoughts

The best mosquito strategy is usually not one miracle product. It is a combination of sensible clothing, proper repellent, better sleeping conditions, fewer breeding spots and slightly smarter outdoor habits.

Do those things consistently and you will usually cut the problem down sharply. Ignore them and the mosquitoes will continue treating you like an open buffet.
