7 Tricks To Avoid Mosquito Bites

If you're living in or visiting Spain, you’ve probably encountered the relentless itch of mosquito bites — especially during the warmer months. Whether you're out hiking, enjoying a terrace dinner, or just trying to sleep at night, mosquitoes can ruin the moment fast. The good news? There are easy and effective ways to protect yourself. In this updated guide, we reveal 9 simple tricks to keep these biting pests at bay — so you can enjoy the Spanish sun without the scratching.

For many expats and tourists, mosquito bites are an unfortunate part of life in Spain, especially from April through October. While most bites are just irritating, mosquitoes in some regions may carry diseases like West Nile virus. Fortunately, preventing bites is simple once you know what attracts mosquitoes and how to avoid them.

1. Wear Light-Coloured Clothing

Mosquitoes are naturally drawn to dark colours like black, navy, and charcoal grey. These colours absorb heat and offer visual contrast during low light, making it easier for mosquitoes to lock onto you. To reduce your visibility to them, opt for white, beige, or light pastel colours — especially when walking in wooded or marshy areas. Loose-fitting clothing made of breathable cotton or linen will keep you cool while providing a physical barrier to bites.

2. Apply a Reliable Insect Repellent

DEET-based repellents are still considered the gold standard, but alternatives like picaridin, IR3535, and lemon eucalyptus oil are popular and often less irritating to sensitive skin. Always apply repellent to exposed skin and clothing before leaving home, and reapply after sweating or swimming. For evenings on a terrace or at the beach, consider repellent bracelets or clip-on diffusers for added protection.

3. Avoid Peak Mosquito Hours

Mosquitoes are most active during dawn and dusk — prime hours for outdoor cafés and sunset walks. Plan your errands, runs, or hikes earlier in the day or after dark when mosquito activity dies down. If you're staying in rural areas of Spain or camping near water, be extra cautious and wear repellent at all times during these periods.

4. Cover Up Exposed Skin

In warm climates, it's tempting to wear sleeveless shirts and shorts. But every inch of exposed skin is an open invitation for mosquitoes. Choose light, long-sleeved shirts, linen trousers, and closed shoes where possible. If you’re gardening or hiking in shady or damp terrain, tuck your trousers into your socks for full leg protection — mosquitoes often hover low to the ground.

5. Sleep Under a Mosquito Net

If you're travelling or living in mosquito-prone areas — especially in southern Spain or rural inland provinces — invest in a treated mosquito net. These nets are designed to keep even the smallest insects out. If staying in hotels, ask ahead if mosquito nets are provided. For homes without window screens, consider hanging nets over beds or sleeping with windows closed and a fan on.

6. Use a Fan or Air Conditioning

Wind is a mosquito's enemy. These fragile insects can't navigate moving air efficiently, which is why they retreat during breezy days. Indoors, fans create air currents that push mosquitoes away and disrupt their flight paths. Position a fan at bed height to sweep across your body. Air conditioning also lowers your body temperature, making you less attractive to mosquitoes that hunt warm-blooded prey.

7. Eliminate Standing Water

Mosquitoes lay eggs in stagnant water — and even a tiny amount can host hundreds of larvae. Tip out flowerpot trays, buckets, ashtrays, and pet bowls at least every two days. Clean roof gutters regularly and check for puddles after rain. Mosquitoes can breed in as little as a bottle cap of water, so vigilance in your patio or garden can dramatically reduce local populations.

8. Use Natural Mosquito Deterrents

Essential oils like citronella, lavender, peppermint, and tea tree oil can help deter mosquitoes when used in diffusers, candles, or diluted sprays. Consider planting mosquito-repelling herbs like basil, rosemary, and lemongrass around balconies or terraces. While natural solutions aren't foolproof, they can supplement your protection and add a pleasant aroma to your space.

9. Protect Babies and Children

Young children have softer skin and are often bitten more frequently. Always use nets over prams, cots, and playpens. If using repellent, choose formulas specifically labelled for children and avoid applying near the hands, mouth, or eyes. For toddlers, dress them in long sleeves and leggings when outdoors and avoid dusk outings where possible.

Bonus Tip: Check Local Risk Zones

Some areas of Spain — such as wetlands in the south or rice-growing regions near Valencia — are known mosquito hotspots. Local authorities often publish updates on mosquito control measures and seasonal risks. Check local council websites or speak with neighbours to get a sense of when and where to be most careful.

What To Do If You Get Bitten

If you're bitten, wash the area with soap and water to remove any lingering saliva. Apply ice to reduce swelling, and use antihistamine creams or gels to calm itching. Aloe vera, hydrocortisone, or a dab of vinegar may also help. Avoid scratching — breaking the skin increases the chance of infection, especially in hot weather. For severe reactions or swelling near the eyes or throat, seek medical attention promptly.

Final Tips for Long-Term Prevention

Make mosquito-proofing part of your everyday routine in Spain. Keep windows shut at night or install fine mesh screens. Shake out towels and clothing before use if they’ve been left outside. If you’re frequently bitten at home, consider using plug-in mosquito diffusers or ultrasonic repellents. For those in the countryside, citronella torches and mosquito coils can help create a bite-free zone around outdoor seating areas.

If bites are frequent despite all efforts, speak with a local pharmacist or doctor. They may recommend a preventive antihistamine during peak months or stronger topical solutions. Don’t let mosquitoes dictate your lifestyle — with the right habits, you can enjoy every sunset, siesta, and sangria in peace.
