Moving to Southern Europe? Your Mosquito Protection Guide

You did it. You sold the house in Rotterdam, left the drizzle behind, and signed the lease on a sun-drenched apartment overlooking the Mediterranean. The terrace is perfect. The light is golden. The neighborhood bar serves espresso that changes your understanding of coffee.

Then June arrives, and you discover what the relocation blogs never mentioned: the mosquitoes.

Every year, thousands of northern Europeans, British, Americans, and digital nomads relocate to southern Europe and are blindsided by their first mosquito season. This guide is written for you -- the expat who has never needed to think seriously about mosquitoes before. It covers the first-summer shock, how to set up your home properly, local solutions that actually work, and products worth investing in.

The First Summer Surprise

Why Nobody Warned You

If you are moving from the UK, Scandinavia, the Netherlands, or northern Germany, your experience with mosquitoes is likely limited to occasional bites during a camping trip or a brief holiday annoyance. Southern European mosquitoes are a different proposition entirely.

The mosquito season in coastal Spain, southern France, Italy, Greece, and Portugal runs from April through November -- that is 7-8 months of active mosquitoes. In some areas, particularly near wetlands, river deltas, or irrigated agriculture, there is no meaningful break from mosquitoes at all during summer.

The Asian tiger mosquito (Aedes albopictus) has made things significantly worse. Unlike native European mosquitoes that primarily bite at dawn and dusk, the tiger mosquito is an aggressive daytime biter. It is now present in 16 European countries and 369 regions. If you are moving to coastal Spain, anywhere in Italy, southern France, or the Greek mainland, you will encounter it.

The Health Dimension

This is not just about itching. Europe recorded record mosquito-borne disease transmission in 2025, including:

• 1,096 locally acquired West Nile virus cases across Italy, Greece, France, Spain, and several Balkan countries, with 95 fatalities.
• 304 locally acquired dengue cases, a sharp increase from 130 in 2023.
• 27 chikungunya outbreaks, a new record for the continent.

As an expat without prior exposure, your immune system has no familiarity with these pathogens. Taking mosquito protection seriously is a health decision, not just a comfort choice.

Setting Up Your Home: The Expat Checklist

Window Screens: Priority Number One

Your first investment should be quality window screens for every opening in your home. In northern Europe, window screens are uncommon because they are rarely needed. In southern Europe, they are as essential as locks on your doors.

Options by housing situation:

• If you own: Install fixed aluminum-frame screens or retractable roller screens. Budget EUR 60-200 per window depending on size and mechanism. Hire a local mosquitero installer -- they exist as a trade specialty in Spain, Italy, and Portugal. Ask at your local ferreteria (hardware store) for recommendations.
• If you rent: Magnetic screens are your best friend. They attach without drilling, can be cut to fit non-standard windows, and are removable when you leave. Brands widely available in Mediterranean hardware stores cost EUR 10-30 per window.
• Doors: Plisse (pleated) screens for balcony doors allow you to pass through while maintaining a seal. Bead curtains are culturally iconic in Mediterranean homes but provide zero mosquito protection -- they are for flies, not mosquitoes.

The critical mistake: Many expats screen only the bedroom, thinking that is where protection matters most. Screen every room. Mosquitoes that enter through an unscreened kitchen window at 19:00 will find your bedroom by midnight.

The Water Audit

Walk your property -- inside and out -- and eliminate every source of standing water:

• Balcony plant saucers: The most common urban breeding site in Mediterranean cities. Empty them after watering or use sand in the saucer to absorb excess water.
• Air conditioning drip trays: External AC units often drip into a tray or gutter that collects water. Ensure drainage flows freely.
• Roof terraces: Check drains for blockage. Puddles on flat roofs are prolific breeding sites.
• Courtyards: Traditional Mediterranean courtyard homes often have floor drains, fountains, or planting beds with poor drainage. Inspect weekly.

Air Conditioning vs. Open Windows

This is the great expat debate. Air conditioning keeps mosquitoes out (closed windows) and reduces room temperature and humidity below their comfort zone. But many expats moved south precisely for the open-air lifestyle -- shutting windows and running AC feels like a betrayal of the purpose.

The answer is both: screens on windows so you can live with them open, and AC for the hottest hours when you would close windows anyway. This combination gives you the Mediterranean lifestyle without the Mediterranean bites.

Local Solutions: What Actually Works

The Farmacia Arsenal

Every pharmacy in southern Europe stocks mosquito products. Here is what to look for:

• Picaridin-based repellent (20%): Sold under brand names like Autan, Relec, or local equivalents. Odorless, fabric-safe, and effective for 8-12 hours. This is your daily repellent.
• DEET-based repellent (30-50%): For high-risk evenings or travel to heavily infested areas. Effective but has a strong odor and can damage some synthetic fabrics and plastics.
• After-bite products: Ammonia-based pens (like AfterBite) or hydrocortisone creams. You will use these.

Electric Mosquito Devices

Southern Europeans are familiar with enchufes anti-mosquitos (plug-in mosquito devices). These heat a liquid or tablet containing pyrethroids, releasing vapor that irritates and repels mosquitoes. Brands like Raid and Bloom dominate the market.

They work in small, enclosed rooms but have limitations:

• Effectiveness drops in rooms larger than 25-30 m2.
• Open windows reduce efficacy significantly.
• Nightly chemical inhalation is a reasonable concern for long-term use.

Use them as a supplement to screens, not a replacement.

Mosquito Coils

Green spiral coils are ubiquitous on southern European terraces. They produce a pyrethroid-laced smoke that deters mosquitoes in a radius of about 2-3 meters. Useful for outdoor dining but not for indoor use -- the smoke is an irritant and potential carcinogen with prolonged exposure. Keep them on the terrace.

Community Fumigation

In many Spanish and Italian municipalities, local authorities conduct mosquito fumigation (fumigacion) of public spaces, particularly in coastal towns. Check your local ayuntamiento (town hall) or comune website for schedules. These treatments reduce but do not eliminate local populations.

Some urbanizations (housing developments) and communities of property owners conduct private fumigation of common areas. If your development offers this, participate and contribute to the shared cost. Mosquito control works best at the community level.

Country-Specific Notes

Spain

The Aedes albopictus is established along the entire Mediterranean coast and is spreading inland. The worst areas for mosquitoes include the Ebro Delta (Catalonia), the Albufera wetlands (Valencia), the Costa del Sol coast, and the Balearic Islands. Inland cities like Madrid have a shorter, milder season. Spanish pharmacies (farmacias) are well-stocked with repellents. Look for mosquiteras (window screens) at Leroy Merlin, Bricomart, or local ferreterias.

Italy

Italy recorded 773 West Nile virus cases in 2025 alone -- the highest in Europe. The Po Valley (Lombardy, Veneto, Emilia-Romagna) is particularly affected due to flat terrain, rice paddies, and irrigation canals. Rome, Naples, and Sicily have intense urban mosquito populations. Italian hardware stores (ferramenta) stock screens, but many expats find online retailers offer better selection for non-standard window sizes.

Portugal

The Algarve coast and Lisbon metropolitan area have growing tiger mosquito populations. The Ria Formosa wetland system along the southern coast creates intense breeding habitat. Portugal is slightly behind Spain and Italy in consumer mosquito product availability -- order specialty items from Spanish or EU-wide online retailers.

Greece

The Greek mainland and larger islands (Crete, Corfu, Rhodes) have significant mosquito pressure, particularly near agricultural areas and still-water bodies. Greek pharmacies stock local and international repellent brands. West Nile virus has been circulating in Greece for over a decade, with regular summer outbreaks.

Southern France

The Camargue delta, the Riviera coast, and the Languedoc region have the highest mosquito pressure. France has an active national mosquito surveillance program, and municipalities conduct public treatment programs. French pharmacies offer excellent repellent products. Look for screens (moustiquaires) at Castorama, Leroy Merlin, or specialized online retailers.

The Expat Learning Curve

Most expats go through predictable phases:

Year 1: Shock. Underestimation. Bitten constantly. Frantic pharmacy visits. Emergency screen purchases in July when the problem is already at peak.

Year 2: Preparation. Screens installed before the season. Repellent stocked. Terrace setup adjusted. Significantly fewer bites.

Year 3+: Mastery. Screens maintained and replaced as needed. Water management is automatic. Fan placement is optimized. Mosquito season is a managed inconvenience rather than a crisis.

Skip straight to Year 3 by preparing before your first summer. Install screens in March or April. Stock repellent. Learn your region's peak season. Audit your home for standing water. Talk to your neighbors -- they have been managing this for decades and will have specific, localized advice that no guide can replace.

Welcome to the Mediterranean

The mosquitoes are the tax you pay for year-round sunshine, outdoor dining in February, and the kind of quality of life that made you relocate in the first place. It is an entirely manageable tax. With proper preparation, your summer evenings will be spent on the terrace with a glass of local wine, not in the bedroom hunting a mosquito with a rolled-up magazine.

Welcome to southern Europe. Screen your windows.
