Are Mosquito Nets Worth It in Spain? What Actually Works

Short answer: Yes, mosquito nets are worth it in Spain — particularly window nets. They solve the core summer problem: keeping windows open for ventilation without letting mosquitoes in. Here’s what you need to know before buying.

Are Mosquito Nets Actually Necessary in Spain?

This depends on where you live and what you value most. If your apartment has air conditioning and you’re happy to sleep with windows closed, you may never need a net. But most people who move to Spain discover quickly that the choice between “open windows and mosquitoes” or “closed windows and sweltering” is one of the genuine discomforts of summer here.

Window insect screens change that equation entirely. They’re not a luxury — they’re the standard solution residents in southern Spain have used for decades.

The areas where nets make the biggest difference:

• Coastal Andalucía — particularly near the Guadalquivir marshes, wetlands, and any property close to standing water
• Valencia and Murcia coast — rice paddies and irrigation infrastructure create year-round mosquito habitat
• Balearic Islands — late season (September–October) can be worse than mid-summer in some areas
• Anywhere near irrigated gardens or communal pools

If you’re in central Madrid at altitude or on a breezy hilltop inland, your mosquito exposure will be lower — but most expats in Spain are on the coast, which is where this matters.

Window Nets vs Bed Nets: Which Should You Get?

This is the most common question expats ask, and the answer is almost always the same: window nets first, bed nets as a backup.

Window Insect Screens (Recommended)

Window screens attach to the frame of an open window and create a permanent barrier. You get full ventilation, no mosquitoes.

Types available in Spain:

• Adhesive frame kits — Self-adhesive or Velcro-edged fiberglass mesh. Inexpensive (€10–25 per window), available at Leroy Merlin, Bricomart, or Amazon.es. Easy to install without drilling, and removable. Best for renters.
• Magnetic insect screens — Snap into the frame magnetically. Better for doors and large openings where you walk through frequently. €25–60 depending on size.
• Roller screens — Permanently installed, roll up like a blind. Professional installation, more expensive (€80–200+ per window), but seamless.

Most expats in rented apartments use the adhesive kit approach. You can buy a roll of fiberglass mesh and self-adhesive framing from any large hardware store in Spain and cover multiple windows for under €40 total.

Bed Mosquito Nets

Bed nets work well in standalone houses where you can hang them from a ceiling hook or beam. In typical Spanish apartments, there’s often nothing to attach them to without drilling.

If you do want a bed net, a simple canopy style (which hangs from a single central point) is the most practical for apartments. They’re sold in Chinese bazaar stores, Decathlon, and on Amazon.es.

Bed nets are particularly useful when:

• You’re staying in an unfurnished holiday rental without window screens
• The infestation is bad enough that screens alone aren’t sufficient
• You have small children and want extra protection during sleep

For long-term residents, investing in window screens is almost always the better solution.

When Is Mosquito Season in Spain?

Spain’s mosquito season runs longer than most new arrivals expect.

Month	Activity level
January–March	Minimal (near zero in most areas)
April	Low but increasing
May–June	Moderate — season begins
July–August	High — peak daytime activity of tiger mosquito
September–October	Often the worst month in many coastal areas
November–December	Declining but not zero in the south

September is frequently worse than August. Slightly cooler temperatures, autumn rain filling standing water, and a summer’s worth of breeding cycles create a population peak many residents don’t anticipate. On Mallorca and parts of the Costa del Sol, mosquito activity can persist well into November.

Is the Tiger Mosquito a Real Threat?

The tiger mosquito (Aedes albopictus) deserves specific mention because it’s fundamentally different from the common mosquito in one key way: it bites during the day.

The common mosquito (Culex pipiens) is most active at dusk and during the night. This is why many people with window nets and closed bedroom windows still get bitten — the tiger mosquito gets you while you’re having coffee on the terrace at 9am or gardening in the afternoon.

Tiger mosquitoes are recognisable by their striking black and white striping, aggressive daytime behaviour, and tendency to target lower legs and ankles. They were first detected in Spain in 2004 and are now established across the entire Mediterranean coast and in Catalonia.

The disease risk in Spain is real but currently low. While the tiger mosquito can carry dengue, Zika, and chikungunya, local transmission cases in Spain remain uncommon. The discomfort and nuisance value, however, is considerable — particularly for those living near parks, gardens, or any standing water.

Window screens work on tiger mosquitoes. Standard fiberglass mesh stops them completely. The challenge is that you’re exposed during outdoor time, not just when sleeping.

What Else Works Alongside Nets?

Window nets are passive protection. For complete coverage, pair them with:

1. Eliminate standing water weekly Tiger mosquitoes breed in tiny volumes of water — a saucer under a plant pot, a bottle cap, a tarpaulin fold. Doing a weekly check of your terrace and garden and tipping out any standing water dramatically reduces the local population.

2. Plugin repellent liquids Products like Bloom or Raid Max electric liquid vaporisers are effective in enclosed rooms. They plug into a standard socket and release a low-level insecticide continuously. EU-approved, considered safe for adults and older children, widely used by year-round residents throughout southern Spain.

3. Chemical repellents for outdoor time For time on terraces, in gardens, or walking near water: repellents containing DEET (20–50%), icaridin (Picaridin), or oil of lemon eucalyptus (PMD) are all effective against Spanish mosquito species. Apply to exposed skin before going out in the evening or early morning.

4. A fan Mosquitoes are weak fliers. A pedestal or desk fan pointed at your sleeping area creates enough airflow to make it difficult for mosquitoes to land and bite. Not a replacement for screens, but useful as supplementary protection.

Where Can You Buy Mosquito Nets in Spain?

You don’t need to import them. Mosquito screens are readily available across Spain:

• Leroy Merlin — Largest selection of window screen kits and roller systems
• Bricomart — Good range of adhesive kits, often cheaper than Leroy Merlin
• Decathlon — Bed canopy nets and pop-up camping nets
• Chinese bazaar stores — Cheap adhesive window kits, bed nets
• Amazon.es — Wide selection, useful for larger or unusual window sizes
• Local hardware stores (ferreterías) — Often stock adhesive mesh rolls and framing strip

For standard apartment windows, expect to pay €10–25 per window for a good adhesive kit, or €3–10 at a bazaar store for a basic version.
