10 Expert Tips on How to Deter Mosquitoes

Nobody enjoys the constant buzz of mosquitoes, or worse, the itchy bites they leave behind.

While the UK doesn't have a serious mosquito problem compared to tropical climates, these insects can be a real seasonal nuisance, especially during the summer. A bit of prevention goes a long way: put a few simple measures in place and you can stop mosquitoes settling into your garden or home before they ever become a problem.

This guide is deliberately prevention-first — ten practical ways to deter mosquitoes and keep them away from your space. If you're already dealing with an active problem, or you want the full picture on lifecycle, bite treatment and when to call a professional, our expert guide to getting rid of mosquitoes covers that side. One quick sense-check before you start: if the thing biting you outdoors at dusk is tiny and comes in swarms, that's far more likely to be midges than mosquitoes — it's the single most common mix-up we see, and the two need slightly different handling.

1. Eliminate Standing Water

Mosquitoes need stagnant water to breed, as female mosquitoes lay their eggs on the water's surface. Removing potential breeding grounds is your single highest-impact first line of defence.

• Empty plant saucers, buckets, and outdoor containers, including after rain.
• Regularly clean and refill birdbaths and pet water bowls.
• Check for clogged gutters and drains, as these often hold hidden water.
• Cover water butts with tightly fitted lids.

2. Keep Your Garden Tidy

Overgrown gardens are paradise for mosquitoes, especially if they contain damp, shady areas that offer shelter from the wind or sun.

• Trim long grass, bushes and hedges to reduce potential hiding spots.
• Remove garden debris, such as piles of leaves, where water can collect.
• Keep sheds and greenhouses dry and ventilated throughout the year.

3. Use Mosquito-Repelling Plants

Certain plants are popular for naturally deterring mosquitoes thanks to their strong scents. They're worth adding to a garden or balcony to make a space a little less inviting — but keep expectations realistic: the scent only acts over a short range, right next to the plant, so position them close to seating areas, doorways or windows where they'll actually do something.

• Lavender
• Citronella grass
• Basil
• Lemongrass
• Marigolds

4. Install Window and Door Screens

Most UK homes don't come with window screens by default, which makes it very easy for mosquitoes to get inside when they're around. Fitting mesh screens on windows and doors is a simple, effective way to keep mosquitoes out while still letting fresh air circulate — and it's one of the few measures that works around the clock without any effort from you.

5. Use Outdoor Fans

Mosquitoes are surprisingly weak fliers and tend to avoid areas with strong air currents. An outdoor fan near a seating or dining area keeps them off you — and keeps you cool on warm summer evenings, exactly when you're most likely to be sitting outside.

6. Switch to Yellow Outdoor Lighting

Mosquitoes are drawn to certain wavelengths of light, particularly blue and ultraviolet. Switching outdoor bulbs to yellow or "bug light" tones makes your home and garden less appealing to them — a small, set-and-forget change.

7. Wear Light-Coloured Clothing

Mosquitoes are naturally drawn to dark colours, which provide better contrast for them to home in on. Light-coloured, loose-fitting clothing helps when you're outdoors, especially at dawn or dusk when mosquitoes are most active. It's a useful rule of thumb for packing, too, if you're heading somewhere mosquitoes are common.

8. Use Natural or Chemical Repellents

For personal protection, a proper repellent is what does the heavy lifting — and it only works where you actually apply it.

• Natural options: citronella oil, eucalyptus (PMD) or lemon balm-based sprays.
• Chemical options: products containing DEET or picaridin offer the longest-lasting protection. You'll find options in our mosquito repellents range.

Apply repellent to exposed skin and reapply as the label directs. Around a patio or seating area, citronella diffusers and coils can reduce mosquito pressure too — but treat them as a supplementary layer rather than a force field. Diffusers tend to outperform candles, which are widely overrated; in heavy conditions you'll still want repellent on your skin.

9. Use Mosquito Traps

Mosquito traps can help reduce numbers in your immediate area. They work by attracting mosquitoes with carbon dioxide or UV light and capturing them so they're unable to escape. Treat them as a supporting tool rather than a standalone fix — they thin out adults, but won't keep pace with a breeding site you haven't dealt with.

• Place traps near standing water or in areas where mosquitoes are known to gather.
• Clean traps regularly to maintain their effectiveness.

10. Treat Breeding Areas with Mosquito Dunks

If you have water features like ponds or fountains you can't drain, use mosquito dunks. These contain a naturally occurring bacteria (Bti) that specifically targets mosquito larvae without harming fish, pets, or plants — a tidy way to deal with the one water source you can't simply tip out.

Bonus Tips for Mosquito-Free Living

A few extra habits that help — at home and abroad:

• Time your outdoor activities: avoid being outside during peak mosquito activity, usually at dawn and dusk.
• Create barriers: hang mosquito nets over outdoor seating, or use pop-up gazebos with mesh sides.
• Stay fragrance-free: strong perfumes and aftershaves can attract mosquitoes, so stick to unscented products during mosquito season.

FAQs: deterring mosquitoes

What keeps mosquitoes away naturally?

Removing standing water is the most effective natural step by far, because it stops them breeding in the first place. After that, an outdoor fan, window screens, light clothing and scented plants around seating areas all help. For personal protection, a repellent on the skin still does the real work — the natural measures reduce pressure rather than guarantee a bite-free zone.

What smell do mosquitoes hate?

Lavender, citronella, lemongrass, basil, peppermint and eucalyptus are the scents most often cited. They can make a seating area less inviting, but the effect is short-range and supplementary — useful alongside repellent and screens, not as a replacement for them.

Do citronella candles actually work?

Less than their reputation suggests. Citronella does have repellent properties, but candles tend to underperform — a diffuser or coil that releases scent steadily does better, and even then only over a small area. For reliable protection, repellent on your skin is what counts.

Do mosquito-repelling plants work?

Modestly. The fragrance only deters mosquitoes very close to the plant, so a single pot in the corner won't clear a garden. Grouped near doorways and seating they can take the edge off, but treat them as one layer among several rather than a standalone solution.

How do I keep mosquitoes away at night?

Fit screens on the windows and doors you keep open, clear any indoor standing water, and run a fan in the bedroom — the draught keeps weak-flying mosquitoes off you. A repellent before bed adds a further layer during a bad spell.

Is it mosquitoes or midges in my garden?

If the biters are tiny, hard to see and swarm at dusk — especially near water — they're most likely midges. Mosquitoes are larger, give off a whine, and are the ones more likely to bite you indoors overnight. Our midge guide covers that side if it sounds more like your situation.

Final Thoughts

Deterring mosquitoes isn't just about comfort — it's about protecting your health too, since bites can occasionally cause a stronger reaction. With these simple, prevention-first measures, you can keep numbers down around your home and enjoy your outdoor spaces without constantly swatting.
