You've tried the candles. You've sprayed yourself down. You've retreated indoors twice already this week. And yet, somehow, you're still getting bitten.
The frustrating truth is that most midge control efforts fail not because the products don't work — but because of what's happening around them. Midges are small, they move in swarms, and they exploit every gap in your defences with impressive efficiency. Getting on top of them means closing those gaps one by one.
Here are the ten most common reasons midges are still winning — and exactly what to do about each one.
1. You're outside at the wrong time of day
This is the biggest one, and the one most people never fix.
Biting midges are most active at dawn and dusk. On overcast days they'll bite throughout the afternoon, but in clear conditions the windows around sunrise and sunset are when activity peaks. If you're sitting in the garden at 7pm on a still June evening wondering why nothing is working, timing is almost certainly part of the problem.
The fix: Shift outdoor time to the middle of the day where you can. Even moving your evening meal or drinks 30–45 minutes earlier makes a meaningful difference in midge pressure. It won't always be practical, but on the days it is, it's the most effective single change you can make.
2. You're sitting in the wrong spot
Midges thrive in still, sheltered, humid conditions. That shaded corner of the garden with the lovely lush borders and no breeze? That's prime midge territory. The exposed patio in full sun with a bit of airflow? Far less so.
The fix: When choosing where to sit, factor in air movement. Even a light breeze significantly reduces midge activity — they're weak fliers and struggle to operate in moving air. If you have options, choose the more exposed spot. If your main seating area is sheltered, a garden fan can make a surprising difference on still evenings.
3. Your repellent coverage has gaps
Insect repellent only works where you've put it. Midges are expert at finding the patches you missed — and they have favourites. The back of the neck, the hairline, behind the ears, the ankles, and the backs of the wrists are the spots that most commonly get missed during application.
The fix: Apply repellent methodically, not just to the arms and legs. Work from the ground up — ankles and lower legs first, then arms, then the back of the neck and hairline last. If you're in a high-midge area, treat exposed feet and sandal straps too.
4. Your repellent has worn off
Most repellents last between two and four hours under normal conditions. In hot weather, after exercise, or if you've been sweating, that window shortens considerably. People apply once, assume they're covered for the evening, and wonder why the bites start appearing two hours later.
The fix: Reapply on a schedule rather than waiting until you notice bites. In peak midge conditions — warm, humid, still evenings — treat every two hours as the standard interval, not the exception. Carry a small spray or pen format so reapplication is easy when you're away from home.
5. You're relying on citronella alone
Citronella candles, coils, and diffusers are useful tools — but they're widely misunderstood. They create a deterrent zone around a seating area, not a bite-free bubble. In moderate midge conditions they reduce pressure noticeably. In heavy midge conditions, particularly in known hotspots like the Scottish Highlands or Lake District, citronella on its own will not be enough.
The fix: Use citronella products as a second layer, not a first line of defence. On-skin repellent is non-negotiable in high-midge conditions. Citronella works best when it's complementing repellent — placed upwind of your seating area, in still or sheltered conditions, as part of a layered approach.
6. You're not positioning deterrents correctly
Even when people use citronella products, they often place them in the wrong spot. Directly on the table in front of you pushes the deterrent vapour away from where you're sitting. Downwind of your position means it drifts away from you entirely.
The fix: Place citronella coils or candles upwind of your seating area — so the vapour drifts toward you and the space you're occupying. In still conditions, position them at the edges of your seating area rather than in the middle. Two or three well-placed coils will outperform six badly placed ones.
7. Your garden is giving midges exactly what they need
Midges breed in boggy, damp ground and are drawn to lush, sheltered vegetation. If your garden has areas of poor drainage, persistent damp patches, dense leaf litter, or heavily shaded borders that stay moist, you're hosting conditions that attract midges close to the house.
The fix: Clear leaf litter from borders regularly, particularly in late spring. Check garden drainage and address any persistently waterlogged areas near seating. Keep grass cut — long, damp grass is ideal midge habitat. None of this eliminates midges entirely, but it reduces the population pressure immediately around your garden.
8. Your outdoor lighting is working against you
Cool white and bright white outdoor lights are highly attractive to flying insects. If you're lighting your garden or patio with standard white bulbs and wondering why insects are swarming around the area you're trying to relax in, your lighting is part of the problem.
The fix: Switch outdoor lights to warm white or yellow-spectrum bulbs. These are significantly less attractive to flying insects, including midges. Amber or sodium-style bulbs are the most effective. It won't eliminate the problem but it meaningfully reduces the draw — and it tends to create a pleasanter atmosphere anyway.
9. You're not covered up enough
This one sounds obvious but is regularly underestimated. Midges can bite through very thin fabrics, so a lightweight summer shirt isn't as much protection as it might feel. The clothing choices that actually help are slightly more substantial — and the colour matters too. Dark colours attract more insects than light ones.
The fix: In high-midge conditions, wear light-coloured, close-weave fabrics on arms and legs. Tuck trousers into socks if you're in a serious midge area — ankles are a primary target. For the face and neck in extreme conditions, a midge head net is unglamorous but genuinely effective.
10. You're treating it as a one-off rather than a routine
The most common pattern is this: someone gets badly bitten, buys a repellent, uses it once or twice, and then stops when conditions seem better — only to get bitten again two weeks later. Midge activity fluctuates week to week depending on weather, and a single good application isn't a season-long solution.
The fix: During peak season (June to August), treat midge protection as a routine rather than a reaction. Keep repellent stocked and accessible. Check the weather before outdoor events — calm, humid evenings after rain are the signal to step up protection, not the moment to realise you've run out. A small amount of consistent preparation goes much further than occasional scrambles for a solution.
The bottom line
Midges are relentless, but they're also predictable. They operate in specific conditions, at specific times, and exploit specific gaps. Close enough of those gaps — the timing, the positioning, the coverage, the layering — and you go from being bitten constantly to barely noticing them.
None of this requires expensive kit or complicated routines. It mostly requires understanding how midges actually work, and adjusting your habits to match.
