Biting Back: How to Time and Kit a West Highlands Trip Around the Midge

Every summer, somebody comes back from a week in the Highlands with a face like a dot-to-dot puzzle and announces that Scotland is ruined. It is not. They just pitched in a sheltered, boggy glen in early July and ate their dinner outside at dusk.

Midges are predictable little creatures. Understand what drives them and the West Highlands becomes one of the best places in Britain to spend a week in a tent, head net and all.

How the midge season actually works

The Scottish midge is a small, unremarkable fly with an outstanding talent for ruining a barbecue. The females bite, mostly for the protein to develop eggs, and the first big hatch generally lands in the second half of May once the ground has warmed up.

Peak misery runs from late May through to about the third week of August, with July usually the worst of it. Activity tails off sharply into September as nights lengthen and temperatures drop. A hard frost effectively ends the party.

The conditions that suit them are narrow: still air, high humidity, overcast skies and temperatures above roughly 7C. They are strongest at dawn and dusk, and they will happily bite all day if it is grey, damp and windless.

Which gives you the two levers that matter most.

Wind. A steady breeze of around 5mph or more thins them out dramatically - they are weak fliers and will not work against it. Dryness and sun. Bright, low-humidity weather knocks them back hard. Walking in the middle of a sunny afternoon in June is often completely fine.

When to go

April and early May are excellent - the season has not really started and the hills are still quiet. Late September and October are arguably better still: no leaves on the birches, no midges, and the light is superb.

If it has to be summer, aim for the coast and the islands. Tiree, the Outer Hebrides and much of the far north-west coast get enough wind that midges are a minor nuisance rather than a dominant theme. The east side of the country - Aberdeenshire, the eastern Cairngorms, the Moray coast - is markedly better than the west in July.

Where you go within the west matters just as much. Exposed coastal headlands and high, breezy passes are far more comfortable than wooded glens with a burn running through them.

Where to pitch

Choose a spot that catches the breeze. A ridge, a raised shoulder above a loch, or a machair pitch near the shore will give you a fraction of the bites of a forest clearing. Avoid boggy ground, avoid deep tree cover and avoid anything described in a guidebook as a sheltered spot, because sheltered is precisely the problem.

If you are wild camping, remember the access rights come with responsibilities - keep groups small, leave no trace, and stay out of enclosed land and buildings.

Shelters worth carrying

A tent with a proper inner. Standard no-see-um mesh is fine for midges, but check the geometry. A tent with a big open door and a shallow porch gives you nowhere to sit in the evening that is not full of midges. Look for a reasonably enclosed porch you can cook and eat in.

A head net. The single best value item in Highland kit. Two pounds of mesh that turns a ruined evening into an acceptable one. Buy one with fine mesh and a decent brim so it holds off your face.

A net inner or midge tent. If you use a tarp, add a hanging mesh inner. It gives you a midge-free zone to eat in with a view, and it weighs very little.

A bothy bag. Less about midges than about wind and rain, but a four-person bothy bag doubles as a communal midge refuge for lunch stops when the wind drops.

Repellents, honestly assessed

Two ingredients have real evidence behind them. DEET at 50 percent is the gold standard and works for hours, but it melts plastic - watch your sunglasses, camera body, watch strap and tent fabric. Picaridin-based products are nearly as effective, kinder to kit and less greasy, and most people find them more pleasant to use.

There is also a long-running folk theory about a certain brand of bath oil. Treat it as folklore. It is not a licensed repellent and it will not save you in a bad glen.

For clothing, permethrin treatment helps and lasts several washes. It is particularly good for socks, ankles and the cuffs of your trousers, which are the bits nearest the ground where the bites pile up.

Clothing that actually helps

Cover up. Long sleeves and trousers at dusk reduce the target area and are warmer than they sound in a Highland evening.

Light colours are easier to spot the little horrors on. Thin, long socks pulled up over the ankle are worth the fashion hit. A buff pulled up over the neck and ears helps, and a light sun glove or thin liner glove keeps your hands usable while you cook.

The camp routine

Pitch early, before the evening hatch. Eat before dusk or eat inside. Keep the tent zipped shut even for a moment's absence. Hang damp kit rather than stacking it in the porch, because wet gear is a midge magnet. A gas-powered area repellent unit genuinely works in a porch or under a tarp if you can carry the weight and the refills.

And when the swarm arrives, go to bed. The midges will still be there at six in the morning, but so will the sun and the breeze, and by eight you will have the place to yourself again.

The midge kit shortlist

• Head net with brim
• Picaridin or 50 percent DEET repellent
• Permethrin spray for socks and trouser cuffs
• Long sleeves, light colours, ankle-covering socks
• Tent with a closable porch, or tarp plus mesh inner
• Bothy bag for exposed lunch stops
• Small dry bags to keep damp kit away from you

Get the timing right, pitch where the wind reaches, and the West Highlands in summer stops being a battle and starts being a holiday.
