How to Avoid Midges in Scotland — What Actually Works

1. Check the Forecast Before You Go

This is the single most useful thing you can do. Midge activity varies enormously from day to day based on wind, cloud cover, humidity, and temperature. A forecast showing moderate winds (10mph+) means a dramatically better day outdoors than one showing calm, overcast conditions — even in peak July.

BiteForecast provides location-specific midge risk estimates based on local weather data. Check it before planning outdoor activities, particularly if you're choosing between locations or deciding whether to pitch a tent for the night.

2. Choose Your Timing Carefully

Within the season: May and September are significantly better than June, July, and August. If you have flexibility on when to visit the Highlands, late May or early September offers much of the beauty with a fraction of the midge pressure.

Within the day: Midges are most active at dawn and dusk. The middle of the day — particularly in sunny or breezy conditions — is dramatically safer. Plan sunrise walks for later in summer when you're already into peak midge hours at 5am.

Watch the weather: A breezy day is always better than a calm one. Rain during the day suppresses activity, though the calm period after rain can see a surge.

3. Use an Effective Repellent

Not all repellents are equal against Scottish midges. Here's what works:

DEET remains the gold standard. Products containing 30-50% DEET provide reliable, long-lasting protection. Apply to exposed skin and reapply after swimming or heavy sweating. DEET is effective against midges, mosquitoes, and ticks — useful across Scottish outdoor activities.

Smidge is a Scottish-developed midge repellent using Saltidin (Picaridin) as its active ingredient rather than DEET. It has developed a strong reputation among hillwalkers, campers, and outdoor workers in Scotland for effective, comfortable protection without the feel and smell of DEET. Many Scottish outdoor enthusiasts now prefer it. Available at outdoor shops across Scotland and online.

Avon Skin So Soft has a near-legendary status as a midge repellent in Scotland, particularly among hillwalkers and military personnel who train in the Highlands. It is not technically formulated as an insect repellent — it's a moisturiser — but something in its formulation discourages midges reliably enough that it has been standard kit in parts of the British Army for decades. The dry oil spray version is the one most commonly used for midges.

Lifesystems Expedition products offer high-strength DEET formulations designed for severe conditions. The Expedition 100+ provides maximum-strength protection for the most challenging midge environments.

What doesn't work: Electronic repellers, ultrasonic devices, vitamin B supplements, and most "natural" alternatives have little to no evidence of effectiveness against Culicoides impunctatus. Save your money.

4. Wear the Right Clothing

Physical barriers are reliable where repellent alone isn't enough — particularly in severe conditions.

Cover up. Long sleeves, long trousers, and socks eliminate most bite opportunity. Midges target exposed skin. A full covering in calm conditions is often more practical than heavy repellent application.

Light colours. Midges are attracted to dark colours. Light-coloured clothing won't eliminate the problem but marginally reduces attraction.

A midge hood or head net is the most effective piece of kit for the face and neck — the areas where midge bites are most unpleasant and where repellent can be hardest to apply effectively. Fine mesh hoods that fit over a cap are widely available at Scottish outdoor shops. They look slightly eccentric but they work.

Tightly woven fabrics. Standard loosely woven fabrics can allow biting through the material. Tightly woven technical fabrics provide better protection.

5. Choose Your Camp Spot Wisely

If you're wild camping or staying at a campsite in the Highlands, location matters enormously.

Wind exposure is the priority. A slightly exposed spot with consistent airflow will be dramatically more comfortable than a sheltered, boggy hollow — even if the hollow looks more picturesque. Midges cannot fly effectively in even moderate wind.

Avoid boggy ground. Wet, peaty areas are breeding habitat. Camping near a bog in July is asking for trouble.

Elevation helps. Higher ground is generally windier and cooler — less comfortable for midges, more comfortable for you in calm conditions.

Water's edge can go either way. A lochside with a breeze off the water can be midge-free. A sheltered lochside in calm conditions can be one of the worst places to be.

6. Inside Your Tent

Standard tent mesh does not keep midges out. They are small enough to pass through most netting.

Purpose-made midge-proof mesh is available for some tents and is worth using if you're camping in peak season in the worst areas.

Keep the tent closed. A calm evening in the Western Isles means midges everywhere — don't leave doors or vents open longer than necessary.

A small battery-powered fan inside a tent creates enough airflow to deter midges and makes warm nights more comfortable.

7. After the Bite

Despite your best efforts, bites happen. What helps:

Don't scratch. It makes the itching worse and the welt larger. Easier said than done.

Cold water applied immediately reduces the initial reaction.

Antihistamine cream (hydrocortisone or similar) reduces itching and inflammation. Worth carrying in your kit.

Oral antihistamines help if you're particularly reactive or have been heavily bitten.

After-bite sticks containing ammonia or antihistamine provide quick relief.

The Honest Summary

Midges are part of the Scottish Highlands experience. They are worst in certain places, at certain times, in certain conditions — and much more manageable than their reputation suggests if you're prepared. The people who have the worst experiences are usually the ones who didn't know to check the forecast, didn't bring repellent, and happened to camp in a sheltered glen on a calm July evening.

Check the forecast. Bring Smidge. Carry a head net. Pick a breezy spot. You'll be fine.
