Thermacell for midges in Scotland and on the loch

Updated: October 2026

You are cooking at a Highland pitch or a still loch shore, and the midges arrive before the pan is hot. A Thermacell for midges in Scotland is a zone around that patch of ground, not a suit you wear on the path. UK camp write-ups and the amazon.co.uk extracts behind our [Thermacell mosquito repellent comparison](/hub/pest-control/thermacell-mosquito-repellent) were checked on 16 October 2026. Pack the device for a still seat. Do not pack it instead of a net.

What the midge claim actually is

Burton McCall, the UK distributor in Leicester, names midges in the same brand sentence as mosquitoes, and it describes a butane unit with a claimed 20 m² zone. That is a product claim. It is not a count of insects on Skye. The Backpacker title on amazon.co.uk also says mosquitoes and midges, and the target-species field on that listing still says mosquito. One UK review says the vapour seemed to reach about 30 cm. A loch-side review says a real swarm almost landed on the device, and another calls it not midgie-proof. The lighting sequence is on how to use a Thermacell.

What UK camp write-ups found

Dan Bailey’s MR300 piece on UKC Gear is one writer’s trips, not a percentage. On a windless Skye swarm he found no useful thinning. In Borrowdale, with fewer Lakeland midges and still air, he describes a quieter patch after about 15 minutes. Wind dispersed the zone, and the midges came back faster than the zone rebuilt. He kept Smidge and a head net. At Loch Tummel, in still air while cooking, there were fewer midges beside the unit, and some were still present. A breeze reduced the effect. Neither write-up measured a 20 m² circle. A light hatch is the case they half-support. A windless swarm is the case they do not.

What you still wear

A fine head net and a skin product stay in the pack. TGO Magazine and wild-camping accounts put those first for Highland midges, and they mention a Thermacell Backpacker as a reasonable extra beside the tent, not as the only layer. This page does not invent an aperture or a British Standard for the net. If the net is coarse enough that midges walk through, it is the wrong net. Smidge, or a DEET spray if that is what you tolerate, is the layer on your skin when you leave the seat. TGO has also mentioned picaridin as that magazine’s practice. The job split with 50% DEET is on Thermacell versus mosquito spray.

Where you may run it

Run it outside and upwind, and give it 10 to 15 minutes before you judge the hatch. The Backpacker sheet bars tents, caravans, boats, and cars because of carbon monoxide. “Tent sites” on an MR-300 bullet is a place you camp, not permission to run it inside the inner tent. If the forecast is a still swarm and you will be walking, leave the device at home and take the net. If you will cook in a sheltered spot and you already own the matching refill, it can be the extra by the stove.

Common questions

Do Thermacell devices work on Highland midges or only on mosquitoes?
They are sold with a midge claim, and some UK campers report fewer midges while they stay beside a running unit in still air. That is not the same as clearing a Highland swarm. UKC’s Skye evening found no useful thinning, and a Backpacker review from a Scottish loch says midges almost landed on the device. Use it as a still-air extra. Do not treat the title as a count.
Will one unit cover a loch-side cooking spot?
It can thin a light hatch in still air around the stove, which is what the Loch Tummel write-up describes: fewer midges, not zero. The claimed zone on the UK brand page is 20 m², and that figure is a claim, not a measurement from these trips. One unit does not cover a beach, a path, or a pitch once you walk away. Judge it after 10 to 15 minutes, not in the first minute.
What happens when the breeze keeps stopping and starting?
The plume drifts off, and the midges return faster than the zone rebuilds. That is the pattern in the UKC notes and in the Loch Tummel account. Place the unit upwind when the air is moving, and expect gaps when the wind shifts. A gusty bank is a poor place to rely on it. A skin product and a net do not care which way the breeze turned.
Should I still take a head net and Smidge?
Yes. The device does not replace them. Camp write-ups that found any use for an MR300 still carried a fine head net and a skin product such as Smidge. Wear the net when you leave the cooking spot, and use the skin product on the skin the net does not cover. A coarse mosquito net can let midges through. This page does not quote a mesh size.
Is the Backpacker’s midge title a test result?
No. The amazon.co.uk title names mosquitoes and midges, and the bullet claims 20 m². The specification field for target species says mosquito. UK reviews on that listing both praise a camp and describe a Scottish swarm sitting on the unit. Burton McCall’s midge sentence is a brand claim. Read it as a claim, then read the write-ups before you leave the net behind.
Can I put it in the tent doorway?
Not if the doorway is closed into a porch or an awning. The Backpacker sheet bars tents, caravans, boats, and cars because of carbon monoxide, and Thermacell’s general line is outdoor only. A loch-side writer also kept the MR300 out of the tent. Put it in open air beside the stove, upwind, or do without it. Do not test the wording with a zipped door.
