Thermacell Fuel-ZoneGuard Backpacker Mosquito Repeller
A camp mosquito repeller that runs on your stove fuel
A compact repeller that screws onto a backpacking fuel canister (sold separately) and heats a DEET-free mat to create a 15 ft zone in about 15 minutes. It weighs about 4 oz and includes 16 hours of refills.
Our take
The problem with this repeller isn't the repeller. It's the fuel. It screws onto a backpacking fuel canister, sold separately, and those canisters aren't allowed in carry-on or checked bags.
If you already cook on a canister stove, that's no extra burden. It weighs about 4 oz, it's DEET-free and spray-free, and Thermacell says it clears a 15 ft zone in about 15 minutes. Sixteen hours of refills come in the box, enough for a good run of buggy evenings at camp. Fly to the trailhead, though, and you're hunting for a canister before it does anything. Like any area repeller, it stops helping once you walk away.
Here's the honest call. Campers who drive in with a stove should get it. If you fly to your trips, save the money and pick a rechargeable repeller or a skin repellent.
Who it’s for
Backpackers and campers who already carry a canister stove and want mosquito protection at camp without batteries.
Skip it if
Skip it if you fly to most of your trips or don't cook on a canister stove. A rechargeable repeller or skin repellent travels far easier.
Thermacell Fuel-ZoneGuard Backpacker Mosquito Repeller: questions people ask
Can you bring a butane or camping fuel canister on a plane?
No. Camping fuel canisters aren't allowed in carry-on or checked bags, so buy one after you land.
Is Thermacell safe to use without DEET?
This repeller is DEET-free and spray-free. It heats a repellent mat to protect an area, so follow the label and only use it outdoors.
How far does a backpacking mosquito repeller reach?
This one is rated for a 15 ft zone. Wind and moving around shrink it, so it works best while you sit at camp.
