Biting insects can ruin an otherwise perfect trip, and in some places they carry real disease, so protection is not a luxury. The frustrating part is how much money goes on things that barely work: citronella candles, ultrasonic gadgets and repellent wristbands consistently disappoint. What actually works is a layered defence, and it is not complicated. Treat your clothing so insects will not settle on it, put an effective repellent on the skin you cannot cover, and carry a physical barrier for the moments when the bugs win anyway. The picks below cover each of those layers rather than a single magic bullet.
Quick Picks
- Best area repeller: Thermacell MR450 — creates a scent-free protection zone around camp.
- Best for backpacking: Thermacell Backpacker — screws onto your stove’s gas canister, ultralight.
- Best skin repellent: Picaridin spray (Ranger Ready / Natrapel) — effective, non-greasy, DEET-free.
- Best clothing treatment: Sawyer Permethrin — treat clothes and tent for weeks of bug protection.
- Best physical barrier: Mesh head net — cheap, foolproof defence when the bugs are unbearable.
Building a Defence That Works
Think in layers rather than looking for one product to do everything, because no single item covers every situation. The base layer is treated clothing, which stops insects landing on the fabric you wear. On top of that goes a skin repellent for exposed hands, face and ankles. Area protection can hold a bug-free zone around a still camp, and a head net is the last resort when the swarm is genuinely bad. Work out which layers your trips demand, then choose a good product for each.
For skin, the active ingredient is what matters, not the brand on the bottle. Picaridin at around twenty percent gives long-lasting protection without the greasy feel of DEET or its habit of softening plastics and synthetic gear, which makes it the sensible default for most campers. DEET still works and lasts, especially at higher concentrations, but treat your kit carefully around it. Plant-based options built on lemon eucalyptus oil can work for shorter periods. Whatever you pick, buy for the active ingredient and apply it properly rather than sparingly.
The most underused layer is treating your clothing, and it is the one that changes trips. Permethrin is applied to fabric, not skin, and it repels and kills insects that land on the treated clothing, lasting through several washes. A set of treated trousers, a long-sleeved shirt and socks does a great deal of the work before any skin repellent is involved. It is especially worth it in tick country, where keeping insects off your legs matters most. Treat the gear at home and let it dry fully before you wear it.
For a settled camp, area protection such as a portable unit that spreads repellent into the still air around you can hold a comfortable zone, though it needs calm conditions and does little in a breeze. A fine mesh head net weighs almost nothing and is the one thing that always works when the insects are unbearable, turning a miserable evening into a manageable one. A tent with a good mesh inner completes the picture by giving you a bug-free place to sleep.
Spend on the things that are proven to work: a picaridin or DEET skin repellent, permethrin for your clothing, and a decent head net that costs very little. Save your money by ignoring citronella candles, ultrasonic repellers and wristbands, which the evidence simply does not support. The common mistakes are relying on one of those gimmicks and getting eaten anyway, applying too little repellent or missing the ankles and the back of the neck, and forgetting that treating your clothing does more than almost anything else you can carry.
Site choice and habits. The cheapest protection is free: camp in an open, breezy spot away from standing water and dense bush, empty any standing water around camp, and cover up at dawn and dusk with long sleeves and light-coloured, loose clothing. Good habits plus the right gear beat either alone. Have a quick look at the current and most recent options on Amazon for the insect and mosquito protection.

Thermacell MR450
The benchmark area repeller for camp. It heats a repellent mat over a butane cartridge to build a scent-free, spray-free protection zone of roughly 15 feet around you — fire it up at camp and the mosquitoes that were swarming simply disappear within minutes. Testers in genuinely buggy swamps and forests report it turning a miserable evening into a pleasant one with no DEET required. It needs fuel cartridges and mats on hand (mats last about 4 hours, fuel about 12), and works best in calm air, but for car camping and base camp it’s a game-changer. Have a quick look at the current and most recent options on Amazon for the Thermacell MR450.
Thermacell Backpacker
The ultralight repeller for hikers. Thermacell built this specifically for backpacking: it screws directly onto the same isobutane canister you already carry for your stove, so there’s no separate fuel to pack, and it builds the same protection zone at a fraction of the weight and bulk of the camp models. It’s the answer to setting up camp only to find the mosquitoes unbearable — fire it up after dinner and reclaim the evening. Too heavy and slow for a fast thru-hike, but ideal for weekend trips where you’ll sit at camp. Have a quick look at the current and most recent options on Amazon for the Thermacell Backpacker.
Picaridin Spray (Ranger Ready / Natrapel)
The modern skin repellent of choice. Picaridin matches DEET for effectiveness against mosquitoes and ticks but without the downsides — it’s non-greasy, low in odour, and safe on synthetics, plastics, and gear that DEET would damage. A fine-mist spray dries without a slimy film, and it’s pleasant enough to actually want to wear. For on-the-move protection where an area repeller can’t reach, a Picaridin spray is the easy, effective pick. Have a quick look at the current and most recent options on Amazon for the Picaridin insect repellent spray.
Sawyer Permethrin
The set-and-forget clothing treatment. Sprayed onto clothing and gear in advance and left to dry, it bonds to the fabric and repels and kills mosquitoes and ticks for around six weeks or six washes. Treat your hiking clothes, socks, shoes, and tent before you leave and you have all-week protection with nothing applied to your skin — and it’s the strongest defence against ticks. It pairs perfectly with a skin repellent on exposed areas. Apply it outdoors, let it dry fully, and never put it on skin. Have a quick look at the current and most recent options on Amazon for the Sawyer Permethrin clothing treatment.
Mesh Head Net
The cheap, foolproof barrier. When the bugs win — clouds of midges, a still swampy dusk — a fine-mesh head net slipped over a brimmed hat keeps every biter off your face and neck, with no chemicals and almost no weight or cost. It packs to nothing and lives in a pocket of the pack as insurance for the trips when repellents can’t keep up. Add a full bug jacket for the body in truly brutal conditions. Unglamorous, but nothing else is as reliable when it matters. Have a quick look at the current and most recent options on Amazon for the mosquito head net.

The Verdict
Effective insect protection is a layered system, not a single product, and the layers that work are well established. Treat your clothing with permethrin, put a picaridin or DEET repellent on exposed skin, add area protection for a still camp and keep a head net for the worst of it. Skip the citronella candles, wristbands and ultrasonic gadgets, because they will let you down. Build the layers to suit where you are going, and biting insects stop being the thing you remember most about the trip.
If you’re camping somewhere bugs are a concern, this is a sensitive topic for some — if biting insects or disease risk is a worry on a specific trip, it’s worth checking current local health advice too.

Common Questions
What is the most effective insect repellent?
For skin, repellents based on DEET or picaridin are the most reliable and longest-lasting, and picaridin has the edge for comfort because it is not greasy and does not damage plastics and synthetics. For clothing, permethrin is in a class of its own, repelling and killing insects that land on treated fabric. Used together, a skin repellent and treated clothing cover far more than either alone, which is why the best approach combines them.
Do citronella candles and wristbands work?
Not well enough to rely on. Citronella candles create only a weak, very localised effect that a breeze disperses, and repellent wristbands and ultrasonic devices have repeatedly failed to protect the skin beyond a few centimetres from the device. They are not entirely useless as a mild background measure, but treating them as your main defence is how people end up covered in bites. Put your trust in proven skin repellents, treated clothing and physical barriers instead.
Is permethrin safe to use on clothing?
Yes, when used as directed. Permethrin is made to be applied to fabric rather than skin, and once it has dried on the clothing it is bound in and safe to wear, continuing to work through several washes. Treat the garments at home, let them dry completely before wearing, and keep the wet product away from cats during application, as they are sensitive to it until it dries. Applied properly, it is one of the most effective layers you can add.
