What to Spray With Permethrin Before Your Next Camping Trip
People often think to treat their clothing with permethrin spray, but footwear, tents, packs, and even camp chairs can also benefit from permethrin’s tick and mosquito protection. This guide covers exactly which items to spray, what to avoid, how to apply permethrin correctly, and how long you can expect the treatment to last.
Quick Answer
Before a camping trip, prioritize treating clothing, shoes and boots, socks and gaiters, backpacks, tents, hammocks, and other fabric camp gear with permethrin. Apply according to the product label, allow everything to dry completely before use, and use a topical repellent such as picaridin or DEET on exposed skin.
What Permethrin Is and Why It Works On Clothing and Gear
Permethrin is a synthetic insecticide you spray on clothing, shoes, tents, backpacks, and other outdoor gear. Because permethrin has the power to repel and kill ticks, mosquitoes, chiggers, flies, and fleas on contact, it is often considered one of the most effective insect repellents for clothing and gear.
What makes permethrin different from skin repellents like DEET or picaridin is how it works. When an insect lands on treated fabric, the permethrin disrupts its nervous system. Bugs don't just avoid the fabric; they may be knocked down if they touch it.
The CDC recommends permethrin-treated clothing specifically for tick prevention, and the EPA has registered it for use on fabric since 2003.

What to Spray With Permethrin for Tick and Mosquito Protection
Permethrin spray can be used on many types of camping gear and clothing, including cotton, nylon, and polyester. The goal of using permethrin to treat camping gear and clothing is to create a barrier between you and the insects most likely to bite.
Tents, Hammocks, and Mosquito Nets
Treating shelter fabric helps keep insects away at the campsite. Tents and hammocks are all good candidates. In mosquito-heavy areas, treated mosquito nets make a noticeable difference when sleeping in a hammock under the stars.
Camp Chairs, Blankets, and Travel Sheets
Stationary gear often gets overlooked. A permethrin-treated blanket or camp chair helps keep biting midges and mosquitoes away during evening hours when they're most active.
Travel sheets are useful for camping trips to regions with mosquito-borne diseases. They add a treated layer between you and potentially untreated bedding.
Backpacks and Daypacks
Your pack can brush against vegetation throughout the trail, creating another potential point of contact with ticks. The shoulder straps and hip belt are particularly worth treating since they contact your clothing directly. The main body of the pack benefits too, especially if you set it down in grass or lean it against trees during breaks for food or sightseeing.
Hats, Bandanas, and Neck Gaiters
Mosquitoes and biting flies often target the head and neck. If you plan to camp in a mosquito-prone area, treating your hat or bandana helps protect those areas so you can enjoy hikes and sitting around a campfire. Permethrin-treated bandanas can also be worn around the wrist to cover hands and forearms. Neck gaiters cover the neck and can be pulled up over the face when bugs are heavy.
Shirts, Pants, and Base Layers
Long-sleeved shirts, pants, and base layers are all excellent candidates for permethrin spray. In tall grass, wooded trails, or brushy areas, treated clothing helps create a protective barrier between you and ticks and mosquitoes. Lightweight hiking shirts, convertible pants, and moisture-wicking base layers are all commonly treated before camping trips.
Shoes, Boots, Socks, and Gaiters
Hiking boots, trail runners, rubber boots, and other shoes you plan to bring camping can all benefit from a permethrin spray treatment. Ticks typically attach at ankle level, then crawl upward. That makes treating boot gaiters and making sure you have insect-repellent socks before your next trip a high priority.
| Item Category | Examples | Why It Matters |
|---|---|---|
| Clothing | Shirts, pants, base layers | Full-body barrier against ticks and mosquitoes |
| Footwear | Socks, boots, gaiters | Ticks attach at ground level |
| Head and neck | Hats, bandanas, neck gaiters | Protects from flying insects |
| Packs | Backpacks, daypacks | Brushes against vegetation |
| Shelter | Tents, hammocks, mosquito nets | Campsite insect protection |
| Camp gear | Chairs, blankets, travel sheets | Evening and stationary use |
What Not to Spray with Permethrin
Permethrin is safe when used as directed, but there are clear boundaries on where it belongs.
- Do not apply permethrin directly to skin. Use it only on clothing, footwear, and gear as directed by the product label. For exposed skin, use a complementary repellent like picaridin or DEET. The combination of treated clothing plus a skin repellent gives you layered protection.
- Keep permethrin away from anything used for eating or drinking, and avoid spraying near streams, lakes, ponds, or other bodies of water.
How to Apply Permethrin Spray to Clothing and Gear
The application process is straightforward:
Spray Outdoors
Spray outdoors in a well-ventilated area.
Apply Evenly
Apply an even coat to the recommended surfaces.
Let It Dry
Allow items to dry completely before use.
Follow the Label

Common Mistakes to Avoid
- Waiting until the morning of your trip to treat your clothing and camping gear.
- Forgetting to treat boots and backpacks, leaving gaps in your protection.
- Spraying skin with permethrin instead of clothing.
- Packing items before they're dry.
How Long Does Permethrin Spray Last After Application?
Insect Shield’s DIY Permethrin Spray typically lasts through 6 washes or 60 days before you need to reapply. It’s a great option for camping gear or clothing you want to quickly treat yourself.
If you are looking for a longer-lasting option, consider Insect Shield's EPA-registered pre-treated gear. Insect protection on hats, bandanas, socks, pants, and more lasts the expected lifetime of the garment (up to 70 washes for apparel).
- DIY spray treatment: Lasts up to 6 washes or 60 days before reapplication.
- Factory pre-treated clothing: Long-lasting protection through the expected lifetime of the garment, up to 70 washes for apparel.
Is Permethrin Safe for Families and Pets?
Permethrin has been registered by the EPA for use on clothing since 2003. The U.S. military treats combat uniforms with permethrin, and permethrin-treated clothing and gear can be used by families when product directions are followed.
Allow treated items to dry completely before wearing or handling them. Wet permethrin can be hazardous to cats, which is why outdoor application, keeping pets away during treatment, and complete drying are important.
Spray or Buy Pre-Treated Clothing?
You have three primary options for getting permethrin onto your gear before your next camping trip. Each fits different situations.
| Method | Best For | Duration | Effort Level |
|---|---|---|---|
| DIY spray | Shoes, packs, tents, trip-specific items | Up to 6 washes or 60 days | Medium |
| Factory pre-treated | Everyday outdoor clothing | Lifetime of garment, up to 70 washes for apparel | None |
| Professional send-in | Favorite clothes you already own | Long-lasting professional treatment | Low |

The most reliable protection comes from layering: treated clothing on your body, treated gear around you, and a skin-applied repellent on exposed areas.
Start with the items closest to where ticks and mosquitoes make contact. Socks, pants, and boots handle ground-level threats. A treated shirt and hat cover your upper body. Plan to spray your pack and shelter for full coverage on overnight camping trips.

Can you spray permethrin on leather hiking boots?
Permethrin spray can be used on many types of hiking boots and other footwear to help protect against ticks. If your boots are made from finished, polished, or specialty leather, check the product label and test a small, inconspicuous area first.
How far in advance of a trip should I treat my clothing and gear?
Treating clothing and gear at least one to two days before your trip gives you plenty of time for items to dry completely. Always follow the product label and do not use treated items until they are fully dry.
Does permethrin wash off in rain or sweat?
Permethrin binds to treated fabric, so ordinary rain and sweat are not the same as laundering the item. Washing gradually reduces the effectiveness of a DIY treatment, which is why reapplication is needed according to the product label.
Can I use permethrin spray on tents, hammocks, backpacks, and camp furniture?
Yes. Permethrin spray can be used on a range of clothing and gear, including many tents, hammocks, backpacks, and fabric camp items. Check the product label before use to confirm that your intended item is a documented use case.
