Sawyer Permethrin is a trigger-spray treatment for clothing and gear, not for skin. You spray shirts, pants, socks, shoes, tents and sleeping bags, and it bonds to the fabric to repel and kill ticks, mosquitoes, chiggers, spiders and mites. It lasts up to six weeks of sun and air exposure or six washings, and it is odorless once dry and won't stain fabrics or gear. It suits campers, hikers, hunters and travelers who want protection built into their gear; it is not a substitute for a skin repellent, so Sawyer pairs it with its Picaridin spray.

Buyers rate it highly and mostly talk about how well it works on clothing and gear for camping and tick-heavy areas. Complaints center on the sprayer and on how quickly a bottle goes when treating several outfits.
Sawyer Permethrin Clothing and Gear Insect Repellent is a trigger spray for treating clothing, tents, sleeping bags, netting and other outdoor gear. It repels or kills ticks, mosquitoes, chiggers, spiders, mites and more than 55 other kinds of insects. It is fragrance free and odorless after drying.
The spray bonds to fabric fibers and lasts up to 6 weeks (42 days) of exposure to sun and air, or through 6 washings, whichever comes first. It is formulated not to stain or damage clothing, fabrics, plastics, finished surfaces or gear. It stays effective despite sweat or water, and breaks down with UV exposure or washing machine agitation.
To apply, spray directly onto clothing and gear with a slow sweeping motion. Hold the bottle about 6 to 8 inches away and treat each side of the garment for about 30 seconds. The EPA recommends 4.5 ounces to treat one outfit of shirt, pants and socks. A 2017 University of Rhode Island study found that people wearing permethrin-treated shoes and socks were 73.6 times less likely to have a tick bite than those wearing untreated footwear.
