For use on clothing, tents, sleeping bags, and other outdoor gear, Sawyer Permethrin repels or kills disease-spreading ticks (Lyme disease), mosquitoes (West Nile and Zika viruses) and more than 55 other kinds of insects. Perfect for camping, backpacking, hunting, travel, backyard BBQs, picnics, and more, Permethrin insect and tick repellent adds an odorless layer of protection to shirts, jackets, pants, socks, shoes, sleeping bags, tents, netting, and other outdoor, camping, hunting, and travel gear. Specially formulated not to stain or damage your clothing, other fabrics, gear, and equipment, it's odorless after drying and is as effective as 100% DEET. To apply, spray Permethrin directly onto clothing and gear with a slow sweeping motion, keeping the bottle about 6 to 8 inches away, and treating each side of the garment for about 30 seconds. Permethrin spray bonds to fabric fibers for up to 6 weeks (42 days) of exposure to sun and air or 6 washings.
