Sawyer Permethrin Clothing & Gear Insect Repellent Spray, Twin 12 oz — Long‑Lasting 6‑Week Protection

This ready-to-use trigger spray is designed to add an odorless, long-lasting layer of protection to outerwear and equipment used while camping, hiking, hunting, or traveling. The formula adheres to fabric fibers and remains active through sweat and light moisture; it eventually breaks down from sunlight or machine agitation. Use it on shirts, pants, socks, shoes, sleeping bags, tents and netting to reduce the chance insects make contact with treated surfaces.

How should I apply Sawyer Permethrin to clothing and camping gear?

Apply the spray outdoors or in a well-ventilated area. Hold the bottle about 6–8 inches from the fabric and use slow, sweeping strokes so both sides of each item receive even coverage; treat each side for roughly 30 seconds per garment.

• Treat shirts, pants and socks with about 4.5 ounces per outfit as recommended by EPA guidance.
• Spray tents, sleeping bags and netting thoroughly and allow to dry completely before packing or sleeping on them.
• Allow treated garments to air dry fully; the product becomes odorless when dry.

How long does the protection last and what reduces its effectiveness?

Sawyer Permethrin bonds to fibers and stays active for up to 42 days of sun exposure or through six wash cycles, whichever comes first. The spray resists removal by sweat or rain but will gradually degrade when exposed to ultraviolet light or machine agitation during laundering.

• Protection duration: up to 6 weeks or 6 washings.
• Resists sweat and light water contact; avoid excessive UV or frequent machine washing to preserve efficacy.
• Reapply as needed after heavy washing, long sunlight exposure, or before extended outdoor trips.

What insects does it reduce contact with and is there research supporting its use?

The spray is labeled to reduce or eliminate contact with more than 55 insect species commonly encountered outdoors, including ticks and several mosquito types associated with disease transmission. A University of Rhode Island study found treating footwear significantly lowered tick bite risk, highlighting practical benefits of fabric treatments.

• Effective against ticks, mosquitoes, chiggers, mites, spiders and other listed pests.
• University of Rhode Island (2017) reported substantially fewer tick bites on treated footwear.
• Using treated gear can reduce insects in campsite areas and limit attachments to clothing.

Can Sawyer Permethrin damage clothes or interact with other gear?

The formula is designed not to stain or harm fabrics, plastics, finished surfaces or most outdoor equipment when applied as directed. It dries odorless and is formulated for compatibility with common outdoor materials; always test on a small area if concerned about delicate fabrics or finishes.

• Non-staining and safe for most clothing and gear when used according to instructions.
• Does not wash out with sweat or water contact; degrades mainly from UV or vigorous machine washing.
• Pair with a topical skin repellent (for example, Picaridin) for layered protection.

Who is this for: Ideal for campers, backpackers, hunters, travelers and anyone spending extended time outdoors who wants a durable, fabric-focused insect protection option. It’s suited to people who prefer treating clothing and gear rather than relying solely on skin-applied repellents, and for those who want to reduce insects around sleeping and camp areas.
