For use on clothing, tents, and other gear, Sawyer Permethrin not only repels insects, but actually kills ticks, mosquitoes, chiggers, mites, and more than 55 other kinds of insects on contact. The active ingredient Permethrin is a synthetic molecule similar to pyrethrum which is taken from the Chrysanthemum flower.
Permethrin is odorless after drying and will not stain or damage clothing, fabrics, plastics, finished surfaces, or any of your outdoor gear. A single application lasts 6 washings or 42 days of sun exposure.

Will Permethrin ruin my clothes or equipment?
No. Permethrin will not damage clothes or equipment. Unlike DEET, which may harm some fabrics and materials, Permethrin is compatible for use even on fragile fabrics such as silk, plus all synthetics and waterproof membrane fabrics. Permethrin will not affect plastics or finishes. IF IN DOUBT, try a sample on an obscure surface area, especially on delicates and check it after 24 hours of exposure.
Sawyer® Permethrin Insect Repellent is odorless, non-greasy and non-staining after it dries. Permethrin can be harmful to aquatic creatures such as fish, so do not spray Permethrin around fish aquariums.
How do I use Permethrin safely?
Permethrin is to be applied to clothing and material. It works by bonding to the fibers. When a tick or other insect comes into contact with the Permethrin, it absorbs a dose that will either repel or kill the insect. You apply Permethrin using an aerosol or trigger spray until the fabric is damp and then allow it to dry. Permethrin is easy to use and the resulting layer of protection is very important to your safety from insect-borne diseases.
How long does Permethrin last?
At the concentration level delivered in the aerosol, non-aerosol pump sprays and soak systems (all at 0.5% Permethrin), an application lasts for six weeks and through six washings. Permethrin breaks down through exposure to air (oxygen) and sunlight (ultraviolet light). If you store the clothes in black plastic bags between uses, you can extend the time of effectiveness; however, always retreat after the sixth laundering. Permethrin may also be used on sleeping bags, tents and nettings.
Does Permethrin work against mosquitoes?
Yes. Permethrin clothing treatments, when applied following Directions for Use, have been determined to have “spatial repellency” against mosquitoes. This means that mosquitoes will swarm around you, but not light on your treated clothing and bite.
Also use an EPA registered repellent, such as the Sawyer® microencapsulated Controlled Release 20% DEET, on all exposed skin for further protection from biting and blood sucking mosquitoes.
The combination of Permethrin on clothing and DEET repellent on skin forms an “Insect Repellent System.” When used as directed on the EPA registered labels, the Insect Repellent System will provide the best protection from biting, blood sucking and disease carrying insects. A well known study conducted by Tom Lillie, Carl Schreck and A. J. Rahe in Alaska in 1987, showed 99.9% effectiveness against mosquitoes biting at a rate of more than 1,100/hr. This protection is far greater than either a DEET based insect repellent or Permethrin can achieve alone.
Does Permethrin work against bed-bugs?
An area bomb, which fumigates the room as a whole, is usually recommended as the first line of defense against bed bugs. As you may not be in a position to bug bomb your hotel room while traveling abroad (without offending the natives), the following uses for Permethrin may help:
Spray treat at least the upper surfaces of your mattress when you first arrive, with 0.5% Sawyer Permethrin Insect Repellent. Permethrin pump sprays are preferred because they are not restricted for airline travel. Allow the mattress to dry and air out before using it. Cover with a clean sheet for sleeping; do not sleep directly on the treated mattress. If you are concerned about the pillows, uncover them and lightly spray treat them with Permethrin also, re-covering them before use. Use 0.5% Permethrin spray as a residual surface insecticide for cracks and crevices around the room, and as a light spray on stuffed furniture, carpeting, and other fabrics around your sleeping quarters, where bed bugs and other crawling insects may hide.
Some of the information on bed-bugs was extrapolated from Maine University’s Pest Management’s Fact Sheet on Bed-Bugs at http://pmo.umext.maine.edu/factsht/bedbugs.htm.
Can Permethrin cause irritation or sensitization from repeated use?
Studies in animals have demonstrated that no skin irritation or sensitization is expected following direct application. In a controlled human study, permethrin did not cause significant skin irritation or sensitization when tested in 200 subjects. No significant skin effects are expected from wearing permethrin-treated clothing.
