Lasts for 6 Weeks or 6 Washes
Unlike topical insect repellents applied to the skin, Permethrin is applied to clothing and outdoor gear material, bonding to the fabric fibers for up to 6 weeks (42 days) or 6 washings.
When a tick, mosquito, or other insect comes into contact with Permethrin, it absorbs a dose that will either repel or kill the insect. The synthetic version of pyrethrum (a natural insecticide derived from the chrysanthemum flower), Permethrin is non-toxic and registered for use by the U.S. EPA.
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.
