Matt, permethrin is the active chemical..put on clothes ONLY and dry completely before wearing..ticks and redbugs won't make it more than a few inches crawling on it...it is used to treat livestock for external parasites...don't know what the adverse affect on humans is, if any. Be sure to treat any seat cushion as well as boots and hat...ticks are a thing of the past if you use it according to directions. Some outlets have quit carrying it because of people not reading directions and putting it on bare skin like regular bug juice.
