Can permethrin SFR 36.8%,diluted to 0.5% be used to treat cloths for tick control?
Permethrin SFR 36.8% cannot be used on clothing of any type. We do carry Tick Block which was specifically manufactured for use on clothing for tick control. While Tick Block and Permethrin SFR 36.8% share the same active ingredient the base ingredients are very different and the products are not interchangeable.
