Wear plastic gloves and dip your outer garments in the solution in a large plastic storage bin. Hang wet clothes until air dry. Solution maybe a slight irratint to some but safe when dry. Don't dispose of solution in any ponds or waterways because it kills water species. Effective for about six washings. Military contract issue BDUs are woven from thread saturated in Permethrin.
