PT Wasp Freeze II Aerosol is the only product needed to instantly knock down and kill bees, hornets, yellowjackets, spiders (including black widow and brown recluse), and wasps. Knock down is so fast, the stinging pheromone of the insect doesn’t have time to be released, which reduces the possibility of being stung. Designed with the safety of the applicator in mind, the spray can travel up to 15 feet. In addition to the fast-acting, knock-down power, the residual activity of the active ingredient, Prallethrin 0.1, ensures complete elimination of the nest. PT Wasp Freeze II can be used outdoors and in attics and crawlspaces only.
