Abstract: Health insecticide coating type WS-I was shown to have very strong knockdown and cidal effect on mosquitoes, flies and cockroachs. When these insects examined came into contact with the treated surface which had been coated two years for 1-3 hours, a death rate of 100% could be found. The main criteria (KT50, 24 hr rate of death) of WS-I have an advantage over that of international similar products (Artilin). The releasing experiments of mimic testing under normal temperature showed that KT50 of Culex pipiens pollens was within 5.6-40.3 minutes, while that of Musca domestica within 10.4-26.4 minutes. The 24 hours' killing effect for both the mosquitoes and the flies was 100%. It is harmless to humans and domestic animals. The coating is stable and cost less.
