Objective To test the killing effect of four kinds of retention spray on house flies and American cockroaches. Methods According to the Pesticide Registration Pesticide Efficacy Test and Evaluation Part 1 propellant (GB / T 13917.1-2009), 4.5% beta-cypermethrin, 5% alpha-cypermethrin, 10% alpha-cypermethrin and 20% Indoor stagnant spraying and killing cockroaches efficacy test. Results The lethal effects of 4.5% homoclimate, 5% homoclimate and 10% cypermethrin on flies and American cockroach were better in the four kinds of residual spraying agents, and the mortality rate could be within the prescribed test days 95% and above, longer duration, 20% lethal effect on flies and cockroaches in the United States slightly less lethal and shorter sustainable days. Conclusion The four kinds of retention spraying agents have good control effects on flies and American cockroaches.
