Cockroaches are common sanitary pests, widely distributed in tropical and subtropical regions and have very strong viability and reproductive capacity. Cockroaches are infected and swallowed by many pathogens because they prefer to crawl everywhere and do not eat. Research results show that the cockroach can artificially infect bacteria causing diseases such as Asia cholera, pneumonia, diphtheria, gangrene, anthrax, tuberculosis and the like. Therefore, in order to improve the living hygiene level of residents, a large number of products for preventing and treating cockroaches appear on the market, and the test methods of the products are all in accordance with national standards such as GB/T13917.10-2009 or GB/T27783-.
