Hot smoke treatment: Spray the smoke into the kitchen at a dose of 1520mgal/mZ, and seal the doors and windows. According to the actual space of the room, combined with the flow of the smoke machine, the time of the smoke is determined, and the smoke overflow is minimized when the smoke is sprayed. In the same way, after 40 days, the treatment was repeated, and the number of escapes and deaths was recorded. 4 people food unit sputum area a total of 45o0m2. After observation, except for a small number of American cockroaches found in the hospital's kitchen, the rest of the place is breeding in Germany. After two times of smog smog, the food units achieved good cockroaching effect. The average density decreased from 2071/smin before the extinction to 3/5 min after 40 days, and the density decline rate reached 9.85%. (test results). Propoxur is a non-systemic and moderately toxic pesticide with contact, stomach and smoldering effects, and has the characteristics of fast knockdown, long residual effect, no phytotoxicity and wide spectrum of insecticides. After two consecutive application, the cockroaches escaped, and the number of nymphs increased significantly, revealing that the eggs in the application gap hatched into nymphs, which proved that the heat of Beitan heat had no killing effect on the egg sheath. Therefore, before the extinction, the ecological population of the dominant population to be controlled by the environment should be investigated, and the average egg stage and nymphal stage in different environments and temperatures should be accurately grasped. The interval between application should be shorter than the average nymphal stage, and continuous application should be continued. The total interval should be longer than the average egg period to achieve high-efficiency, long-term control of sputum density; if the purpose of emergency control density is simple, each application interval should be determined according to specific requirements, such as 1/3 egg stage Apply a drug to Sichuan. The use of hot smoke drug-loading technology to control cockroaches has the advantages of high efficacy, economical use, and ease of use. The shortcoming is that the smoke is relatively large, and all the personnel need to be withdrawn before the cockroach is destroyed, which affects the normal work of the personnel. At the same time, it is more troublesome in hotels and restaurants equipped with automatic sprinklers, especially the hot smoke machine is noisy, which is easy to cause people to be disgusted. Therefore, when multiple environments coexist, multiple methods of mites should be used simultaneously to achieve better mites. UV intensity test results detected 5 kindergartens using 5 UV tubes, qualified 31, the pass rate was 68.89%. At the same time, the number of indoor UV lamps installed was only 3 kindergartens, and the rest did not reach 1.suw/n13. Claim.
