Have cockroaches in Guangdong "evolved"? This speculation is unscientific!

According to Guangdong Radio and Television Station, recently, Foshan Center for Disease Control and Prevention released an article on the "German cockroach resistance experiment results", which pointed out that German cockroaches have become resistant to two insecticides. Some netizens believe that this shows that "cockroaches have evolved."

A staff member of Foshan CDC said that the speculation that "cockroaches have evolved" is unscientific . Low-level resistance means that cockroaches are resistant to insecticides, but not too strong, and the dosage can be increased appropriately when used. The disinfection and vector control staff of Foshan CDC said that the method of using insecticides to eliminate cockroaches is actually a temporary solution, not a permanent solution. It is recommended to solve the problem from the root, remove the cockroaches' habitats and activity areas, and cut off their food sources.

In this regard, netizens have said: "It is true" and "It is not considered evolution if the resistance to slippers has not evolved"↓↓↓

Cockroaches are very common pests in our daily lives. Zhou Xiaomei, an expert at the Disinfection and Vector Research Institute of Yunnan Provincial Center for Disease Control and Prevention, said that cockroaches have amazing reproductive capacity and superb ability to adapt to the environment. They eat a wide range of food, including garbage, feces, bread, books, fur, Chinese medicinal materials, soap, etc., and they like dark, warm and humid places.

Related studies have shown that cockroaches carry 40 to 50 pathogenic bacteria, including Shigella dysenteriae, pathogenic Escherichia coli, plague bacillus, hepatitis virus, pneumonia virus, etc. If people come into contact with food or dust contaminated by cockroaches, they may suffer from allergies at the mildest, or even gastroenteritis, dysentery, hepatitis, pneumonia, etc. Therefore, once cockroaches appear in your home, it is best to kill them in time.

Li Yanzhong, an expert from the Disinfection and Vector Research Institute of Yunnan Provincial Center for Disease Control and Prevention, reminded that the first step is to minimize the breeding and habitat of cockroaches through environmental treatment and management. For example, use mortar or silicone to smooth the gaps and holes in the kitchen and bathroom to ensure that there are no passages for cockroaches to enter the house and no hiding places for cockroaches in the house.

Food boxes and packaging boxes used when shopping, express parcels received, cartons and suitcases brought back from outings, etc. should be carefully checked before entering the house to see if there are hidden cockroaches or attached egg cases to prevent cockroaches from "hitchhiking" into the house.

Pay attention to the cleanliness of the kitchen and bathroom to prevent water accumulation. Carry out general cleaning regularly, and thoroughly clean the cabinets where food is stored, under the refrigerator, and places where sundries are piled up; unused waste such as waste paper boxes, cartons, plastic bags, etc. should be removed in time; once cockroach egg cases are found, they should be crushed or burned to prevent cockroaches from spreading in the home.

When killing cockroaches, you can also use special chemical insecticides, such as cockroach aerosol, cockroach glue bait, cockroach poison bait, etc. Among them, cockroach glue bait can be applied in spots to places where cockroaches often appear and hide. Because of its environmental protection, safety and convenience, it is widely used in homes, offices and supermarkets to kill cockroaches. In addition, using powders, cockroach houses, cockroach sticky paper and other methods can also kill indoor cockroaches.
