      What are the dangers of "four pests" to human beings?
      1. Mice
      Rats can transmit plague, epidemic hemorrhagic fever, leptospirosis, and many other diseases. We should do a good job in environmental hygiene, reduce the hiding place of mice; collect good food, reduce the pollution of mice to food. Catching and killing mice can be used with rat traps, cages, sticky rat board and other tools, but also the use of safe and efficient drug rodent control. Attention should be paid to the storage and use of rodenticide to prevent human and animal poisoning.
      2. Mosquitoes
      Mosquitoes can spread malaria, encephalitis, dengue fever and other diseases. We should do well in environmental hygiene and eliminate mosquito breeding grounds. According to the situation, screen doors, screens, mosquito nets, mosquito incense, insecticides and other mosquito control supplies to prevent mosquito bites.
      3. Cockroaches
      Cockroaches can spread diseases such as dysentery and typhoid fever, and their excreta proteins can also cause allergic rhinitis and asthma. Most cockroaches live in humid environments, so keeping the room dry and clean can reduce the breeding of cockroaches. After the meal, keep the food in a sealed storage, wash the dishes with hot water, keep the stove clean, and clean the garbage on the ground and in the garbage bags in time. Cockroaches can be killed by using drugs or cockroach sticky boards.
      4. Flies
      Flies can spread diseases such as cholera, dysentery, typhoid fever and so on. The effective way to control flies is to deal with the breeding environment of flies, such as garbage bagging (bags should be intact and unbreakable, bags should be tightly tied), not litter, do not defecate anywhere, handle pet excrement and so on. It is important to keep good food and prevent flies from crawling, so as not to infect diseases. Killing flies can use fly swatter, fly killing lamp, sticky fly paper (tape, rope) and so on.
