1, environmental governance. The life of flies is also divided into four periods: egg, larva, pupa and adult. The first three periods mainly live in breeding grounds and breeding grounds. A large number of wastes produced in human life or production, such as food residues, excreta, secretions, production leftovers, etc. Are good breeding grounds for flies, so controlling the breeding grounds of flies is the key to prevention and control.
2, drugs to kill flies. (1) pesticide application on the retention surface: spray pesticides with residual effect and contact killing effect on the surface of fly litter, indoor walls and roofs more than 2 meters. Generally, the surface with strong water absorption should be coated with low concentration and high dose, and the surface with poor water absorption should be coated with high concentration and low dose. (2) Space spraying: it can kill adult flies quickly, but the duration is short, because adult flies can only be poisoned and die after contacting the sprayed fog particles. Commercially available aerosols and sprays are generally only used for space spraying because of their high prices. When spraying, the nozzle should face upwards, not towards the ground. Adult flies can be killed or caught by hanging with poisonous fly rope, laying fly bait, sticking fly paper and catching fly cages. Experts in Ivy's office said that the best way to kill flies is that flies are completely abnormal insects, and they will go through three periods in their lives, including eggs, larvae (maggots) and pupae. Therefore, the best way to kill flies is to deal with substances suitable for fly breeding. If the garbage is bagged (the bag should be intact and the bag mouth should be tightly tied), do not litter or urinate anywhere, and properly handle the pet feces.
