How to prevent and control the four pests

1. Flight control: 1. Do a good job in environmental sanitation and keep the environment clean. \x0d\2。 Garbage will be cleaned up every day, and garbage from special industries must be disposed of in time. \x0d\3。 Harmless treatment of feces, popularization of harmless toilets, and sealing of septic tank cover. \x0d\4。 For propagation materials that can't be completely removed in time, use organophosphorus pesticides to kill larvae, and treat them once every 5-7 days in summer and autumn, and once every 10~ 12 days in winter and spring. \x0d\5。 Kill flies in some important places by chemical or physical methods. Such as detention spraying, space spraying, artificial flapping and use of sticky fly paper, fly-killing lamp, poisonous fly rope, fly trap, etc. \x0d\ II。 Prevention and control of rodents: Common rodent control methods include instrument rodent control and drug rodent control, such as mousetrap and mousetrap. Commonly used drugs include diphacinone sodium salt, zinc phosphide, Daryun, etc. It must be noted that rodent control requires a total annihilation war and a protracted war, and it is best to use various methods alternately. \x0d\ Precautions for killing rats with poison bait: 1. Put a little poison bait and pile it up. If rats are found stealing food, they should be supplemented in time, and they should be supplemented twice after eating until they stop stealing food; 2. Poison bait should be placed against the wall, rat path, rat hole and other hidden places; Put it in a dry and waterless place. We must stop eating rat food and close livestock; 4. Clean up the environment and clean up the dead rats in time after administration. Use chronic rodenticide according to national regulations. If you want to use acute rodenticide, you should have professional guidance. \x0d\ III。 Mosquito control: to eliminate mosquitoes, we must fundamentally solve the problem, that is, eliminate mosquito breeding grounds, supplemented by killing larvae to control the occurrence of mosquitoes. Mosquito-repellent incense, mosquito-repellent paper and electric mosquito-repellent incense can be used in summer, and mosquito nets, screen doors and screens can be placed indoors to effectively prevent mosquito bites. \x0d\ 1。 Remove all kinds of accumulated water and eliminate mosquito breeding conditions: \ x0d \( 1) dredge and remove accumulated water; \ x0d \(2) Filling depressions, sewage pools and tree holes; \ x0d \(3) seal the pool, water tank and sewer; \ x0d \(4) For useful water storage and potted plants, change the water regularly 1~2 times a week, or take measures such as pesticide control, stocking fish and sealing. \x0d\2。 Use chemical pesticides and other methods to kill larvae and adults. \x0d\ IV。 Cockroach control: To eliminate cockroaches, Qi Xin must work together to take measures that pay equal attention to environmental control and chemical control. Methods Eggs were killed by boiling water, drugs were sprayed or painted with poison bait and medicine chalk. It is best to act at night, because cockroaches like dim light. \ x0d \( 1) For the mixed, chaotic, broken and dirty environment, "three cleanups and one wall" (cleaning up sundries, ovaries, cockroaches' tracks and blocking the cracks in the wall) should be achieved to reduce the places where cockroaches breed and live. \ x0d \(2) Poison bait, medicine pen sealing, residual spraying and powder spraying are used to kill cockroaches. \x0d\ The main drugs except "four pests" are as follows: \x0d\ Rodenticide: bromadiolone, Daryun, diphacinone sodium salt, etc. \x0d\ fly killing: organophosphorus, pyrethroids, etc. \x0d\ Mosquito control: The adults are organophosphorus and pyrethroids. Mosquitoes include Bacillus thuringiensis-14, bacillus sphaericus, etc. \x0d\ cockroach killing: organophosphorus, pyrethroids, etc. \x0d\ The rodenticides prohibited by the state are: sodium fluoroacetate, fluoroacetamide, tetramine (424), glycollate, etc. The reason is that these drugs have strong toxicity, acute onset, severe symptoms, irreversibility, slow natural degradation and easy to cause secondary poisoning. \x0d\ Related background: The harm of "four pests" should not be underestimated \x0d\ Mosquito: It bites human skin through its sharp and thin mouth. Mosquitoes will also inject saliva into the human body when they suck blood, thus spreading diseases, such as malaria, filariasis and Japanese encephalitis. \x0d\ Fly: The surface of houseflies can adhere to more than 65,438+07 million. Flies mainly pollute food and water through feces, which causes people to get sick. Some flies can bite people and livestock, while others lay eggs on human anus, vagina and suppurative wounds, resulting in maggot disease. \x0d\ Mouse: It not only wastes food and destroys things, but also spreads many diseases, such as plague, typhus, forest encephalitis and hemorrhagic fever. \x0d\ Cockroaches: They live in dirty places, but sometimes they run into beautiful houses. Cockroaches carry a variety of germs and produce unpleasant secretions, which destroy the taste of food. Studies have shown that sensitive people will have allergic reactions if they come into contact with food or dust contaminated by cockroaches.
