These bugs appear on the top of the wall, which may be caused by the humid weather in the south. What pesticides are there?

Generally speaking, the methods and measures to control insects are: keeping the environment clean and tidy; Keep pets clean and hygienic; Spraying pesticides in space; Smoked to death; Indoor spray stagnation, etc. Ordinary families should be vigilant when buying and using pesticides. First of all, they should use them sparingly, but they should not use them when they are not in use. Secondly, leave the scene immediately after spraying pesticides. After half an hour, open the window and fully ventilate before entering the room. Thirdly, infants and children with poor brain development must not be exposed to any pesticides to avoid adverse effects on brain development. In addition, the use of pesticides in the kitchen should not pollute food and cookers. Because most insecticidal aerosols are flammable, they should not be used in the kitchen, because open flames are used in the kitchen to avoid fires. Among pyrethroid insecticides, cypermethrin (Kung Fu) and deltamethrin (Kesuling) have strong contact toxicity and stomach toxicity, and their efficacy is fast and lasting. Easy to use, directly diluted with water, can give full play to the drug effect, has good dispersibility, is safe to animals, has no irritating smell, and has no corrosive damage to the surface of objects. Deltamethrin also has certain ovicidal effect. Among organophosphorus pesticides, chlorpyrifos is a kind of drug with good control effect on health pests. When chlorpyrifos EC is diluted and sprayed, it has a high contact killing effect on insects. Although dichlorvos is highly toxic to people and animals and corrosive to the surface of copper and iron products, it can be used properly in indoor large-scale pest control because of its characteristics of fast knocking down and strong fumigation, and its price is low. When spraying chemicals, it is most important to choose dosage form, concentration ratio and correct use method according to the actual situation. In addition, operators should pay attention to safety and wear protective clothing, hats, masks and gloves.
