We can drive away cockroaches with soapy water, cut the bottom of a mineral water bottle into a container the size of disposable cups with scissors, or directly use disposable cups, fill it with clear water, cut some soap in the cup, stir until the soap is completely melted, and then put it in the corner where cockroaches breed. Onions can also drive away cockroaches. We cut onions and soak them in water, then sprinkle the water soaked with onions on the place where cockroaches appear, or directly cut onions and put them in a bowl where cockroaches can be found.
As long as the environment is dirty and dirty, cockroaches will surely run wild there. Therefore, improving health and environmental management is the fundamental measure. In order to kill indoor cockroaches, we must first do a good job in hygiene, eliminate the habitat conditions of cockroaches, and extensively carry out activities such as plugging holes, wiping seams and "eight inspections" to eliminate the egg sheaths and cockroach traces in cockroach habitats. The footprints of cockroaches refer to insect carcasses, residual limbs, corpses, wings, molting, cockroach excrement, empty egg sheaths and so on. Cockroaches often drill into cracks and bunkers, so when spraying with a sprayer, they must be sprayed into cracks.
Because cockroaches are everywhere, we can buy drugs to kill them. When we distribute medicine, we should distribute medicine in restaurants, living rooms, bedrooms and other places at home, as well as drawers, cabinets and corners of cabinets, so as to ensure that cockroaches can be attracted to take medicine wherever they go.
