The surface tension of washing powder is very large, as long as there are many small holes in the abdomen of cockroaches, but these small holes are really the main tools for cockroaches to breathe air. When we spray wine on cockroaches with washing powder mixed with water, the washing powder water will quickly enter their breathing holes, causing cockroaches to block their pores and make them unable to breathe. In addition, the ingredients of washing powder are acidic and alkaline, and its chemical properties constantly react in cockroaches, which will instantly suffocate cockroaches and kill them, and cockroaches will fall to the ground.
A more effective and convenient method is to sprinkle washing powder on the places where cockroaches may haunt, and eating washing powder will kill you. Because washing powder is an efficient agent for trapping and killing cockroaches, its effect is even better than some chemical pesticides. Or according to the ratio of 1: 4, dissolve soap in hot water and spray it directly on cockroaches with hot soapy water, which can effectively kill cockroaches.
