Buy some pesticides and spray them wildly, close the doors and windows and smoke them to death. Check dry goods, rice noodles, snacks, etc. Check it thoroughly at home, find the root cause, find the basic root cause, and then spray it with radar or other spray for a while when people are not at home.

(1) Stomach poison: A drug that enters insects through the digestive system of pests and causes them to be poisoned and die. It is mainly used to control pests that bite, chew and eat by chewing mouthparts.

(2) The contact agent is the same as the agent that contacts the epidermis of pests or penetrates into insects to make them poisoned and die, such as deltamethrin.

(3) systemic agents are absorbed into plants through their leaves, stems and roots, transported, diffused and retained in plants, or produce metabolites. When pests feed on plant tissues or juices, they will be poisoned and die. It is mainly used for preventing and controlling piercing-sucking mouthparts pests.

Extended data:

The pesticide can be released from nano silicon-based oxide for a long time by using the large adsorption capacity and slow release function of nano silicon-based oxide. Overcomes the shortcomings of short pesticide residue period, instability to light and easy decomposition and failure in the prior art. ..

Insecticides kill insects in order to prevent the transmission function of efferent neurons or the decomposition of neurotransmitters in prominent gaps, so the effector (that is, the distal end of efferent neurons and their muscles) is always excited and then spasms to death.
