[0002] Pests such as rats, mosquitoes, cockroaches, bedbugs, etc. carry many kinds of bacteria, like to steal food, etc., and are easy to spread diseases. They also destroy furniture, houses, and clothes, and people and animals will feel uncomfortable after being bitten by them. At the same time, many people are afraid of these pests, and they will feel nauseous and vomit when they see them, especially women and children. Therefore, people always think of various ways to drive away and kill these pests.

[0003] In traditional technology, people use drugs, clamps, chemicals and other methods. These methods may be effective at the beginning, but after a long time, the pests will become familiar with them and will not be fooled again. The insect repellent effect is not good.
