How to kill hateful cockroaches?

Someone asked the same question the other day. My answer was accepted and graded. The content is as follows. I hope it helps you.

I bought cockroach medicine made in Harbin and used it continuously for 30 days. It feels good. At the same time, when cockroaches' nests are found, it is very enjoyable to destroy them with boiling water or windproof lighters. The cockroach in my family was first extinct four years ago. This year, they were smoked to my house because of the decoration and paint smell downstairs. I can't help it, but it's still cockroach medicine, which is a bit like a cold granule and is placed in the kitchen, stove and vegetable storage box. Four or five people die every day. When you see something alive, wash it with boiling water on the spot, even if it runs into the crack in the wall, it is poured with boiling water. When you meet a gap in a metal structure, burn it with a windproof lighter. I don't have to deal with it after the burning and fragrant smell comes out. It is most effective in the middle of the night. Now, there is no one.
