1 Soapy water: As we all know, cockroaches can't be killed. After you deal with a batch, there will still be many, hiding in corners you don't know, and multiplying in their way, so it's best to kill them all. You can pour some soapy water into the places where cockroaches often haunt. If cockroaches pass by, their bellies will get soapy water, so cockroaches will soon stop moving.

2 potatoes and boric acid: cockroaches like to circle around the food when they are in the kitchen, and they will climb on the food when they are looking for food. But all the food crawled by cockroaches is viral and must be thrown away. Then you can also kill it with food, prepare a potato, peel it, steam it, mash it after steaming, then add a proper amount of boric acid and mix it evenly, and then knead it into a small lump. It is possible for cockroaches to put it in.

3 Sprinkle washing powder: Cockroaches will also appear in the kitchen, because there are more food in the kitchen, and sometimes it is messy. Cockroaches like to stay in these places, and if you want to step on them with your feet, it is usually difficult for you to step on them. Even if you step on them, it is mainly the eggs in the cockroach's stomach. You can sprinkle washing powder on the places where cockroaches often appear. If you eat washing powder, cockroaches will easily die. Just scald them with boiling water.

4 Put orange peel or lemon peel: Cockroaches like to appear in closets or closed places, because it is convenient for them to lay eggs and breed. Sometimes when you open the closets, there will be a lot of cockroach droppings, and you will dislike your clothes. We can cut the remaining orange peel or lemon peel into small pieces and bake them, and then put them in closets. Cockroaches will not come over when they smell this smell.

5 banana peels and detergent water: cockroaches are always elusive. Sometimes you just see them coming out. When you just want to pat them with your shoes, they quickly disappear. If you look for them again, you will never find them. Our leftover banana peels are also useful to them. Cut them into blocks, then put them in detergent mixed water, and then dip them in detergent water.
