Talking about killing cockroaches

Washing powder is a safe and efficient cockroach killer. The method is to directly sprinkle the washing powder on the places frequented by cockroaches, and the cockroaches will die after eating the washing powder.

Making balls the size of rice grains with borax and sweetened flour, and putting them in places where cockroaches are infested, can also effectively kill cockroaches.

Commonly used soda and sugar are mixed in haunted places. After about 3- 10 days, cockroaches will disappear automatically, so don't try.

When boric acid is used to mop the floor, cockroaches and ants will be afraid to approach when they smell boric acid, thus achieving the effect of preventing cockroaches.

Orange peel and lemon peel can also prevent cockroaches if they are put in the cupboard after drying.

Grasping bottles, such as beer bottles and glass bottles, can be used as long as the bottle mouth is small, the inside is smooth and the bottle is high enough. Add some sugar water to it, and cockroaches will climb in when they smell the fragrance. They can't climb out any more by using the high-slippery characteristics of bottles.

Tung oil becomes a sticky colloid after heating, which is coated on cardboard and put on delicious food. Cockroaches get stuck when they find something to eat.

You can also put some cucumber or onion slices in the cupboard to prevent cockroaches.
