It's hot and there are cockroaches in the house. What can be done to prevent them?

Seven ways to kill cockroaches: 1. Fresh cucumbers repel cockroaches. Put fresh cucumbers in the cupboard, and cockroaches won't come near the cupboard. After two or three days of fresh cucumber, cut it, continue to smell the cucumber, and continue to drive away cockroaches effectively. 2. Fresh peach leaves repel cockroaches. Put the freshly picked peach leaves in a place frequented by cockroaches, and the cockroaches will avoid when they smell the peach leaves. Onions can drive away cockroaches. If you put a plate of chopped onions indoors, cockroaches will run away immediately when they smell it, and at the same time, they can delay the deterioration of other food indoors. (4) Cockroaches mainly live in the kitchen, and all the gaps between the cabinet frame and the wall, the gaps between the walls and the drainage pipes in the kitchen are their shelters. You can spray pesticides to plug the gap and scald it with boiling water. (5) If there are too many cockroaches in the decorated room, it is best to close the doors and windows, and use alcohol lamps to light 10% Didi Wei. Burning for an hour or two can kill a lot of cockroaches. But remember, cockroaches are extremely vital, and sometimes they are just in a coma, not really dead. So you can't throw it away as garbage. You'd better scald it with boiling water. Otherwise, many cockroaches will wake up in ten minutes, which is equivalent to "releasing tigers to the mountains". (6) Put the sticky paper in the place where cockroaches often haunt. This method has little effect, which is equivalent to "waiting for the rabbit".

(7) Don't be beaten by flies or trampled to death with your feet. It is best to stick one on the other with cockroach paper, which is very accurate and effective. Stepping on your feet will spread a lot of germs and viruses on cockroaches everywhere.
