Cockroaches are also called cockroaches and oil thieves. According to experts' research, it has existed in the world for more than 300 million years, earlier than human beings. It is not only annoying in appearance, but also stinks, and it is a pest that everyone hates. Although it has wings, its flying ability is very poor, mainly by crawling. It eats a wide range of food, not only human excrement such as stool and phlegm, but also human food, especially starch and sugar food. When feeding, it is like a mosquito sucking blood. First, spit out the secretions in the stomach, and then suck the food. Cockroaches carry a variety of germs, viruses and parasitic eggs in their mouths, especially in their intestines, and spread diseases by polluting food and utensils. According to scientists' laboratory tests, cockroaches contain more than 40 kinds of pathogenic bacteria such as Salmonella, Shigella, Staphylococcus, Tuberculosis, Pseudomonas aeruginosa and Aspergillus flavus. There are seven kinds of parasitic eggs, such as roundworm, hookworm and hepatitis virus. These bacteria and viruses can survive in cockroaches for 12 days and are constantly excreted from feces. Therefore, it is easy to spread dysentery, typhoid fever and hepatitis, causing diarrhea and purulent infection.
Cockroaches are nocturnal insects, and they are very fertile. If the climate is mild and moderate, they can breed a nest of 40 to 50 in ten days. In spring, everything recovers and the climate gets warmer, which is the most prosperous season for cockroaches to breed. Killing a cockroach at this time is equivalent to killing hundreds of thousands in summer and autumn. So how do you kill cockroaches?
(1) Cockroaches mainly live in the kitchen. They live in all the gaps between the cabinet frame and the wall, in the cracks in the wall, and in the drainage pipes of the kitchen. You can spray pesticides to plug the gap and scald it with boiling water.
(2) If there are too many cockroaches in the decorated room, it's 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".
(3) Put the sticky paper in the place where cockroaches often haunt. This method has little effect, which is equivalent to "waiting for the rabbit".
(4) Cockroaches should not be beaten by flies or trampled to death by their 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.

Note: After killing cockroaches, clean up dead cockroaches immediately after spraying suspending agent. Never step on them with your feet or pat or hit them with anything.

They are not dead, and they will soon run out, so they must be burned to kill them completely. I wonder if you have this suspending agent and bait.
