Cockroaches have spread from a few big cities to almost small and medium-sized cities, even small market towns and rural areas since they entered China for 20 years. According to the data of the National Center for Disease Control and Prevention, a female cockroach can breed up to one million offspring a year. With the extensive use of pesticides, cockroaches have developed strong drug resistance, and most pesticides are ineffective. Cockroaches have replaced mice as the first of the four pests!

If there are cockroaches in your living environment, you can recall whether there are any inexplicable allergic reactions, asthma, dermatitis, gastroenteritis, food poisoning or dysentery. The secretions, excreta, vomit, bacteria, parasite eggs, dry powder, etc. of cockroaches can cause allergic reactions after human contact.

Cockroaches eat, crawl, excrete, walk all the way and spread bacteria everywhere. Crawling around in your bed, crawling around in your closet, even crawling around in the wan where you eat. Is it disgusting? . . ) The living environment is polluted by cockroaches, and people come into contact with these bacteria, which causes various diseases.

In fact, many people have cockroaches at home. They use all kinds of methods and buy all kinds of tools, but they can't get rid of them. In the same city, some people never have cockroaches at home. Why?

Cockroaches live in groups;

It is often found that in a habitat, there are always as few as a few, and as many as dozens or hundreds of them gather together, mainly because of the lure of pheromones. Both adults and nymphs of cockroaches can secrete an aggregation pheromone, which is secreted by rectal pad and can be excreted with feces. In the place where cockroaches live, brown spots on their feces can often be seen. The more feces, the more cockroaches gather.

We live in a large area, and no matter how much medicine we spray at home, cockroaches will still come back, because you are not the only one who keeps cockroaches, but the whole building and even the whole community!

We humans have a sense of territory, knowing that we can enter our own house, but others can't just enter it. However, cockroaches don't have this consciousness. Cockroaches enter your home from other people's homes, just like entering your kitchen from your toilet. For cockroaches, it makes no difference! If you have seen cockroaches in your toilet, they must be in your kitchen or bedroom.

Therefore, to eradicate cockroaches completely, it is not enough to kill cockroaches in your own home, let alone go to your neighbor's house to kill cockroaches. What you can do is to clean up your home thoroughly, take full precautions to prevent another invasion, and build an invincible castle so that pests can get in seamlessly.
