CATDOLL : CATDOLL: What is the main reason for cockroaches in the house? What harm will cockroaches cause to people?

Generally, cockroaches don't breed in houses. They are brought in from other places, such as hotels where cockroaches live, parcels sent by mail, and the spread of cockroach populations (for example, if you have cockroaches in your house, your neighbor's house may have them two days later, and the whole neighborhood may be occupied by cockroaches a week later). Cockroaches are alien species. The origin of indoor cockroaches originated in Africa, and then gradually spread to various continents. All the indoor cockroaches in China are imported from abroad and gradually spread through the transportation of various goods.

The harm of cockroaches to humans is second only to houseflies. Cockroaches carry bacteria all over their bodies. Food contaminated by cockroaches can cause severe gastroenteritis, food poisoning or dysentery. It is a carrier of infectious bacteria and viruses. Because it feeds and crawls everywhere, it has a wide range of invasions and a variety of diets. It can move around in garbage, toilets, washrooms, and feed on food. If you eat food contaminated by cockroaches, you may be infected with diseases. Therefore, the harm of cockroaches spreading diseases cannot be ignored. Cockroaches have been proven to carry about 40-50 bacteria that are pathogenic to vertebrates, such as Shigella dysenteriae, Escherichia coli, and Yersinia pestis. They can cause food poisoning and spread pathogenic bacteria such as hepatitis, poliomyelitis, pneumonia, and tuberculosis. It is also an intermediate host of many parasites. It can carry eggs of many worms such as roundworms, duodenal hookworms, beef tapeworms, burn worms, whipworms, etc. It also carries many protozoa, four of which are pathogenic to humans or animals, such as dysentery amoeba. Because cockroaches produce smelly secretions when feeding, which spoil the taste of food, people with weak or sensitive constitutions will have various allergic reactions if they come into contact with cockroach-contaminated food or cockroach feces and secretions and polluted air. In addition to spreading diseases, cockroaches bring us greater annoyance and seriously interfere with our lives. In the home, cockroaches like to hide in the gaps and dark corners of the kitchen, food cabinets, feed storage, toilets, etc. Not only does it pollute the home environment, but it also changes the quality of food and oil.

The quality of food and even food that is inedible is affected; clothes and daily necessities are not spared.
