Rats: The harm of rats is well known, it not only steals food, bites furniture, clothing, books and stationery, destroys buildings, bites off wires, etc., causing economic losses, and is the most serious in the "four pests", rats mainly spread plague, leptospirosis, lambiasis, epidemic hemorrhagic fever, endemic rash, typhoid fever and other infectious diseases through their ectoparasites (rat lice) bites and blood sucking or their excrement pollution.

The first is flies, and there are not only many types of flies, but also a wide distribution, contact with other animals is more frequent, and its flight ability is also very strong, because there are more things in contact, so it is easier to contaminate food.
2. The main hazard of mosquitoes is to spread diseases. There are more than 80 mosquito-borne diseases. In fact, male mosquitoes feed on plant sap, while female mosquitoes feed on human or animal blood.
However, mosquitoes have their own anti-virus organs and cannot be infected by bites, while blood-sucking female mosquitoes are intermediate transmitters of a variety of pathogens, which poses a direct threat to human health.

However, rats are the most common among people, and in fact, they can not only transmit a variety of pathogens, but also steal and spoil food, gnaw on crops, and even destroy saplings, resulting in the entire growth of forests. In addition, rats often gnaw on furniture, clothing, books and documents, etc., which directly causes great trouble to people's lives.
4. Cockroaches can be artificially infected and cause bacteria. Cockroaches can carry a variety of worm eggs such as roundworms, duodenal hook nematodes, beef tapeworms, windworms, whipworms, etc. Cockroaches prefer to stay in warm, humid, abundant food, and narrow spaces for life, such as kitchens, canteens, food warehouses, utility rooms and other places are the most common.
