What is the relationship between "four pests" and vectors?

Rats, cockroaches, mosquitoes and flies in the "four pests" can carry a large number of pathogenic bacteria and viruses, which are several representative types of vectors. They have attracted more attention only because of their large number and strong reproduction, which is closely related to human life. In fact, vectors include mites, ticks, lice, fleas and bedbugs.

Vector refers to the organisms that directly or indirectly spread diseases and endanger and threaten human health, mainly including rats, flies, mosquitoes, cockroaches and other animals. Zhu Hongjuan, director of the Municipal Health Planning Commission, pointed out that vector control is the core index of creating a national health city, and it is also the focus and difficulty of health creation, which is directly related to the success or failure of health creation.

At present, there are 39 notifiable infectious diseases in China, which are divided into three categories: A, B and C, among which rats are closely related to plague, leptospirosis and epidemic hemorrhagic fever, and mosquitoes are closely related to epidemic encephalitis B, malaria, dengue fever and filariasis. In addition, flies and cockroaches also carry a variety of bacteria and viruses, which can spread a variety of diseases and endanger human health.

Extended data:

This is the most economical and effective way to clear the breeding ground of garbage and four pests. According to the habit of "four evils", the formula of "pour, block, clean and lure" is given.

1, stagnant water breeds mosquitoes, and the focus of mosquito control is "below"

Every April to 10 is the breeding season for mosquitoes, who like to lay eggs in stagnant water. The sundries piled up in the public area of the residential area will form all kinds of accumulated water after the rain, which needs to be removed in time. The accumulated water in pools, flower beds, drainage ditches and underground garages in the community is easily overlooked. Residents grow flowers on the balcony, and the bottles and jars that receive rainwater are breeding grounds for mosquitoes around them. The accumulated water should be emptied in time, and the container should be inverted.

2. The key to killing rats is "blocking" when rats drill holes.

Most of the rats in Wuhan are Rattus norvegicus and Rattus flavipectus, and the adult rats of the two kinds of rats have higher IQ. First of all, prevent "input" when killing rats at home, and find a gap between the pipes at home and the holes connected with the outside world to prevent rats from entering. Collect food at home in time, don't be exposed to the sun, put kitchen waste into the trash can in time, and don't stay at the door for the night. Rodents in residential areas can be killed by professional pest control teams by putting rodenticide, rat glue and other professional methods to ensure the safety of residents.

3, flies like dirty, and the focus of killing flies is "net"

Flies like rotten food, and garbage dump is their food source and breeding ground. Flies have a strong reproductive ability, so it is necessary to grasp the stage of maggot pupa and not fly. Removing domestic garbage, animal carcasses and closed septic tanks is the key to killing flies. Residential areas and food markets should prevent garbage from being exposed, and trash cans should be covered at any time to prevent the odor emitted by garbage from attracting flies. Residents can install screen doors and screens to keep flies out, and fly killing lights can be placed in canteens and hotels.

4. Cockroaches love sweet and sour, and the key to killing cockroaches is "temptation"

Cockroaches like warm and humid, and they like sweet and sour food. Cake, bread and fruit are all its delicacies. To kill cockroaches at home, we must first keep the environment clean, and don't leave food residue on the desktop, ground and corner. Blattella germanica, a kind of cockroach, has strong reproductive ability and is called "the most widely distributed and difficult to control household hygiene pest in the world". Because of its small size, it is easy to hide in a very small gap, and cockroach pesticides are often inaccessible. Residents should try their best to fill these gaps.

Toothpaste-shaped glue bait can be used as the first choice to kill cockroaches, based on the principle of "small quantity and wide area" Each medicine point is only the size of mung bean, generally a little medicine every 20-50 cm, and the medicine is placed in the corner and gap. This kind of glue bait is safe to human body as long as it is produced by regular manufacturers.
