Vector refers to organisms that directly or indirectly transmit diseases (human diseases) and endanger and threaten human health. Hazard of vector: It can directly affect or endanger the normal life of human beings through biting and polluting food. Spread a series of important infectious diseases through various channels.
Vector control measures:
1, breeding ground management is the fundamental measure of vector control. Thoroughly eradicate the breeding ground of vectors from the source, eliminate the breeding and living environment of vectors, reduce the density of vectors, and reduce the harm of vectors. Mosquitoes come from water; Flies come from filth; The mouse came out of the hole; Cockroaches come from cracks.
2. Mosquitoes can't reproduce without boiling water, so cleaning up indoor and outdoor stagnant ponds in time can effectively control mosquito density. The reproduction of flies is inseparable from dirty places such as garbage and feces, and environmental sanitation is the key. The survival and reproduction of rats are mostly in caves. Plugging all kinds of loopholes, not pouring kitchen waste into the sewer, and managing garbage and feces can reduce their reproduction and harm.
Cockroaches parasitize in some small gaps, and places where cockroaches are easy to breed, such as kitchens, warehouses and power distribution rooms, should be stitched in time to prevent breeding.
3, increase the necessary protective equipment to prevent the vector from contacting with human beings, so as to reduce the harm. Install door curtain, screen window, floor drain and rat net, and block all kinds of holes communicating with the outside with cement or putty to prevent vectors from entering the room and reduce contact with people.
4. Take timely killing measures to reduce the density of vectors. Physical killing is the main method, supplemented by chemical disinfection. The focus of chemical disinfection is to adopt new technologies and methods, use environmentally friendly, efficient and low-toxic sanitary pesticides to control disease vectors, and reduce the adverse effects of various measures, especially chemical control measures, on the natural environment and human health.
