The pests

1. Rodents: rats are reservoirs of many diseases; Bubonic plague is one of the most harmful mouse-borne diseases. The harm of rats is also reflected in stealing food seeds, nibbling seedlings, spoiling wires and cables, destroying buildings and furniture, clothing, books and so on; Therefore, since ancient times, mice have been hated and beaten by everyone. There are many kinds of mice, more than 150 of which have been found in China, among which there are more than 10 species, such as rattusnormouse, yellow chest rat, small house rat, big hamster, eastern vole, yellow hairy rat, long-clawed gerbil and dauer's yellow rat. Rats should be killed according to their living habits by physical killing (such as rat traps, rat cages, buckles, sticky mice, digging holes, etc.) and drug poisoning, among which drug poisoning is the most effective and commonly used method



Cockroach: the scientific name of cockroach is cockroach. Most cockroaches are wild and a few live indoors. They not only steal food and pollute things, but also spread some intestinal diseases. Cockroach species around the world very much, has more than 3500 kinds, there are about 170 species have been found in our country, the life of cockroaches was like darkness is afraid of light, quick, hide in the dark hidden during the day, night is moving around, it's hunger resistance is strong, particularly like food containing sugar and starch for, main perched place is warm, moist, rich food, sometimes in bookcase, shoes box, inside the wardrobe is also common. In addition to the physical methods of sticky trapping, trapping, scalding and killing, etc., the poison baits with attractive effect are more advanced in the use of chemical drugs. Poison is very effective



3. Flies: flies harass people and livestock, worsen the environment, spread a variety of diseases, and some flies can also sting and suck people and livestock, causing diseases and great harm. More than 500 species of flies are known to have developed in four stages: egg, larva, pupa, and adult. When the temperature is right, the reproduction is rapid, which can complete 7-8 generations per year, and 10-12 generations per year in warm areas in the south. Flies like things with foul smell and odour, so doing a good job in environmental sanitation and eliminating the breeding conditions of flies, as well as cooperating with the application of chemical drugs and physical instruments, is undoubtedly the key to the effectiveness of fly control.



4. Mosquitoes: there are a wide variety of mosquitoes. There are more than 3,000 species known around the world, and there are more than 300 species in China. The characteristic of mosquito is variety much, amount is big, distributing wide, breed fast, at the same time the growth of mosquito and outside air temperature and environmental factor are having close concern. Therefore, both control of biogenic conditions and drug should be adopted for mosquito killing.



5. Termites: they are also called arthropoda, insecta, and isoptera, similar to the social life of ant camps. Their social classes are queen ant, queen ant, soldier ant, and worker ant. Although termites and ants are generally called ants together (see formicoidea), in terms of the classification status of termite social system, termites belong to the lower level of semi-metamorphosis insects, while ants belong to the higher level of total metamorphosis insects. According to the fossil, termites probably developed from the ancient orthoptera insects and first appeared in the Permian period 200 million years ago. One might mistake a termite for an ant, but termites and ants are two different species. Termites are soft and small, usually long and round, white, pale yellow, russet to dark brown. Head front mouth type or bottom mouth type, can move freely. Antennae moniliform, abdominal base stout, wings equal length before and after; The antennae are geniculate, the abdomen is thin and thin, and the anterior wing is larger than the posterior wing. Chinese ancient books call ants, ants, ants, ants flying, ants trying, ants, slaves, etc., all mixed with ants. Song dynasty began to have the name of termites, and determine the nickname for termites. Termites are found in tropical and subtropical regions and feed on wood or cellulose. Termites are polymorphous, gregarious insects with strict division of labor. Once the group organization is destroyed, it is difficult to survive. More than 2,000 are known worldwide. In China, there are more than 300 species in all the other 4 families, except for the family aestidae, which has not been found yet. It's very widespread. In view of all kinds of termites in our country, we can take both drug elimination and physical control measures, and often review the root cause. Control the living environment of termites can gradually eliminate the harm of termites.
