Mosquitoes like sunny, dark, humid and watery places, so most of them like to go out at night, but different kinds of mosquitoes have different habits. Some mosquitoes like to live indoors, mostly under mosquito nets, under beds, in corners and behind doors. There are more than 2,000 species of mosquitoes in the world, and more than 300 species have been found in China. Culex pipiens, Anopheles mosquitoes and Aedes mosquitoes are the three main blood-sucking mosquitoes, and they are also the most common mosquitoes. These three kinds of mosquitoes generally do not fly high, and the number of mosquitoes above the sixth floor will be significantly reduced. If there are mosquitoes at the top, most of them are Culex pipiens, also known as house mosquitoes, which mainly bite people and animals after dusk and are easy to spread Japanese encephalitis. However, Culex pipiens is also the dumbest of the three mosquitoes. It likes to haunt after turning off the lights and pick on its skin before biting, so sensitive people will feel it when it stops. If it is fan-killed, it will have no chance to "attack". Anopheles mosquitoes have black and gray spots on their wings. When stopping, the head is close to the ground, and the abdomen is lifted upward, and the body forms an oblique angle of 30-45 degrees with the surface of the object, while Culex pipiens and Aedes pipiens stand parallel to the surface of the object when stopping, which is easy to distinguish. Anopheles mainly attacks humans at dawn and mainly spreads malaria and filariasis. Anopheles mosquitoes are not as cunning as Aedes mosquitoes. When people felt it, it didn't suck blood but bit it. At this time, even if you are killed, Pi will still pack. Aedes mosquitoes are often called "flower-footed mosquitoes" and can spread Japanese encephalitis and dengue fever. The dengue fever epidemic discovered in Cixi, Zhejiang Province last year was due to the spread of Aedes mosquitoes. When Aedes bites, people usually don't feel it. By the time they felt itchy, it had already "eaten and drunk" and flew away. Aedes mosquitoes are mostly active during the day. There are three major factors that affect the taste of the world and the fear of being bitten by mosquitoes. First, the carbon dioxide exhaled by the respiratory tract is the directional odor source of mosquitoes, which can help mosquitoes find people and then bite. The second is the heat. Fat people are more likely to be bitten by mosquitoes, and dark clothes absorb heat to attract mosquitoes. The third is excrement. Mosquitoes love to bite people with big pores and sweat a lot. Generally speaking, men are more likely to attract mosquitoes than women, young people are more likely to attract mosquitoes than the elderly, and healthy people are more likely to attract mosquitoes than patients. Children have a strong metabolism and are easily favored by mosquitoes. In addition, when women come to menstruation, their secretions will change, which makes them more likely to attract mosquitoes. Mosquitoes are also attracted after sweating, so it is best to take a bath quickly after exercise. If you sweat less, mosquitoes will bite less. Several methods to deal with mosquitoes cut off the breeding water source. The eggs, larvae and pupae of mosquitoes all live in water. Mosquitoes can't breed as long as their breeding water source is cut off. According to different temperatures, the incubation period of mosquito eggs is 7- 14 days. Therefore, it is necessary to deal with the accumulated water and put away the pots and pans placed in the open air. If there are aquatic plants at home and in the office, remember to change the water every two days, otherwise mosquitoes will easily breed. It is also a good idea to raise fish in the water, because mosquito larvae happen to be the favorite food of small fish. Floor drains, sewers and other places to prevent water accumulation, and often spray some pesticides to prevent mosquitoes from entering the living environment. Screen window screen door mosquito net. Families with pregnant women or young children can choose to avoid the impact of mosquito-repellent incense and pesticides on the human body. Mosquito-repellent incense and pesticides should be changed frequently. Mosquitoes, like germs, can develop drug resistance. The Municipal Center for Disease Control and Prevention has monitored the mosquito population resistant to some pesticides. A pesticide or mosquito-repellent incense is likely to be resistant to mosquitoes in a certain area after long-term use, so it is used in a different brand every once in a while. When traveling in summer, wear long-sleeved shirts and trousers for protection. Apply mosquito repellent to bare skin every 4 hours or so. Wear light clothes. Aedes likes to park on black clothes. Use less soap in the shower. Mosquitoes like nectar, and the probability of being bitten by mosquitoes will increase after using perfume, cosmetics, cream and other floral items, except sandalwood. Eat more vegetables. Some vegetables contain smells that mosquitoes don't like, such as vegetables containing carotene, garlic and other spicy vegetables. After people eat it, mosquitoes will stay away from you.
