Because pregnant women and children are easy to “attract” mosquitoes, the old city nine months pregnant Ms. Zhang and Jianxi District daughter more than two years old Ms. Li are a little nervous. To deal with mosquitoes, they collected a lot of online crazy mosquito tricks, but I do not know whether these tricks work or not. 1, whether to attract mosquitoes, and blood type has nothing to do with To prevent mosquitoes, we must first understand the “temperament” of mosquitoes. Mosquitoes are one of the four pests, male mosquitoes to plant nectar and sap for food, female mosquitoes after mating blood to promote the development of their ovaries. The mosquito’s life is divided into four periods of eggs, larvae, pupae, adults, to complete a cycle generally takes about 15 days. Among them, eggs, larvae and pupae need to be completed in still water. Like other insects, mosquitoes also have a pair of tentacles on the top of the head, they rely on the pair of tentacles to sense the smell, temperature, humidity and other information, so as to find the blood-sucking target. A person is not mosquitoes, and its blood type has no relationship due to mosquitoes with weak phototropism, fear of light, and do not like the light too dark, most like to suck blood in a low light environment, so it loves to bite people wearing dark clothes and darker skin; mosquitoes like high temperature, high humidity, so high body temperature of pregnant women, infants and young people who love to sweat, fat people, etc., are easy to become the target of mosquito attacks; body emitting odor (not Including mosquitoes hate mint flavor, etc.) heavy people more favored by mosquitoes, such as a lot of exercise, metabolism and the use of cosmetics people. 2, online rumors mosquito tricks, are not old reliable in the home to place alkaline water basin online rumors: in the corner of the home for a long time to place a water basin, in the water basin poured into the washing powder and soapy water, make a simple alkaline water basin. As the fragrance of washing powder and soap will induce mosquitoes to lay eggs, and the eggs of mosquitoes can not survive in an alkaline environment, therefore, the number of mosquitoes will be less and less. Mosquitoes need to lay eggs, hatching process are completed in the still water, placed in the home for a long time alkaline water basin not only can not effectively remove mosquitoes, but will attract more mosquitoes. This method in the mosquito breeding places may be a bit useful, but in the residents of the home is not very useful.
