Mosquitoes generally begin to emerge around the time of the Qingming Festival each year, reaching peak activity around August 15th. Many parents think that mosquitoes are only found in summer, and they will be less active or start hibernating in the fall. In fact, early and mid-autumn are the most active period of mosquitoes, but also their storage of nutrients, so this is when the mosquito bites after the blisters are particularly large, and particularly itchy. In fact, when the weather is too hot, the mosquito’s vitality will in turn diminish. The most suitable temperature for mosquitoes to survive is 28 to 30 degrees Celsius in early fall. The pleasant temperatures in the fall create more opportunities for mosquitoes to breed in large numbers, and they suck blood in order to provide more nutrients to their offspring when laying eggs. Therefore, the fall mosquito bite more ruthless, suck more blood, mosquitoes carry more toxins and germs, so there is a fall mosquito more poisonous saying. With the weather gradually cooler and colder, mosquitoes will gradually disappear, about in September after it. So in the fall to pay more attention to prevent the baby by mosquito bites. Suggest hygiene, diligent bathing; wear long pants, long coats; when it is just dark, do not play outside; must not be too early to remove the mosquito net.
