Why mosquitoes bite so hard in autumn

Mosquitoes generally start in May and reach their peak in mid to late August. When the temperature drops below 10 degrees Celsius, the remaining mosquitoes will stop breeding and enter hibernation without food. Many people think that mosquitoes only come in the summer and that they will die out in the fall.

In fact, early autumn and mid-autumn are both active periods for mosquitoes. When the weather is too hot, the vitality of mosquitoes will be weakened. The best temperature for mosquitoes to survive is between 28 and 30 degrees Celsius, and mosquitoes are more active on rainy days.

Female mosquitoes bite indoors, and they suck blood to provide more nutrients to their offspring when they lay eggs. Autumn is rainy and the temperatures are pleasant, creating more opportunities for mosquitoes to breed. Therefore, the autumn mosquito bites people more fiercely, sucks more blood, and the mosquito carries more germs, so there is a saying that the autumn mosquito is more poisonous than the summer mosquito.

However, the lifespan of mosquitoes is generally 1 to 4 weeks, and as the weather gradually cools, mosquitoes will gradually disappear in the half month after the Mid-Autumn Festival.

According to the World Health Organization, in sub-Saharan Africa alone, nearly 1 million people die each year from mosquito-borne falciparum malaria. We should do a better job of mosquito prevention for young children in autumn.

Because if you don't bite again, it's winter, and how can you suck blood when you freeze to death when it's cold? So let's bite if you can.

Autumn is the last time the female mosquito sucks blood and lays eggs, so it is more aggressive.

After the beginning of autumn, mosquitoes begin to reproduce, so the density of mosquitoes is larger, and the chance of being bitten by mosquitoes may be greater.

Its saliva or venom invades**, because the saliva of mosquitoes or the leaching fluid of venom glands contains a variety of antigenic components, which can cause inflammation by allergic reaction with antibodies after entering the human body**.
