Why are mosquitoes in autumn worse than those in summer?

Autumn is the breeding season of mosquitoes, so mosquitoes in autumn are particularly poisonous and often leave redness on the skin after biting. In order to get better nutrition for future generations, mosquitoes are fiercer than usual in the breeding season and have super fighting capacity.

Mosquitoes begin to appear from April to May every year, reaching a peak in the middle and late August. When the temperature drops below 10 degrees Celsius, mosquitoes will stop breeding and die in large numbers. Few mosquitoes live in warm and secluded places, such as cracks in the wall that can keep out the wind and cold. So mosquitoes will not disappear until 10- 1 1. Mosquitoes can be found all year round in places with high temperature all year round.

Precautions and key points for mosquito control:

Female mosquitoes suck blood, and female mosquitoes must suck blood from ovaries to develop and reproduce. Female mosquitoes begin to suck blood 2 ~ 3 days after emergence, and many factors such as temperature, humidity and light will affect mosquito's blood-sucking activity. When the temperature is above 10℃, begin to suck blood; Generally, Aedes mosquitoes mostly suck blood during the day, while Anopheles mosquitoes and Culex pipiens mostly suck blood at night. But there is no strict selectivity, so mosquitoes can spread human and animal diseases.

Mosquitoes need to find a place to live after eclosion and blood feeding. Generally speaking, mosquitoes like to live in hidden, dark and poorly ventilated places, such as under the bed, behind cabinets, behind doors, crevices in walls, barns and basements, as well as outdoor lawns, caves, cellars, bridge opening and crevices.
