Where are the flies and mosquitoes in winter?

Some people may find it strange that flies and mosquitoes swarm in summer, but when the weather gets cold in autumn, flies and mosquitoes magically decrease or even disappear. The reason for this is actually very simple, that is, mosquitoes and flies can not adapt to the cold climate. When the temperature is below 10 degrees, most flies and mosquitoes freeze to death, and only a few flies and mosquitoes with good health barely survive in places such as cracks in the wall.

Flies and mosquitoes can't stand the low temperature. Although flies and mosquitoes have a longer survival history than humans, they are not as good as humans in adapting to the environmental temperature. When the temperature is too high or too low, they will directly lead to the death of flies and mosquitoes. When the temperature is lower than 10 degrees in autumn and winter, mosquitoes will not only stop breeding activities, but also die in large numbers, and only a few mosquitoes with good health can barely survive. Flies move between 20 and 35 degrees and can eat and lay eggs normally. However, when the temperature rises above 35 degrees, flies will stop moving, and when the temperature rises above 45 degrees, they will die quickly. When the temperature is only a few degrees, flies can only crawl on the ground. If the temperature is lower, flies will freeze to death.

Flies There are many kinds of flies, and the ways of wintering are also different. Some flies, including the common housefly, have a short life span and lay eggs in feces before they die. When the next spring and summer comes and the temperature and humidity are suitable, small flies will hatch from it. There is also a big whitefly, which has strong resistance and is not so easy to freeze to death. When the temperature drops, they will find cracks or small holes in the walls of the room to hide. If it is not particularly cold in winter, they can spend the winter safely.

Mosquitoes are rampant in August and September, but when the temperature drops in autumn and winter, mosquitoes will die on their own because they can't adapt to the cold climate. However, a few mosquitoes with strong vitality can survive. They will look for cracks on walls, near heating pipes, behind wardrobes and cabinets to avoid the winter wind. Like other hibernating animals, many mosquitoes can last until the next spring when the weather gets warmer.
