How do flies survive the winter?
Flies are very annoying creatures that can carry all kinds of germs and seem to be inexhaustible, so how do flies survive the winter? Let's take a look at it together.
First, how do flies survive the winter?
1. There are many kinds of flies. Take our common houseflies as an example. In winter, they usually lay their eggs in the feces of people or animals. Compared with the cold outdoor, the temperature in the feces is higher, which can ensure that the eggs will not freeze to death. By the time of spring and summer, these flies will begin to breed again.
2. Another way for flies to spend the winter is very simple, such as flying into hotter rooms, or some caves to avoid the cold. When we clean the house in winter, we occasionally find some big flies that can't fly, most of which belong to this category.
Second, how to control flies?
Physical prevention and control: the physical prevention and control in livestock and poultry farms is to clean up feces in time, and special attention should be paid to the faeces and sewage in the dead corners. As far as possible, the waste bedding and sick and dead livestock and poultry in livestock and poultry farms should also be properly dealt with in a timely manner. The drinking water and feeding system of poultry farms should be checked regularly to ensure small water leakage and small sprinkling; when picking up eggs, try to avoid egg damage. Properly adjust the ventilation system of the chicken house to ensure a suitable wind speed and prevent excessive ammonia content.
2. Biological control: biological control of flies is to cultivate natural enemies of flies in faeces. Natural enemies of flies, including beetles, cochlea and wasps, are predicted in natural conditions. Fly natural enemies in feces rarely dry livestock and poultry manure is conducive to the growth of fly natural enemies.
3. Chemical control: chemical drugs are the most effective way to control flies. Chemical drugs can only kill Chengying, but also can kill fly eggs and larvae.
