How Do Flies Survive the Winter? A Detailed Explanation of Fly Overwintering Methods

Flies are extremely annoying creatures that carry all kinds of pathogens and seem impossible to wipe out completely, so how do flies survive the winter? Let's take a look together below.

1. How do flies survive the winter?

1. There are many species of flies. Taking the common housefly as an example, in winter they generally lay their eggs in human or animal feces. Compared with the cold outdoors, the temperature inside feces is higher, which can ensure the eggs do not freeze to death. When spring and summer arrive, these flies begin to reproduce anew.

2. Another way flies overwinter is very simple: for example, they fly into warmer indoor spaces or into caves to escape the cold. The cluster fly adopts this method. When we clean the house in winter, we occasionally find some larger flies that cannot fly, most of which belong to this category.

2. How to control flies?

1. Physical control: Physical control in livestock and poultry farms means promptly cleaning up feces, with special attention to feces and sewage in dead corners, keeping livestock and poultry feces as dry as possible. Old bedding material and dead livestock and poultry on the farm should also be properly handled in a timely manner. Poultry houses should be checked regularly for the drinking water and feeding systems to ensure there are no small leaks or small spills of feed. When collecting eggs, try to avoid breaking them. Appropriately adjust the ventilation system of the chicken house to ensure suitable air speed and prevent excessive ammonia levels.

2. Biological control: Biological control of flies involves cultivating the natural enemies of flies in feces. The natural enemies of flies include beetles, snails and wasps. Under natural conditions, there are few natural enemies of flies in feces. Dry livestock and poultry manure is beneficial to the growth of the natural enemies of flies.

3. Chemical control: Chemical pesticides are the most effective way to control flies. Chemical pesticides can not only kill adults but also kill fly eggs and larvae.
