How Will Flies Die in Cold Weather?

The cold temperatures that we experience during the winter season can affect the life of insects. Certain types of insects have evolved to endure cold temperatures while others have developed instinctual strategies for survival. The cold weather may cause a reduction in the population of insects, but many of them still manage to survive and lay eggs in sheltered areas.

Cold temperatures can cause flies to enter a state of hibernation. This process causes the flies to cease movement and rest for a few weeks. When the temperatures return to normal, the flies will resume normal life. The temperature at which flies enter diapause is around forty five degrees Fahrenheit (7.2 degrees Celsius). At this point, the flies stop moving completely and will stay motionless.

Flies collect fat inside their bodies, which keeps them warm during the winter. They also produce antifreeze during their hibernation. Flies that get inside the house are probably from the top storey. If they’ve gotten into the attic through the eaves, they may be looking for a warm place to hibernate. To prevent this, seal off any holes in the eaves and around the home.

Flies are very sensitive to the weather. At temperatures below fifty degrees Fahrenheit, they will die off. In addition, the eggs produced by drain flies will hatch slower in the cold weather. In fact, they may remain dormant until the temperatures rise again.
