How Can Flies Die From Cold Weather?

Flies are sensitive to cold, and they may die in cold weather. However, they may not die immediately – they can survive for up to four weeks in cold temperatures. However, if the temperature drops to 32degF, they will most likely die sooner. The reason for this is that flies have evolved to survive the cold by slowing down their life cycle. As a result, they take two to three months to grow from larvae to full-grown flies.

Flies can survive freezing temperatures, and scientists have demonstrated this in dissecting a fly’s body. This proves that the insects store fat in their bodies. Moreover, their metabolism is reduced, so they do not die in cold temperatures. During the winter, flies produce glycol, which keeps their bodies warm despite the freezing temperatures. If you want to avoid dealing with these annoying insects, you must make sure your fridge is well-insulated.

Flies can survive in cold temperatures if their eggs and larvae are protected. If they are kept in the protected conditions, they can even survive the winter. Even mosquitoes are hardy enough to survive in cold temperatures, and can even hibernate as larvae in ponds and pools. Once they hatch, they wait out the cold season and emerge again in the spring.

Cool-season pests like cluster flies migrate into buildings during the fall and winter. The number one place where they can enter a building is the air vent. You can prevent cluster flies from entering your home by installing insect screens.
