Where Do Flies Go During Winter?

Have you ever noticed that house flies seem to disappear during the winter months? How do they manage to virtually vanish in the cold weather and then reappear in full force once weather starts to warm up? Read on to find out.

Flies have a short lifespan of approximately seven to 10 days, and the main goal of the species is to find a food source and breed. When winter is approaching, female flies will seek out a place to lay eggs that hatch into larvae. Flies prefer to stick with dirty areas such as fecal matter or garbage bins for egg laying.

Each female fly is able to lay between 100 and 150 eggs at a time, and the reproduction cycle of a fly allows each female to lay a total of about 500 eggs in her short lifetime. These hatched larvae, commonly known as maggots, consume large amounts of food before protecting themselves for the winter in a type of cocoon. Once warmer weather arrives, the flies will emerge from these cocoons to find food and reproduce.

Large flies that are known as cluster flies because of their tendency to cluster survive the winter through their parasitic relationship with worms. The larvae live in the body of earthworms throughout the duration of cold weather. It is not uncommon for unseasonably warm weather to prompt adult flies to emerge and seek shelter in a building when the cold returns, so some homeowners may have to deal with the unpleasant surprise of harboring flies in the wintertime.

Some pests will seek out a warm place to live during the cold winter months. Unfortunately, heated homes could be a target for insects, rodents and other pests that are seeking winter shelter.
