How to Deal With Flies in Winter
Flies aren’t uncommon in homes, and they aren’t necessarily seasonal. If you live in a warm and humid area, you can expect to see flies at some point. The best treatment for flies involves identifying where they’re living and finding them. If you have a basement, crawl space, or furnace room, flies are likely to be breeding there.
In the winter, cluster flies are particularly problematic. These insects are difficult to kill because they’re already inside your walls. You can seal off these entrances, but this will trap them inside and attract other pests. The good news is that most cluster flies will leave your house once spring arrives. However, you should keep in mind that some may not leave through the access point that they first found, so it’s important to clean up dead cluster flies quickly.
During the winter, cluster flies and boxelder flies are common nuisance invaders. They live in moist conditions and will move into a building to lay eggs. Sealing these areas will prevent cluster flies from entering your home. While these flies aren’t damaging, they can cause trouble.
Some flies are only active during warm weather, and in some cases, they’ll stay indoors all winter. If you don’t want to deal with them, you can always try to keep a few worms outside. They can cause a nuisance for you and your pets. In some cases, however, the flies are merely looking for a warm place to breed.
