Cool-Season Flies. Just when you think you'll get relief from summer flies as the weather cools, you might notice flies that hang around in the winter -- sometimes in large numbers. Although these flies are a nuisance, they don't carry bacteria like house and blow flies. They live in a semi-dormant state as adults in the winter, typically in the upper areas of your home such as a second story or attic. They fly around occasionally, but usually, you'll notice them congregating in warm areas.
