Cluster flies, or Pollenia rudis, generally make an appearance in autumn as they fly near the sides of the home looking for a place to stay for the winter. They can enter your home in great numbers if they find an entrance. While they will probably not reproduce in your home, on warm days they may crawl out from their hiding spaces looking for a way to get back outside.

Cluster flies are slightly larger than the common house fly and are a dull gray color with black markings and tiny yellow hairs on the thorax, which can give the cluster fly an overall yellow hue.
