Cluster Flies in Central Arkansas
Cluster flies are a member of the blowfly family and are distributed throughout the United States, except for the states bordering Mexico. Cluster flies will enter homes in the fall and spend the winter months hibernating in secluded areas of homes, such as attics, false ceilings, and wall cavities. When spring arrives, the flies will emerge from their hibernating site and try to leave for the outdoors. Unfortunately, many will get stuck within the home, which can be frustrating for homeowners. In early spring, they are more sluggish and do not fly around noisily like other house flies.
Cluster Fly Habitat
Cluster flies tend to live outdoors where they gravitate towards ripe fruits and flowers. When winter approaches, they will enter homes and buildings to retreat from the colder weather. They will hide in clusters, dark nooks and corners, beneath curtains, underneath clothing in closets, in wall voids, and behind furniture and pictures. When the warmth of spring occurs, the flies’ activity is initiated and the flies will emerge from hibernation inside of the home. Once inside, the flies crawl sluggishly over the walls and often fall into food on the table.
Cluster Fly Behaviors, Threats, or Dangers
Unlike typical blowflies, cluster flies are not believed to be a health hazard because they are not attracted to human foods. While not a health hazard, they are considered an annoyance as they can travel in swarms of thousands of flies. When they seek shelter in the fall, they will often gather around the windows of homes and buildings in an attempt to enter. When swatted, they tend to leave a greasy spot. While they hibernate over the winter, their accumulated excrement can give off a noticeable stench and they may also stain walls and fabrics.
