Are Cluster Flies Hibernating in Your House?

Do you feel like you are swatting at flies all year round? Are you wondering why they never seem to go away? Have you ever considered that they might be different types of flies? You could have a cluster fly infestation on your hands.

flys 1Cluster flies make their appearance in the fall months. They tend to fly to the sides of the home where the sun is shining. They do this during both the fall and winter. They are not reproducing inside the home, rather they are becoming more active on the warmer days. They can be seen crawling out of the walls and out of the attics in an attempt to get outside.

So, what do the cluster flies look like? They are a bit bigger than the house fly that you are trying to swat at during the summer months. These flies are gray and have black markings with golden/yellow hairs on the thorax. The golden/yellow hairs make the flies look like they have a golden sheen about them.

How can you be sure that the cluster flies are not reproducing in your home? Unless you have a lot of soil in your home, you’re safe when it comes to cluster flies reproducing. The eggs of cluster flies are placed on the soil. Then, the larva burrow into earthworms. They feed on the earthworms as they hatch out.

Much like Asian beetles and Box Elder bugs, cluster flies are a nuisance pest because they won’t actually damage your home or cause any serious problems. At most, they may leave excrement markings on your windows or walls, but even this isn’t known to be harmful to humans. That said, it is still a good idea to keep the cluster flies out of your home and/or business. If they have already entered, take measures to get rid of them. We can help.
