Cluster Fly Remedies
Cluster flies are commonly seen congregating at windows. Although it would seem that the use of window screens might help to eliminate the chances of infestation, cluster flies are capable of entering homes through small cracks and openings in walls and foundations.
It is important to properly identify any infestation before attempting treatment. Pesticide use is not advised prior to proper identification and, once the flies have invaded, will not resolve the problem. If you are experiencing a large infestation of cluster flies, contact your local pest control professional for an inspection and to discuss extermination options for your home.
