Cluster Flies
NO MORE CLUSTER FLIES! – GUARANTEED.
The presence of cluster flies inside a structure can create health and liability concerns, especially in sensitive locations, such as hospitals and food processing facilities. Dead cluster flies inside wall voids, cracks, and crevices may trigger allergic reactions in sensitive individuals and can attract unwelcome pests that feed on them, such as dermestid beetles and carpenter ants.
Known Issues
- Structure Invading
Active Seasons
- Fall

Cluster Flies Treatment Options
One-time Fall Invader Control
Adam’s exterminates cluster flies by applying an EPA proven residual insecticide treatment to the foundation and exterior of your home before the pests congregate and enter your home. All cracks, crevices and any possible entry sites are carefully treated, with particular attention given to the sunny sides of the structure. Treatments are generally done in late August or September. The service is warranted for 3 months.
Premier Fall Invader Prevention
Adam’s premier fall pest service provides year-round control of cluster flies and other “fall invaders.” An EPA-proven residual insecticide is applied to the foundation and exterior of the structure. Special attention is given to potential entry points, such as eaves, doors, windows, any cracks and crevices, and the sunny sides of the structure, typically the S and SW sides. Treatments are generally done in late August or September. The Premier Fall Invader Prevention service is an ongoing annual service, so you never forget to schedule treatment. The service is warranted for 12 months.
