CLUSTER FLIES: DIY Tips for Prevention
Cluster flies can be a frustrating fall nuisance, but these few simple preventative steps can help keep them from settling into your home or business:
✅ Seal cracks and gaps around windows, doors, siding, and foundations to limit entry points.
✅ Check weatherstripping and door sweeps for damage, replacing them as needed to keep flies from slipping inside.
✅ Install or repair window screens and make sure attic vents are properly screened.
✅ Use a vacuum to remove any cluster flies that have already made their way indoors.
✅ Schedule professional preventative pest control treatments before cluster flies begin seeking shelter for the winter.
A little preparation can go a long way toward avoiding unwanted pest problems!
