How to Get Rid of Cluster Flies in Your Loft in Ashford
If you're noticing slow-moving flies in your loft, windows, or attic in autumn, you may be dealing with a cluster fly infestation. While not dangerous, they’re incredibly frustrating — and hard to get rid of without the right approach.
Here’s what you need to know from the experts at Pest-Mate Pest Control.
What Are Cluster Flies?
- Cluster flies look like houseflies but are slower and gather in groups in:
- Lofts
- Window frames
- Wall voids
- Attics or barns
They hibernate over winter, returning each year unless treated.
Signs of a Cluster Fly Infestation
- Flies gathering on loft windows or around light fixtures
- Dead flies on sills or attic floors
- A musty or dusty smell
- Clusters around south-facing windows
How to Treat Cluster Flies
- Fogging treatment in the loft (kills hidden flies)
- Residual spray in entry points and cracks
- Sealing gaps around loft vents, fascias, and window frames
- Fly traps or fly paper (only catches a few)
- DIY sprays – often can’t reach hidden areas
