About cluster flies in Essex homes
Cluster flies are larger and slower than house flies. In autumn they gather in their hundreds or thousands in lofts, roof voids and wall cavities to spend the winter, often returning to the same homes year after year. On warm days they wake up and drift into bedrooms and around upstairs windows.

Cluster Fly Loft Fumigation: 5 frequently asked questions
Why do cluster flies keep coming back every year?
Cluster flies are drawn to the same buildings each autumn, especially homes with sunny, south-facing walls. Treating the loft each autumn keeps numbers down.
Are cluster flies harmful?
They don't bite and they don't breed indoors, but large numbers are a real nuisance and dead flies can attract other insects.
Do I need to leave the house during loft fumigation?
You don't usually need to leave the house, but the loft must stay closed for a few hours after treatment. We'll tell you exactly when it's safe to go back up.
When is the best time to treat cluster flies?
Autumn, when the flies are gathering in the loft, or a mild winter day when they're active. Treating then clears them before they spread into the house.
Can I just vacuum them up?
Vacuuming removes the flies you can see, but most hide in gaps in the loft and roof. Fumigation reaches them where they're clustering.
