What's the first sign of cluster flies in a UK home?

A sudden bloom of adult flies indoors — more than 4–5 a day for several days — almost always means a hidden breeding source within the building.

House flies 8am–7pm; cluster flies sunny afternoons. The deep buzzing of a single bluebottle inside the home in winter usually means a dead animal in a void. Cluster flies are near-silent.

How do I know it's cluster flies and not something else?

When does a cluster flies sighting become urgent?

Cluster of bluebottles in one room with no obvious source — usually a dead animal in a wall or chimney.

Where do cluster flies usually nest or hide?

Bins, drains and lofts. Bin stores, drain stacks, the void around extract fans in commercial kitchens, and lofts (cluster flies) in autumn.

Standard cluster flies jobs carry a 30-day guarantee; established cases usually 60–90 days. Any return visit inside the window is at no extra cost.
