Cluster Fly Loft Fumigation in City of London: what we see locally
Cluster flies are much less common in the City than in suburban London, because they breed in grassland. But they can travel some distance, and buildings near larger green spaces, such as the Barbican, Finsbury Circus and the churchyards, occasionally see flies gathering in roof voids and top-floor windows in autumn.
If you're seeing slow, buzzing flies at the windows of a top-floor flat or office, we can identify them and fumigate the roof space if there's safe access.
Where we find cluster flies in City of London
- Top-floor flats: Flies gather in roof voids above top-floor flats.
- Roof spaces of older buildings: Gaps in old roofs let flies in.
- Top-floor offices: Flies appear at windows on sunny days.
- Buildings near green spaces: Buildings near the Barbican and Finsbury Circus are more likely to be affected.
Our cluster fly loft fumigation service covers the whole of City of London, including Aldgate, Barbican, Blackfriars, Golden Lane, Liverpool Street, Moorgate, Smithfield and St Paul's, with same-day or next-day visits.
