Thousands of flies in your loft or windows?
Cluster flies are a seasonal plague in the **Brecon Beacons**. Unlike house flies, they hibernate in vast numbers inside wall cavities and loft spaces of older stone buildings. When the sun hits your roof, they "awaken" and flood your living areas.
Professional ULV (Ultra Low Volume) thermal fogging is the only way to reach deep into the nooks and crannies of high-ceilinged Welsh properties.

Cluster flies (*Pollenia rudis*) move into buildings in the autumn. They are particularly attracted to prominent, light-coloured buildings in elevated positions—common across Libanus, Sennybridge, and Talgarth.

Once cluster flies find a suitable hibernation spot in your attic, they leave a pheromone scent. This attracts thousands more flies to the same building year after year unless treated by a professional.
ULV Fogging Technology
We use high-capacity fogging machines that turn insecticide into a fine mist. This fills the entire loft volume, neutralizing the swarm instantly in areas where manual spraying is impossible.
Advanced Treatment: Ecorec Action Plus
We utilize Ecorec Action Plus, a professional-grade insecticide specifically formulated for ULV applications. It provides:
- Instant Knockdown: Rapidly clears active swarms in minutes.
- Superior Flushing: Forces flies out from behind insulation and timber joints.
- Low Odour: Professional fieldcraft ensures the treatment is effective without leaving lingering chemical smells in your home.
Treatment & Safety
As an RSPH Level 2 Certified technician, David ensures every treatment is safe for your family and pets:
- Exclusion: You will need to leave the treated area for approximately 3-4 hours while the mist settles.
- Window Proofing: We treat the "sun-facing" window frames where flies congregate to prevent secondary entry.
- Loft Protection: We ensure water tanks are covered and smoke alarms are temporarily protected during fogging.
