Cluster Fly Control in Newcastle, Sunderland & Durham | Pest Shield

Cluster flies may look similar to house flies, but their behaviour is quite different. Unlike house flies, they are sluggish and don’t buzz around. Cluster flies typically invade homes when seeking a dry and sheltered place to hibernate. They do not pose a health hazard since they don’t lay eggs in food or waste. Pest Shield provides expert cluster fly control Newcastle, Sunderland & Durham, helping you clear infestations quickly and effectively.

Why Choose Pest Shield for Cluster Fly Control Newcastle?

Cluster flies hibernate in large groups, with hundreds clustering in upstairs rooms, roof spaces, wall cavities, and window sash boxes. In early autumn, they gather on sunny exterior walls before finding their way inside through cracks, window frames or under eaves. Once a site is chosen, they return year after year due to genetic memory. Our cluster fly control Newcastle service ensures your home or business is protected long term.

Signs of an infestation include dead or sluggish flies around windows or in roof spaces during autumn, or activity on warm days in late winter and early spring.

Preparing for Cluster Fly Control Newcastle Treatments

• Ensure interior walls, ceilings, windows, and frames are clean and dust-free.

Cluster Fly Control Newcastle – FAQs

How do cluster flies get into houses?
Cluster flies often enter through small cracks, gaps around window frames, roof tiles, or vents. Once inside, they head to roof voids, wall cavities, and upstairs rooms to hibernate. Our cluster fly control Newcastle service targets these entry points and hibernation areas.

Are cluster flies harmful?
No, cluster flies don’t carry disease in the same way house flies do, and they don’t lay eggs in food. However, in large numbers they become a nuisance, and dead flies can attract other pests. That’s why professional cluster fly control is recommended.

When is the best time for cluster fly treatment?
The most effective time is early autumn, when flies first gather on sunlit walls and before they settle into lofts and cavities. Treatments can also be carried out in winter or spring if activity is noticed.

Can I prevent cluster flies from coming back?
Cluster flies have a strong genetic memory and often return to the same property each year. While sealing cracks and gaps helps, professional cluster fly control Newcastle with residual sprays or fogging is the most reliable way to stop repeat infestations.

How long does the treatment last?
Residual insecticides remain active for 1–3 months, depending on conditions. You may see dying flies for several weeks as the treatment continues working.
