Cluster Fly Control in Worksop and Surrounding Areas
Cluster flies are seasonal pests that invade homes, lofts and outbuildings in large numbers, typically during autumn and early spring.
While not harmful, they can become an overwhelming nuisance when they gather in attics, windows and light fittings. Our professional treatments remove infestations and help prevent their return.

Signs of a Cluster Fly Infestation
Cluster flies are often confused with common house flies, but their behaviour and seasonal patterns set them apart. Look out for:
Large groups of sluggish flies clustering near windows or loft spaces
Unpleasant, musty smell in closed or unused rooms
Buzzing sounds or movement behind walls, loft insulation or ceiling voids
Flies returning each year around autumn or spring
Visible dead or dying flies on window sills and in light fittings
Cluster flies are not known to spread disease, but they can gather in huge numbers and leave behind staining, foul odours and mess. If left untreated, they often return year after year in the same areas of a property.

Frequently Asked Questions About Cluster Fly Control
Why do cluster flies come into my home?
Cluster flies enter homes and buildings to hibernate during cooler months. They’re attracted to warm lofts, attic spaces, wall voids and unused rooms where they can remain dormant until spring.
They often return to the same building year after year, making professional prevention important.
Are cluster flies dangerous?
No, cluster flies are not dangerous. They do not bite or spread diseases like some other fly species. However, in large numbers, they create a nuisance, leave stains on walls and windows, and can attract secondary pests such as spiders and beetles. Their presence can also cause distress to occupants.
How do you treat cluster fly infestations?
We use a combination of ULV (Ultra Low Volume) fogging treatments and residual insecticides to eliminate adult flies quickly and effectively.
These treatments reach into wall voids, loft insulation and other hidden areas. Prevention is also key, so we provide guidance on sealing gaps and improving insulation.
Can I stop them from coming back every year?
Cluster flies are creatures of habit and will often return to the same hibernation site annually. While complete prevention can be difficult, sealing entry points, improving insulation and scheduling pre-seasonal treatments can significantly reduce the risk of repeat infestations.
Do you treat outbuildings and commercial spaces?
Yes. We regularly treat garages, sheds, barns, offices, schools and other commercial buildings affected by cluster flies.
Our service is discreet, effective and available as a one-off treatment or as part of an annual pest prevention contract.
