What Are Cluster Flies?

Cluster fly swarm

Cluster flies are small, dark grey flies with golden hairs on their thorax and a black and silver checkered pattern on their abdomen.

It’s easy to identify cluster flies, as they’re smaller than other species of fly, such as the house fly, and they’re usually found in large groups, which is why they’re called cluster flies.

Adult cluster flies can grow up to 10mm in length and have transparent wings with distinctive veins.

Due to their small size, they can be difficult to see up close when alive, but you will probably see dead flies littered around window sills.

Also known as attic flies or Pollenia Rudis, cluster flies tend to be a problem in Spring and Autumn when they seek warmth and shelter.

Usually, cluster flies enter homes through large windows or doors and will come and go as they lay eggs in the soil outside.

Because of their preference for earth or animal dung, cluster flies can contaminate human food and cause cleanliness issues, so it’s important that you work with the experts at Briarqest to get rid of them fast.

How Briarquest Removes Cluster Fly Infestations In Scunthorpe

It’s common to find cluster flies coming indoors in Winter when they’re looking for somewhere to rest. As the warmer weather arrives in Spring, the insects will suddenly appear in a cluster, looking for windows and doors to leave through so they can go outside to lay eggs.

Often found in roof eaves, around upstairs windows and near exterior walls, cluster flies can be difficult to remove. Thankfully, Briarquest uses a range of innovative techniques to get rid of cluster flies, their larvae, also known as maggots, and their eggs. Some of the ways we remove cluster flies include:

  • Ultra Low Volume (ULV) Fogging: One of the most effective ways to remove cluster flies is using a ULV fogging machine. Fogging with these machines reaches all the nooks and crannies in your property, which is particularly useful for hard-to-reach areas, such as large roof spaces.
  • Supplying Electronic Fly Killers (EFKs): EFKs are common in commercial settings, such as restaurants. We supply innovative, top-quality EFKs that use the exact wavelength of UV light that scientists have found attracts flies. Once inside, they can be lured onto a sticky pad or electric grid. Our team supplies, fits and maintains EFKs that will help manage any cluster fly infestation.
  • Rural Cluster Fly Removal: Because cluster flies are often found in rural areas, we also offer specialist fly treatments for household waste sites, pig units, poultry farms and equine facilities. Cluster flies are often attracted to animal waste or dead/decomposing carcasses that pose a public health risk. Flies leave these premises and then land in someone’s kitchen or on a person’s food, causing significant contamination and spreading disease.


Once we’ve removed the cluster flies, we can help to prevent cluster flies from returning by proofing any potential entry points. If you’re ready to eliminate cluster flies from your Scunthorpe-based home or business, contact us today.
