Get Rid of Cluster Flies | Remove Cluster Flies

Cluster flies aren’t a health hazard in the same way that house flies are, but they are still a nuisance as they infest homes in such large numbers. Because of this it’s necessary to get rid of cluster flies.

What are cluster flies?

Cluster flies look similar to house flies, however, they behave very differently as they’re sluggish and don’t buzz around. They aren’t a health hazard as they aren’t attracted to your food or waste as somewhere to lay their eggs. They only invade homes when they’re looking for somewhere dry and sheltered to hibernate.

How do cluster flies reproduce?

From late spring and during the summer, cluster flies live and breed in fields. The female flies lay their eggs in the soil. When they hatch, the maggots seek an earthworm host. They penetrate its body, continuing to develop until they become full-grown after two to three weeks. They subsequently emerge and reproduce. Up to four generations may be produced over the summer. In early autumn, they start to look for dry, sheltered places to hibernate over winter such as under loose bark or in hollow trees. They emerge from hibernation in mid-spring. Adult cluster flies feed on flower nectar, plant sap, fruits and other organic matter. They live for three to four years.

How are cluster flies a nuisance?

Cluster flies often hibernate in houses close to open spaces and fields. From late summer they start to gather in large numbers on sunny, light-coloured outside walls. Eventually they find their way inside by squeezing through crevices and cracks around tiles, window frames or under the eaves. They are a nuisance as hundreds of flies form clusters in upstairs rooms, roof spaces, wall cavities or window sash boxes. Unfortunately, cluster flies and their descendants tend to return to the same building to hibernate year-after-year.

What are the signs of problems with cluster flies?

If you have a cluster fly problem you will notice dead, dying or lazy flies around windows or in roof spaces in the autumn or on warm days during late winter and early spring.

How to get rid of cluster flies

Preventing cluster flies from accessing your home is impossible so getting rid of them can become necessary. Fogging the infested and surrounding areas with a biodegradable insecticide is the best solution as it allows the insecticide to penetrate into the cracks where flies may be hibernating. The insecticide doesn’t harm mammals or humans, it’s almost odourless, non tainting and does not corrode or stain.

Dying flies may be seen for up to four weeks after treatment as it depends on temperature and how much insecticide they have absorbed. The treatment will not eliminate the fly infestation but it will kill the vast majority of flies present at the time of treatment.
