Cluster flies (or Pollenia Rudis) are common throughout Europe. Cluster flies pose no threat to healthcare nor do they carry disease as they don’t lay their eggs in our food. Cluster flies prefer the environments, created by earthworms.
It’s known that cluster flies lay their eggs near to earthworm’s burrows. Typically the eggs will be left in either soil or dead rotting leaves. Once the eggs hatch the larvae and maggots seek out earthworms. Earthworms provide the primary food source until they are fully grown.
If cluster flies are not necessarily harmful to humans, do they actually pose a problem?
Cluster flies are generally considered to be outdoor flies, however when the cooler winter temperatures begin to fall, cluster flies do venture indoors. Cluster flies have been known to retreat indoors in their thousands, often found hibernation in the attic. This is the reason for their anointed name, ‘attic flies.’
It’s known that cluster flies favour inaccessible places such as inside the cavity walls, cracks and cavities near the ceiling or around windows. Other places that are attractive for cluster flies are basements, or other rooms in the home that are sparingly used. As the weather warms, cluster flies do tend to filter into other areas of the home, which can be an unpleasant experience.
What regions of the UK are mots at risk of an infestation of cluster flies?
Countryside homes are most at risk of suffering an infestation. The expansive countryside area affords places for adult flies to find a comfortable place to rest. Cluster flies are also found in areas with an abundance of earthworms, popular locations include gardens, cemeteries, pastures, parks and fields.
