Pest Control - Cluster Flies

The adult is about 6mm long and has distinctive golden hairs on the thorax (chest) area.  The flies live outdoors and the adults feed on nectar from flowers.  The fly lays eggs in damp soil and rotting leaves and when the eggs hatch, the larvae hunt and destroy earthworms before hatching into an adult fly.  They do not breed indoors and they are not thought to carry any diseases.  However, in the autumn, the flies look for shelter and will hibernate over winter.  They will shelter in lofts and sometimes will invade the living space of a house.
