Behavior of Cluster Flies

A number of insects have discovered that heated buildings are ideal for surviving the cold of winter. Such pests include box elder bugs, cluster flies, and ladybugs. As the weather cools in late summer and early fall, the sun warms the southern and western walls of buildings. The warmth attracts these insects to buildings where they crawl inside cracks and stay there for the winter. This would be fine, but during warm winter days, some insects "wake up" and end up on the inside of the building.
 
Cluster flies are actually parasites of earthworms. The adult flies deposit their eggs in the soil and the larvae seek out and live off of earthworms.
