Cluster Flies

"The Cluster Fly . . ." The adult cluster fly may be mistaken for the housefly at first - but may vary in size, some larger and some smaller. They're noisy and awkward. They fly into lights and windows, often colliding with objects, like lamps; at times falling to the floor spinning on their backs buzzing loudly, until exhausted. This fly has a nonmetallic, dark gray color. The thorax has golden hairs, and stripe. It is also typical of the fly to occasionally overlap its wings when landing.

The adults lays eggs in the summer on the soil of lawns, fields and gardens and completes the life cycle of up to four adult generations each year. The larvae of the cluster fly is an earthworm parasite, thus the cluster fly is found wherever the earthworm is found.

Cluster flies are one of the most common pests to invade rural homes and estates. These pests live in treed and grassy areas in the summer and seek shelter in your home for the fall, winter and spring. They will usually get into your home very quietly, crawling through tiny openings in fascia, soffit, windows. doorways and roof vents. Several hundred, even thousands of flies may seek shelter in your home, especially in the attic and windows exposed to the warmth of the sun. They often "cluster" together. This is how the name "cluster fly" came to be known.

The first warm days of spring cause cluster flies to reappear. This nuisance pest will stain walls, carpets and furniture and create discomfort in your home. The accumulation of dead flies in the walls and on the floor attract dermestid beetles (Larder Beetles) and small rodents which feed on their carcasses.

Our “Home Service Program (HSP)” is highly successful and will eliminate and control your cluster fly problems. The HSP Program will also control invaders such as; Pine seed and boxelder bugs.
