Cluster Flies- This fly is a nuisance pest that will invade your home in the fall as the temperatures drop at night. The fly lays eggs just under the earth's surface. The larvae hatches out and bores into earthworms until they are ready to pupate. They pupate just under the earth's surface and then emerge as the fly. They do not lay eggs in your home, and they are pollen feeders. A Cluster Fly can affect your house from three miles away and in large numbers. No matter what you do, this fly still tries to enter the home following any heat loss in reverse from the structure. The treatment is to apply a product on the exterior of the home to eliminate them as they try to enter, paying particular attention to cracks and crevices around windows, doors, and eave areas.
Multicolored Asian Lady Beetle- This beetle is believed to have entered North America by ports, hitching a ride on products from overseas, and some say they were introduced to naturally control the aphid population. The beetle is like a Cluster Fly, trying to overwinter in heated structures. Control for this beetle is to try and seal up cracks and crevices along the exterior of the structure, but with the temperatures differing greatly throughout the year, applying a product on the exterior of the home to eliminate them as they try to enter, paying particular attention to cracks and crevices around windows, doors, and eave areas.
