CLUSTER/BUCKWHEAT FLIES

Cluster/Buckwheat Flies
Adult cluster flies, also known as buckwheat flies, are larger than the common house fly. These robust, non-metallic, dark gray flies have overlapping wings and are about 3/8’’ with short golden hairs. These very stagnant, sluggish pests are not destructive but can be a nuisance in your home. If they are crushed, they put off a buckwheat honey odor. When temperatures start to drop at night in late August and early September, these home invaders seek shelter to get out of the cold. They will harbor in the cracks and crevices of your home to hibernate and will come out on sunny, warm days-usually around your windows.
