Insecticide Residual Concentrates
House flies rest on sunny surfaces in the daytime, and have a tendency to come inside or under eaves at night. These areas where the flies are resting can be sprayed with residual or contact insecticides. The flies rest on the sprayed surface and pick up enough insecticide to kill them. When spraying the surfaces, it should be wet enough to the point of runoff, but not enough to form puddles.
