You can utilize a fly light or two in the home to attract the flies that are coming from the attic. A great option would be the FlyWeb Plus which plugs right into an outlet and doesnt take up much space or stick out like a traditional fly light would. The flies will be drawn to the light and get stuck on the glue board behind it. Keep in mind this is only a temporary fix since the source of the problem is not being elminated. You may want to enlist in the help of a contractor or pest company in finding any holes that may be allowing acces for rodents/birds or anything the flies could come through and closing those areas up.
