almost everyday in the afternoon, there are at least 2 flies getting into the house even with the windows and doors shut. no matter how many we spray down, they always come back. any ideas to help me?
Have you noticed any unusual odors, I'm referring to a possible dead animal. If you have a fireplace open the damper and check for odors. If you have a crawl space under your home check there also. Another source may be your attic.
