We have a covered front porch and the flies are terrible. We have to run in and out of the house so they don't get in. Seems I am always yelling to the kids "shut the door, quick!" We use fly predators on the property and while we are having a worse than usual fly year and they aren't as effective, there aren't too many flies out where the animals are. They are all congregated on the front deck where it is cooler and trying to sneak in the house where it is much cooler with the AC on. Any suggestions on what to do to get rid of them? Thanks!
