We live in a townhouse with a small back yard. Our neighbors have 3 lrg dogs and the neighbors beside them 2 lrg dogs (this makes 5 large dogs in a small space). Although they are pretty good about cleaning up the stinky poo every other day or so, the 2 yards have recently started attracting ALOT of flies, that are venturing over to our yard. We put up a wall of privacy fencing, but haven't noticed a difference. Help!! We have a nice little backyard oasis set up, but the flies are running us indoors!Yuck!
