Vida - what sort of "neighbors" do you have? I ask because you mention using the predators. We live rurally, but every single place around us has some form of livestock. My concern being that I could control our little two acres but that doesn't do much good if the neighbors field next door is a breeding ground for flies that will buzz on over to our side of the fence. The next three places to our right all have multiple horses and right across the road is a large field of cattle.....flies galore.
