This WAS mice country till I convinced me neighbors to stop killing the snakes. I had a terrible time keeping the vermin under control. A cat didn't wrok, neither did two cats. The problem got worse. I got rid of the cats, took them down the road and set them out, and the snakes came back. Lo and behold, after me neighbors quit killing them, the rats and mice went away. Sure, there were a lot of snakes around, with so many mice feeding them, but they never bothered me, the cows, the horses, the goats, the chickens, or any of the other animals. I taught the dogs to leave them alone, and we haven't had mice trouble since.
