Rat snakes In Georgia south of Atlanta @ High Falls. I've had a huge rat snake problem. I have 6 steady laying hens. In the last 3 weeks I have caught 4 rat snakes. Some I haven't caught but I know they've been,because no eggs at the end of the day. Normally I will get 3 to 6 eggs everyday. I put moth balls out yesterday, but as of 2 o'clock today..........no eggs. Does anybody have a proven repellant?
