I have read on here that using plaster of paris and PB mixed into a ball is a good "remedy" for rats, would portland and PB work as well. I have wondered for some time if we had rats in the barn b/c feed had gone missing and we had found the back end remains of a rat in the drive this summer left over from the cats ... anyhoo I saw one tonight scurry across the floor in the coop when I did head count and locked up. Now I need to know how to get rid of it. Thanks in advance
