I had a bad mouse problem in my run. I have a camera in the run, (chicken tv), the other night I watched about a dozen or so mice running around and chowing down on the chicken feed. I set out about a dozen traps, including bucket traps. Didn't catch a one. Just ran around them and jumped over them. After looking on the net, found that mice don't like mint. Peppermint Extract mixed with water and sprayed around the feed area works wonders. First night only 3-4, running around, nowhere near food. Second night, only one, still not near feed stations. Third night, I saw one run by the camera and was never seen again. Im gonna continue to use this at night when I lock my babies in. I'm not saying that it will work for everyone, but it works for me.
