Go on YouTube. There are various DIY catchers and you can also buy them that are buckets with water, a ramp and a flip floor. It can catch LOTS of mice everyday and they drown, so no longer alive. They really work. And cheap.Granny I have a small box trap for mice that I got from agway for $15 I think. Maybe if you use something like that baited with feed and put all your feed and feeders away at night they will pile in the trap. I've seen ten at a time go in them. They are still alive so what you do with them after that is up to you, but they will be out of your feed at least ! I know kids that like to feed them to local bass ponds.
