In my case, I use the life trap traps - the bait I'm talking about is dog kibble. Although I may have to change the kibble since it doesn't seem like the mice like them - one or two chews, and they leave them alone. After I trap them, I let them go a few hundred feet into the grove - waste not, want not, something will catch, and eat them. I won't use poison - had a neighbor who wanted to get rid of ground squirrels and started just tossing poison all over the place. One day I noticed my dog carrying what looked like a blue stick around - it was the poison. I mentioned it to my neighbor (city folk), and since they had dogs as well, they stopped using the poison, instead they just shot the squirrels.
