Kent, they have taken the bait without getting caught. I have used both apples and peanut butter. I don't like the idea of poison, but I did try some of the pellets balled up in peanut butter and put down the holes. Either they didn't eat it, or it didn't work.
I found some info on line about baking soda mixed with corn meal or flour. Anyone ever tried that? At least it isn't toxic.
