Check the video. I know it's a bit long, but there's a narrative with it, and the mouse really is unique in its ability to avoid being caught. I tried bait blocks, once in a small bait station, and once in a bait station I made by myself with a piece of four-way PVC connector. I tried the bait chunks by themselves, and in a combination I call "mouse bane." He simply wouldn't take them.
Tried peanut butter or bacon in a spring trap?
