🧵 Why aren’t mice and voles stepping on my trackpads?

I’m doing an experiment right now where we set up trackpads made out of cup up gutters and put a ball of peanut butter and oats in the center on top of a piece of paper with two pieces of felt paper clipped on each side and covered in charcoal and mineral oil ink so that and mouse or vole who comes in will step on the ink and leave footprints on the paper to get to the food ball.

But I’m leaving them up for weeks and not getting any hits, just ants, slugs, and other insects with the balls seemingly untouched and no prints.

What could I be doing wrong?
