I use kill traps because mice are an introduced pest that causes damage and spreads disease.

I found kraft processed cheese works best

Knead about half a teaspoon until it’s soft then I press it into/around the bait holder. I don’t sit the bait on the bait holder, it’s really stuck. Then I set the trap. I might mix tiny bits of bacon in the cheese.

I cleared out a large outdoor aviary for a neighbour of about 30 mice using this method.
