Normally, I use the “Just one Bite” bait.
But I had set a piece out about 1/2 cubic inch and the suckers stole the whole thing!
So I set the trap to see if I was dealing with Ratzilla or something, and it looked like a healthy, average size adult female gray mouse, nuthin spectacular.
When I use traps, I use the Woodstream quick set traps. Very easy to set and use, you never even have to touch the mouse.
I'll have to look for some of those. Too many of mine in the garage have too heavy of triggers so the mice just use them for peanut butter buffets.
