Best mouse trap I ever saw was a plastic 5 gallon bucket with rolled barley & molasses in the bottom, a piece of wooden snow fence slat at about a 30 degree angle up to the outside top edge from the floor. I think my dad caught something like 17 mice the first night with it. It did reduce my fun of shooting mice with a pellet gun while I was working in the garage. Now I put some bar bait like TomKat in a canning jar with about a 1" square cut in the lid. Lay the jar on its side. Mice go in & eat, wander off to never be seen again. I have them scattered around the yard next to outbuildings, lumber pile, etc. I even taped one on top of the inner fender under the hood of my pickup. I haven't had mouse problems since then.
I once took my old lion hound out for a walk on a leash. She was busy dying of cancer. We were walking across the pasture. She dropped her head & took off. I could tell she was on a track. I ran with her to the end of the track where she stopped & started eating something. I pulled her back & saw that it was pink, wiggly jelly beans. She had tracked a mouse to the nest & was eliminating the babies. Poor old Maggie died later that winter. She was a true hunter to the very end.
