We use what is called an “Adirondack Mouse Trap” in this neck of the woods both in our RV and hunting camp over the winter. Without going into a bunch of detail, it is made with a bucket, some wire, a scrap board, and an empty beer or soda can. A Google search will give you all the details if desired. We bait with peanut butter on the can and use about 1-1/2” of RV antifreeze in the bucket. The antifreeze prevents the odor problem being discussed here. I get about a half dozen mice in the bucket at hunting camp and 1 or 2 in the RV each winter.
