Get a cat, about a year old, they will destroy a mouse population, when they get too old to hunt or slow down on the killing get another one and get rid of the old guy.
I'd like to think the old guy has earned his keep at that point
We put dryer sheets in our camper when we store it for the winter. Supposedly mice won't go near it - never had a mouse problem so I guess it works.
won't kill them but it might be a cheap way to steer them toward a trap
