Can also be found in Ranch/Farm places, although in this area we have Ace hardware as well as a true Hardware Store privately owned ... we broke down and bought those "get in there and eat this poison" type mice traps when we saw a pile of nut hulls on the battery under the hood of our vehicle. We scrubbed down the interior, set the traps, and promptly bought moth balls to scatter around for a few days before we had to go to town. BTW we put those moth balls in netting (like satchet bags), and hung them around the interior. And yes we were volunteering at a site out in the Countryside ! Never found a dead mouse, but no more nut hulls either ... Moth Balls are supposed to keep cats out of flower beds, and apparently mice don't like them either !
We lucked out with no wire damages.
