Mice are everywhere and you can't exterminate them.  The best you
can do is prevent them from sticking around.  Get rid of  ALL
protential food sources, by cleaning the SH#T out of the place.
They need access to the outside, so making it hard to get in is
another good thing to do.   THey can lay doorment for weeks,
so they may be in your van before you got to you camp sight.
