Lorry sits around foe ages, now its got mice!

I've got a little 7.5t lorry which I use as a race truck, that means it's stood around for weeks at a time.. Anyway I came over to where it's stored today and it looks like the mice have moved in! Little chocolate sprinkles everywhere and some chewed sleeping bags and pillows!
Probably not something regular drivers have to worry about, but anyone else had similar? What did you do to prevent them making the cab their new home, bearing in mind if I set traps they'll be left for at least a week till I come here next..
