you can always do what i did in camp…there was a mouse (Charlie) in the bunk, i got a sticky pad from walmart to trap it, and placed it near the sink (Charlie’s home, i think) with a piece of popcorn on it (the kind of kettle corn they sell at hershy park; it’s addictive and i’ve no doubt mice love it as well). Charlie was caught, followed by much celebration. Then one kid shopped Charlie in half with a stick. Of course, you can always get an exterminator, but where’s the fun in that?
We saw another mouse (charlette) a few days later. As far as i know, Charlette’s still there.
