Last year we had mice for the first time in 27 years camping...luck ran out. Our solution was to place 4 old fashioned spring loaded mouse traps in outside storage compartments with peanut butter. Worked overnight. Two dead mice - have not had any since. BTW, there were droppings in bread drawer and broom closet also. They find their way around the motorhome. We also tried the newer "hockey puck" type traps, thay did not catch anything - but they are still in our compartments along with the four old fahioned traps. Good luck.
