We have a camp on Winni and every fall close it up, including the annual rite of spreading mothballs. Most of the time it works -- but only where the mothballs are spread. One year we forgot to put them in the trundle bed and in the Spring found many droppings and nesting materials -- everywhere else was untouched -- including the top portion of the bed.
This year we closed the camp later in the season -- late-October. By the time I opened the linen closet to relocate the towels for the winter, I found droppings and nesting material! We hadn't been to the camp in 2 weeks -- they certainly didn't waste any time!
