<p>Sorry, I missed the editing deadline. S never mentioned any infestations of cockroaches or silverfish, as I’ve seen in NYC apartments, nor any mice. Outside I would think you would encounter squirrels, which I believe are rodents. 
I would expect that Hanover and the Dartmouth campus might see the occasional raccoon, skunk, opossum, fox, wild turkey, or deer. More rarely, moose or coyote. All of the above are pretty typical for towns in northern New England. Places where there is a steady stream of people walking about are less likely to attract wildlife, and many of the above are nocturnal.</p>
