Mice or some other small rodent (not squirrels) have decided to take up residence in the roof of our cabin. There is no attic, just insulation between the rafters and an 1.5 air gap between the top of the insulation and the under side of the roof sheathing. I'm not sure how they are getting in there. We screened off the openings for the venting when we built the roof, and near as I can tell from the ground, that is still intact.
Any ideas on evicting these guys without tearing the ceiling apart?
