Mice & Small Gaps

Our guide puts it plainly: when the nights turn cold, mice go looking for a warm place with food in it, and they walk in through gaps you've never noticed. If a pencil fits in the gap, a mouse fits. Our Mouse-Gap Pack has 2 rolls of copper mesh, each 5 inches wide and 30 feet long, to pack tight into small openings and seal over with caulk, the way the guide shows. It comes with our printable big-print "Walk Your Walls" card (PDF, by email) and the 46-page guide, which starts with walking your walls and the pencil test. With the Before-the-Freeze Pack, both are $44.99.
