1. House mice only need a ¼ inch opening to enter a house, according to the University of California Statewide Integrated Pest Management Program. The holes in the heating vent grate pictured above are big enough for a full-sized, adult house mouse to squeeze through. A house mouse can squeeze through cracks in a baseboard, or small holes around plumbing pipes. The best way to prevent house mice from entering your house is to seal all holes.
