A Gnawing Issue
This time of year, even with 12 degree nights and snow on the ground, rodents can be active around structures. Usually, they will exploit and make larger existing openings. A favorite is the opening that may be in between two doors, at the sweep level of an astragal seal. This photo shows a small gap that let enough heat and odors out of it to encourage a rodent to start expanding the opening. You can see a leaf pictured in the gap between where the mouse has chewed it apart. The solution here is to remove these damaged vinyl sweeps and replace them with new, brush style sweeps.
