I wonder if it could prevent mice from chewing into food bags in the backcountry. Not sure what it would incur in terms of weight but could be another type of product instead of the alternatives (odor proof sack, Ursack and hanging).
Bear spray is supposed to attract bears, and the story is they even like the taste - except when it's blasted into their eyes/nose/mouth/lungs. It is a food product. So I would be a little concerned about that.
