I am in the process of creating my soaping room in a sectioned off area in our large barn (with cement floors), and will be building some drying/curing cabinets or racks. Of course, every attempt will be made to keep mice out of the room itself, but unfortunately, mice seem to be an inevitable part of the farm life. I know mice can be very persistent when they want to. Any suggestions on how to create something that still has air-flow but is also impenetrable to the obnoxious little creatures?
