We have had a HORRIBLE problem with mice all year in our vehicles and equipment. I have big issues in my blinds. Wire harness chewed,fires started by hidden nests. Chewing everything. Yesterday our only working fix arrived . Cab Fresh, expensive and mixed reviews ,though worked for us. They are best in closed areas. Engine compartments closed blinds you need a couple. Monks and squirrels are more challenging. I add balsam oil to the pouches to keep them strong.
