I have a small skid steer I park on a cement patio on side of my garage. no room inside garage. Eveytime I go to use it mice or a mouse is scooting out of it. today I started it with air cleaner off ( had to prime) and dead mouse smell filled the cab..end lots of cotton debri flew out the tube going to housing covering cylinders ( onan). I've tried those packets that smell like peppermint..no help. Anybody find something that actually keeps them away? They must like the oil smell or something. I could put in garage but then the big scag mower would have to sit out..have same problem.
