I use the stinkiest dryer sheets I can find. I use them in my camper, snowmobiles and anything that sits for longer than a month at a time.
Others use moth balls, but I can't stand the smell....and dryer sheets are easy to remove from the mufflers and sit right flat in my air cleaners.
Good luck.
I've used aluminum gutter cover mesh to block access to air filters and wrapped wires with it to stop mouse damage. I use it in the grill of my cars to keep rocks from the road from damaging the condenser in front of the radiator.
