RODENTS v. CANAM | HELP

What are y’all using to repel rodents where you store your CanAm ATV or SxS? I keep my Outty and Commander in a shed next to my camp in the middle of the Vermont woods. I have tired Moth Balls and dryer sheets but rodents still seem to make it into my shed. In the airbox of my Commander they ripped up half of the stock paper filter and used it to make a nest inside the air box. I have found countless times acorns in my Outlanders air box. I also found fur wrapped around the spark arrestor. I also have an outdoor ultrasonic machine going constantly that also strobes and has a loud screecher that can be heard by humans and other animals. I would like to switch to something that might work better so Im not scaring other wildlife away from the area. (Pestisides, natural, chemicals, etc.) Im willing to do anything to keep these pesky rodents outside of my shed. I have just ran power out to there and I really dont want them chewing the wires or the ATV wires. I also dont need more damage done to my engines then what has already been done. I don’t have any great photos of the shed itself. Its pretty old and we just built an extension (shown in outside photo) so we could fit the Commander and the Outlander in the shed. It also used to store my gas pressure washer, lawn mower, chainsaw, weed wacker, and I really cant have any breakdowns as all my machines are used a lot and worked extremely hard. My outlander can’t have rodent issues because in the winter I put tracks on it and groom local snowmobile trails that the trail groomer cant fit in. Im relied on so this needs to be resolved. Please let me know what you guys think. Im open to try anything!
Thankyou!
