Preventing mouse(?) damage to a B&S twin

I've been working on a puller type garden tractor. Originally it had a Kool-bore 18 hp opposed twin in it. A neighbour gave it to me a few years ago and it quickly became my favourite as it could do so much work. When I got it, it was smoking a bit and leaked some too. I changed the oil often to get as much life as possible out of the old girl. The engine was quite oily/dirty. Finally I found a nice 16 hp Vanguard to give the opposed twin a well deserved retirement.
I store my tractors in substantial portable shelter and have found that something has built a nest in the clean Vanguard(I never have had a nest in the opposed twin). I've included a photo of a nest that was built in less than 4 days. I also have a lawn tractor with the identical engine and it too has had two nests built in it. I suspect that the rodents like the cleaner environment of the Vanguard.
I easily found the two nests in the lawn tractor as bedding was seen in the flywheel screen. Evidence of the nest in the puller tractor wasn't visible. That's the problem. I could have easily motored off and cooked the engine.
Now I need a solution. I can't have a cat as this is at my cottage and I'm only there for short intervals. I won't use poison I have a dog and won't chance hurting her. The odd snake would take care of a few but they are only there in warmer weather. I can't use a plank leading to a pail of water as it would freeze in colder temps and antifreeze is out because of the dog. Good old fashioned mouse/rodent traps would get a few but as I said, I'm not there for long periods.
Is there a cylinder temperature monitor that I could install on both cylinders?
I also have a compact JD diesel an it too has fallen prey to rodents as they ate insulation off of a wire harness where their nest was.
I've tried everything that I know of and it isn't enough. Any ideas on dealing with my problem will be appreciated.1-DSC07849.jpg

Considering it is about a 5 minute job to remove the blower housing, that would be the easiest thing.
The rodents only set up camp there to be safe from their preditors so deprive them of the hidy hole
!/4 " drive sockets will get in to undo the 3/8 fasteners.
Or one of those screwdriver bit ratchet drives will work a treat as well.

A thing I learned awhile back, ... take a couple old "socks" and pour a bunch of mothballs into them, animals can't stand the odor from the Naptha, and I think I've been told even cats & dogs can't stand it either, just place them on your mower near the engine, hope you can handle the smell too .. :thumbsup:
