Sorry 'bout that - pretty easy to figure how to do things in / to someone else's house - much like spending someone else's $$$. Mice aside, I think you just described a place I would love to get my hands on. Wow - 300 years old - that sounds very cool. Is there a way to focus on / seal up the living spaces - that would be a great part of the battle won. Dirt floor in the crawl would be a real challenge. Sounds like you have a big scope and limited options. Maybe you can adopt a couple of barn cats? Good luck with the critters...
No worries. I actually like an org called Farm Sanctuary so I don't relish killing them either. I'm ok with them outside but not in my house.
