Spray foam insulation would solve the rodent issue probably right?

Spray foam releases more CO2 than it saves over its lifetime, is a pain to work with for subcontractors, and is also toxic and will most likely be looked at like we do asbestos now in a couple decades.

And I haven’t even mentioned how it traps moisture against your framing causing rot after only a few years.

No. They dig through that stuff too. Sealing the holes, bait stations around the area, cats, etc.. Those things keep em out.

Spray foam is environmentally horrific. The expansion agent used in it is really freaking bad. White foam uses a different expansion agent that is exponentially less damaging.
