I wouldn't say I'm having problems with mice. I live in the country with nothing but fields and woods around me, so they're kind of the norm. This is also why the catch-and-release was silly to try in the first place. I could drop them off in BFE and they'd be quickly replaced by another mouse looking for a warm place (hail hydra). No, I just have to continue to battle them each year and do the best I can.
You can put grates or "hardware cloth" over vents. I did that, and filled in the holes in the walls. I have been mouse free for years now. Behind the house in which I live is a wooded area with a stream. I sometimes see deer and other wildlife out my back window. I am sure there are plenty of mice feeding the owls and other such predators. It was a bit of work covering the vents with hardware cloth and finding and filling all the holes, but it was very much worth the trouble.
It can be done.
