Consider patio furniture instead of am in-house-living-room sort of couch. Far fewer places for the bastards to hide, and the cushions are usually tougher and less attractive to mice.
Use mouse traps, and check them regularly. No poison - that just means they'll crawl into the couch before they die, rot, and stink.
And consider installing a good cat, if practical. May not be the best option if you have a lot of chemicals around and vehicle traffic.
If you're rural, it'll be tougher to keep up with traps. In the city, I've found that trapping works fairly well. I use the snap traps that kill the mice - a little nasty, but if you use the no-kill traps and release them they just come right back in again. DON'T use glue traps; they're incredibly cruel and they're expensive. With snap traps, it's over instantly.
I've had great luck with these plastic traps; much easier and safer to set than the old "wire" style, and they don't seem to miss nearly as much.
