Regarding poison: If they're in the walls or attic they can bleed out and die there and you'll have to deal with the stink until they finally either rot or you tear out a wall to retrieve them. That being said, I use poison in my shed.
My personal preference is for traditional mouse traps checked regularly. Have a piece of 2x4 in hand to quickly dispatch the living. It's your home and you do what you have to in order to keep it sanitary and comfortable.
