I have found that using glue boards work well - the approximate 5"x8" size. Just put some along the wall, as mice tend to travel along walls for some reason. They are cheap at about .50 per board in decent size packages. Warning: My wife accidentally touched one of them and it peeled the skin off her finger when she took it off. I think paint thinner could be used to loose the glue, by she panicked. The glue on them is really strong. Even if you think you don't have a mouse problem, the glue boards will confirm whether you do or not. The only drawback I have found with glue boards is you can only catch one mouse at a time with them (except getting your finger stuck on them, like my wife did).
