Yep, works particularly well on squirrels, too! One of my neighbours caught six (!!!) squirrels over the course of a couple of weeks in her loft using peanut butter in a Fenn trap.
Andy, I do admire your diligence in attempting to catch that mouse alive, but it's really not to be recommended having them using your house as a latrine for over a week, particularly if you've got young kids. The spring loaded traps are humane in that they are lethally effective - the mouse literally won't know what hit it.
