Your mouse will only move from room to room if there is a way for him/her to get out. For example, one of my Robo hamsters escaped weeks ago and he went underneath the door as there is about a 1inch gap. I didn't see where he went but my house is a maze of hidey holes!

Probably best to put the trap out of the way from sight...the mousey might not venture out into a large space in case it gets caught!

Good luck with finding your meece!
