I thought I had caught THE mouse in my house. Wrong. Now I hear another one. I sleep in a back bedroom. He seems to run from the back wall, through a side wall which is next to a garage, and then, turns a corner and runs through the bearing wall next to the headboard of my bed. He sounds like he's in the ceiling above the second floor. (I have a finished attic above that).

What's puzzling is that, since it's a bearing wall, the ceiling rafters run perpendicular to his path!. How is he managing to do that? I have pictures from when the house was built. There is a 14-2 romex passing through this bearing wall, with 3/4 inch holes bored along its path. But there should be NO ceiling wiring. I can understand a mouse running front to back (of the house), but from side to side?!?!?

Should I try to get some "Great stuff" to spray into the wall adjoining the garage? (This sems to be the entry point)?
