This involves mice so it's still slightly ON topic Last night we were watching TV it the basement and started to hear noises. We turned off the TV and low and behold it's a scratching noise inside the wall up high at the ceiling. I stood on the sofa and put my ear against the wall and I could hear something running. I have to guess that it was a mouse/mice. That wall is an exterior wall. How do I get it out of the wall?????
