I have something that is in the wall or ceiling of our bedroom. It is active at night and sounds like it is either chewing on wood or nuts... a gnawing sound. When I pound on the walls it gets quiet and then starts again when I quiet down.
What should we do? Our house is brick with a big metal soffit, not sure how anything could get into our place, we are suburban with lots of trees around and often see squirrels and chipmunks in the yard... also lots of birds.
