That night I heard the rampaging rat, the squirrel soccer team, or whatever was up above my ceiling again. It bangs and clangs and pads and saws! It's directly above my home office. Sometimes it sounds like it's sawing a large piece of wood. Sometimes it seems to be picking up a small piece of wood or a screw and throwing it around. It runs from the office to the laundry room and to the guest bath. Banging on the ceiling directly below it doesn't phase it any more, though this move was followed by a long silence the first time. Sometimes it seems to be twanging wires, playing our electrical system like a guitar. And sometimes I can hear it dig into the wood of the house with it's teeth and pull a little piece off.
After a couple of nights of this, I called the exterminating company and demanded a supervisor. He spent several hours, all over the house. He found another hole under the shingles on a back gutter. He set various traps in the subfloor. It has been quiet...for one night.
Waiting to downsize this animal and again hoping it's done.
