I came home today and heard some scratching going on inside my chimney and found some twigs in my fireplace (the flue is supposed to be closed). Apparently there's a squirrel or some other critter trying to make a nest in there.
Background: a few weeks ago I heard this critter scrambling around in my chimney and called a critter company to remove it. When they showed up, the guy looked around my house, went into my attic, and peered into my chimney, but says he didn't see anything (still cost me $80 for nuthin'!!). Well, the critter is back. I have no idea how it gets in and out of there.
How do I get rid of it? Should I start a fire?
