I'm going to kill this squirrel

For the last couple of months, a squirrel has been trying to drive me crazy. Seriously. It scuttles along my roof before settling in a particular spot where it scrapes and scratches. Imagine nails across chalkboard meets dragging chair across the floor and crunching chips.

Not cool....at all.

ANNNND it's rude self, has the nerve to wake me up every morning for the past week BEFORE 7am, with this nonsense!!! Then, it comes back throughout the day, doing it whenever it wants. It has even become stubborn. When I hit against the wall it stops, waits, does a little scrape, I hit it again, it repeats, and then keeps doing it as if to say "ha ha! you can't do anything!"

The squirrel must die.
