I Hear Ya Knockin', But Ya Can't Come In

I'm having a lovely wallow in bed when I hear a rapping on the outside wall of the bedroom, the side that faces the Leaf Lady's house. I know it's not her as she wouldn't give me the time of day. The rapping happened a month or so ago, too.  It's a woodpecker hammering his little beak into the side of the house.

I pull up the blinds and open the window with a bang, scaring the feathers off the little beast.

The little guy or his relative or friend has been over at Prissy's house, too.

Anyone know what to do to deter woodpeckers from boring holes in the side of the house?
