Your not going to get rid of the woodpeckers, the males peck to attract females...they like your wood if there are bugs in it,,,and some woodpeckers are just plain old dumb.
I have one every year at the beginning of spring till middle of summer. Pecks on my aluminum gutter, man what a racket at 5am.
Concrete siding is one option, the new stuff is pretty durable, and causes a headache for those little critters.
Good luck, I live out in the country...animal life is everywhere.
