Plastic owls work, for a little while.
“Scare-eyes,” big plastic balloons painted to look like eyes, work for a little while.
Strips of mylar work for a little while.
A BB gun works forever, but is illegal in most places.
Ultrasonic devices do not work.
Building birdhouses for them does not work.
Filling in their holes does not work.

I take them seriously. Quit giving advice that is probably something illegal in most cities. Quit trying to circumvent the law.

I’m no expert, but the woodpeckers I have observed peck for food and to build nests. They seem to prefer good wood for nests and bad wood for food. Sometimes I have seen them peck on the metal flashing on houses to run bugs out from behind the flashing (that’s very loud!).
In any case, if they peck there regularly, they may be telling you you have wood rot and/or insects in the wood.
TWEET! This board is about fighting ignorance. Thus I challenge you to expose my ignorance. I’d have assumed that in most places woodpeckers could be killed as a nuisance the same as rats. Please prove killing woodpeckers is illegal in most jurisdictions in the US.
They also peck specifically in order to make noise: to signal their territories, attract females, etc. As songbirds sing, some woodpeckers peck. Flickers will make an ungodly sunrise clanging on metal gutters and outdoor lights. So Filmgeek’s problem may have nothing to do with rotting wood or grubs living in the siding.
If you do use decoys to scare off birds, they work best if you shift them around a bit. Birds are smart enough not to be afraid of an owl that never moves. But an owl that’s on the ledge, but yesterday he was on the balcony, and the day before that he was in the tree – will probably be more effective. I use rubber snakes to keep the birds out of my strawberry patch, and they work best when I move them at least once a day.
Big Plastic Owls and Scare-Eyes balloons have been found to be extremely effectice at scaring away birds that go after fruits. Starlings, blackbirds, and various others of that sort. As far as I’ve been abl to find, no one ever tested them against woodpeckers, or claimed that they would work on them.
You can check out the Bird-X site. Bird-X is probably the largest bird-deterrent company around. f anyone had anything on woodpeckers, it’d be them.
I once had a problem with birds of differing types lighting on a branch above my car and crappin it severely on a daily basis. An older neighbor told me to wrap an old section of garden hose aroung the branch above the car. The birds mistake it for a large snake and don’t come around. I have lately used it on our son’s swing-set where they sit and mess up the swings (the birds, not the kids). Seems to be much less, if not completely, resolved.
YMMV
Instead of going to the trouble of moving the plastic owl every day or two, I hung it from a line just a fraction of an inch above a wood board that it appeared to be ‘perched’ on. It would move in the breeze and made it more ‘lifelike’ than a nonmoving sculpture. It kept the pigeons away from the garages at my warehouse for many months at a time, until they finally got used to it. Then I moved it to another spot and it worked again for many months…
Two asides about the slingshot, for circumstances when it is legal. First, there’s no need to hit the birds, much less kill them. Persistently disturbing them usually causes them to move along. Second, I’d recommend using popcorn rather than marbles. Not very effective as ammunition (though not harmless), but makes a nice racket and has the advantage of being biodegradable.
As for your problem, FilmGeek, have you tried an animal control specialist? Will be listed in the Yellow Pages.
