Generally, woodpeckers make nests during the spring, lay eggs, and after the young are out they abandon the nest. So, this being late summer makes me wonder about their motives. Since some woodpeckers migrate, it would be helpful to find out exactly what kind of woodpecker is doing the damage. Attic spaces are not preferred nesting areas. Woodpeckers usually make deep pocket-like nests. If the action is nesting for the winter, you may succeed by building them a deep pocket bird house and using it to cover the hole in your wall. Pecking is eithernesting, food foraging action, or territory marking. I have a hard time believing you have enough bugs in your siding to be of interest to a hungry pecker.
Most visual deterrents are less than 50% effective. This would include plastic snakes, mylar ribbons, rubber owls, mirrors, and so on. The "scare eye balloon" is a little better - maybe 60%. You can usually find these at a garden center.
Recordings of predators are effective for only a few days.
Ultrasonic and electronic repellers are not effective at all.
There is a device designed for the garden that could be adapted to this job. The device is called a "scarecrow," I think. It hooks to the garden hose, has a sprinkler mounted on top, and takes a 9 volt battery to operate a motion detector. When the detector is tripped it turns on the sprinkler. The sprinkler motion can be controlled.
Good luck, these guys are a real pest when they like your house.
