We live in a heavily wooded area. When we moved in we noticed that the north side of the house had some holes from woodpeckers. We filled the holes and repainted, and for most of the summer didn't notice any additional damage. But then I looked up the other night, though, and there are once again sizable holes in the wood siding. How do we get rid of the wood peckers or discourage them? The idea of hanging pie tins from the eaves is not an ideal choice, aesthetically, and I'm not even sure if would work. Thanks!
