As a rule Woodpeckers drill into trees to get at ants, grubs and other insects which have bored their way into the wood although they do create a nest in a hollow tree in this fashion. They're pretty smart at figuring out what's up with a tree from the timbre of their knocking LOL Anyway, Take your pick what "Woody" is up to at your place. Hoefully he's not after powder post beatles or termites. Sort of poisoning them, I have no idea how you drive off woodpeckers. As to "Phil ", dog fur is the best way to rid yourself of him. As in Caddy Shack, every time you fill in one hole, three new ones appear. If you don't have a long haired dog yourself, find a friend or neighbor that does and offer to brush the dog for free fur. Place the fur around any holes you see and Phil will be off looking for a place far away from Fido.
