Marc needs to find a wildlife control operator in his area and ask them for a Bird Exclusion Job. We recently did one in Tulsa for pigeons. We lined all the landing surfaces with a low-voltage track (kind of like a Cattle wire/electric fence thingy). If you’ve ever touched a cattle wire, then you know it’s effective at teaching one to stay away. LOL… I don’t know if it would work for woodpeckers, as they seem to be able to land on vertical surfaces as well, but I also agree that there may be a termite problem drawing them in. Since bird exclusion is expensive, although effective, addressing the possibility of termites may be a better option, since if you take away the food source, the birds will find somewhere else to have their buffet. LOL Good luck to you Marc!
