Wood peckers will sound this time of year and commonly use homes for this purpose. Gutters will echo when pecked at and this is exactly what they're trying to accomplish so once they start, they won't quit. You need to set up some Bird Tape or Jumping Spiders where they most frequent. As our online article about wood pecker control explains, once they encounter the Spider or Discs, they'll stay away and reroute their behavior.
