Being a resident of Wyoming, I first saw these spiders in action at Signal Mountain Lodge at Jackson Lake. Having purchased them this past summer for my cabin in Bondurant Wyoming they worked like a charm. Not only do they detour the pesky woodpeckers and flickers…They provide hours of entertainment for family and friends as well as the unexpecting salesman. …Hours of family fun and practical ta boot!!! The kids and dogs enjoy the surprise as well.
