The patented Dead Inn Stink Bug Trap is being used by the USDA, state agencies, and universities where stink bugs are a concern. This pesticide-free trap uses pheromone technology to lure all stages of nymphs and adult stink bugs. Stink bugs crawl through the center opening but can't get back out. One lure lasts 5-7 weeks. Trap is 17"T x 6-1/4"W at the base. Not for use indoors.
