Did you know that when a wasp is killed, it releases a pheromone that attracts more wasps? Avoid the wrath of other wasps by keeping them away in the first place! The DeWitt Natural Wasp Away works like a scarecrow for wasps. Wasps perceive this decoy as a hornet nest. Hornets are a natural predator of wasps, so wasps avoid areas where hornets are present. Did you know that wasps are actually beneficial to our environment? They help by regulating other pests like aphids, caterpillars, and mosquitoes. Natural Wasp Away keeps wasps away from outdoor recreational or work areas WITHOUT killing them! DeWitt makes Natural Wasp Away from all-natural materials - 70% bamboo and 30% weather resistant cotton. An interior spring coil holds the shape of the product. This product contains zero chemicals. Simply hang it from an eave, porch ceiling, or patio umbrella! ***If you have large existing wasp nests, remove them prior to hanging the Natural Wasp Away.***
