The Beee Free Wasp Deterrent is a natural, non-chemical solution to your wasp problems. Simply hang your Beee Free in an area that is frequented by wasps, yellow jackets, or hornets and the territorial insects will detect an existing nest and flee to another area. Wasps are very territorial and will not usually build their nests within 200 feet of another nest. Keep your Beee Free up throughout the year, and you will discourage wasps from building nests in your backyard. Each package comes with 2 simulated wasp nests.
