The BioCare® Yellowjacket and Wasp Trap is a slim-jar trap, which safely and efficiently catches Yellowjackets and other wasps by baiting and capturing them in the jar. This trap is more effective because it lets a few insects escape and return to the nest - they then revisit to the trap, bringing more wasps with them right into the trap! One Yellowjacket lure included. Made in the USA!
