This is the slim-jar version of the original The Oak Stump Farm Yellowjacket Trap, which safely and efficiently catches yellowjackets and other wasps by baiting and capturing them in a transparent 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! Oak Stump Farm Yellowjacket Traps are reusable, non-toxic and safe for the environment. Case of 24 traps are shipped pre-packaged in an attractive shelf display.
