This trap is perfect for catching any kind of flying pest in. Deep enough, the bait will not drip out even when swinging in the wind. Make your own attractant: Insert one or two small pieces of raw meat, fish / seafood or wet cat food. (Cooked meat is not as effective). Then fill with any fruit juice to the bottom ring. Add 1 teaspoon of sugar and one or two drops of dish soap. Reassemble trap and hang. When reusing, rinse with fresh water. * Yellowjackets can escape at the very top so a little duct tape will seal them in. *Pro tip – If you set these out early enough, you can catch a queen yellow jacket. Catch her, and you just eliminated an entire colony of yellow jackets.
