The Yellow Jacket Control Trap gave me some hope that I would be able to do at least something about the scads of yellow jackets all around the house. Well, the yellow jackets completely, and I mean completely, ignored the trap. It's only been successful in trapping a few gnats, but that's it. I do not recommend getting any hopes up about this trap doing anything to mitigate a yellow jacket problem. One of the most annoying features of the product is the yellow jacket graphics printed on the outside of the bag which fool you into thinking, only for a moment, that it may actually be working.
