This sort of trap doesn't just trap wasps and yellow jackets, you may also catch flies and bees, or other beneficial insects. So, it might be in your interest to find a yellow jacket trap made for the species of wasp that's the most common in your area.

Pouring boiling water or just soap water into the entrance of a yellow jacket nest is one way of killing yellow jackets and rendering their nest uninhabitable. Of course, this particular tactic should be done during the late evening, and measures should be taken to cover the skin in case the colony is feeling particularly blood thirsty that evening. If you're going to use soap water, why not do it with some organic dish soap like Seventh Generation makes. Sure, you'll still be the Tamerlane of the wasp world, but at least you'll be remembered as the environmentally friendly murderer of wasps.
