After many years of putting up with daring yellowjackets, I have finally found a product that draws them away from my camp site. Made by Rescue, their disposable yellowjacket trap is totally the bomb. I have never seen a product that actually works better than they claim. This company also makes a disposable fly trap and other traps as well. I bought mine from amazon but they also have them at Lowe's. Walmart and Fred Meyers. So easy, cut a circle around the top, pull up the entry, tie on a string or wire, add warm water to the fill line and hang it up away from your camp site. You need this.
