A few years ago I had what I thought was a good idea. I had a yellow jacket nest in the ground at the bottom of a ditch about three feet below a headwall. I thought pouring some gas down the hole after dusk would do it and it probably would have all by itself. But I needed to go one step further and I stood on the headwall and dropped a match into the ditch. It was very humid and the gas fumes hung at the bottom of the ditch and the whoosh when the gas lit up scared me to death. Best laid plans and all that.
