I had a big-ass yellow jacket wasp nest under the eave of the house the other day, so I had to make a trip to the grocery store for the can of Raid Wasp Killer. Now if we had this stuff when I was a kid I just don't remember it or maybe it just didn't fit into my Dad's 'How to Be a Man Training' if it was available back then. His way was, knock the nest down if it was too high to douse and run like hell, then come back and pour gasoline on it after the pissed off wasps had settled back down and regrouped on the nest.
Thank God someone came along with the invention of pressurized 'Death in can from 20 feet away' because over the years the yellow jacketed wasp's attitude has not changed one bit - they still don't like to be fucked with !!
Curious, what are your underrated inventions worth mentioning?
