Bought a small farm and was getting it cleaned up. Discovered a yellow jacket nest next to the well head. Could not use chemo and tend towards organic anyhow. Old timer told me once that You should at night dump a bucket full of water with dish soap down the hole and put the bucket over it . Come back in the AM and they will all have soap soaked wings be unable to fly and you could just stomp them or burn them. So I did just as he said. Only problem was I forgot about it until 2 pm the next day when I saw the bucket as I walked by. It was August and close to 100 degrees out. I had my two labs who worked the farm with me. We walk over and I kick the bucket over and the jackets exploded in a cloud. I ran left and the dogs went right. I got hit on the back of my arm and that was it. I stopped running when I heard the dogs yelping, they were running fast and trying to tuck their butts under themselves so far it looked like their asses were going to pass their heads. The jackets had stung my chocolate so bad his head and face swelled up the size of a five gallon bucket. Until the day he died he would shy at any insect flying near his head. We kill 50 or more nest a year on the various barns , it's my sons job and he has become quite creative but the bald face hornets are still a challenge.
