Yellow jackets are gone, I went with the pros. It was interesting to watch them do their work. He suited up in his bee gear got right at the wall they were in and started pounding on the wall, out they came. This guy was not afraid at all. The yellow jackets were all over him. He used something they call dusting or fogging. It was a white powder and all he did was spray them with it. I guess it gets on them and the carry it into the nest and spreads it all over, they were gone in less then a day.
