This may or may not work for you.
Last month I had yellow jackets in my soffits. I mounted a 6 inch muffin
(high speed) fan (Radio Shack) on a 2X4 and propped it up 6 inches from
their entrance. As they flew in and out, they got sucked into the fan and
chopped up. Within a day there were none left. I was than able to climb a
ladder and give the nest a dose of poison. I used a puffer filled with
Drione poison


Interesting option.
