We used "em" and railroad flares to dig up yelloe jacket nest. Light it and lstuff it in their entrance hole. Throw a scoop of dirt on top. The fumes would knock the jackets out. We'd dig "em" brush off the jackets and put nest in a paper sack. At home we'd put the sack in the freezer for a short time to stun any jackets we missed. Then we'd take the nest out and remove any jasckets we missed. Yellow jacket larve makes great bream bait.
