Gotta go with Dogfish on this one. Watched a buddy do the shop-vac thing to a massive next of yeller-jackets living in the siding of his house. As Dogfish said, it was rather entertaining listening to them get sucked in the shop-vac at a furious pace....until they were all gone.

Unfortunately, he must have missed the part about dropping a bug-bomb down the hose, as a whole bunch of pissed off yellow jackets escaped the shop-vac when he opened it up days later.

Most were dead though and he never did get stung.
