    My own experience has been that gasoline does a better job if you _don't_
set it ablaze.  Left in liquid form, it vaporizes, and the vapors penetrate
downward into the nest, doing a fair (but not great) job of killing yellow
jackets (only thing I've tried it on).  If you light the vapors, what doesn't
immediately burn gets sucked upwards into the flame, and doesn't do its job down
in the bowels of the nest.
 
    However, gasoline poured into the ground is environmentally unacceptable
nowadays.  The shop vac sounds like an interesting alternative (but _two
weeks_?)
