   One can buy micro-encapsulated Diazinon under the name KNOX-OUT at farm
supply stores.  The yellow jackets carry poisoned bait back to their
colonies, where trophyllaxis (mutual feeding) spreads the poison about.

   To exploit a tuna/poison mixture, one must proceed in steps.  First, use
pure tuna alone to build up a feeding frenzy.  Then, switch to some tuna
laced with KNOX-OUT.  Also, one must not too high a concentration of the
poison, or the yellow jackets might avoid the bait.
