You could always try the Tremors (Spelling?) approach. Get some thick clothes, goggles, and a ski mask, and douse eachother with fire extinguishers. If I remeber correctly, bees, much like other insects or spiders judge what to sting based mostly on heat.
Wait, we have tons of vets and people serving right now, but we don't have any smoke grenades?
Ahhhh! Terrorist Bees! Sounds like a job for.... DALE GRIBBEL!
