I was mowing the lawn yesterday when I discovered a nest of yellowjackets. And when I say "discovered," I mean I ran over their nest with the lawnmower. For those not familiar, yellowjacket wasps are small, aggressive predators that live in large colonies and like to bite the heads off of bees for fun. They also seem to really like Mountain Dew, so they are the scourge of southern parks. Their nests are typically underground, with a couple of entrance holes about 2 cm (~3/4 in.) across.
I have played yellowjackets and lawn mower before, so I reacted pretty quickly* and only got one sting. Unfortunately, the little bitch got me right in the back of my knee. How do they know? Except for maybe my eyelids and personals, I can't think of a more tender spot.
I consider myself somewhat of a nature lover, and I value the diversity of life, even in the suburbs. We never spray insecticide around the house, and I don't use chemicals on the lawn, if I can avoid it. Heck, we even humanely trap itinerant mice and haul them off to the woods, where they can be eaten by snakes and owls as God intended. But my ancestors didn't claw their way to the top of the food chain for me to have to avoid parts of my yard. And I don't negotiate with terrorists. So poison ivy gets the Roundup treatment when it pops up, and I keep a can or two of Wasp and Hornet spray handy for occasions like this one.
I stripped to the waist, painted myself blue, and staged a series of lightning raids, wielding my Black Flag like a flamethrower, eventually obscuring the entrance to the nest completely with insecticide foam.** Little wasps were dropping like, um, flies. Oh, the horror! We're a frightening species when the blood lust is upon us, and especially dangerous when injured, I hear. Or is it cornered? Maybe that's tigers.
This morning I went back to dig up the nest, eliminating any survivors. The last thing I need is witnesses. Also, I made the mistake once of thinking a nest was dead after an initial assault, only to have the little buggers having at me again in a few days. Much to my surprise (and relief), it looks like an armadillo beat me to the punch. I hope the little guy didn't get too much of a buzz from the spray. Then again, armadillos aren't my favorite critters, either. They carry leprosy, and dig big holes in the yard.

Fortunately, I'm not allergic. But I guess I had never been stung in a major joint before. After about two hours, my entire knee stiffened up, and it got very difficult to straighten my leg. Also, the sting burned like a lit cigar. It's a little better today, but the soreness helps me justify my killing spree yesterday. Still, if the Hindus are right about this reincarnation thing, I'm going to be in a world of hurt.
