It's hard for me to even conceive of encountering something this immensely dangerous in the woods...
Simkins was staring down a yellow jacket colony about the size of a Smart car that posed a lethal danger to hunters and lumberjacks on a thousand-acre timber lot in Central Florida. It took him two days to vanquish the three-to-five-year-old colony, which housed a thousand queen wasps and a million “daughters.”I thought the swarming clue happened when you crushed one of them; didn't know they could regurgitate on you to mark you. You learn something every day.
“The alarm pheromone was so strong it made my eyes water and my nose run. When they land on you, they regurgitate so the others can find you.”
Hat tip to Kev at Nothing to do with Arbroath.
