Yellowjacket stings have caused fatalities. Our youngest son happened across a nest in the ground in our north Georgia backyrard woods when he was 5 or 6; they swarmed all over him, stinging him over 20 times. He didn't know which way to run, just screamed and jumped around. I darted in and grabbed him and ran away, getting 6 or 7 stings in the process. After that he became allergic and reacts badly to even a single sting. Now, as an adult, he keeps an epi-pen handy anytime he is working or playing outdoors. My Grandfather was a beekeeper, and my Dad and I had a couple of hives when I was growing up. I like bees (and honey!); but Yellowjackets are a menance!
