I found a yellow jacket nest the hard way this afternoon. Luckily, they only got me about 7 times and only 2 of those were full force stings.
Because of my experience, I searched for "yellow" and found this thread. IF that picture is real, that dude is one crazy fellow if he is knowingly standing so close to such a nest from Hades. One fallen branch or pine cone and he might not be with us.
Same with me, I found a yelowjacket nest in the eve jsut as I was putting on the very last panel of insulation on the veranda roof. I couldn't get down the ladder fast enough and fell down the last few rungs, scraped up my kneee and hand but nothing major. Usually the Yellow Jacets around here jsut dive bomb you and give you a quick stick, but this time I got two really deep stings. Put ice on it right away but the next day I had swelling. Took an Allegra the second night after the sting and woke up just fine.
7 stings! ouch! What were you doing?
