Any of ya'll ever been stung by one of those great big Japanese hornets? (Or that's what we call them).
My wife called and said one stung her on the shoulder and said it was way worse than any sting she ever had before. I asked her if she felt like she might be having an allergic reaction and she said she didn't think so but the pain was very bad all the way up to her neck.
I see those things around the house a lot but have never been stung by one.
Giant hornet update (not that anybody cares):
I found where the nest is and it couldn't be in a harder place to irradicate. It appears to be in a small attic section of an add-on room with no access without taking off either the roof or the ceiling (which ain't happening).
There are hundreds of them coming and going through a small opening between the roof and the wall. Tried spraying some wasp and hornet killer up through the crack but didn't do much good. Only pissed them off and they were swarming all around me and I had to sound retreat.
BTW that wasp and hornet spray doesn't seem to instantly kill those things like it does normal hornets.
Read some articles on their stings and it seems they are nasty.
