Any right thinking human who picked up a can of pop to take a drink in the summer months and has been nailed by one, hates them, Chris.
I went up to do battle in the attic with wasps a few years back in similar circumstances. I had the jumbo can of Raid Hornet and Wasp gunk, canvas gloves, safety goggles, coveralls, more clothes under those, a hoody pulled tight, and a cheap painters double air filter. Let me tell you, I was wishing I hadn't gave away Grandpa's bee-keeping outfit when the heat from the attic hit me.
I didn't need the clothes, but a better air filter would have been have been nice. They were by one of the side vents, about 8 feet away from the attic entrance. I gave them several blasts and that was that. I must have got the queen, as when I checked a couple of days later there were a lot of dead wasps and the rest were gone. It was so hot in the attic I think they were more concerned about keeping the queen cool than worrying about a giant beetle looking thing that had popped it's head up through the floor? I was woozy for most of the rest of the day from those Raid fumes. Good ol' Raid, extra bug killing power and a geeky buzz in every can.
I rented a house once where the enclosed space over the porch got full of hornets one summer. The buzzing was so loud some nights it was hard to sleep. I had a good landlord. I called him about a week into it. He called the exterminator, and the job was done the next day. I think bug killers name was Shackleford?
It's odd the way various insect stings effect different people. Wasp and yellow jacket stings hurt, but they don't cause me to have much of reaction, just a red bump that hurts. I step on a bumblebee and my foot will swell to the size of a hippo's. Sand hornets are in a league of their own. We've got scorpions, but they're tiny. They look like a slightly oversized, off colored silverfish and are said to pack a punch between a sweat bee and your average horsefly, but the sting swells a bit. They live mostly in abandoned sheds, old houses, and unfinished dry basements.
Brown recluse spiders cause a lot of damage here due to the nature of their venom. It eats away at the flesh and muscle around the wound. Nasty little things, and they're everywhere. They can occasionally kill depending on the age and health of the victim. You never know they're there until you disturb one and then it's too late.
Just be glad the Eurasian hornet has never made the trans-oceanic trip and gone native. Those things can kill children, the ill, and the elderly with a single sting.
