I'm alway leary of Yellow Jackets, of course if they sting you, you know it. I have excessive (by most sting standards) swelling from them, no anaphalaxis at all, but as Pink Floyd says so well "my hands felt just like two balloons" which was an understatement.
Getting sprayed though (if it was something like that) is something I never dealt with, lucky me I guess. Been through Neurological Lymes (right to the spinal cord and to the brain version - rare but most often physically and mentally debillatating) I got lucky and only have some short term memory and often I use the wrong NOUN when describing stuff - literally, I'll look at a toaster and have to think of what it is called. Luckily, that is as bad as I got, many people have paralasys, stroke like symptoms, horrible ticks and twitches. Regular lymes is bad and untreated can be horrific, but Neurological (use to be called Lymes Mennengitis) can be real killer.
So those insects we deal with every time we wonder in the yard or woods can be deadly or crippling. I've read yellowjack venom (ounce for ounce) is as strong as rattlesnake, the only worse common creature is the brown recluse spider which is a flesh eater bacteria - I've seen videos of treated and untreated people after being bitten by them and it is sickening how fast flesh can die away from their bite.
Honey as a topical against itch is a good one, I've had some severe poison Ivy before, from my hand to my shoulder and NOTHING feels better than scratching poison ivy (it is in a world of pleasure of its very own) but of course nothing makes it spread faster. Getting honey on there to kill surface air from allowing bacteria to spread stops the crawling feeling and does help the spread. I was told once by my mentor that if you add a good squirt of ORA-GEL cream to the honey, it kills the itch all together, numbs the area and the honey gets a much better heal time before you start itching again.
Best wishes to everyone in the yard, it is so strange that something so small that you can't see it has greater distructive power that a run-away truck. At least the truck, you MIGHT be able to dive out of the way of, you don't even know when the garden critters can change your life, and often it is our pets that bring them in, you don't even have to leave the couch - ugh.
