Meh, poison ivy is just another vine to me. I'm not allergic at all to that nor really to wasp/hornets. But I won't say wasps/hornets are just another bug, especially the ones that build paper nests. Dirt daubers are just fine by me, because they're not aggressive and don't sting. But the aggressive wasps/hornets do hurt when they sting, and the pheromones in the sting put me in a rage, particularly yellow jackets. I find every nest I can after getting stung and go on a murderous rampage that night. I wait til night so I make sure I get 'em all. They shoulda taught their relative better manners. Next morning, it's business as usual and continuation of cohabitation as long as they respect the property owner(me).
I'll tolerate them for controlling spiders, but when they buzz me or light on me, I start doing
judy chops and ninjy kicks. Most of the time, if it's a singular red or mahogany wasp, or black/white hornet, I just get 'em with a hat trick (use my ball cap to knock 'em down and then step on 'em) Not afraid of 'em, just don't like sneak attacks. If I see them first, I leave 'em alone and try not to disturb them unless the nest is too close to inhabited or work areas.
Wasps eat a LOT of spiders. If you don't have facial hair, you just cannot appreciate that sudden trigger of a redneck ninja kung fu response when a pot licker spider web wraps around your face. If there's one thing that will make me shave, it's getting two spider webs in the face in one day. It's probably pretty amusing to watch me from a distance if I get stung or if I get a web on my face. Certainly, you need to be out of earshot if you don't like bad language, which spews forth like an erupting volcano when there's the inadvertent encounter with arachnids to the face or puncture wounds from hornets.
