I would love to know more about Red Paper Wasps from you, how to befriend them and how they protect your crops :) How do they know the fried chicken crumbs are from the human and the human is not a threat??
Obligatory reminder that I am Some Rando on the internet, not an entomologist and you should exercise caution trying out ANY Advice you fine online.
Wasps in general are great at protecting crops because wasps are carnivores: bees get their protein from pollen, most wasps get it from the flesh of smaller insects, worms, and and foodscraps humans leave out. Most paper wasp nests are founded by a single queen who got pregnant in the fall, buried herself over winter, and woke up in spring to give birth to a squadron of grubs, all of which she needs to stuff meat into to they can grow up to be good helpers for the army of wasps she and her daughters are going to produce. The individual gender and generational dynamics of different types of wasps are fascinating and I highly reccomend reading up on them, but the net result is that if you can get a colony of wasps to establish in your yard, you garden will be the FIRST place they go looking for snacks.
The wasps do not know the fried chicken crumbs are from the humans, and may or may not actually possess a sense of social reciprocity, so you have to deploy the fried chicken bits STRATEGICALLY.
I wait until I see the firsts wasp queens coming out of the ground from hibernation, get a bucket of fried chicken, enjoy it, and then leave a handful of cumbs and bones with shreds of meat on them in a less-traversed corner of the yard (off the ground so the dogs don't eat them and give me vet bills from hell). I only do this for like, a week, maximum, because I don't want to be feeding the wasps. I want to make the emerging queens think that my yard is a good place to build a nest, and then cut her off so she starts eating the aphids.
During this time, I rigorously patrol the yard (walk around the house when i go to get the mail) and knock down nests in unsuitable locations- anywhere high-traffic (Like right next to the garage door or inside the mailbox) or structurally unstable (On a bare and skinny elderberry branch that would snap as soon as their was any real weight on it). Nests that are in safe-for-humans-and-dogs locations are allowed to stay.
The only non-nest-establishment time I deploy fried chicken is when I'm going to be doing something in the yard that the wasps will be interested in but not helpful during, like painting or dyeing projects. Then I will set out a broken-up piece of fried chicken on the far side of the yard from where I will be working at least 20 minutes before I start, and that holds their attention nicely. This also works for picnics- put a piece of meat on a far table BEFORE you start setting up and that will hold the attention of any wasps in the area while you eat. I go out and get any leftovers after sunset when they've gone to bed.
The wasps DO know the humans are not a threat by the humans not acting like threats. If you have wasps established in an area where they are On Alert and you don't want to/can't remove the nest, this is what you do:
- walk by normally as though the wasps aren't there. Wasps read human body language remarkably well and ignoring them signals that you are not about to rip the nest open.
- If a wasp flies up into your immediate proximity, hold still or keep walking as you were. DO NOT jerk away suddenly or try to swat it. The wasp is probably just confused by the patterns of your graphic t-shirt or the smell of your deodorant. Give it like two seconds to eyeball you and it will leave, as well as relay the fact that you're not going to be a problem to the other wasps.
- If a wasp lands on you, wait for it to leave or use the paper-and-cup method to remove it from your person. Sometimes they want to hang out, and once you've learned to not panic about Wasps, having one hang out on your sleeve or hat is NBD.
-If you accidentally squish a wasp, Calmly leave the area immediately, go wash your hands and anything that touched the dead wasp, and wait at least 20 minutes before returning to the location of the dead wasp. The body of the dying wasp produces a pungent "ALERT! SOME FUCKER HAS KILLED ME!!" chemicals and that puts all wasps in the area n high alert. Running makes them think you're the aggressor and they'll defend the nest with a strong offense. walking calmly away, washing he alarm chemicals off and waiting for things to calm down will prevent you from getting on your local nest's shit list.
-Try to avoid eating bananas, wearing anything Banana Scented or using Suave-Brand Shampoo/banana boat sunscreen as those scents are extremely similar to the "ALERT! THERE'S A HOMICIDAL MANIAC!!" chemicals.
And that's it! Prevent wasps from establishing nests in risky areas, stay calm when approached and try to not smell like a corpse and you will get along great!
