A word of advice. The product Sevin is highly toxic
too. If you read what you should be wearing (PPE) you might change your mind.
Chemical gloves, goggles, and a OSHA respirator (since you are inside of a
greenhouse) are just some of the gear you will need to wear.
I know it is a tough problem but be sure to protect

And for the wasp nest - best I can figure out is to spray the nest with
either Rotenone (organic) or Sevin (not organic). Any treatment must be done
at night, as the wasps will be in the nest and more docile.
If you have had a bad reaction to the stings, get someone else to do the work!
Shovel soil on the nest only after all activity has ceased. And a word about
the chemicals ; Rotenone, although considered organic, is one of the most
toxic chemicals out there - kidney and liver damage, highly toxic to fish,
very broad spectrum (though a fairly short residual)- please be very careful
and read all directions if you choose to go that route. Sevin is also pretty
dangerous (a nerve toxin and very water-soluble), but I think we forget that
the organic stuff is also lethal. I would ordinarily not suggest spraying, but
clearly you have a problem and that seems to be the best (only) way I've found
