This is now the second nest wasps have built in my greenhouse after I removed the first one. I don’t want to spray chemical wasp repellent and risk it getting on my vegetable plants. Any advice?
They say if you hang paper bags then it resembles another nest to bees and they won’t build their nest there

Soapy water and physically remove them

I know many are against using chemicals especially in the green house. I was too until I got stung many times last year. Now as soon as I see a nest I hit it with a good blast of foaming type wasp killer. Put some plastic over your veggies if you go this route.

You can try covering it with DE for pools. Diatomaceous Earth isn’t a chemical and is perfectly safe unless you’re an insect.

it takes months for them to make a nest that big…frfr they dgaf about you, unless you damage that tiny home, yall will never beef.

What everyone has said, plus hang up a fake wasp nest. They’re very territorial, and won’t nest near another nest

If you’re looking for a quick removal either a gas cup for them to trap and they drop in (but it looks like they are on the side of something so probably won’t work) or you can spray with WD40. They won’t be able to fly off and you can smush them with your shoe and then remove and smash/burn the nest. Recommended to do any removals at night when they are not as outwardly aggressive. Then do what everyone else says- put a fake nest somewhere outside the greenhouse. But make sure to actually attach it somehow to the actual greenhouse and not a few feet away as they won’t be deterred from making their own inside it. I bought a 3 pack off Amazon and I never get the aggressive wasps in my shed- every now and then one will fly through but they leave within a few minutes. Another option is to leave it alone, make sure it doesn’t get too large, and get rid of it in the winter when nothing is pollinating anymore. These guys are good pollinators so if you have an amicable relationship with this mini nest then I might leave it!

Just ignore it IMO. If it’s gotten that big without getting aggressive already (assuming you’ve spent time in the greenhouse), then the group is just not particularly aggressive.
We had one build a rather large colony above our garage door. We walked under it constantly. They recognized we weren’t a threat. You could get up within inches and just watch them. They’d turn and stare at you but not do anything else (we were careful not to make fast aggressive moves with our hands).

Dish soap and water will kill them instantly. Drops them out of the air even. Works better than the store bought poison spray. Use a spray bottle or garden sprayer. If they’re not in a place that they would interfere with people’s safety, just leave them alone.

That’s a perfect place for a pitcher plant. They eat their weight in wasps. Mine start hunting about the time the wasps start building nest and making larvae. Great time to get rid of the adults.
