I really like the orkin wasp foaming spray.... our local Home Depot stocks it.
It goes where you want it to go. Foams up sort of like shaving “cream” once you hit your target. Any wasps that come out, get coated in the foam and die pretty quickly. And has a good 15-20’ reach from the can. We have a lot of nests in the eves of our house, wood shed, barn, and coops. The spray also works well for nests in trees, and may need a second application for ground hives but is still by far the best I’ve found.
The traps do nothing this time of the year IMO.
And my pools for the ducks, and water founts for the turkeys, are completely innundated rn. Idk where you live- but this is a horrible year for wasps and hornets in the PNW
If anyone has any thoughts on how to discourage the little pests from coming to the open waterers that the turkeys and ducks need, please speak up!
I’m so frustrated!
The birds don’t seem to be particularly bothered yet, but I also know that yellowjackets and bald faced hornets (our most frequent “visitors”) become more aggressive in the fall as the nights get more cool

Also. To the OP
I’m not clear on where exactly your nests are....
if they are outside the coop- I suggest the spray, and then hose the area down well before letting them out in the morning.
if they are inside the coop area....I’d wait for a cool night,leave the birds in the run later than normal (and ignore their protests!), hit the wasps w a solid stream from a sprayer nozzle on a hose.... with long pants, boots, and a long sleeve short on, and kill the stunned a**holes w a boot or the wide side of a broom.
Or. Option 2 if the nests are in the coop-
Put your crew out early in the am.
Spray the nests with your birds outside, let the bees fall down and the foam stop dripping, and then scrape out the coop well (to clean up dead wasps and and residual spray), and hose it out/ close them out for the day.
Add heavy bedding before bed time just to be safe.
At least. That’s what I would do...
Horrible little angry things.... I’m always happy to dispatch them
