I’ve eradicated 2 nests of european wasps here in Australia by dumping a pretty strong solution of dish soap and water down the nest.
Carefully, at night, with red light just to be sure.
They are the most aggressive pests I’ve ever had the misfortune to run across, if you kill one, you get attacked instantly, and they will chase you, if it was a large active nest, I’d be very cautious.
