For people that don’t know, regular wasps always leave in the face of danger to the nest. If you have the typical small nest, the easiest thing you can do is hit it fast with a broom or similar. They will all disappear in seconds.

I’ve seen my dad do it a lot of times with his bare hands, never got stung. But if you pass by the nest enough times, you’ll be.

Another good solution is fire. A blow torch with a wide flame, burns their wings (if it doesn’t outright kill them) and also their nest, which is more or less made of paper.
