Got swarmed with wasps

We decided to check out a different camp site over the weekend and got swarmed with wasps when the sun was at its warmest.

Luckily the next day and during packup it was over cast and cool so they couldn't fly, but we spent like an hour shaking wasps out from all the poles of the canopy. We easily stomped to death over a hundred wasps that fell out, I've never seen anything like it
