Wasps don’t swarm like that. They’ll only form a cloud of death if you bung up the door to their house while they’re out.
Despite their reputation, wasps are actually really useful as they munch on all sorts of decaying junk. Their nests are amazing as well.
Still, didn’t stop me getting someone round to be perform a waspectomy on our house this morning. Apparently they’re nearing super early this year, the guy said his first removal was at the start of April.
All of which is actually irrelevant, due to the fact what you’ve got there is bees, and they’re lovely and not to be killed.
