Don't forget about these friendly fellows:

Asian murder hornets.

Yes they are over 2 inches or 5cm long, they are huge, and are a menace. Unfortunately due to climate change they've found a foothold in Western Europe and are pretty common these days. The advice is to not kill them, but instead try to figure out where the nest is by following them. That way they can be cleared properly instead of just killing the one. Plus getting in a fight with them is a good way to get hurt, so don't do that.
