@alavi @thibaultamartin aren't hornets actually usefull? I mean if not really inside the house, but around.
@alavi @thibaultamartin didn't search long, but here seems to be an explanation in english quite ok:

So to keep wasps and other stuff away, its actually good to have them. Except when your alergic of course, or when theyr habitat interferes directly with humans. Which would give them a reason to attack.
@petrisch @thibaultamartin
I don't have enough knowledge to say something actually valid about this, but as far as I remember the obliterate bees and just sting people for no reason.
