“Their saving grace is, they’re not usually aggressive toward humans and they eat wasps.”
OH...meant to add that when the Europeans build a nest nearby...and you know when they have because we see them constantly, we have like zero wasp nests on the eves because yeah, they hunt them!
This is what we have, they *are* Japanese Hornets, the Japanese make videos of them fighting other nasty buggers, for instance a scorpion:
These hornets are over 2” long, sort of tiger striped, have a 1/4” stinger, very hard shelled. They attack wasp nests, kill and eat the wasps then eat the larvae in the nest. They’re not particularly aggressive towards people unless provoked, and you really don’t want to provoke them.
