[QUOTE="John B, post: 12308, member: 207"] Round here hives can and are regularly killed by wasps. I had sites where it was not unusual to kill 20 to 30 nests within 100 m of the apiary (vespecs was a game changer) and all I have seen literally hundreds of hives killed by them in one particularly bad season. You can reduce deaths by using entrance reduces and tracking and killing nests as well as breeding for wasp resistance but it's still easy to get caught out with no visible wasps when shutting down the hives in autumn and dead hives in the spring especially in mountain areas where wasps are less common but seem to do more damage . Absolutely they pick on the weakest hives first but given enough of them and enough time they will kill almost everything 15/16 is the worst I have ever seen and the only survivor was headed by a crossbred Queen with a lot of the local survivor genes.
