Wasps, I also emptied my wasp trap at my apiary near Wynyard for the 5th time in 2 weeks. They killed a nuc and have tortured my bees this year. I destroyed one wasp nest but there must be several others as I can't empty this fast enough.
Urghh........thats a lot of wasps!!!
I've not seen many at all this year down South??!! Maybe they all flew up North:)
