For anyone that is trying to bring up mid-summer NUC's, wasps are a pain.
I used to have a live and let live policy. However, once they start slaughtering Queen mating NUC's, and small NUC colony's en-mass, the love of the stripy blighters is soon lost.
I would be interested in knowing the demographics of the wasp lovers - haters in terms of length of time beekeeping, and colony's kept.
Apparently, there are 1000 wasps nest per square mile. Last year, they found their way into my van. They struggled to get out and over the course of a few weeks thousands died. I felt quite awful about it, despite them destroying NUC's.
In 2013, wasps were epidemic on the farm and often couldn't let the children outside to play. They were everywhere.
If they are a hazard remove them, unless you know of a wasp loving beekeeper willing to take them away and rehome them in their back yard. (not sure how many pro-wasp people here would be willing to do this! )...
