I am not too far from you I presume. I Have never imprted bees nor have I bought into The native bee yet. All my bees are caught from swarms or decendants of the origonla single nuc I bought from Darren, who is a memenr on here. I had issues with a number of aggressive hives a few seasons ago which I managed to get on top of by taking a zero tolerance attitude to aggressive queens. Basically identifying my most agressive colonies and getting rid of the queen at the apropriate time. Any hives with queen cells were split three ways and all but the best queen dispatched. My bees may be all mongrels, but they are my mongrels.
