Michael,
I sort of figured that was the default position, but I want to help my hives as much as I can, without resorting to "heroic" measures. I mean,healthy, happy hives, with minimum interference, right?
It's only a matter of time for the arrival of varroa here, both sides of politics have spent years weakening our quarantine process, to "save money" - I think the defining fault or Achilles heel of democracy seems to be that long term planning is a up until the next budget/election cycle (and short term planning is covering up what happened last week). Next thing, we will have rabies, just about everything else, from small hive beetle to Asian Bees, to papaya fly, has come in since the "reforms" of Quarantine started big time in the nineties.
