It's August-- the time for us beeks to really make sure that those varroa numbers are down. And it's still warm enough for treatments like sugar drenches with Honey Bee Healthy.
I have a hive whose entire worker population seems to hang out on the front porch a few hours before sunset. I was thinking that this would be a much more efficient way of spraying my bees down with sugar water with essential oils to encourage hygienic behavours. Much more efficient than than tearing this queenless, ornery hive to pieces, frame by frame, and spraying them down.

Can you think of any problems with this? I'd suit up and spray them down really good. Our temps have been wavering at night, down to 63, but I still can't imagine that would chill adult bees. Worse comes to worse they could withdraw into the hive, right?
