Warm enough to test the level of varroa in my colonies by dusting the seams with icing sugar, trays in underneath. First time I've taken the crown boards off and lovely to see all is busy, no mould, and in the case of the largest colony dripping honey from wild comb on the underside of the crown board.
I did a different thing today: I placed a QE over the brood box prior to doing the dusting with icing sugar, to keep the majority of bees in place. Only a tiny number attempted to climb through. Neat.
Another new thing: I knew that one of the colonies I was due to dust is mega huge on double brood, both boxes full of bees. So I came to the task with spare stand, base, crownboard and roof. I split the colony in something like artificial swarm style - just for these 24 hours! - and dusted the two boxes separately, each one with a tray in. Tomorrow I will put them back together of course.
