Hive F still shedding lots of Varroa

Submitted by will on Thu, 11/05/2017 - 05:53

I looked at Hive F's removable floor again on Tuesday 9th May. I counted 24 Varroa mites which had fallen out of the colony. That's 8 per day. Will they survive?

UPDATE: I visited the hive on 12th May after dark. There were another 32 mites. I've counted 88 mites in 7.5 days, an average of about 12 per day. That's very high. This colony has been untreated for a couple of years but it was from a bought queen before that. I don't think much of its' ability to manage Varroa.

Making space for Drones part 2

I've made a small adjustment to the Commercial frames which should work just as well in an National deep (brood) box.

I took an old National brood frame and removed the two bars which are set at the bottom. These are 6mm x 8mm x 360mm. I cut them into 4 equal 90mm lengths. I glued and nailed these to the sides of the top bars. I made these adjustments to 3 of the frames.

The result is that the frames are spaced at 12mm apart instead of 8mm. The Commercial box fits 11 instead of 12 frames.

Queen exclusion in Hive D

Submitted by will on Wed, 10/05/2017 - 19:55

I moved the queen excluded in Hive D yesterday. It is now between the brood box and the supers, where it ought to be.

I moved the frames from the super to a fresh super box, shaking each a little in the hope of moving the queen down. She leaves behind plenty of brood on the super frames, including Drone.

Drone can't fit between the bars of a queen excluder so I'm going to have to release them at some point. I'm not sure how to do that...
