Why Do They Keep Building It?

I had to remove burr combs for the first time this year.  I felt so guilty for doing it since there were so many capped cells and open cells with larvae and eggs in them.  I have wasted a few hundred would-be worker bees.

Two weeks have passed since I first spotted the burr comb, by looking up from under the hive, but I couldn’t do anything about it.  It had been either too windy or raining, and on the one good weather day I was at work.  The next thing I knew the burr comb almost reached the screen on the bottom board.  I opened the hive for inspection and lifted up one of the foundation racks, the comb broke off.  Not much I could do, really.

Aside from partially filled cells on the foundation, the bees have built the burr comb right under four of the foundation racks.  It was as though they used the bottom of each foundation as the anchor bar for building a comb in the same way as a top bar hive.  They were perfectly shaped combs.  I know that bees will try to fill up any space between the foundations if they aren’t spaced perfectly evenly.  But under the foundations?  I thought perhaps because I used a deeper hive body, but the hives are identical and it’s the only hive that’s doing it.  The other hives are behaving normally.  Maybe these bees were traumatized?  This group of bees did have an unhappy and unusual, albeit short, experience I will alliterate in another post.

Ten days after I did the last inspection, the bees started to build the burr comb under the foundation again.  Hopefully the weather permits me to open the hive and scrape it off before the queen lays eggs in them.  I’m still trying to figure out why this hive keeps building burr combs. I’ve changed the hive body from deep to a medium one as an experiment and it seems to be working so far.  They’ve stopped building the burr comb but they are bearding outside in the morning and afternoon whenever it’s hot and humid.  I hope they’re not planning to swarm so soon.
