Too much Acid?
The mite treatment for my second bee colony has finished a while ago. Check
here for details on how the mite treatment works (
More Bees and Mite
The excerpt from my bee diary reads like this:
2014-10-12: Removed empty Liebig dispenser from colony 2 and also removed the
varroa drawer. Took away the top body as well. Checking an area of 5 by 5 cm
on the varroa drawer revealed about 123 varroa mites. Extrapolated to the
whole seemingly used surface this means a total of approx. 1180 mites and a
daily drop rate of 90.
This looks pretty much like a success. During the treatment there was however
one very hot day right after it had started. A very hot day means that the
formic acid from the Liebig dispenser evaporates quickly. Maybe too quickly
which would lead to too high a concentration inside the hive air. I also noted
that the bees seemed quite stressed out. Maybe the queen has been killed by a
too high concentration of formic acid. But then there was very little I could
do. Stopping the treatment would have reduced the chance for this already
small colony to survive the winter.
Taking Another Peek Inside
After the treatment was finished I got nervous and simply wanted to know
whether the queen had been killed. Even though at this time of the year there
was very little I could have done about that. So I just had to search for
This second colony is however in general a bit more aggressive. Add to that
the stress of the treatment and the lower temperature I put on my gear at this
time. Usually I do not need it but after a short failed attempt I just wanted
to make sure I do not get stung in the face.
So here we go. A look in the second colony.
This is the only frame which still has brood on it in all stages. That should
be OK. The other frames are filled up with food. You can already see
if you look closely.
A closeup of the brood. I just love to see the bees dive in head first in the
cells when they are feeding the larvae.
Here she is in all her glory.

I also could not resist to check on colony 1. There is a lot of food and also
still some brood in all stages. Have a look:
And to conclude we now have a lucky and a bit indecent snapshot of one of my
workers on a nearby leaf. She looked
Seems like someone had too much of that sugary water :).
