As usual, our beekeeping activities have been at the mercy of weather and life’s other demands so the exact dates of the various events we now report are a bit vague. We should have taken better notes but see “life’s other demands”, mentioned just now. Anyway, after our last sugar roll we had applied Mite Away Quick Strips to the hives. When we finally returned to remove the strips, we decided to check the efficacy with another sugar roll. We began with Dorcas and to our horror discovered a count of 9 mites per hundred bees! We did not proceed to the other hives but hastened to consult Dr. Meghan Milbrath, who must be rather accustomed to our panics by now.
After determining that we had seen no signs of deformed wings or other symptoms of varroa-carried viruses or any indications of ill health but that we had observed there was very little brood, she opined that the mite count may have jumped because mites that had been hiding from treatment within the brood were now phoretic. She also said that she had seen nearly treble our mite counts in untreated hives this time of year and suggested we could treat with oxalic acid using Randy Oliver’s specifications for a medium strength syrup as she does at the Sand Hill.
Somewhat reassured we mixed a batch of such syrup for three hives and went to apply with our trusty syringe, once more beginning with Dorcas. We had planned to start from the follower and spread all the bars apart, then squirt the recommended five milliliters(5 ml) along each seam, deliberately wetting the bees. Unfortunately, we found that Dorcas had at some time suffered a comb collapse and we did not wish to deal with trying to fix things, spilling honey, and asking to be stung. We expected to already make ourselves unwelcome with the treatment.
We merely pried bars apart a wee bit, cutting and undoing much propolyzing, without shaking the hive or breaking free any possible attachments. Then we wielded the syringe along each crack and pushed the bars back together. To our surprise the bees did not seem to mind being dribbled with the syrup at all. At least they expended their energies in cleaning each other rather than stinging us.
Repeat for Clarissa and Beatrix, both of whom were also mellow and unbothered by our ministrations, without any more sad discoveries of fallen comb. And so we can do no more except wrap the hives for winter once this latest warm spell ends and worry and hope. We are so weary of deadouts come springtime.
