 Treating colonies with a battery powered oxalic acid vaporizer and insert to cover the entrance and openings of the screened bottom board. Photo by Eric Malcolm, November 5, 2025. | Time in the Yard: 2 hours 22 minutes Avg Time per Colony: 5.26 minutes Total Colonies: 27 Avg Temp: 50.6° Total Precipitation: 0.27” Note: To legally apply the new dosage for Api-Bioxal, beekeepers are required to have the product with the new label affixed by the manufacturing facility. |
Actions:
Confirmed colonies were alive and applied Oxalic Acid Vaporization (OAV) treatments. Took records of hive boxes that needed to be replaced prior to winter.
Observations:
Our newly purchased Api-Bioxal application instructions include updated dosage of 4g per brood chamber. Some colonies had little or no entrance activity while others were very active. All except one colony was of a gentle temperament during treatment.
Reflections:
Weather is slowly getting cooler and we’re planning to get one more round of 2:1 on before switching to feeding fondant.
Things in bloom:
Common Chrysanthemum, Tatarian Aster, Elegant Zinnia, Yellow Cosmos, Common Yarrow, Japanese Camellia, Sasanqua Camellia
