I have just undertaken a varroa count on Hive Two. 40 mites dropped over 8 days. The Varroa Mite calculator, calculates the following:
- Average Daily Mite Fall = 5.0 varroa mites
- Estimated number of adult varroa mites in the colony = 2,000
- Treatment is recommended as soon as practically possible
What makes this unbelievable is that the varroa count on 24th August 2013 came out as a low 290 mites in the colony and even after that I applied Apiguard for two weeks.
It looks like I will have to apply Oxalic Acid next weekend – let’s hope it’s mild.
