Hello Everyone, Can you believe almost a month has gone by since my last update? Counted natural mite fall which averaged less than 1 mite/week/hive over the last 30 days. The maximum dropped in any hive was 3 mites/week and the minimum was zero mites. I decided to dust the hives with powdered sugar and count the resulting mite fall as I had done at this time last year. The average mite drop after dusting was 1.6 mites/hive! The maximum was 6 mites from my Harbo hive. The minimum was zero mites from the same hive that had zero natural mite fall. This hive is my most populous hive with 4 deep boxes of bees and brood. The rest of the hives have about 3 deeps with bees and brood. Still, no sign of uncapped purpled eyed pupa. A few pupa have been uncapped on a few frames at an earlier stage but no signs of the extensive cleansing activities that occurred last year. Best Wishes Dennis
