Well ..... here’s the reply
Hi, I'm the one reading the comments. You can address me directly. 1. I treated OAV 3 times at 7 day intervals. Third treatment had virtually no mite drop on the boards so everything seemed OK by late October. Yes, it's late, but there were no mites dropping after 3 rounds. 2. I did splits in May like I had done the past 3 years. I could not have predicted there would be zero spring, summer, or fall flow last year. There was just NO nectar all year. Once I realized how dry the hives were, I had to feed. Combining might have helped. but even my largest, strongest hives did not make it through this winter. 3. NO. The burlap is for wicking moisture. There is 2" of foam on the sides and top surrounding the entire box. The Vivaldi board area stays warm under the insulation and creates a warm layer of air over the cluster. This system has gotten 85-100% of my colonies through the past 4 winters. 4. There is no robbing because they are the only bees alive in the area. Also, those frames are hardly touched since I put them there. I suspect they are completely full of stores because they also have 13 dead colonies in the bee yard to rob. 5. What would you suggest I feed 14 starving colonies? 2019 was a year of magical nectar foraging. There was a near continuous flow of nectar in the hives and I didn't need to feed at all. The area CAN support this many colonies. However, when it DOES NOT RAIN for 4 months during the only available time these bees have to find food, the flowers are not throwing off nectar. There were extreme circumstances I had no control over. This was not a dry couple of weeks. There was NO FLOW all season. The bees were struggling. All I could do was feed them syrup and sugar. There are some things that are just out of my control. A nightmarishly dry spring/summer/fall followed by a colder than normal winter was too much. There are a hundred comments on this video with other beekeepers in my region with similar losses. Did I make some mistakes? Sure, but this was a very bad year that would have been a struggle for even the most experienced beekeeper.
