Re: Treatment-Free Beekeeping without Small Cell
This is not a conundrum at all, just a sign that the bees have natural tolerance mechanisms. As for weavers being a successful commercial treatment free operation, I have to point out that they are not migratory. My defining point of high tolerance is for a colony to be able to survive repeated moves say 3 to 5 times in a year. Exposure to other migratory operations that treat seems to be a deciding factor in survival for mite tolerant lines.
