I did a sugar shake test on my hives yesterday and one of them had a varroa count of 10, but the sample probably had around 400 bees in it. That seems a bit high for this time of the year, but 'Practical beekeeping in NZ' says treat if there are 40 or more, and 'Control of Varroa' has a threshold of 65 mites. What do other people use as a threshold? I could treat now as this hive was split and is rebuilding at the moment, but am unsure if it is necessary.
