Re: Northeast warmup - hive check
I hope your hive can hang in there, that looks like a huge die off. Using MAQs and OA this time of year will kill the mites but the virus's that they were carrying have already damaged your bees, that's not to say your bees won't make it but they have a tough fight ahead of them. It is always best to treat the hives in September to kill most of the mites and the bees will have the opportunity to raise at least 2 cycles of healthy brood before winter sets in.
I wish you the best.
