from what i have experienced this is going to be a very good tool in the fight against varoa
the first couple days there is a lot of bearding and this clears up-there was dead bees on the
ground -there was no injury or mortality to queens--except in colonies under five frames of bees
i had three colonies less than five frames of bees-which i gave full dose-two got fried and one
needed major help to get up and running again-all in all the bees rebounded back to point that they
are swarming if not managed -the cost was $140 per 40 treatments-so $3.50 per hive-only available to me at that time in
40 treatment size pails-but it is suppose to come around in ten packs-now i need to monitor and see how long it lasts
but i will say this it kills mites very effectively -i will use it again - 8-) RDY-B
