This particular hive was a small late July caught swarm. I did give it a boost with a couple of frames of brood from the first caught swarm which appear to be Italians. These bees appear to be smaller then the big hive's bees. I am thinking it may be a swarm from a feral colony. So I don't have any history on either hive.
I sugar dusted a few weeks ago as I did see a few mites in both hives. I would like that number to stay at "a few".
Make me wonder as well if they might do a number on the SHB larva that drop to the ground to pupate. Fire ants are not my favorite people, but maybe they have their purpose.
My best hives came from feral bees and they stay pretty much mite free. They had to figure out on there own how to survive. They probably superseded the queens and selected one with the right genetics.
Most larva make great morsels. I'm sure the ants love them.
I do not sugar dust my hives. Tried it in the beginning when my hives had lots of mites. But it did not help my bees.
