I still have a lot to learn. Of course I don't want to do anything that will harm by bees. I've read about mites and of a couple of chemical treatments and one natural. My bees are a feral hive that was captured in April. I haven't done any chemical treatments- I rather not- but I do have some APIGUARD and a sticky board to check the hive, but I haven't used either of them. Am I wrong to think that it's too late in the season to use them? Please correct me if I am. I am thinking that my hive must be a strong one if they have survived in the chimney for at least 4 years. I have watched closely and I don't see any mites on their bodies. I have 2 supers. Bottom is full and the 2nd is 80%.
