I have been beekeeping for awhile now. Over the years I have purchased queens from breeder all over the USA. I have a good mix of bees Italian, Russian, Cordovan and Carniolan. I have good bees they always produce honey and I loose very few to no hives a year. I have sold nucs to a few local beekeepers and given them queens. Everyone seems to like them, but I have mites. My bees seem to live with them, I have never treated them for mites and I rarely loose a hive. My concern is that a beekeeper may infest there yard with mites from my nucs. I was wanting to sell about 30 to 40 nucs this spring and queens. I have never treated my nucs but would you treat them before you sale them?
