When I had Foley's Russian Bees, colonies were in decline at this time of the year. I spent most of my time cleaning dead outs! Now after breeding my own queens, I have more colonies than I've ever had before! As long as Formic Pro formic acid continues to kill mites, I'll be able to increase every year! Winter is spent monitoring colony strength. I have some new colonies outside that will be brought inside during sub zero temps. I know I can do better than the 41% loss that the commercial beekeepers had last winter! My losses last winter were ZERO! I did lose a Foley queen, but not the colony. Therefore that one doesn't count. I CAN"T DO MUCH ABOUT THE POOR QUALITY OF FOLEY"S RUSSIAN BEES! So heed my warning, DON"T BUY FOLEY"S RUSSIAN BEES!
