I have lost the most bees this year than ever before and am trying to determine the cause. The sheltered yards survived better than others. Some tracheal mite losses but many were starved or died with honey nearby. Was it the winter, or was the meds of poor quality? I have not yet seen a pattern of loss that holds for all yards. I treated early with two apistan strips and a patty. Contact me at: Rick Green 8 Hickory Grove Lane Ballston Lake, NY 12019 (518) 384-2539 [log in to unmask]
