I tried to post in the disease and pests section but kept getting logged out? I'm a fairly new beekeeper and have never worried about varroa mites. I did an inspection today on one of my hives and noticed bees with partial wings and brood that was dead in the cells. Checked for mites and had 36 in 300 bees, 12%. I have researched this but wanted your all's opinion of what to do?
