Mite wash came back at 9 per 300 — treat now or wait for the flow to end?
Did an alcohol wash this morning on my strongest hive and counted 9 mites. Main nectar flow has maybe 2 weeks left. Do I pull supers and treat with formic now, or risk the wait?
Temps are 22–28°C all next week. Bees look strong, brood pattern is solid. I have Formic Pro and Apivar on hand.

At 9/300 you're over threshold — don't gamble. Formic Pro works with supers on if temps stay under 29°C. Two weeks of brood damage isn't worth the honey.

Watch the temps closely though — formic over 30°C will cook the queen. If you're touching 29 the day of application, switch to one of the cooler protocols. With Apivar you'd need supers off anyway.

Provence, eight years, sixteen hives. A neighbour clearing branches found a nest the size of a beach ball high in a plane tree at the edge of the village, and it's unmist…

Reading the tray debris in October — what do wax flakes, chewed cappings and pollen crumbs tell me about the cluster?
Vermont, second year. After the mess I made of not noticing a dying colony last month I've put clean trays under all three remaining hives, partly for mite counts and par…

Oxalic dribble or a vaporiser for four hives in Kent — which would you buy, and what safety kit do I actually need?
Kent, third year, five colonies after the unite. My winter treatment has always been a dribble because that's what my mentor lent me, and a few people at the association …

No broodless window in southern Spain — is caging the queen to get a clean varroa treatment worth the risk?
Andalusia, ten years, 22 colonies. The northern threads about timing a treatment for the broodless period are lovely to read and completely inapplicable here. My colonies…

Late-October robbing at 24°C in Georgia — my entrance setup and how I spot the hive that's being stripped
Twenty-two years in middle Georgia, 40-odd colonies. October here isn't a wind-down, it's a knife fight. Days still hitting 24°C, nothing much coming in, and every colony…
