"My bees have survived 3 years untreated" — genuinely curious how people weigh this against the drift argument

Not looking for a flame war, genuinely trying to think this through. A guy at our association — decent beekeeper, not a crank — hasn't treated for varroa in three years a…

Yellowjacket trap baits — what actually works without catching your own bees?

Texas, four hives. Yellowjacket pressure is ramping up like it does every August and I want traps out BEFORE they get bad, not after. But last year I used a homemade soda…

Day 3 of Formic Pro and there's a pile of dead bees at the entrance plus brood gaps — normal or did I cook my queen?

Third year, four hives in the North Carolina piedmont. Put Formic Pro (2 strips, full dose) on my worst mite hive Saturday evening. Daytime highs have been 84-86F, so ins…

Mid-winter down here in Victoria — cluster checks and timing a broodless oxalic, first varroa winter

G'day from the other hemisphere — while you lot argue about dearth feeding, I'm staring at four clustered hives in a Victorian winter. Fifth year, but this is my first pr…

Yellowjackets hammering my weak nuc — traps, reducers, what actually works before they finish it off?

Ontario, second year. My July nuc (5 frames, maybe 3 covered in bees) is under siege — yellowjackets patrolling the entrance all day, diving on returning foragers, and to…

Small-cell and foundationless as varroa control — does the evidence actually support it? Skeptic asking honestly

Eight years in Skåne, and every summer the same claim resurfaces at our club: regress your bees to 4.9 mm small-cell (or go foundationless for 'natural cell') and varroa …

Apiguard vs Formic Pro when it's 33-35C every day — are the temperature limits real or cautious lawyering?

Third year in North Carolina, four hives, mite counts creeping up (6-9 per 300) and I need to pick a treatment. Our forecast is 33-35C for the foreseeable. Formic Pro say…

Alcohol wash came back around 5% — what actually works in a dearth, and is formic safe in this heat?

Washed all six of my hives yesterday here in Oregon and my two biggest ones came back at 14 and 16 per 300 — call it 5%. Way over threshold, I know I need to treat now, n…

The bees that get you through winter are being raised right now — a reminder about August mite loads

22 years in and I still see the same heartbreak every spring, so forgive the soapbox. The colony that dies in January didn't die in January. It died in August. Your winte…

Chalkbrood back again after a fortnight of Perthshire drizzle — beyond ventilation, what actually moves the needle?

Seven years in Perthshire, six hives. One colony throws chalkbrood mummies every time we get a cool damp spell — and we've just had two solid weeks of it. White and grey …

Apivar timing math — working back from winter bees, what's the real drop-dead start date?

Six years in Flanders, and this season I'm switching to Apivar after two formic summers. I want to sanity-check my timing math because amitraz strips are a 6-week commitm…

Bald brood in patches — how do I tell wax moth damage from hygienic uncapping?

Second year in Galway, two hives. Found several patches of bald brood in my stronger hive yesterday — capped pupae with the cappings removed or perforated, white pupae vi…

Mite wash jumped from 2 to 8 per 300 right after pulling supers — did harvest cause this?

Second year, three hives in Ontario. Did alcohol washes in mid-June: 1, 2, and 2 per 300 across the three hives. Felt great. Pulled supers on the weekend and re-washed ye…

Oxalic vapour mid-summer with brood in the hive — why did one round do nothing?

Quebec, five years, six colonies. Alcohol wash on my worst hive came back at 11 per 300 last week — way over threshold, can't wait for fall. I vaporised oxalic once, wait…

Neighbour's colony died out and I'm scared it's AFB — what do I actually check before calling someone?

First year, two hives, Yorkshire. The retired chap two fields over lost his only colony a few weeks back and just told me over the fence that it 'dwindled and stank a bit…

Sugar roll undercounts mites — is killing 300 bees for an alcohol wash actually worth it?

Third year, 6 hives in the NC piedmont. My club teaches sugar roll because 'you don't kill bees', but I've been reading that sugar shakes recover maybe 80–90% of the mite…

Formic Pro: single-strip 10-day dosing vs the full 2-strip hit — heat ceiling and queen risk

Ants marching into my hive in a line — do the oil-cup stands actually work? Is cinnamon real?
