How long do mites survive in a dead-out, and is comb from a varroa collapse safe to give to another colony?

Skåne, eight years. I've got the boxes from a colony that collapsed in September sitting in my shed — properly diagnosed as far as I can tell, heavy mite load, deformed w…

Velutina nest found 200 m from my apiary in late October — is destroying it this late still worth it, and who do I call?

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…

Pine honeydew still running in Muğla in October — how do you sequence mite control around a flow that ends in November?

Muğla, fifteen years, 60 colonies on pine. For anyone who doesn't know our system: the pine honeydew flow here runs from late summer into autumn, and in a good year we're…

A hive died and got robbed out before I noticed — did I just spread its mites round my own apiary?

Vermont, second year, four colonies on one stand. The smallest one has been limping since September and on Saturday I found it dead — a fist of bees on two frames, no que…

Wax moth got into brood comb from a dead-out — which frames are worth saving and which go in the fire pit?

Oregon, fifth year. I lost a small colony in late August to what I'm fairly sure was a mite-driven collapse, and I made the classic mistake of stacking the boxes in the s…

Do small hive beetles overwinter inside the cluster, and is a beetle trap still earning its place in October?

North Carolina, third year, six hives. Beetles were a proper nuisance in August — I had traps in every hive and was still squashing adults on the inner cover every visit.…

Shrews, not mice — what mesh actually keeps them out, and does a 9 mm mouse guard just let them stroll in?

Quebec, fifth year, eight hives at the edge of a woodlot. Two winters ago I opened a colony in March to find it dead, no mouse nest, no chewed comb, but a heap of dismemb…

Reading the natural mite drop on the tray after autumn treatment — what daily number sends you back in before winter?

Tyrol, 18 years, 24 colonies at two altitudes. My autumn treatment finished three weeks ago and I now have clean trays under all of them for a seven-day count. I trust th…

Black, shiny, hairless bees trembling at the entrance — chronic bee paralysis virus, or just robbing damage?

Eight years in Provence and this is a first for me. One of my eight colonies — one of the strongest, three deep boxes of bees — has, over the last week, started producing…

How do I know the colony is truly broodless before an oxalic treatment — cluster check, tray debris, or the calendar?

Third year in Uppsala, four hives, and I want to get the winter oxalic right this time. Last year I did an Api-Bioxal dribble by the calendar, mid-November, and my spring…

Found a mouse nest under the frames already in September — what do I do with the chewed comb and the nest?

Well. I was going to fit the mouse guards this weekend, and it turns out a mouse had the same calendar as me but got there first. Galway, second year, three colonies. Lif…

What mite count is actually acceptable going into winter — is 3 per 300 in late September good enough, or is 5 too many?

Second year in Vermont, three hives, and I'm confused about which mite number I should be aiming for right now. Ran Formic Pro in mid-August (two strips, 14 days, temps c…

European hornets (Vespa crabro) picking bees off my hive entrances — real threat, or leave them alone?

K-wing bees at the entrance — are tracheal mites still a thing, and how would I even check?

Bees with deformed wings crawling in the grass in front of the hive in late September — too late to save them?

Brown streaks down the front of two hives in mid-September — dysentery or nosema, and what can I do without fumagillin?
