Queenless Hive: Signs, Test Frame, Laying Workers & Fixes

Queenless Hive: 7 Signs, the Test-Frame Trick, Laying Workers, and the Mite Problem That Looks Like Queenlessness

"I think I'm queenless" is the most common message a bee club gets from April through June, and about half the time it's wrong. Colonies go through normal broodless gaps after swarming and supersedure, virgin queens take weeks to lay, and a fall colony with spotty brood is far more often a mite problem than a queen problem. Here is how to tell, what to do, and how to avoid buying a queen you don't need.

The short version

No eggs for more than a few days, a loud roar when you open the lid, cranky bees, nectar backfilling the brood nest, and eventually multiple eggs per cell from laying workers. Confirm with a test frame of eggs from another hive: if they draw queen cells, they're queenless. And before you blame the queen for spotty brood in late summer, do a mite wash; parasitic mite syndrome mimics queenlessness, and that one is fixed with an oxalic acid vaporizer, not a new queen.

The Timeline You Need

Worker brood: egg 3 days, open larva about 6, capped about 12, emerging at 21. So if you see eggs, a queen laid within the last 3 days. If you see open larvae but no eggs, she's been gone (or stopped) 3–9 days. If everything is capped, 9 days or more. If there's no brood at all, three weeks or more.

A colony notices queen loss within about 15 minutes and starts emergency queen cells from larvae under 3 days old within hours. A new queen takes roughly 15–16 days to emerge, then a week or so to mate and start laying: about 3–4 weeks from loss to new eggs, if it goes well. Laying workers typically appear 2–4 weeks after the last brood pheromone fades.

Seven Signs of a Queenless Hive

No eggs. Look at the bottom of cells in good light. One egg, standing upright in the center, is a queen's. None at all, for more than a few days, is the first flag.
Brood disappearing in order. First no eggs, then no open larvae, then only capped brood, then nothing.
The roar. A queenless colony makes a distinctly louder, higher, more agitated hum when you crack the lid, and stays agitated instead of settling.
Temperament. Cranky, runny, following you. Nurse bees with nothing to nurse shift roles early.
Backfilling. Nectar and pollen stored in the middle of the brood nest where eggs should be.
Emergency queen cells. Cells built out from the face of the comb around a young larva, not hanging from the bottom bar like swarm cells.
Laying workers. Multiple eggs per cell, eggs stuck to the cell walls instead of the floor, a scattered pattern, and bullet-shaped drone cappings in worker comb. This is the late stage, and it changes the fix.

The Test Frame

Take a frame with eggs and very young larvae from a queenright hive, brush off the bees, and put it in the center of the suspect hive. Check in 2–3 days. If they've started queen cells on it, they are queenless. If they haven't, they have a queen (or a virgin) and you just saved yourself a purchase. If the colony has laying workers, repeat a frame of open brood every week; the brood pheromone gradually suppresses the laying workers and prepares the colony to accept a queen.

How to Fix It

Situation	Best fix
Recently queenless, still has open brood	Introduce a mated queen in a cage with candy release; laying in about a week. Or let them raise one from the test frame (3–4 weeks, riskier).
Queenless, all brood capped or gone, no laying workers yet	Mated queen, or a ripe queen cell from another hive. Give a frame of open brood with either.
Laying workers established	They rarely accept a new queen. Either combine with a queenright colony (newspaper method), or give a frame of open brood weekly for 2–3 weeks and then introduce a queen. Shaking out the bees in front of other hives is the old-school option for a small, hopeless colony.
Small and late in the season	Combine. A queenless nuc in September will not build a winter cluster.

When It Isn't the Queen: Parasitic Mite Syndrome

Every August and September, beekeepers requeen colonies that didn't need it. The symptoms of parasitic mite syndrome, spotty brood, larvae dead or "melted" in cells, chewed and sunken cappings, a shrinking population, increased supersedure, and a lack of eggs and young larvae, overlap almost completely with a failing queen. The Texas Apiary Inspection Service lists "lack of eggs and developing larvae" as a PMS symptom outright.

The tell: a mite wash over 3 per 100, bees with deformed wings, and white guanine specks in empty cells. A new queen in that colony lays into the same mite-infested comb and her brood dies the same way. Treat the mites first, on the right schedule, and reassess the queen after a clean brood cycle. Very often she was fine.

Queenless Myths

"No eggs means no queen." A virgin can take 2–3 weeks to start laying. Check for queen cells and count days before buying a queen.
"Spotty brood means a bad queen." Wash first. In late summer it's usually mites.
"Just drop a new queen into a laying-worker hive." They'll kill her. Open brood first, then a queen, or combine.

Rob keeps bees in Baltimore, Maryland, and owns Lorob Bees. He built and repaired his own corded oxalic acid vaporizers for years before becoming the primary US seller of the InstantVap, and he still picks up the phone when one needs service. Oxalic acid vaporization is the thing he cares most about in beekeeping, because it's the treatment that keeps hives alive without breeding resistant mites. More about Lorob Bees.
