Queen cells: swarm cells, supersedure and what to do next

Queen cells can have different contexts; record what you see and seek timely, experienced advice.

Observe before acting

A queen cell is not enough, by itself, to tell you the colony’s intention or what action is right. Note how many cells you see, their location on the frame, whether they are charged or sealed, and whether eggs or young larvae are present. Record the date and colony condition.

Beekeepers distinguish swarm preparations from supersedure and emergency cells using the wider context and colony history. Beginners should not rely on a single visual rule or destroy cells reflexively: doing so can leave a colony without a viable queen or fail to address swarming.

What to tell your mentor

Have your last inspection record ready. Say whether you saw eggs, how many queen cells you noticed, whether any were sealed, and whether you saw a swarm leave. “Charged” means a cell contains developing brood, rather than being an empty cup. If you are unsure what you saw, say so; a clear photograph may help a mentor, but it cannot settle every question.

Cell position alone is not a reliable basis for choosing a response. Avoid repeatedly opening the hive while waiting for advice, and do not assume that removing visible cells has resolved the colony’s swarm preparations.

Get advice promptly

If you are unsure, contact your mentor, association or the NBU and consult current swarm guidance. If a swarm has already issued, follow your association’s advice. This page does not provide a diagnosis or a manipulation recipe. Continue to observe only as advised and record what happens.

Sting safety: A sting can happen even with protective clothing. Scrape a visible sting out promptly. If you have had a strong reaction, speak with your GP before beekeeping and do not inspect alone. BBKA getting started.
