What To Do If You Find Queen Cells (UK Guide)

At a Glance – What Matters Most

What To Do First Before Touching Anything

The first thing to understand is that queen cells are not a single problem with a single solution. The bees may be preparing to swarm, they may be replacing a failing queen, or they may be trying to recover from sudden queen loss. The same-looking cell can mean very different things depending on the colony around it.

Before making any decision, slow down and record what you are actually seeing. Look for eggs and very young larvae so you know whether the colony is still clearly queenright. Count how many cells are present, note whether they are empty cups, charged cells or capped cells, and observe where they are positioned. Lower edges and bottom bars often support a swarm story, while one or two cells on the face of comb more often suggest supersedure. That pattern-based approach is strongly reflected in UK guidance from Wally Shaw and other beekeeper education material.

Empty Queen Cups – Usually a Sign to Watch, Not Act

Empty queen cups are common and, on their own, are not evidence that a colony is about to swarm. Colonies often build and remove cups as part of normal behaviour. This is why experienced beekeepers try not to overreact when they first spot them. A cup only becomes truly meaningful when it is charged with a larva and royal jelly.

If you find empty cups in an otherwise normal colony, the best response is usually to note them and pay closer attention at the next inspection. What matters is whether the colony is also strong, congested, backfilling the brood nest with nectar, and beginning to produce charged cells. BBKA-linked guidance and Wally Shaw both stress that cups and fully developed cells are not the same thing.

Capped Queen Cells – You Are Now on a Clock

Once a queen cell is capped, the process is already well underway. At that point, the beekeeper has less time to decide and act. A capped cell does not tell you whether the colony is swarming, superseding or recovering from queen loss, but it does tell you that the colony is further on than many people realise.

In swarm season, capped swarm cells can mean the colony is very close to issuing a swarm, and in some cases may already have done so. If you are at this stage, see Capped Queen Cells – What To Do. Once the process has reached the sealed-cell stage, timing is critical.

What the Colony Is Trying to Do

If you are going to make a good decision, you need to work out the colony’s likely intention. Swarm cells are part of a reproductive programme. Supersedure cells are usually a quiet replacement of a failing queen. Emergency cells are a rescue response after the queen has been lost.

Swarm cells are often more numerous, commonly found on lower edges or in recesses around the frame edges, and are associated with a booming colony that feels crowded or is backfilling brood space. Supersedure cells are often fewer in number, more often on the face of the comb, and more likely to appear where the existing queen is underperforming. Emergency cells are commonly raised from ordinary worker cells containing suitable young larvae after the queen has been lost. Wally Shaw’s guidance is especially clear that only true swarm cells mean the colony is intent on swarming; supersedure and emergency queen cells do not normally lead to a swarm in themselves.

What Action To Take in Each Situation

If the colony appears to be preparing to swarm, the response is not to keep knocking cells down and hope for the best. UK guidance is consistent that this is not a reliable swarm-control strategy. If you have identified a genuine swarm situation, the practical response is to use a swarm-control method you understand, reduce congestion where appropriate, and work to a clear follow-up plan rather than a vague hope that the impulse will disappear.

If the cells look more like supersedure, the safest response is often to let the colony get on with replacing the queen. Constant interference can do more harm than good. Record what you saw, note brood pattern and queen evidence, and inspect carefully but not obsessively on the next visit.

If the colony appears to be making emergency cells, the first question is whether there are still eggs or very young larvae. If not, the colony may have already moved beyond the stage where it can make further emergency cells from fresh brood. In that situation, careless destruction of the existing cells can leave the colony hopelessly queenless. That is one of the reasons emergency cells should never be treated casually.

Should You Cut Out Queen Cells?

This is one of the most misunderstood parts of beekeeping. The honest answer is that queen cells should not be destroyed automatically. Empty cups are usually left alone. Charged or capped swarm cells in a strong spring colony are usually a sign that proper swarm control is needed rather than repeated cell destruction. Supersedure cells are often best left alone. Emergency cells should not be cut out unless you have an immediate and better alternative plan, such as introducing a mated queen or following a deliberate requeening strategy.

Wally Shaw’s material is particularly strong on this point. It warns that destroying cells without understanding the stage of the process can make matters worse, especially if the colony has already swarmed and no suitable brood remains for replacement.

When You Should Split a Colony

A split becomes worth considering when the colony is strong, the brood nest is expanding fast, queen cells are appearing in a pattern consistent with swarm preparation, and you want to prevent the loss of a prime swarm. In practice, that often means multiple charged or capped swarm cells in a crowded colony during the main spring build-up.

The key is not to split too early without reason, but also not to leave a genuine swarm colony unchanged while hoping it will calm down. BBKA and National Bee Unit material both encourage beekeepers to learn one or two swarm-control methods well, rather than trying to improvise when queen cells are already present.

Horizontal or Vertical Split – Which Makes More Sense?

For most newer beekeepers, a horizontal split or classic artificial swarm is easier to understand because the physical separation between the units is obvious. You can see which box is on the original site, which box contains brood, and how flying bees are redistributed. National Bee Unit swarm-control material commonly uses this kind of practical movement-based setup.

Vertical methods, such as split-board arrangements or Demaree-style systems, can be very effective but usually demand more confident timing and closer follow-up. Wally Shaw’s swarm-control guide describes these methods in detail and makes clear that success depends on carrying out the later steps on time, not just the first manipulation.

For a beginner, it is usually better to learn one straightforward horizontal method thoroughly before experimenting with more technical vertical approaches.

What If You Cannot Find the Queen?

Not being able to find the queen is one of the main reasons people hesitate when queen cells appear. The important thing is not to let a frantic queen hunt turn the inspection into chaos. If you can still see eggs or very young larvae, that is often more useful evidence than physically sighting the queen.

National Bee Unit guidance includes swarm-control options specifically for situations where the queen cannot be found, which reflects how common this problem is in practice. The key is to work to a clear method and a follow-up plan, not to keep searching indefinitely and disturb the colony beyond reason.

What To Check 7 to 10 Days Later

This is one of the most overlooked parts of swarm control. The first intervention matters, but the follow-up often determines whether the whole thing succeeds. Wally Shaw’s guidance repeatedly stresses that many manipulations only work if the second inspection or second stage is carried out on time. In some systems, 9 to 10 days is a key window, with 12 days being the outer safe limit before unwanted virgins may emerge.

At the follow-up visit, you are checking whether the colony still has unwanted queen cells, whether the intended queenless portion is behaving as expected, whether a virgin may already have emerged, and whether your original objective has actually been achieved. This is also the point where poor record keeping starts to hurt, because if you do not know exactly what you did on day one, it becomes much harder to judge what you are looking at now.

Queen Cells Checklist – What To Record Before You Decide

• ✅ Number of queen cells seen
• ✅ Stage of each cell – cup, charged or capped
• ✅ Position – lower edge, side, face of comb or scattered
• ✅ Evidence of eggs or very young larvae
• ✅ Whether the colony feels congested or backfilled
• ✅ General colony strength and mood
• ✅ Whether the queen has been seen recently
• ✅ What action you took today
• ✅ What your follow-up goal is and when you will check again
