Supersedure Queen Cells (UK)
Not all queen cells mean swarming. One of the most common misunderstandings in beekeeping is confusing swarm cells with supersedure cells.
Supersedure is the colony’s way of quietly replacing a failing or ageing queen. Unlike swarming, it is usually a controlled and stable process, and in many cases, the best action is simply to leave the colony alone.
This guide helps you recognise supersedure and avoid unnecessary intervention.
What Is Supersedure?
Supersedure occurs when a colony decides its current queen is no longer performing well. This may be due to age, poor laying pattern, or reduced pheromone strength.
Instead of swarming, the colony raises a new queen to replace her, often while the old queen is still present.
How to Identify Supersedure Queen Cells
The key to identifying supersedure is context. There is no single “perfect” indicator, but a combination of clues builds the picture.
Supersedure cells tend to look similar to swarm cells, but their location and number are often different.
- One or two queen cells only
- Located on the face or middle of the frame
- Colony otherwise calm and stable
- Queen still present but underperforming
If you need help identifying stages, refer to the Queen Cell Guide.
Why Colonies Supersede Queens
Bees are very sensitive to queen performance. Even before a beekeeper notices a problem, the colony may already be reacting.
Common reasons include:
- Ageing queen (typically 2+ years)
- Poor brood pattern
- Reduced pheromone output
- Injury or damage to the queen
In many cases, the colony is simply correcting a problem before it becomes serious.
What Should You Do?
This is where many beekeepers go wrong. The instinct is to intervene, but supersedure is often best left alone.
If the colony is calm and the situation fits a supersedure pattern, the safest approach is usually to monitor rather than act.
- Avoid destroying supersedure cells
- Confirm presence of eggs or young brood
- Limit disturbance during queen replacement
- Allow the colony to complete the process

What Happens Next?
Once the new queen emerges, she will need time to mature, mate and begin laying. During this period, the colony may appear quieter than usual.
This is normal and not a sign of failure.
In some cases, both the old and new queen may be present temporarily, though this is not always observed.
The full timeline is explained in the Queen Cell Timeline.
Common Mistakes
- Destroying supersedure cells unnecessarily
- Assuming all queen cells mean swarming
- Repeated inspections during queen replacement
- Interfering without understanding colony condition
Over-management can cause more harm than the original issue the bees were trying to fix.
Supersedure Queen Cells FAQ
Do supersedure cells mean my colony will swarm?
No. Supersedure is usually a replacement process, not a swarm preparation.
Should I remove supersedure queen cells?
Generally no. Removing them can leave the colony without a functioning queen.
How many supersedure cells are normal?
Often one or two, sometimes a few more depending on conditions.
Can the old queen still be present?
Yes. In some cases, the old queen remains until the new one is ready.
Supersedure is one of the clearest examples of bees managing their own colony health. Understanding it allows you to step back when needed — and that is just as important as knowing when to act.
