How to Introduce a New Queen Bee and Check Acceptance
Introducing a new queen is one of the most important—and sometimes most nerve-racking—jobs in beekeeping. Success depends less on rushing the process and more on preparing the colony properly, giving the bees time to adjust and recognising the difference between curiosity and aggression around the cage.
This guide explains a practical approach for UK beekeepers introducing a mated queen and checking that she has been accepted. Always follow the instructions supplied with your queen, as the recommended release method may vary with the cage and the condition of the colony.
Before introducing a new queen
First, be certain that the colony needs one. A colony that already contains a queen—even an unmated or failing queen—may reject a replacement. Check carefully for the existing queen, eggs and very young larvae. Look through the frames methodically and inspect the sides and floor of the hive as well as the brood combs.
Remove the old queen before introducing the replacement. The colony should also be checked for queen cells. If viable queen cells remain, the bees may favour their own developing queen and reject the caged one. Remove the cells only when you are confident about the colony’s situation and your chosen requeening plan.
Signs that appear to suggest queenlessness are not always conclusive. A lack of eggs may simply mean that a queen has recently emerged, has not yet begun laying or has temporarily slowed down. If you are uncertain, seek help from an experienced beekeeper before committing a valuable new queen.
Choose the right conditions
A calm, settled colony with adequate food is generally easier to requeen than one affected by robbing, starvation or repeated disturbance. Work gently and avoid introducing a queen during poor weather if the hive cannot be handled without chilling brood or causing unnecessary disruption.
In late summer and early autumn, natural forage can be limited. If stores are short, a suitable bee feed may help the colony remain settled, but feeding should be based on the colony’s actual needs and carried out carefully to avoid encouraging robbing. Hagens stocks bee feed, including IdealBee Classic Bee Syrup.
September can still provide an opportunity to replace a poor or ageing queen with a young, mated queen before winter, provided the colony is healthy, strong enough and the weather remains suitable.

How to introduce the queen in her cage
- Keep the queen caged. Do not release her directly into the colony. The cage protects her while the workers become accustomed to her pheromones.
- Position the cage close to brood. Place it securely between brood frames where nurse bees can reach the mesh. The cage must not be crushed when the frames are returned.
- Check the cage orientation. Follow the supplier’s instructions. With many cages, the candy outlet is positioned so that a dead attendant cannot block the exit.
- Allow time for adjustment. Some introduction methods keep the candy covered initially before allowing gradual release; others are supplied ready for candy release. Use the method specified for your queen and cage.
- Close the hive carefully. Avoid repeatedly opening the colony, as disturbance can interfere with acceptance.
A queen introduction cage can also be useful when a beekeeper needs a reusable cage for a planned introduction method.
How to tell whether the bees are accepting her
Before allowing release—where the chosen method includes a separate acceptance check—observe the workers through the cage mesh.
Encouraging behaviour includes bees standing calmly on the cage, feeding the queen through the mesh and moving aside easily when gently brushed. They may show interest without appearing frantic.
Warning signs include workers tightly gripping the cage, biting at the mesh, bending their abdomens as if trying to sting or forming a tense cluster that is difficult to move. This behaviour can mean the colony is not ready to accept her. Possible reasons include another queen, an overlooked queen cell, laying workers, prolonged queenlessness or stress within the colony.
Do not judge acceptance from the number of bees on the cage alone. A group of calm, attentive bees can be positive; a smaller number behaving aggressively can indicate a problem. If in doubt, keep the queen protected and reassess the colony rather than forcing an immediate release.
When should you check for eggs?
Once the queen has been released, give the colony time to settle. Avoid searching for her immediately or opening the hive every day. A careful inspection after roughly a week is often more useful, although weather and the queen’s circumstances can affect how quickly she begins laying.
Look for eggs and small larvae in a developing brood pattern. If the queen is marked, seeing her provides additional reassurance, but finding her is not essential if fresh eggs and normal colony behaviour are present. Continue to handle the frames gently; a newly introduced queen can still be vulnerable during the settling-in period.
Common reasons for queen rejection
- The original queen is still in the hive.
- The colony contains an overlooked queen cell or virgin queen.
- The new queen is released too quickly.
- The colony has been queenless for a long time or has developed laying workers.
- The colony is weak, hungry, being robbed or otherwise stressed.
- The hive is disturbed repeatedly during the introduction period.
- The introduction method supplied with the queen is not followed.
What if the introduction fails?
If there are no eggs after allowing a reasonable settling period, inspect carefully before assuming the queen has been lost. Weather, disturbance and the queen’s condition can delay laying. Check again for queen cells, signs of another queen and laying-worker activity.
If the queen is missing or has been rejected, avoid repeatedly adding replacement queens without finding the underlying cause. Combining a persistently queenless or very weak colony with a suitable queenright colony may sometimes be the better option, but only unite healthy colonies and use an appropriate method.
Final advice
Successful queen introduction starts with an accurate assessment of the colony. Confirm its queen status, remove competing queen cells where appropriate, protect the new queen in her cage and give the bees time to accept her. Patience and minimal disturbance usually offer a better chance of success than trying to hurry the process.
