Removing the queen excluder in winter is generally recommended to prevent the queen from being separated from the cluster, which could lead to her death and the potential loss of the colony. During winter, bees form a tight cluster to conserve heat, and if this cluster moves above the excluder, the queen may not be able to follow. This separation can be fatal for the queen and detrimental to the colony. It is advisable to remove the excluder before the onset of frost or when overnight temperatures drop significantly, typically after the last honey flow when bees are no longer actively bringing in honey. Early removal poses no harm and ensures the queen remains with the cluster throughout the winter.
Key Points Explained:
-
Risk of Queen Separation:
- During winter, bees form a cluster to maintain warmth. If this cluster moves above the queen excluder, the queen may be unable to follow, leading to her separation from the colony. This separation can result in the queen's death and potentially the collapse of the entire colony.
-
Timing for Removal:
- The queen excluder should be removed before the first frost or when overnight temperatures begin to drop significantly. This timing ensures that the queen remains with the cluster as the bees prepare for winter. Early removal, especially after the last honey flow when bees are no longer actively foraging, is safe and beneficial.
-
No Harm in Early Removal:
- Removing the queen excluder earlier than necessary, such as after the last honey flow, poses no risk to the colony. In fact, it provides an added layer of security by ensuring the queen is not inadvertently separated from the cluster during the colder months.
-
General Advice:
- It is generally advised not to place honey stores above the queen excluder during winter. This practice helps prevent the cluster from moving above the excluder and reduces the risk of queen separation. Removing the excluder altogether eliminates this risk entirely.
By following these guidelines, beekeepers can help ensure the health and survival of their colonies through the winter months.
Summary Table:
| Key Point | Explanation |
|---|---|
| Risk of Queen Separation | In winter, bees cluster for warmth. If the cluster moves above the excluder, the queen may be left behind, risking her death and colony collapse. |
| Timing for Removal | Remove the excluder before frost or significant temperature drops, ideally after the last honey flow. |
| No Harm in Early Removal | Removing the excluder early, such as after the last honey flow, poses no risk and ensures queen safety. |
| General Advice | Avoid placing honey stores above the excluder in winter to prevent cluster movement and queen separation. |
