The best time to place a queen excluder is during a nectar flow when the hive is strong and active. This ensures the queen is confined to the brood chamber, preventing her from laying eggs in the honey supers, which keeps the honey clean and harvest-ready. The excluder should be installed after the colony has settled, typically when the queen is established and laying eggs consistently. Harvesting honey and removing the excluder usually occurs between late July and mid-August, aligning with the transition to winter hive management.
Key Points Explained:
-
Optimal Timing During Nectar Flow
- Place the excluder when there is a strong nectar flow, as this is when bees are most active in honey production.
- A strong hive ensures worker bees can efficiently move through the excluder without obstruction.
-
Queen Establishment and Colony Stability
- Wait until the queen is well-established and laying eggs consistently before introducing the excluder.
- If introducing a new queen, allow the colony to accept her and settle into a routine first.
-
Preventing Brood in Honey Supers
- The primary purpose of the excluder is to keep the queen in the brood chamber, ensuring honey supers remain free of eggs or larvae.
- This makes honey extraction cleaner and more efficient, especially in commercial beekeeping.
-
Seasonal Considerations
- Install the excluder in spring or early summer when the colony is expanding.
- Remove it between late July and mid-August during honey harvesting to transition into winter hive management.
-
Hive Strength and Worker Bee Movement
- A strong hive ensures worker bees can pass through the excluder without difficulty, maintaining honey production efficiency.
- Weak hives may struggle with excluders, leading to reduced honey storage.
-
Material and Fit Considerations
- Choose between plastic (lightweight, economical) or metal (durable) excluders based on hive needs.
- Ensure proper fit to avoid gaps where the queen might bypass the excluder.
By following these guidelines, beekeepers can maximize honey production while maintaining a well-organized hive structure.
Summary Table:
| Key Factor | Best Practice |
