The term "honey excluder" is a colloquialism used by some beekeepers to describe queen excluders, reflecting their observation that these devices can sometimes hinder honey production rather than facilitate it. This perspective arises from the bees' natural behavior and the physical constraints imposed by the excluder's design. While queen excluders serve the primary purpose of keeping the queen from laying eggs in honey supers, their narrow openings may discourage worker bees from efficiently storing honey above the excluder until the brood chambers are completely full. This can lead to reduced honey yields, prompting the critical nickname.
Key Points Explained:
-
Primary Function vs. Perceived Drawback
- A queen excluder is designed to separate the brood chamber (where the queen lays eggs) from honey supers (where honey is stored). Its mesh grid allows worker bees to pass but blocks the larger queen.
- The nickname "honey excluder" highlights an unintended consequence: worker bees may avoid traveling through the excluder to store honey in supers until the brood chamber space is exhausted. This delays or reduces honey storage in the intended harvest area.
-
Bee Behavior and Space Utilization
- Bees prioritize filling available space in the brood chamber before moving upward. If the excluder is perceived as a barrier, workers may delay or minimize honey storage in supers, opting instead to crowd the brood area.
- Some beekeepers report that colonies with local bred queens (smaller brood nests) adapt better to excluders, while wild-caught colonies may overproduce brood, exacerbating the "honey exclusion" effect.
-
Philosophical Divide in Beekeeping
- Pro-Excluder: Advocates argue excluders simplify honey extraction by keeping brood out of supers, yielding cleaner, lighter honey.
- Anti-Excluder: Critics believe they disrupt natural hive dynamics, reducing honey yields and stressing bees. This group often prefers brood-nest management techniques over physical barriers.
-
Practical Mitigations
- Upper Entrances: Adding an entrance above the excluder can reduce bee traffic through the grid, encouraging honey storage in supers.
- Observation-Based Adjustments: Beekeepers are advised to monitor colony behavior and adjust excluder use based on honey storage patterns and brood nest size.
-
Global Relevance and Experimentation
- Beekeeping practices vary widely by region and scale. Sharing experiences with excluders can help refine their use, balancing efficiency and hive health. New beekeepers are encouraged to test excluders while tracking outcomes to inform their approach.
By understanding these nuances, beekeepers can make informed decisions about whether excluders align with their goals—whether maximizing honey production or supporting natural hive behaviors. The debate underscores how even simple tools can profoundly shape the delicate ecology of a bee colony.
