The Short Answer
Not always — it depends on your goal. If keeping brood entirely out of your honey supers matters to you, a queen excluder does that reliably. If maximizing honey flow into supers matters more, many experienced beekeepers skip it, since some worker bees are reluctant to pass through the excluder’s grid, which can slow supering during a strong nectar flow.
Arguments For
- Guarantees brood stays confined to the lower box, keeping your honey supers pure comb and honey with no eggs or larvae
- Makes it easier to locate the queen during inspections, since you know she’s confined to a specific box
- Genuinely useful when running a Flow Hive or similar system where you specifically don’t want brood in the harvest-frame area
Arguments Against
- Some worker bees hesitate to pass through the grid, which can slow how quickly bees move up into supers during a strong nectar flow — earning excluders the nickname “honey excluders” among critics
- Adds one more piece of equipment to manage, clean, and remember to place correctly
- Not necessary if you’re comfortable checking supers for stray brood before extracting, rather than preventing it structurally
Our Recommendation by Goal
- Honey production as the primary goal, established strong colony: skip it, or use it only once the colony has already started moving well into the super
- Using a Flow Hive or want guaranteed brood-free honey frames: use one
- New beekeeper still learning to identify brood vs. honey frames: a queen excluder can simplify things while you build confidence
Frequently Asked Questions
Does a queen excluder harm the queen?
No — it’s sized to let worker bees pass through while being too narrow for the larger queen, so it physically restricts her movement without injuring her.
Can I add a queen excluder partway through the season?
Yes, though it’s generally easier to install one from the start of supering rather than trying to add it once bees and possibly the queen have already moved into the super.
Do drones get restricted by a queen excluder too?
Yes — drones are also too large to pass through most standard excluder grids, so they’re confined to the lower boxes along with the queen.
