Do You Actually Need a Queen Excluder?
Yes for beginners — always use one. It keeps brood cleanly separated from honey supers, making harvest simpler and honey purer. Experienced beekeepers sometimes skip excluders ("honey excluders" — because they can reduce honey yield if bees are reluctant to cross them), but for beginners the benefits outweigh this risk.
A queen excluder is one of the most debated tools in beekeeping. Old-timers will tell you that bees are reluctant to cross the metal grid, especially in cool spring weather, and that an excluder can cost you a full super of honey. That is true — but only in certain conditions. For a beginner, the alternative is far worse: discovering brood mixed into your honey frames at harvest, making extraction messy and honey storage complicated. A single frame of drone brood in a honey super ruins the batch.
💡 Pro Tip: If bees seem reluctant to move into a super with a new excluder, try rubbing the grid with beeswax or leaving the excluder in a hive for a few days before adding the super. This coats the metal with familiar hive scent and removes the "foreign object" barrier.
Types of Queen Excluders Compared
Metal excluders with wire grids last 10+ years and are the most durable. Plastic excluders are lightweight and affordable but warp in heat after 2–3 seasons. Wooden-frame wire excluders have the best bee acceptance. Slotted metal punched sheets are durable but bees cross them less willingly. Choose based on your climate, budget, and how many hives you run.
| Type | Material | Durability | Bee Acceptance | Price |
|---|---|---|---|---|
| Metal frame + wire | Galvanized steel | Excellent (10+ years) | Good | $$ |
| Plastic frame | Polycarbonate | Good (3–5 years) | Good | $ |
| Wire only (no frame) | Galvanized wire | Good (5–7 years) | Best | $ |
| Slotted metal (punched) | Galvanized sheet | Excellent | Moderate | $$ |
| Wooden frame + wire | Pine + wire | Good | Best | $–$$ |
Verdict: Metal excluders last longest. Wooden-frame wire excluders have best bee acceptance. Plastic is fine for occasional use but warps over time in heat. If you run multiple hives in a hot climate, invest in metal.

When and How to Use a Queen Excluder
Place the queen excluder directly on top of the brood box, below the first honey super. Add it at the same time you add your first honey super — once 7 of 10 brood frames are covered. Check regularly for damage that might let the queen through. Remove it in late fall before overwintering.
Placement & Timing
- Place directly on top of the brood box, below the first honey super
- Add at the same time you add your first honey super
- Wait until 7 of 10 brood frames are covered before adding the super
- Remove after the last honey super comes off for the season
- Do not overwinter with an excluder in place
Inspection Checklist
- Check for eggs in the honey super — indicates queen slipped through
- Inspect the excluder for bent wires or warped plastic gaps
- Hold up to light — bent wires are visible immediately
- Replace if grid spacing exceeds 4.5mm anywhere
- Clean propolis buildup at every harvest
⚠️ Warning: Never place a queen excluder below a brood box or between two brood boxes. It prevents the colony from expanding naturally and causes dangerous congestion. The queen needs unrestricted access to all brood frames to maintain healthy egg-laying patterns.
Cleaning and Maintenance
Scrape propolis buildup with your hive tool at every harvest. For heavy buildup, soak in warm water with washing soda for 30 minutes, rinse, and dry completely. Replace plastic excluders when warped or cracked, and metal excluders when wires are bent enough to change spacing. A damaged excluder is worse than no excluder at all.
Annual Maintenance Steps
- 1Scrape propolis buildup with your hive tool after removing from the hive
- 2For heavy buildup, soak in warm water + washing soda for 30 minutes
- 3Rinse thoroughly and dry completely before storing — rust forms on damp metal
- 4Inspect wires by holding the excluder up to bright light — bent wires cast shadows
- 5Replace plastic excluders when warped, cracked, or if spacing widens beyond 4.5mm
- 6Store in a dry, flat location over winter — do not stack heavy equipment on top
Frequently Asked Questions
It can slightly. Bees are sometimes reluctant to cross a cold or new excluder, especially in spring. Rubbing beeswax on the grid helps. In warm weather with strong nectar flow, acceptance is usually good. Most experienced beekeepers agree that the cleaner honey and simpler harvest outweigh the minor yield reduction in most conditions.
Match it to your hive frame count. 8-frame excluders for 8-frame hives, 10-frame for 10-frame hives. Do not use a 10-frame excluder on an 8-frame hive — gaps at the edges allow the queen to bypass it. Measure your box interior dimensions before ordering if you are unsure.
No — but she can slip through warped plastic that has been deformed by heat or weight. Inspect plastic excluders each season. If the grid spacing widens beyond 4.5mm, replace it. Metal excluders do not warp and are a safer long-term investment.
No. Remove the excluder after your last honey super comes off for the season. Overwintering with an excluder can trap the queen below the cluster as bees move up through winter stores. A trapped queen starves. Remove it in late fall and store it until spring.
