Rtteri 8-Frame Plastic Queen Excluder 10-Pack (Yellow) — Flexible, Durable Mesh for Standard Hives

These yellow excluders come as a 10-piece bundle sized to suit standard 8-frame hives, offering a low-cost, long-lasting option for beekeepers who want to protect honey stores without stressing the colony. Molded from resilient plastic, they resist rust and rot and can be trimmed to fit slightly different hive profiles. The fine but uniform mesh keeps the larger queen from entering honey chambers while letting smaller workers access and store nectar and pollen.

How do these excluders fit into my hive setup?

The Rtteri excluders are cut from flexible plastic sheets sized approximately 19.88 x 13.98 x 0.12 inches, intended for 8-frame arrangements. If your hive dimensions vary slightly, the material trims cleanly and holds its shape, so you can adapt it to your boxes. Installation is simple: place the excluder between the brood box and honey super, ensuring the mesh faces upwards to block the queen.

• Designed for 8-frame hives; can be trimmed for custom fits.
• Fits between brood chamber and honey super for straightforward use.
• Thin 0.12" profile minimizes height loss in the hive stack.
• Ten-piece pack helps outfit multiple hives or serve as replacements.

Will the plastic material harm bees or wear out quickly?

These excluders use lightweight, non-corrosive plastic that does not splinter, rust, or rot like metal or wood options can. The material is flexible enough to resist cracking in normal handling and cleaning, and it’s easy to inspect visually for debris or residues. While durable, expect occasional replacement over several seasons depending on exposure and handling.

• Plastic construction avoids rust and splinter hazards.
• Flexible surface reduces breakage from normal use and transport.
• Easy to clean—wipe or rinse residues without special tools.
• Keep spare pieces on hand; ten in a pack covers multiple hives.

How does the mesh design separate the queen without blocking workers?

The excluder's mesh openings are sized to prevent the larger-bodied queen from passing while allowing worker bees to move freely between boxes. That selective barrier encourages the queen to remain in the brood area and keeps honey supers free of brood, simplifying harvest. The uniform perforations ensure minimal traffic disruption and help maintain normal foraging patterns.

• Fine, uniform mesh prevents the queen’s passage but permits workers.
• Helps keep brood out of honey frames for cleaner harvests.
• Promotes worker movement so hive activity and honey flow continue.
• Reduces the need for manual queen relocation during harvests.

Can I use these excluders for multiple hives and seasons?

Yes — the 10-piece set suits beekeepers managing several colonies or those who want spares for rotation and cleaning. The plastic is resilient for repeated use, and the low cost per unit makes it practical to swap excluders between hives or replace worn pieces annually. Store them clean and dry to extend service life.

• Ten-pack covers several hives or provides seasonal replacements.
• Affordable option for hobbyists and small-scale operations.
• Easy to store and transport; stackable and space-saving.
• Trim-to-fit capability adapts to slightly different hive types.

Who is this for: Beekeepers who run standard 8-frame hives and want an economical, low-maintenance queen-excluding solution will find the Rtteri 10-pack useful. It’s especially handy for hobbyists, backyard apiaries, and small commercial keepers who need multiple excluders for rotation or replacement. If you prioritize lightweight, rust-free materials and a ready-to-trim fit for honey harvesting, these excluders offer a practical, no-fuss option.
