Stainless Steel Queen Excluder Mellarius – 425 × 510 mm
Robust Solution for Daily Work in the Bee Colony
Wire stainless steel queen excluder in size 425 × 510 mm is designed for beekeepers who want a reliable, sturdy and long-term dimensionally stable tool. The excluder is made of stainless steel wires firmly welded into a stainless steel perimeter frame, so it does not twist or bend and easily withstands frequent handling during inspections. Stainless steel also resists moisture and propolis well and allows easy hygienic maintenance – unlike plastic variants, frequent replacement due to deformation is eliminated.

Clean Honey Combs Without Brood in the Honey Super
The main task of the queen excluder is to keep the queen bee in the brood chamber and prevent her from passing into the honey super. Thanks to this, the queen does not lay brood in the honey super combs and you will obtain continuous, clean honey combs without brood admixture during honey harvest. The excluder openings are designed so that only worker bees can pass through them easily, while the queen remains below the excluder. Smooth metal wires are usually easily passable for bees, which helps smooth operation between supers and gentler bee movement.
Recommendations for Proper Excluder Placement
For better bee comfort, it is advisable to install the excluder so that bee space is maintained and bees have enough space to move under the excluder. In practice, it has also proven effective to orient the excluder wires parallel to the top bars of the frames, which makes it easier for bees to pass into the honey super. This stainless steel excluder by Mellarius is among the precisely manufactured beekeeping supplies popular even in demanding operations and is suitable for both beginning and experienced beekeepers.
