Stainless steel queen excluder with frame 377x420 mm DE

Stainless Steel Queen Excluder Mellarius – 377 × 420 mm

Wire stainless steel queen excluder measuring 377 × 420 mm is a reliable tool for colony management and maintaining order in the hive. It is made of smooth stainless steel wires firmly welded into a solid stainless steel frame, so it does not twist or bend during work and easily withstands long-term use. The excluder effectively prevents the queen from passing into the honey super, so the queen remains in the brood chamber and does not lay eggs in the honey super combs. The result is cleaner honey harvest without brood residues in the honey super and significantly easier extraction.

Gentle Bee Passage and Easy Cleaning

The excluder openings are precisely calibrated to allow worker bees to pass through safely, but not the queen. Wire metal excluders made of smooth wires are among the best passable variants in practice – bees do not get caught on them and do not rub off their hair or wings, which can happen with some stamped plastic excluders with sharper edges. Stainless steel also meets high hygienic requirements: propolis and wax can be removed mechanically, by boiling in hot water, or by gentle flame treatment, which is a great advantage over plastic alternatives.

Recommendations for Proper Placement in the Hive

For comfortable bee movement, it is advisable not to place the excluder directly on the top bars, but to position it so that the bee space is maintained and bees have room for free movement under the excluder. The orientation of the wires is also important – ideally parallel to the top bars of the frames. This creates a natural "corridor" for smooth passage into the honey super and reduces unnecessary delays during nectar flow. These are proven wire excluders popular especially in Germany, where emphasis is placed on precision and long life of beekeeping equipment. We recommend the Mellarius excluder as a durable and practical solution for everyday beekeeping.
