Metal queen excluder with frame 425x510 mm

Queen Excluder DE – Metal 425 × 510 mm / Langstroth

Metal wire queen excluder measuring 425 × 510 mm is a proven tool for managing bee colonies in Langstroth hive systems. Its purpose is to reliably prevent the queen from passing into the honey super, so she remains in the brood chamber and does not lay eggs in the honey supers. The result is clean honey combs without brood and more convenient honey harvesting.

Main advantages for beekeepers and bees

The spacing of the openings is designed so that only worker bees can pass through the excluder without problems, while the queen bee remains in the brood chamber. The wire metal construction with smooth, rounded wires allows bees to pass through very easily – workers do not damage their wings on the excluder and there is no significant restriction of air flow in the hive. The beekeeper will also appreciate the long lifespan and easy maintenance: metal can be easily cleaned and disinfected (including boiling), which helps maintain high hygiene standards and reduces the risk of disease spread.

Recommended use and installation

For proper function, it is advisable not to place the excluder directly on the top bars of the frames, but to position it so that the bee space is maintained and bees can move freely underneath it. The wires of the excluder should be oriented parallel to the top bars of the frames – this makes it easier for bees to move smoothly between the brood chamber and honey super. The construction is solid, precisely manufactured and popular for its durability, especially in German practice. The excluder comes from the proven German beekeeping supplies supplier Mellarius and is a suitable choice for beekeepers who want reliability without compromise.
