Metal queen excluder with frame 370x483 mm DE

Queen (Excluder) Grid DE – Metal 370 × 483 mm

Wire metal queen excluder in size 370 × 483 mm is a proven tool for colony management during the season. Its purpose is to prevent the queen from passing into the honey super, so she remains in the brood chamber and does not lay eggs in honey super combs. The grid openings are dimensioned so that worker bees can safely pass through, while the queen cannot. Wire metal excluders are among the most passable types for beekeepers. For proper function, it is recommended not to place the excluder directly on the top bars of the frames, but to leave space underneath for free bee movement. The wires of the excluder should be oriented parallel to the top bars. This is a design particularly popular in Germany – we can confidently recommend the excluder from beekeeping supplies supplier Mellarius.

Gentle Bee Passage and Stable Microclimate in the Hive

In practice, the wire construction has a significant advantage: unlike stamped or some plastic variants, the metal wire has a smooth, round surface. Workers thus do not fray or damage their wings when frequently passing between the brood chamber and honey super. The colony wears out less unnecessarily and can fully concentrate on the nectar flow. The thin wires also support good air circulation, which facilitates moisture ventilation and helps maintain balanced conditions throughout the entire hive.

Benefits for Beekeepers and Easy Cleaning

Using a queen excluder primarily provides clean honey super combs without brood, which significantly speeds up and simplifies honey harvesting. The metal design also excels in longevity and maintenance durability. While plastic can become brittle over time and crack during cleaning, the metal excluder can be easily cleaned mechanically from propolis and wax residues. You can also boil it or briefly flame it without concern, thereby performing effective thermal disinfection. The solid construction maintains its shape and preserves precise opening dimensions even after many seasons.
