Queen Mating Nuc Made of High-Density Polystyrene

🔧 High-density polystyrene 120 kg/m³

Material 2-2.5 times denser than standard mating nuc polystyrene. Delivers superior thermal insulation — key in small volumes where a sudden drop compromises brood —, greater resistance to intensive handling (doesn't chip when prying with the hive tool) and a longer life cycle after cycle.

📐 4 plastic frames with preinstalled foundation

Includes 4 plastic mini frames, each with a preinstalled piece of plastic foundation so bees draw wax quickly. One frame more than the standard Kieler/APIDEA 3-frame format, in the same 24 × 15 × 17 cm footprint. Saves time when setting up each batch.

⚙️ 4-position disc entrance and dual ventilation

Front rotating disc with four positions: controls access for bees, queen or drones separately, and allows full closure for introduction or transport. Dual adjustable ventilation: sliding mesh at the bottom + sliding panel at the front. Useful combination to prevent condensation in humid areas and to fine-tune airflow according to management phase (introduction, mating, transport).

🔄 Rear feeder chamber with anti-drowning design

Independent feeder compartment at the rear, separated by a queen excluder that stops bees from building comb inside. Design includes internal steps and a fine mesh so bees can climb down to the food without drowning in the syrup — a common failure mode of flat feeders in mating nucs. Rear position makes it easy to refill without disturbing the brood area.

⚠️ Important about mating: the PRO mating nuc is a management tool, it does not guarantee mating. Even with high-density polystyrene, success depends on enough young nurse bees, reserves in the feeder, mature drones available, favourable weather (~20 °C, clear sky, low wind) and unit health. The superior insulation reduces the risk of cold failure, but does not replace planning drone rearing about 5 weeks ahead or controlling varroa before stocking bees.
