Have you noticed many bees in tree canopies

Have you noticed many bees in tree canopies? This is a sign of swarming, a natural and strong instinct of a bee colony. The Beekeeping Association of Slovenia (ČZS) explains that swarming is essential for reproduction and species survival but can mean loss of honey yield, colony weakening, and extra work for beekeepers.

Swarming indicates an imbalance in the hive involving space, brood, young bees, forage conditions, and queen activity. The most common cause is overcrowding. In spring, colonies grow rapidly with the queen increasing brood, young bees multiplying, and nectar and pollen arriving. Without timely space addition, brood cells fill up, the queen lacks empty cells for laying, and nurse bees have less work, triggering behavioral changes.
