Reduce hive entrances in cold weather

Using entrance reducers in cold weather is a simple way to help bees maintain hive temperature and prevent brood chilling. Entrance reducers are devices that partially block the hive entrance, reducing the size of the opening. A smaller entrance makes it easier for bees to regulate hive temperature by limiting cold air influx and heat loss. Entrance reducers are particularly beneficial in early spring or late fall when temperatures fluctuate or during unexpected cold snaps. Reducing hive entrances conserves heat within the brood nest, minimizing the risk of chilled brood, especially in smaller or weaker colonies.
