Control hive airflow and protect against intruders with our Entrance Reducer. This entrance reducer is made of wood that is durable and fits snugly into the hive entrance. The entrance reducer has two slots that can be used to vary the size of the entrance, depending on the season and the needs of your bees. The entrance reducer can help to keep the hive warm in winter, to prevent robbing and drifting in summer, and to deter mice and other pests. Use it to maintain the optimal conditions for your hive.
