Equip your hives with new ventilation and feeding caps. A simple idea that minimizes feeding time and keeps the interior of the hive cool and dry.
Their screen does not allow the bees to pass through.
Designed for ANEL caps and hives but you can screw them in any type of hive after opening a 4cm diameter hole.
In very cold weather you can shut them with their special lids. Built from very durable material.
