This entrance reducer fits over the entrance of a hive to prevent mice form entering while still allowing bees full access.

It is ideal for winterizing hives as it provides maximum protection against robbery.

The Entrance Reducer fits snugly in the opening between the bottom board and your first brood chamber to control the size of the entrance to the hive.

Perfect for weaker hives until they build up or to keep out some of the cold while still providing some air movement in winter.

Made of durable plastic material, light weight and portable.
