Our beautifully constructed screened bottom boards give your hive ventilation in the warm months, and allow the mites to fall out the bottom away from your bees!

A corrugated filler board is included to slide underneath and close off the opening when desired. A grid chart is included to monitor mite fall if desired. Tip: spread cooking oil on the mite board to keep the mites in place.

Comes fully assembled.

Does NOT come with entrance reducer.
