摘要：A beehive having a bottom board for separating mites from bees working in thebeehive. A permanently installed screen in the bottom board separates mites from thebees, and a sticky sub-board below the screen traps the mites to prevent re-infestation.

Notched members around the perimeter of the sticky sub-board prevent bees fromclimbing up into the beehive and prevent re-attachment. The sticky sub-board isaccessible from the rear of the beehive so that the entry and exit of the bees into andout of the beehive are not disturbed.
