<p>A clearer board for a beehive comprises a shallow box-like structure having a top wall member which extends across the box and from the front wall towards the rear wall and a bottom wall member which extends across the box and from rear wall towards the front wall, the top and bottom wall members overlapping to form a tunnel between bee accesses in the top and bottom of the box. A gate in the form of an elongate resilient strip is pivotally mounted across the box in the tunnel and an external lever is provided to enable a user to operate the gate to allow bees to pass in either direction through the tunnel or to pass in only one direction as required. A beehive embodying such a clearer board is also disclosed.</p> |
