A beehive excluder, for preventing rodent and other animal intrusion, is configured to be coupled to the opening of a beehive and includes a body defining a first upper and second lower row of openings into a beehive. Each opening of each row is configured to allow the bees to land and proceed through the opening without traversing a vertical abutment. The body includes a dividing ridge extending the excluder's width, wherein a plurality of openings include vertical sidewalls extending from the dividing ridge and sloping toward the interior of the beehive. The body is a one piece molded structure and further includes clip members configured to couple the excluder to the beehive, wherein the clip members are formed by a plurality of cantilevered extension members extending into the beehive opening with upwardly extending detent members on distal ends thereof.
