A beaver control device for use with a culvert pipe features a tubular frame having opposing longitudinal ends which are open and a plurality of openings spaced angularly about the frame. The openings provide alternative paths, in addition to the open ends of the frame, for water to pass through the device in an event that one of the open ends become obstructed. The device also features a plurality of transverse bars spanning across transversely opposing portions of an inner surface of the frame. The transverse bars are spaced along a longitudinal length of the frame and elevated relative to a bottommost edge of the frame which rests on the ground. The transverse bars are closer to the bottommost edge than to a topmost edge of the frame which is vertically opposite same. Elevating and spacing the transverse bars as described deters the beaver from passing through the device.
