Abstract
A bait station (10) used in the reduction of pest populations is polygonal, having a first wall (14) that is straight and adapted to fit against a room wall, a second wall (16) with two portions at right angles adapted to fit in a room corner, two threshold portions (20,22) extending between the first wall (14) and the second wall (16), and third wall portions (18) oriented in a direction parallel to adjacent portions of the second wall (16) to define a right-angle passageway (34) between the second wall (16) and the third wall portions (18) and a bait containment chamber (40) between the first wall (14) and the third wall portions (18). The threshold portions (20,22) have pest access entrances (36,38) leading to passageway (34). An opening (40) to the bait containment chamber (32) is formed at the bend in the passageway (34). The passageway (34) makes the pest comfortable by providing a sense of easy access and retreat. The threshold portions (20,22) are angled to allow the pest equally facilitated access whether the bait station (10) is positioned against a corner created by the intersection of two walls or against a straight segment of wall.
