A bedbug protective device has a carrier material, an attachment element coupled to the carrier material, and a sticky trap element coupled to the carrier material. The carrier material is impregnated with a bedbug repellent or insecticide. The carrier may be formed, for example, with its cross-section in a generally “C” shape with a back portion and first and second lip portions defining a channel, and with the first and second lip portions defining a longitudinal opening to the channel which is sized to permit bedbugs to enter the opening. The protective device first acts in a deterrent capacity, and secondly acts in a trapping capacity with respect to bedbugs.
