A trap entangling vermin with adhesive material includes a pair of elongate ribs vacuum formed at central locations in the bottom wall of the tray carrying the adhesive material. The ribs are elongate and angled substantially at as degrees to the side walls positively to space apart the adhesive materials of two like traps placed in open faced relationship even when the traps are not in good registration. The ribs are hollow, opening to below the bottom wall, and have a uniform, substantially triangular shape along their length, with a radiused apex to increase the spot of contact between two engaging ribs. |
