Abstract: A rodent trap, particularly for mice, comprises a substantially closed container which includes a fixed stationary ramp surface extending from a position adjacent the lid of the container downwardly from one side of the container toward an opposed side at which it ends at a position adjacent to but spaced from the side surface. An upper portion of the ramp surface is roughened to give good grip to the rodent while a lower portion of the ramp is smooth to prevent or inhibit the rodent from turning or reversing once it has reached the lower end of the ramp surface. Bait is applied to the lower end of the ramp surface and to the inner surface of the side wall adjacent the end of the ramp surface. The depth of the container is sufficient so that it can receive the ramp while underneath the ramp is a quantity of water the depth of which is sufficient to drown the mouse. An opening in the lid adjacent the upper end of the ramp is of sufficient small size to prevent the entry of unintended larger rodents.
