Abstract
Abstract A trap for snails, slugs and the like has a base and a top cover which fits over the base. The base has a central upwardly extending support defining an upwardly opening bait receptacle. The base further has an annular upwardly projecting wall surrounding the central support. A generally horizontal planar bottom member of the base extends between and connects a lower portion of the central support and a lower portion of the annular wall. The top cover has a generally horizontal planar disk element and an annular lip that extends downwardly from the periphery of the disk element. The top cover further has a plurality of reinforcing ribs that extend from the underside of the disk element. The top cover is configured and dimensioned so that it can fit on top of the base and engage the central support and annular wall thereof, with the annular lip positioned radially outward from the annular wall. An annular gap between the lip, the wall and the disk element is sufficient in size so that snails, slugs or the like can crawl over the annular wall, through the gap and into a concealed poison chamber defined by the bottom member, the central support, the annular wall and the disk element. The bait receptacle communicates with the chamber through a space between an upper end of the central support and the disk element so that the odor of a quantity of bait deposited therein can permeate the chamber.
