Abstract: A platform for preventing crawling insects such as ants from having access to pet feeders, garbage cans, food stuffs and the like. The platform includes a removable, horizontal cover section, aligned with and parallel to a base, supporting a central, enclosed reservoir and surrounding moat barrier. A series of concentric, staggered walls and baffles runs outside of and parallel to the moat. The walls and baffles reduce evaporation of the liquid in the moat barrier, reduce contamination of the liquid by debris, and reduce spilling of the liquid if the platform is moved or knocked.
