The ant exterminator apparatus provides reservoirs for 3 different types of bait to thereby best lure pests, especially ants. The overlapping top removably fits over the base to allow pest entrance and egress. The top provides visible and mechanical base access without top removal and also negates bait spillage and exterior contamination of the apparatus by bait, thereby further ensuring against code violations. The apparatus is effectively and legally used both exteriorly and interiorly with respect to structures.
