A modular pest control system which includes structure that is specifically designed to capitalize upon the physiology and/or behavior of a wide assortment of pests to render the system more attractive to the pests. The system is modular in nature whereby it may be configured as desired or necessary to target any combination of one or more species of pests. The modular system preferably includes, at minimum, a first component in the form of a pest control device that may be releasably connectable to a second component. The first component may contain one or more materials or structural features for controlling any individual species or combinations of species of ground crawling pests, termites and rodents. The second component may be a releasable base for securing the first component to vegetation, building surfaces and materials, or targeted areas of soil. Alternatively, the second component itself may be a pest control device that may be releasably connectable to the first component and which anchors the first component to the earth.
