A system for subterranean termite detection, concentration and suppression is provided by deploying quasi-subterranean food masses configured in three functional forms tailored to each phase of a comprehensive program to detect, concentrate and suppress subterranean termite colonies. The detectors have subterranean entry/egress ports leading into lateral passageways connected to one or more vertical cavities joined to a signal port in the dorsal surface of the detector. Subterranean termites seal the signal port with soil detritus, producing a distinctive visual change in the dorsal surface of the detector. This alerts a human observer to the presence of the termites. The signal port may have a reflector in a cavity coupled to the signal port for reflecting light directed thereat to determine occlusion of the cavity by termites. The signal port may also have a mesh disposed thereacross to prevent unwanted obstruction thereof, and to encourage occlusion thereof by a termite's fecal material. The body member may also be impregnated with a unique substance detectable in termite fecal material to ascertain which other detectors have been visited by the termites, the substance providing a detector signature.
