A system for subterranean termite detection, measuring, concentration, collection, marking, tracking and suppression is provided by deploying a family of devices in the soil peripheral to objects subject to termite infestation. Each device is fitted with a signal port in its dorsal surface for inspectors to examine, and lateral ingress/egress ports for termites to enter. Subterranean termites are attracted to the devices, which are constructed of a termite food material. When entering termites seal the signal port they produce a distinctive visual change that is observable by an inspector from a distance. This alerts the inspector to the presence of termite activity within the device. The signal port may have an interior reflector for reflecting light directed threat to indicate that the signal port has been sealed by termites. The signal port may also have a mesh disposed thereacross to prevent unwanted obstruction thereof. Lateral ingress/egress ports may have a cellulose plug preventing organisms other than subterranean termites from entering. The food material of a given device may optionally be fitted with one or more chambers that are vacant or that contain separate food materials. The food material of the devices, and/or of the optional chambers, may be impregnated with toxicants that poison, growth regulators that induce desirable changes in, and /or markers detectable in, termites that feed thereon. When the optional chambers are left vacant they may serve as aggregation cavities for termite collection purposes, in which case a removable ventral plate permits withdrawal of termites contained therein.
