Detection and control of pests

A pest control device, comprises: a bait (132) operable to be consumed or displaced by one or more species of pest. A pest sensing circuit (150) is provided proximate to the bait. A controller circuit (116) is operatively coupled to the pest sensing circuit and to a visual indicator arrangement, the controller being programmed to automatically monitor the pest sensing circuit, detect a change of status of the pest sensing circuit, and provide one or more signals to the indicator arrangement corresponding to the change of status. A structure is provided to at least partially enclose the bait, the pest sensing circuit, and the controller circuit, the structure being arranged to position at least a portion of the indicator arrangement to be visible to an operator. The indicator arrangement changes from a first light emitting configuration to a second light emitting configuration in response to the one or more signals provided by the controller.
