摘要

Among the embodiments of the present invention is a system including a pest control device and a magnetic field source external to the pest control device. The pest control device has a bait operable to be consumed or displaced by one or more species of pest, a pest sensing circuit, and a monitoring circuit coupled to the pest sensing circuit. The monitoring circuit includes a device responsive to a magnetic field provided by the magnetic field source to output status information about the pest sensing circuit.
