Devices, systems, and method to control pests

A method, comprising:

• installing a pest control device including a bait, a pest sensing member, and a monitoring circuit to monitor status of the pest sensing member;
• applying a magnetic field to the pest control device to stimulate operation of the monitoring circuit;
• and
• providing information about the pest sensing member from the monitoring circuit in response to said applying.

A pest control device, comprising:

• a bait operable to be consumed or displaced by one or more species of pest;
• a pest sensing circuit;
• a monitoring circuit coupled to said pest sensing circuit, said monitoring circuit including one or more indicators and a device responsive to an externally applied magnetic field to output status information about said pest sensing circuit with said one or more indicators;
• and
• a structure operable to position said bait, said pest sensing circuit, and said monitoring circuit in a predetermined spatial relationship relative to one another.

A system, comprising:

• a pest control device including 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 said pest sensing circuit;
• a magnetic field source external to said pest control device to selectively apply a magnetic field thereto;
• and
• wherein said monitoring circuit includes a device responsive to said magnetic field to output status information about said pest sensing circuit.

A pest control device, comprising:

• a bait operable to be consumed or displaced by one or more species of pest;
• a pest sensing circuit proximate to said bait;
• a visual indicator arrangement;
• a controller circuit operatively coupled to said pest sensing circuit and said indicator arrangement, said controller being programmed to automatically monitor said pest sensing circuit, detect a change of status of said pest sensing circuit, and provide one or more signals to said indicator arrangement corresponding to said change of status, said indicator arrangement changing from a first light emitting configuration to a second light emitting configuration in response to said one or more signals;
• and
• a structure operable to at least partially enclose said bait, said pest sensing circuit, and said controller circuit, said structure being arranged to position at least a portion of said indicator arrangement to be visible to an operator.

A method comprising:

• installing a plurality of pest control devices each including a respective bait for one or more species of pest, a respective pest sensing circuit, a respective visual indicator arrangement, and a respective controller circuit;
• visually indicating a first state of one of the pest control devices with the respective indicator arrangement;
• detecting a change in status of the respective pest sensing circuit with the respective controller circuit for the one of the pest control devices;
• adjusting one or more output signals from the respective controller circuit of the one of the pest control devices in response to the change in status;
• and
• visually indicating a second state of the one of the pest control devices with the respective indicator arrangement in response to said adjusting.

A method, comprising:

• monitoring with a plurality of pest control devices, the pest control devices each including a respective bait for one or more species of pest and a respective pest sensor;
• operating a hand-held interrogator to provide a stimulus to one of the pest control devices;
• and
• in response to the stimulus, receiving status information about the respective pest sensor from the one of the pest control devices.
