Abstract

Among the embodiments of the present invention are pest control devices (1010, 1110, 1210) each operable to detect the presence of pests. The pest control device (1010, 1110, 1210) has a bait (1032) that is consumed or displaced by one or more species of pest, a pest sensing circuit (1052, 1152, 1252), and a monitoring circuit (1069, 1169, 1269). The pest sensing circuit (1052, 1152, 1252) can be altered by pest activity. The monitoring circuit (1069, 1169, 1269) detects this alteration and reports it automatically or in response to an external stimulus or interrogation to indicate pest presence.

Claims

1. A system, comprising:

a plurality of pest control devices each including;

a bait operable to be consumed or displaced by one or more species of pest;

circuitry including a pest sensing circuit, an activation device and an indicating device, the activation device being operable to selectively activate the circuitry as directed by an operator and the indicating device being operable to provide the operator information about the pest sensing circuit in response to activation of the circuitry with the activation device; and

a housing at least partially enclosing the bait and the circuitry, the activation device and the indicating device are mounted to the housing, the indicating device including a visual indicator and the activation device being a switch.

2. The system of claim 1, wherein the pest sensing circuit is carried on a substrate operable to be selectively connected and disconnected from the circuitry.

3. The system of claim 1, wherein the indicating device is a light emitting diode, and further including a transistor and a power source selectively coupled together by the switch.

4. The system of claim 1, wherein the pest sensing circuit includes an electrically conductive loop on a substrate configured to be altered by consumption or displacement by the one or more species of pest.

5. The system of claim 1, wherein the bait includes a pesticide.

6. The system of claim 1, wherein the bait is of a monitoring type selected for one or more varieties of termites.
