Abstract

In a pest monitoring system ( 21 ) and method, a monitoring device ( 111 ) is located in proximity to a structure and includes a bait product ( 113 ) and a sensor ( 116 ) disposed within the bait product. The sensor includes a filament ( 118 ) encased within an encasement ( 119 ) and reactive to exposure to the environment exterior of the encasement such that at least one electrical characteristic of the sensor changes in response to such exposure. A communication member ( 121 ) is connected to the bait product in communication with the sensor to determine the at least one electrical characteristic and send a signal indicative of the at least one electrical characteristic. Based on a plurality of the signals received from of infestation of pests at the at least one monitoring device and a level of degradation of the bait product is determined.

First claim

What is claimed is:

1. A pest monitoring system comprising:
a station housing having an interior space; and
a pest monitoring device positionable at least in part within the interior space of the station housing and operable to monitor for the presence of pests within the interior space of the station housing, the pest monitoring device comprising;
a bait product positionable within the interior space of the station housing;
an electrically conductive sensor disposed at least in part within the bait product, the sensor comprising an electrically conductive filament and an encasement positioned within the interior space and at least in part encasing the electrically conductive filament, the encasement being separate from the bait product and configured to prevent exposure of the electrically conductive filament to the environment within the interior space of the station housing prior to the presence of the pests within the interior space and allow exposure of the electrically conductive filament to the environment within the interior space of the station housing upon the presence of the pests within the interior space, the electrically conductive filament being reactive to exposure to the environment within the interior space of the station housing such that at least one electrical characteristic of the electrically conductive sensor changes in response to exposure of the filament to the environment within the interior space of the station housing; and
a communication member disposed within the station housing in communication with the electrically conductive sensor, the communication member being operable to determine the at least one electrical characteristic of the electrically conductive sensor and to determine the level of exposure to the environment of the electrically conductive sensor based on the at least one electrical characteristic, the communication member being further operable to send a signal exterior of the station housing indicative of the at least one electrical characteristic of the electrically conductive sensor.

2. The pest monitoring system of claim 1 wherein the pest monitoring system is a termite monitoring system, the encasement being constructed at least in part of a termite acceptable material, the electrically conductive filament being exposed to the environment within the station housing upon termites chewing through the encasement.

3. The pest monitoring system of claim 1 wherein the electrically conductive sensor comprises a plurality of electrically conductive filaments electrically connected together to define a parallel circuit.

4. The pest monitoring system of claim 1 wherein the electrically conductive filament comprises defines a single continuous circuit in which the filament coils back and forth within the encasement.

5. The pest monitoring system of claim 1 further comprising an interrogator device operable to communicate with the communication member within the station housing to receive the signal indicative of the at least one electrical characteristic of the electrically conductive sensor.

6. The pest monitoring system of claim 5 further comprising a remote monitoring system operable to communicate with the interrogator device to receive the signal indicative of the at least one electrical characteristic of the electrically conductive sensor.

7. A pest monitoring system comprising:
a station housing having an interior space; and
a pest monitoring device positionable at least in part within the interior space of the station housing and operable to monitor for the presence of pests within the interior space of the station housing, the pest monitoring device comprising;
a bait product positionable within the interior space of the station housing;
an electrically conductive sensor disposed at least in part within the bait product, the sensor comprising a plurality of electrically conductive filaments electrically connected together to define a parallel circuit, and an encasement positioned within the interior space and at least in part encasing the electrically conductive filaments, the encasement being separate from the bait product and configured to prevent exposure of the electrically conductive filament to the environment within the interior space of the station housing prior to the presence of the pests within the interior space and allow exposure of the electrically conductive filament to the environment within the interior space of the station housing upon the presence of the pests within the interior space, the electrically conductive filaments being reactive to exposure to the environment within the interior space of the station housing such that at least one electrical characteristic of the electrically conductive sensor changes in response to exposure of the filaments to the environment within the interior space of the station housing; and
a communication member disposed within the station housing in communication with the electrically conductive sensor, the communication member being operable to determine the at least one electrical characteristic of the electrically conductive sensor and to determine the level of exposure to the environment of the electrically conductive sensor based on the at least one electrical characteristic, the communication member being further operable to send a signal exterior of the station housing indicative of the at least one electrical characteristic of the electrically conductive sensor.

8. The pest monitoring system of claim 7 wherein the pest monitoring system is a termite monitoring system, the encasement being constructed at least in part of a termite acceptable material, at least one of the electrically conductive filaments being exposed to the environment within the station housing upon termites chewing through the encasement.

9. The pest monitoring system of claim 7 further comprising an interrogator device operable to communicate with the communication member within the station housing to receive the signal indicative of the at least one electrical characteristic of the electrically conductive sensor.

10. The pest monitoring system of claim 9 further comprising a remote monitoring system operable to communicate with the interrogator device to receive the signal indicative of the at least one electrical characteristic of the electrically conductive sensor.

11. The pest monitoring system of claim 7 wherein the encasement comprises at least one of a coating and a sheath encasing each individual filament of the electrically conductive sensor.

12. A method of monitoring for the presence of pests in proximity to a structure, the method comprising:
locating at least one monitoring device in proximity to the structure, the monitoring device comprising a bait product, an electrically conductive sensor disposed at least in part within the bait product, the sensor comprising an electrically conductive filament and an encasement positioned within the monitoring device and at least in part encasing the electrically conductive filament, the encasement being separate from the bait product and configured to prevent exposure of the electrically conductive filament to the environment prior to the presence of the pests within the interior space and allow exposure of the electrically conductive filament to the environment upon the presence of the pests, the electrically conductive filament being reactive to exposure to the environment exterior of the encasement such that at least one electrical characteristic of the electrically conductive sensor changes in response to exposure of the filament to the environment exterior of the encasement, and a communication member connected to the bait product in communi
