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 (113, 313) positionable within the interior space of the station housing; an electrically conductive sensor disposed at least in part within the bait product (113, 313), the sensor comprising an electrically conductive filament; 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 send a signal exterior of the station housing indicative of the at least one electrical characteristic of the electrically conductive sensor; characterized in that the electrically conductive sensor comprises an encasement at least in part encasing the electrically conductive filament, 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. 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 (113, 313) positionable within the interior space of the station housing; an electrically conductive sensor disposed at least in part within the bait product (113, 313), the sensor comprising an electrically conductive filament; 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 send a signal exterior of the station housing indicative of the at least one electrical characteristic of the electrically conductive sensor; characterized in that the electrically conductive sensor comprises an encasement at least in part encasing the electrically conductive filament, 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. a bait product (113, 313) positionable within the interior space of the station housing; an electrically conductive sensor disposed at least in part within the bait product (113, 313), the sensor comprising an electrically conductive filament; 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 send a signal exterior of the station housing indicative of the at least one electrical characteristic of the electrically conductive sensor; characterized in that the electrically conductive sensor comprises an encasement at least in part encasing the electrically conductive filament, 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.
