(14) The detector 1 is provided with a controller to control the operation of the sensor head 301 and to provide the indication of the presence of pests when sensed. The controller may be provided with a display screen and/or a speaker or similar to issue an audible sound upon detection of pests.

(15) Although not illustrated, this embodiment would also typically include a rechargeable battery power supply, a data storage component and possibly a jack or similar connection for headphones for the operator in the case of an audible indication of positive pest detection.

(16) The pest control system (100) also comprises at least one bait member in the form of a timber block (not shown) comprising a body with at least one receptacle to receive the conducting tracking material. In a preferred embodiment, the conducting tracking material comprises a metal in the form of gold foil which is which the inventor has found is attractive to pests such as termites as a source of food. The foil is breakable by the mouthparts of the termites which enable them to consume the gold. The gold foil is rolled up and placed in drilled holes in a wooden block which typically measures 13 cm long. The bait member with gold foil is then placed in an existing termite baiting station.

(17) As illustrated in FIGS. 3 to 5, a detector assembly may be provided in which the sensing head is mounted relative to a movement assembly to allow the sensing head to be moved over a ground surface.

(18) As shown in FIGS. 3 and 4, the sensing head 301 is provided on a wheeled cart 302 or similar that an operator can draw over the ground surface. The wheeled cart 302 has four wheels 303 which space the body of the cart 302 and the sensing head 301 from the ground during operation. An elongate handle or drawbar 306 is attached to one end of the cart 302 and a handle 304 is provided at the free end of the drawbar. This embodiment is particularly adapted for level areas.

(19) A controller 305 is provided relative to the drawbar 306, preferably at an upper end thereof to control the operation of the sensor head 301 and to provide the indication of the presence of pests when sensed. The controller may be provided with a display screen and/or a speaker or similar to issue an audible sound upon detection of pests.

(20) Although not illustrated, this embodiment would also typically include a rechargeable battery power supply, a data storage component and possibly a jack or similar connection for headphones for the operator in the case of an audible indication of positive pest detection.

(21) Alternatively, a hand-held device such as that illustrated in FIG. 5 may be provided with the sensing head 501 provided at the lower end of an elongate handle 502 with an upper portion 503 to be held by an operator and moved over the ground.

The controller may be provided with a display screen and/or a speaker or similar to issue an audible sound upon detection of pests. This embodiment is particularly adapted for areas which are not level, smaller areas of with more obstacles.

(22) The controller 305 may be detachable from the embodiment illustrated in FIGS. 3 and 4 to be attached relative to the handle 502 in the embodiment illustrated in FIG. 5.

(23) The preferred embodiment would typically include one or more additional complimentary pest identification and/or pest tracking modules operating on the principles of thermal detection, moisture detection, movement detection, conductivity detection and or radar such as ground penetration radar. The operator will typically use the controller 305 to switch between the modules or activate more than one module concurrently if necessary.

(24) In the preferred embodiments, the pests are typically detected using the conductive material that they have ingested. Detection of one pest is difficult but given the numbers that would usually be present, detection can be undertaken with more certainty. Once detected, the operator can then preferably use the one or more additional complimentary pest identification and/or pest tracking modules provided to track the movement of the pests through the ground in order to track the pests back to their nest. Depending on the one or more additional complimentary pest identification and/or pest tracking modules used, an indication of depth can be gained as well.

(25) In use, the bait member and conducting tracking material is placed in the vicinity of a structure to be protected such as a wooden house or wooden retaining wall such as an existing termite baiting station. The presence of the pest which has been consumed conducting tracking material is then detected in the vicinity of the bait member by the detector. The location of a nest of the pest is then confirmed by inserting a sensor probe into the location of the nest. Once the nest has been located Thus preferred embodiments of the present invention has the advantage over the prior art including more efficient eradication of pests by decreasing the time required to locate nests and by increasing the proportion of the pest colony that is eradicated.
