An electronic bait station utilising the disruption of an electromagnetic field to detect the movement of insects or small animals within the station. The bait station consists of a housing, with at least one cavity having an electromagnetic radiation element generating an electromagnetic field in the cavity, and an electromagnetic receiving element detecting the electromagnetic field. Movement of an insect or small animal in the cavity causes a change in the electromagnetic field, which is detected.The preferred bait station comprises an outer cavity and a coaxial inner cavity, each with an electromagnetic field. This arrangement allows the direction of movement of insects and small animals to be determined and minimises the occurrence of spurious signals.
