A device for detecting an insect is described, the device comprising an insect harbourage having a first and second side wall, at least part of the first side wall being spaced apart from at least part of the second side wall so as to define an insect receiving zone therebetween. A first electrically conductable portion located on the first side wall and a second electrically conductable portion located on the second side wall is provided. The first and second conductable portions form at least part of an electrical component which is configurable between a first operative state in which the zone is void of any insects such that the electrical component has a predetermined first electrical parameter value and a second operative state in which the zone is in receipt of an insect such that the component has a second electrical parameter value differing to the first electrical parameter value.
