The present disclosure provides an apparatus for indicating pest activity that includes an activity indicator and an activity sensor. The activity sensor includes a substrate that is a material attractive to a target pest species, and a sensing element formed on and/or within the substrate. The sensing element is couplable to a power source and the activity indicator, and outputs a signal to the activity indicator. The signal is influenced by pest activity on and/or within the substrate, and the activity indicator indicates a state of the signal received from the sensing element. The state of the signal changes responsive to deposit of a pest excretion on the sensing element. The present disclosure also provides a pest activity reporting system incorporating the apparatus that conveys a state of the signal to a remote location. The present disclosure also provides an activity sensor for use in the apparatus.
