A termite-monitoring device and method for detecting the presence of termites and killing termites by exposing the termites to a termiticide, includes locating the monitoring device in a paving hole or in a termite lure located in the ground adjacent a building. The monitoring device has an integral termite indicator mechanism for indicating the presence of termites within the paving hole or termite lure that provides an aboveground visible indicator that termites are present. The termite indicator mechanism is actuated by a trigger mechanism with a termite food source that, when fed upon by termites, actuates the termite indicator mechanism to indicate the presence of termites. After the indicator has been actuated, a termiticide is introduced into the paving hole, the termite lure, and/or the adjacent ground to expose termites to the termiticide as the termites pass between a termite colony and the paving hole or termite lure and/or feed within the paving hole or termite lure.
