A system and method of monitoring and controlling cellulose-consuming pests in a predetermined location, providing for the use of an assembly that has a main body with a cylindrical upper portion and a lower portion continuously co-axially formed with the upper portion. The lower portion is formed as blades meeting at a lowermost point and defining a sharp bottom point that helps penetrate the soil in the selected location. A plurality of cellulose-containing bait units are detachably fitted in the lower portion and the upper portion. The bait units fitted in the lower portion are retained by the blade portions, which engage radial slots of the bait units. A moisture-retaining member is positioned in the upper portion above an uppermost of the bait units. A removable cap frictionally fittingly engages with the upper portion. The cap has an opening allowing water to be poured into the main body to moisten the bait units and make them more attractive to foraging insects. If consumption of the cellulose material
