The timber inserts, unlike those in other systems available, are designed with vertical grooves and open voids running uniformally the length of the insert. These design features maximise the surface area of the timber which regulates the number of termites which will enter the station. They also provide tracks for foraging termites mimmicking termite workings in timber .Additionally the grain of the timber runs vertically upwards when the two timber inserts which fit in the station are positioned in line with the grooves and voids of the station. These innovative design features entice the foraging termites upwards into the the large open chamber to aggregate, when the Nemesis Termite Bait can be loaded.
