In 1995, selected companies were authorized to use a new termite bait system produced by DowAgrosciences called the Sentricon® Termite Colony Elimination system. Designed to kill the colony rather than individual termites, this product gives us the long-term termite control we were accustomed to in the past. In using the Sentricon® system, a series of cylindrical stations are sunken in the soil around the structure that are used to detect termites, as they tunnel through the soil. A bait material that the termites eat readily is placed in the stations, but does not kill the termites quickly.
The objective is for the termites to consume the bait and do what they do naturally, which is to deliver the toxicant back to the colony. The termites exchange the food (poison) with each other until they die, which is when they shed their skin (about every 6 weeks). The process is designed to kill the entire colony rather than individual termites, so it is by design, slow. If there are live termites damaging the home, we use the shorter-lived, liquid chemical treatments in pinpoint applications, so we can stop the damage long enough for the bait in the outside stations to work.
