In the past, the only method for termite elimination was a liquid treatment. However, due to changes in the residual life of the chemicals used, an entirely new concept of subterranean termite elimination has been developed and introduced. This system involves baiting termite colonies to eliminate this pest rather than the previous method which serves as a repellent. This program is called the Sentricon Colony Elimination System and was developed by Dow Agro Science Industries. The Sentricon program is backed with a Lifetime Guarantee. Once installed you will have an annual inspection of the home as well as inspections of the bait stations every ninety days. When termite activity is found in the monitoring devices, the in-ground station is baited. Upon feeding on these baited stations, the termites transport the bait back to the colony, thus leading to colony elimination.
