Termidor, by BASF

A non-repellent termiticide that is applied as a treatment zone around your structure and under the crawl space if so constructed. Termidor is mixed with or injected into the soil in order to provide a long lasting continuous zone of treated soil. Some drilling through concrete slabs may be required.
The Sentricon *Termite Colony Elimination System by Dow AgroSciences, LLC

A technologically advanced system whereby monitoring stations are placed in the soil and placed approximately 10 feet apart around the entire perimeter of the structure to be protected. The stations are monitored on a regular basis for signs of termite activity. Once termite activity is detected a bait tube device containing NOVIFLUMURON also known as Recruit IV, is inserted into the monitoring station. Once baited the stations are checked more frequently until all of the termites are eliminated. Once elimination has occurred, each station is returned to the monitoring phase, and the process continues as before.
