When you find termites (such as we did with this home) you don't want to go rampant with bug killing sprays and such. They can give you some immediate comfort but it doesn't take care of the root problem. The Sentricon system we provide baits the grimey chewers who once located get baited & go back to the colony (which can be in the millions) to kill off significant members and cause the whole colony to die and thus stop chewing on your stuff. Note: this is a rather simplistic explanation but you get the idea I'm sure. Cool thing for you of the green mindset. Sentricon is completely green (before there was a green) option for keeping your house safe from these pests. http://www.allamericanpestcontrol.com
