Since 1994, Environ Control was 1 of 4 companies in Hawaii to be authorized to promote and offer The Sentricon Termite Colony Elimination System. We've been working with the system for 20 years now and have seen this system work time and time again. With the knowledge of subterranean termite biology and behavior, our technicians are able gain control of termites by working with the Sentricon System. The Sentricon System destroys the Termite Queen and her colony without disrupting your lawn, landscaping or foundation.
