Of all insects that threaten homes in Florida, termites are the most feared. We have two prominent subterranean varieties here; the Eastern Termite and the Formosan Termite.  Both can cause major damage to homes, with the Formosan (FST) being the most numerous per colony (numbering in the millions vs thousands for other varieties) and therefore most destructive. Once established in an area FST has never been successfully eradicated.
