There are two kinds of Termites in Florida. Drywood and Subterranean. The Drywood don't eat through the wood, they eat right up until they see light then move on. You can easily put your finger through the thin wood left where they have been. Subterranean's come up from the ground and do pretty much the same damage. Problem is they are both treated differently for removal. Best thing is have a pest control come out and at least tell you which one you have.
