The Subterranean (Ground) Termites will have colonies in the ground; they build vertical tunnels that look like mud tubes above ground level so that they can search for food.
Subterranean termites can form tunnels through cracks in concrete, so slab homes are not exempt from these termites. Subterranean termites will die if exposed to air for an extended period; tunnels are used for transporting the food to the nest and protecting themselves. Subterranean termites need to soil contact to survive as opposed to the Drywood termites that only needs low moisture.
Drywood termites are more prevalent in the coastal regions. These termites may be carried in furniture from one region to another. Drywood termites are found many times in the attic wood structure.
