Other termite species
There are numerous species of "subterranean" termites that differ by region. You should consult with local experts to find out the best way to protect structures in your area. However, in general, structures should be protected from subterranean termites by a combination of soil treatment (pre- or post-construction) and baiting. In areas with Formosan subterranean termites (Gulf Coast, US, Hawaii, northern Australia, etc.) you should be especially diligent because of this termite's potential for rapid and extensive damage.
Drywood termites occur mostly in arid and coastal regions (for example most of California in the US) where they to can do siginificant damage. This termite may built colonies above ground, entirely concealed in the structure and unlike their subterranean cousins, they do not need contact with soil. Often, damage to cabinets and furniture can be more significant than damage to structural timbers.
Dampwood termites also nest above ground but require wood that is continuously wet. Generally when the affected wood is made dry, such as by repair of a collapsed foundation, the termites disappear. However, structures in especially damp climates may be attacked directly.
