The common termite species can be found in Hong Kong and Taiwan is called Formosan subterranean termite (Coptotermes formosanus). The other two common genus within subterranean termite family (Rhinotermitidae) are Reticulitermes and Heterotermes. The group as a whole is so-named because their activities are usually associated to some extent with the soil.
Subterranean termites invade your premises mainly by two methods. The first one will be termite swarm during early spring, a swarmer is a reproductive individual within the colony. Other names for reproductive individuals are the terms queen and king. Swarmers emerge from the ground or soil and mate in flight. They then drop their wings. Males die after mating. When mated females find suitable habitats (with moisture and wood), they are then ready to begin laying eggs and forming a new colony.
The second method is that, subterranean termites access aboveground wood in buildings through protected cracks and cavities. Normally, termites live in colonies underground, from which they build tunnels in search of food, they are able to reach food above the ground level by building mud tubes (mud shelter), as long as they can find tiny cracks or wood, they may start invading your home.
