I am no expert of termite and would like to share with you all some information about termite.

Biology
Subterranean termites are ground-dwelling, social insects that live in colonies. A colony or nest of subterranean termites may be up to 12-20 feet below the soil surface to protect it from extreme weather conditions. Termites travel through mud shelter-tubes to reach food sources above the soil surface. The mature termite colony has three castes: a) reproductives (king and queen), b) soldiers, and c) workers. The colony reaches its maximum size in approximately 4 to 5 years and may include 60,000 to 2,000,000 workers. New colonies are formed when winged males and females from a parent colony emerge in flight or swarm. It is thought that a colony must be from between 2 - seven years of age before it can throw-off swarmers. The photo above is a dish of two types of termites. Subterranean on the left and drywood on the right.
Drywood termites need no link to the soil to obtain the water needed to support the colony. Although the colonies are smaller, they can still do a lot of damage to a home. And the worst thing about this type is that they are virtually impossible to detect and locate inside a structure. Most times, the extermination includes erecting a huge colored tent over the house or structure and pumping gas into the tent to fumigate the termite colony. This is a very costly process, and their is no residual benefit to having your home fumigated.
Evidence of Termite Infestations
* Wood damaged by termites always has remains of mud tubes attached to wood galleries or tunnels in an irregular pattern. The tunnels may contain broken mud particles with fecal materials. In the case of an active colony, white termites may be found in infested wood.
* The presence of flying winged males, females or their shed wings inside the building indicates an infestation.
* The presence of mud or shelter tubes extending from the ground to woodwork or on foundation walls also may indicate infestation. Workers travel periodically via shelter tubes to their nest to regain moisture and perform feeding duties. Each mud tube is approximately the diameter of a lead pencil.
How Old is the Damage?
Based on general feeding activity, it takes 3 to 8 years to cause appreciable damage. There have been some predictions that, under ideal conditions, a termite colony of 60,000 workers may consume a one-foot length of 2" x 4" pine in 118 to 157 days. In Texas, the extent of damage may be different because of extended feeding activity during the lengthy foraging season.
