The advent of centrally heated homes has made it possible for termites to become a threat in virtually every region and state in the U.S.
On the average, there could be as many as 13 to 14 subterranean termite colonies per acre, which means that a typical home may easily have three to four colonies situated under or around it. And because there can be as many as 1,000,000 subterranean termites per colony, the threat of infestation becomes a very real one indeed.
Cause more damage to homes in U.S. than storms and fire combined; colonies can contain up to 1,000,000 members.
Subterranean termites nest in the soil to obtain moisture, but they also nest in wood that is often wet. They easily attack any wood in contact with the ground. If the wood does not contact the soil, they can build mud tunnels or tubes to reach wood several feet above the ground. These tunnels can extend for 50-60 feet to reach wood and often enter a structure through expansion joints in concrete slabs or where utilities enter the house.
Winged termites emerging from the ground out-of-doors near the house does not necessarily mean the house is infested, but it is a good reason to check further. Termites in the wood of homes or other buildings usually come from colonies already established in the soil.

BIOLOGY
Termites are small, ant-like insects. However, they differ from ants in that they feed off the cellulose in wood. Working largely unseen under the surface, they can tunnel through the wooden structural members in buildings and completely destroy them. Wood that comes in contact with the soil, such as the exterior trim or cladding on your home, provides a perfect point of entry for a termite colony.
Termites are social insects that live in colonies where labor is divided among a. They have reproductive and soldier castes. In many termite societies there is also a distinct worker caste, but the typical duties of workers( nest building and food gathering and feeding the reproductives and soldiers) are handled by nymphs as well. Workers and nymphs do all the work, soldiers sole job is to defend the colony.
Winged adults are often called swarmers, they are primary reproductives. They emerge from the colonies on colonizing flights during certain seasons in the year. After the flights, the male(king) and female(queen) will pair up, lose their wings and construct a small cell in the soil. They will mate,lay eggs, and rear the first group of workers. In colonies where the primary reproductives are not present, secondary reproductives (without color or functional wings)often occur in large numbers.
