Unlike drywood termites, they require contact with the soil or a constant source of moisture. They live in undecayed or decayed wood usually with a moisture content around 14% - 18%.
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. Because there can be as many as 1,000,000 subterranean termites per colony, the threat of infestation becomes a very real one indeed.
Subterranean termites cause more damage to homes in U.S. than storms and fire combined.
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 (plumbing penetrations) 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.
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 caste system. 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.
Reproductives can be primary or secondary. The secondary are found in mature colonies and serve as replacements if something happens to the primary reproductives. Winged reproductives (alates) are coal black to pale yellow-brown, flattened and about 1/4 to 3/8 inch long, with pale or smoke-gray to brown wings. Alates are also known as "swarmers”.
HABITS: Subterranean termites live in colonies underground, from which they build tunnels in search of food; able to reach food above the level of the ground by building mud tubes; dependent on moisture for survival.
Subterranean termite feeding follows the grain of the wood. Unlike drywood termites or other wood-boring insects, subterranean termites do not push wood particles or pellets (fecal material) to the outside, but rather use it in the construction of their tunnels. This debris, along with sand and soil particles, is used as a form of plaster.
They can form "secondary nests" above the ground called "aerial colonies". These independent nests may survive independent of the ground if there is a moisture source available. Such sources of moisture would be from a leaky roof, or plumbing leaks.
DIET: Wood and other cellulose material.
Subterranean termites feed on wood or other items that contain cellulose, such as paper, fiberboard, and some fabrics derived from cotton or plant fibers. Termites have protozoa in their digestive tracts that can convert cellulose into usable food.
