Behavior, Diet & Habits
Understanding Subterranean Termites
Termites are broadly divided into three major termite groups:
Identification factors for subterranean termites are:
Alates (swarmers): Dark-brown to black in color, about ¼ to ½ inch long with two pairs of wings that are very close to being equal in length.
Workers: No wings, about ¼ inch or less in length and cream colored.
Soldiers: No wings, large mandibles (jaws), termite colony defenders, are creamy-white in color, but their head is often brownish in color.
Appearance of damaged wood: Since subterranean termites build their nests underground, damaged wood usually has an accumulation of soil or mud within the tunnels of the wood they are eating. Since subterranean termites only eat the softwood, damaged wood appears to be layered, the result of the workers not eating the hardwood portion. In addition, subterranean termites feed “with the grain” rather than across the grain, as do drywood termites.
Location of the nest: As their group name suggests, the nest is usually found below ground. Nests may be found above ground, but only when sufficient moisture conditions are available to support the above-ground nest and the colony is old and well established.
Live in colonies underground, from which they build tunnels in search of food; able to reach food above the ground level by building mud tubes; dependent on moisture for survival.
Diet consists of wood and other cellulose material.
Different rates of growth from egg stage to adult, depending on individual species; one primary queen per colony, which can lay tens of thousands of eggs in its lifetime, but eggs also can be laid by supplementary reproductives in an established colony.

Subterranean termites are found throughout the United States, but are relatively scarce in the colder states. They occur in greater numbers in warm, southern states. However they exist in every state except Alaska. They are most common in the humid, subtropical south between Florida and Southern California.
Termites Swarms: Formation of New Termite Colony

If you are constructing a new home, especially in a high-risk area, it is advisable that you obtain estimates from reliable professionals for termite-proofing your home. Pest control professionals are best equipped to take preventive measures, which could save homeowners from severe loss. Pest control experts will also be able to make recommendations that can help to prevent termite infestation.
There are over 2,300 described species of termite living today. Many of them are found in tropical and subtropical regions such as deserts and rain forests. However, there are more than 50 species that have been found living in the United States. Collectively, they are responsible for an average of $1 billion per year in property damages, infesting 350,000 structures.
These numerous species are broken down into subterranean termites, dampwood termites and drywood termites. The three types of termites differ in colony-building habits and preferred climate. Subterranean termites build large colonies underground, which are composed of elaborate tunnels and chambers. Worker termites then construct protective tunnels made of mud and saliva in order to reach above-ground wood. When subterranean termites eat wood, they fill it with soil to help maintain the humidity. If mud tunnels are visible on the walls or foundation of your home, it is highly likely that you are experiencing a subterranean termite infestation.
Subterranean vs. Drywood
Alternatively, drywood termites make their nests within cellulose-based materials such as lumber, siding and wooden trim. They require no soil contact and get their moisture from the wood. They also attack floors, furniture and books. Drywood termites can be more difficult to detect and aren’t typically noticeable until small piles of pellets (their feces) collect.
Subterranean vs. Dampwood
Dampwood termites locate their colonies in wood that is wet and even decaying. Wood that is in contact with the soil or wood that is constantly wet are ideal nesting sites for these termites. They are common in the Southwest and along the Pacific Coast. They are also found in Florida. If your home has leaky pipes or other moisture situations, it may be attractive to dampwood termites.

Termites cost Americans more than $5 billion in damage each year and most insurance plans don’t cover the damage.
