S ubterranean termites are the most destructive pest of wood in the United States, causing more than $2 billion in damage each year. Normally termites are beneficial,breaking down wood materials that otherwise would accumulate. When termites move into homes or other structures, problems ensue. Termites are not readily discovered by the owner of the structure since their activity is usually carried out behind wallboards,siding or wood trim.

    Termites are often confused with ants, especially when they are swarming. To tell ant swarmers from termite swarmers, there are certain key characteristics that can help in proper identification. First,look at the antennae. If the antennae are elbowed, or bent, then the insect is an ant. If the antennae are straight, the insect is a termite. Next look at the "waist" area.. Ants have a "wasp waist" that is constricted; termites do not have this constriction. If the insect still has the wings attached, compare the size and shape of the front and back wings. Termites have wings of similar size and shape, whereas ant wings are different in size and shape (generally, the hindwing will be smaller). If the insect has already shed its wings, look for a stub on the thorax (the second/middle body segment). Both termite and ant swarmers will shed their wings after mating,but only termites have a visible stub from where the wing was attached.
    Termite swarmers,ones that have wings and fly (the reproductives), are a good sign that termites are infesting your property. There are other signs of infestation you can look for, even if you do not have swarmers. Inspect window sills and cobwebs for shed wings. Walk around the structure and look for mud tubes going up the foundation, piers or utility entrances. Examine the building for damaged wood; any wood to soil contact is a potential entry site for termites. To locate wood that might be damaged, tap wood with a screwdriver. If the resulting sound is dull and thudding, the wood might need to be probed to determine damage.
    Subterranean termite wood damage is usually confined to soft, springwood growth. Tunnels tend to follow the grain of the wood. The tunnels are often lined with the same material used to build the shelter tubes, which looks somewhat like mud. The tunnels
