If you suspect termite infestation, cut away a piece of wood at the site, if possible. Different types of termites leave distinctly different patterns of damage in wood.  Subterranean termites devour soft wood and eat along the grain. This produces a distinct honeycomb pattern in the wood. It is crucial to stop subterranean termites as soon as the infestation is discovered. One type, the Formosan termite, is especially voracious, due largely to its massive numbers. Formosan termite colonies can number in the millions. Left unchecked, these pests can inflict considerable damage on homes, fences and utility poles. Drywood termites excavate large sections of wood by chewing along and against the wood grain. Their appearance is serious, but less so than most subterranean types. Drywood colonies usually number only a few thousand members and usually take several years to reach that number. Even when they reach such numbers, the entire colony eats only about 1⁄2 pound (0.23 kg) of wood per year. If you look carefully, you may be able to find clues of termite infestations, even if you're unable to see the insect itself. Visual signs of a termite colony can include floors that buckle or sag, loose tiles, pinpoint holes in drywall, damaged wood crumbles easily, or wood that sounds hollow when tapped.   Shelter tubes running from the soil to above-ground wood. Termites feast on dead trees, which is what many houses are made out of. They build small, enclosed passageways, or tubes, to ensure safe access to the building. The tubes are made from soil, saliva, fecal matter and other material. The tubes indicate that termites are active. Drywood termites live inside wooden constructions, including structural timber, furniture and hardwood floors. Because they live inside the areas they feed on, they're almost never seen outside the colony. But they do leave signs of their presence. Drywood termites push fecal pellets, called frass, outside their tunnels and chambers. These wood-colored mounds accumulate on flooring under...
