Subterranean termites are the most common form of termites, and their underground colonies can have as many as 1 million members. Unfortunately, subterranean termites also do the most damage to property and are some of the toughest pests to get rid of because they live between the earth and your home.You must treat termite infestation before severe property damage occurs. If significant damage has already occurred it may be time to call in a professional inspector. Subterranean termites are prevalent in most U.S. regions, particularly the Southeast.

Baiting Systems

Termite baiting systems work by enticing termites to feed on wooden stakes, cardboard or other cellulose material. This material, laced with a toxicant that is lethal to the termites, makes its way back to the colony and queen. The process is not a quick remedy, and the bait stations have to be monitored on a regular basis. Use extreme caution if you're using these systems in places that small children or pets can access. This is especially important if you have a crawl space below your home that cats and dogs visit often.

Soil Treatment

Treat the termite infestation by poisoning the ground. Termiticide is applied around the foundation's perimeter in a trench. Holes are drilled at strategic locations in the slab, along the building's foundation, and the termiticide is then injected using a special pump.


Fumigating -- often referred to as "tenting" -- the home will kill everything inside, including the subterranean termites. The building is enclosed in a tent and filled with a gas that eliminates all the oxygen inside. However, it will not kill the subterranean termite colony that is in the ground, and the subterranean termites will eventually return.

Direct Wood Treatments

Direct wood treatments are another option. Termiticides are applied directly to the wood in foam, gas or liquid form.


Help to avoid termite infestation by eliminating moisture in and around the home. Subterranean termites thrive in moist conditions. Avoid moisture accumulation around the foundation and crawl space areas. Have the property inspected on a regular basis to head off an infestation before it gets out of hand. The best time to call an insect, pest and termite sprayer is before the rainy season occurs. This way the sprayer can spray while everything is still dry, allowing the pesticide to soak in before the rain, and eventual moisture, comes.
