Identifying Subterranean Termites
Region of US: All
Location in home: All
Though most common in the southern regions of the country, subterranean termites are found in every state except Alaska, and are responsible for the majority of termite damage in the United States. Requiring moisture from the soil to survive, subterranean termites build large colonies underground and then tunnel hundreds of feet to reach feeding sites. They also build these tunnels above ground using a mixture of saliva and soil to create protective mud tunnels along the walls and foundations of homes. If such mud tunnels are visible, homeowners are advised to contact a pest control professional quickly, as these tubes are a strong indicator of a serious infestation.
Additional signs of a subterranean termite infestation appear similar to water damage, with buckling wood, swollen floors and ceilings, and a moldy or mildewy scent being strong indicators. Because the subterranean termite diet consists only of softwood, damaged structures also tend to appear layered, and unlike their drywood and dampwood relatives, subterranean termites feed with the grain of wood, instead of against it. Subterranean termites are widely regarded as the most destructive type due to their large colony size and prolific tunneling ability, and if an infestation is detected, it is critical to act immediately.
