How Arizona Residents Can Tell The Difference Between A Subterranean Termite Infestation And A Drywood Termite Infestation

Termite species are divided into three categories: Subterranean termites, drywood termites, and dampwood termites. Unfortunately, Arizona is home to termite species from all three of these categories. There exists a few termite pest species in Arizona that are classified as drywood and subterranean termites, but only one dampwood species is active in the state. The most damaging subterranean termite species in the state include the arid land subterranean termite and the desert subterranean termite. The two most significant drywood species in the state include the dark western drywood termite and the light western drywood termite. All four of the above named species attack structures in great frequency in most areas of Arizona, particularly within the southern half of the state. There exists many ways for a homeowner to distinguish between drywood and dampwood termite species and the types of damage these species inflict on a home’s structural wood.

Subterranean termites are larger than drywood termites in terms of body size, and this goes for both swarmers (alates) and workers. However, most residents who discover termite damage in their home are unlikely to see individual worker termites, as they are active beneath the surface of wood where they remain out of sight for nearly all hours of the day. Unlike drywood termites, subterranean termites must make regular contact with ground soil for nourishment. In order to travel back and forth between structural wood and the soil, these termites build mud tubes that are usually visible along one or more sides of a home’s foundation. Drywood termite infestations may be relatively more difficult to notice, as they remain within wood at all times, making mud tubes unnecessary for these termites. But unlike subterranean termite infestations, drywood termite infestation can normally be pinpointed by finding piles of dry fecal pellets near areas of structural wood. Subterranean termites do not leave behind these fecal pellets, as they expel liquid waste within soil. Although subterranean termites are typically more widespread and destructive than subterranean termites, this is not the case in most western US states where experts consider the dark western drywood termite to be the most significant termite pest in the region, especially in Arizona.
