Shape and size:
Subterranean termite swarmers range from dark brown to black in color. They can grow up to ½-inch in body length and have two pairs of wings that are almost as long as their bodies. The worker termites are small in size and have no wings. The soldiers have elongated heads with mandibles and have an off-white colored body and brownish colored head.
Signs of a Subterranean Termite infestation:
Damage caused by subterranean termites can go undetected because they tend to destroy wood from the inside out. Their mud or shelter tubes are comprised of tiny pieces of soil, wood and debris. Other signs to look for include termite droppings and discarded wings. If you suspect you have a subterranean termite infestation, do not disturb their nests. They have acute survival instincts and are known to secretly move and cause damage to other areas of the house if they feel threatened.
