Drywood termites are most prevalent in southern California (including the desert areas), but also occur along most coastal regions and in the Central Valley.
Drywood termites have a low moisture requirement and can tolerate dry conditions for prolonged periods. They remain entirely above ground and do not connect their nests to the soil. Piles of their fecal pellets/droppings, which are distinctive in appearance, may be a clue to their presence. The fecal pellets are elongate (about 3/100 inch long) with rounded ends and have six flattened or roundly depressed surfaces separated by six longitudinal ridges. They vary considerably in color, but appear granular and salt and pepperlike in color and appearance. Winged adults of western drywood termites (Incisitermes minor) are dark brown with smoky black wings and have a reddish brown head and thorax; wing veins are black. These insects are noticeably larger than subterranean termites.
Drywood Termites, are Sometimes they have to tent/fumigate the entire building. Depending on the physical shape of the structure, this can be quite difficult. The likely candidate for this is the drywood termite. Drywood termites do not (naturally) survive in the temperate zone. Drywood termites can, however, be imported from their native habitats, often in furniture and other wooden or decorative items. (section “1″ category pest / Structural Pest Control).
