The drywood termites are so-called because they establish themselves in wood that is not decaying, nor in contact with ground moisture and which appears to be perfectly dry. Gunn (1952) notes this species can exist in wood with as little as 2.8 to 3.0 percent moisture.
The termites of the genus, Incisitermes, formerly Kalotermes, the common drywood termites in Southern California, are pests in the attics of buildings where they maintain themselves without any soil connections whatsoever. Krishna (1961) recently split the genus Kalotermes into a number of genera.
Drywood termites are larger than subterranean termites and smaller than dampwood termites. The winged form and soldiers are up to 1/2 inch long. The pellets are regularly formed and when in abundance are to be found in dry sawdust-like piles. The cavities in the wood are clean and smooth as though the surface has been gone over with sandpaper.
