The Western Drywood termite
is California's second most important termite pest after the Western Subterranean termite. It is a native insect that has been here millions of years, mostly attacking trees along river washes. In California drywood termites are most prevalent in southern California and can be found infesting wood along the coast, and in the southern California desert. Because of the difficulty in detecting drywood termites and determining the extent of the damage done, do-it-yourself treatments are not recommended; homeowners should seek help from pest control professionals.
