Unlike some other types of termites, however, they don't need access to damp conditions. Cellulose is a substance contained in the cell walls of plants that gives them their rigid structure. The reason is because redwood does not have as much sap as other softwood trees. Termites preferred southern yellow pine and spruce. When digested, cellulose provides termites with the nutrients they need to survive. They feed on products, which contain cellulose. Termites found southern yellow pine and spruce the most palatable and teak the least palatable.

Termites: Subterranean termites are the most commonly found termite species throughout Texas. | Certain factors make wood even more desirable to termites: high moisture content, softness, the presence of fungus or decay, and the absence of natural chemicals, resins, or oils that make wood resistant to decay and insects. These microorganisms enable termites to break down cellulose into digestible substances, thus enabling the insects to obtain life-sustaining energy and other necessary nutrients. Many species of drywood termites live in the southern half of the United States, with a range extending from California to North Carolina and southward.
