Termites

Termites also known as white ants are soft bodied cellulose eating insects. Commonly used general groupings are: Subterranean, Soil-feeding, dry wood, Damp wood and Grass eating. Of these, subterranean and dry woods are primarily responsible for damage to human structures.

Cellulose forms the structural components of a plant. Wood is largely cellulose and lignin, being the perfect and most preferable meal for a termite. The termite obtains the cellulose from the wood and converts it into various sugars by specialized gut protozoan’s and in more highly evolved termites by specialized bacteria living symbiotically in the termite’s digestive tract.
