What Do Termites Eat? Feeding Habits and Main Food Sources Explained

Termites feed mainly on cellulose-containing plant material, and common targets include dead wood, bark, tree stumps, fallen leaves, humus and various plant residues. Their most typical food is woody material, so wooden beams, wooden floors, furniture and even books and paper products in houses can all become targets of infestation. This is one of the reasons termites are regarded as important pests.

Termites themselves cannot directly digest cellulose. Most species rely on protozoa and microorganisms symbiotic in their guts to break cellulose down into nutrients they can absorb and use. Some species also cultivate fungi in their nests and use the fungal growth as a food source; these termites play a clear role in the decomposition of dead branches and fallen leaves.

The feeding habits of different termite groups vary. Some prefer to feed on the cortex and xylem of living trees, some like to feed on humus in the soil, and others feed exclusively on the fungus gardens in their nests. Within a termite colony, foraging work is mainly carried out by worker termites, which bring food back to the nest to feed soldiers, young termites and the queen; the survival of the entire colony depends on the foraging activity of the workers.

Understanding termite feeding habits helps in judging the scope of damage and planning control measures. When storing paper, fabric, wood products and other cellulose-containing items in daily life, keep them as far as possible from wall bases and damp ground. Once holes, mud tubes or mud sheeting are found on wooden components, the source of the termites should be traced promptly and handled with scientific control methods to minimize losses.
