Termites generally do not live in sewer lines. They prefer wood, cellulose, and damp, decaying organic material found in wood structures or soil. Sewers are typically inhospitable because they are dark, damp, and contain waste, which is not suitable for termites’ habitat. However, termites can sometimes access sewer lines through cracks or damaged pipes if there is nearby wood or organic matter. While it’s uncommon, termites can be indirectly associated with sewer lines if there is wood debris or moisture around the system. Proper home maintenance and sealing potential entry points can help prevent termite intrusion.
