- Head-banging is the loudest sound that termites make and is their way of communicating information. Termites are both blind and deaf, so they communicate using vibrations. Soldier termites are responsible for protecting the colony, so if they are disturbed, they will begin to bang their heads and large mandibles against the walls of the tunnels. Head-banging may sound like soft clicking or tapping to the human ear.
- Chewing sounds are very quiet and may sound like a continuous rustle or crunching noise. Termites never sleep, so they work 24/7 to find food and build tunnels. These chewing noises can most often be heard with large infestations that have moved close to the surface of walls.
- Wood damage from termites can take several different forms. As the termites eat and tunnel through the wood, it becomes weaker. This may result in loud, creaky floor boards. Termite damage can also make the wood sound hollow when tapped. Instead of the dull thud that is common with undamaged wood, hollow sounds indicate that there is a problem.
