Owing to their wood-eating habits, many termite species can do significant damage to unprotected buildings and other wooden structures. Termites play an essential role as decomposers of wood and vegetative material. The conflict with humans occurs where structures and landscapes containing structural wood components, cellulose derived structural elements, and ornamental vegetation provide termites with a reliable source of food and moisture.
Their habit of remaining concealed often results in their presence being undetected until the wood is severely damaged, with only a thin exterior layer of wood remaining, which protects them from the environment. Sheetrock, commonly used in homes, has a covering paper, cellulose material, which is an excellent source of food for termites.
Termite colonies are always present in the ground; what keeps your home protected from a termite infestation is the chemical barrier underneath the foundation of your home.
