Wood damage – Wood damage is a sure indicator that termites have taken hold in some parts of your home. Termites damage wood according to a distinctive pattern—when they eat, they leave nothing but bits of wood grain. Some termite species, however, are known to destroy wood from inside out, so damage may not be visible on the surface. In probing for an infestation, bang on the wooden parts, and listen closely. If the wood yields a thudding, dull sound, that could indicate the presence of termites.
Tunnels – Termites construct tunnels of mud outside brickwork, walls, concrete posts & slabs, and other dense structural materials. They use these tunnels when they can’t burrow through a specific object, such as a concrete wall.
