Signs of termite damage vary depending on the surface type affected, and appears primarily as cracks and sagging floors. Most termites feed on wood, and may cause cracks, large holes and sagging spots in wood surfaces on floors, walls and ceilings. Termites may eat through wood, causing large holes in the wood cavities, which makes wood hollow and more springy.
Termites are attracted to the cellulose found in most natural woods, and may cause damage to trees, shrubs and plants along with residences, office complexes and other structures. Termites may cause damage to insulation and lining in attics, garages and home walls. They can eat through plaster, books and newspapers, and may chew through swimming pool liners as well.
When targeting floors, termites often cause surface damage to laminate floors, which appears as cracks. Floors may also sag and blister, and have a spongier or springier feel. Termites can cause unexplained cracks in internal walls as they consume the cellulose within. On the surface, this damage appears as visible cracks. Termites also feast on wooden ceilings, rafters and beams in attics, causing cracks on ceilings and cornices. Signs of foundation damage caused by termites includes cracks in supporting cement bases. Termites can also cause sticking doors and windows, and may damage roof tiles, causing them to chip and break.
