In many cases, early termite infestation shows no signs of insects or damage. As the colony grows, however, you may notice signs of termite activity that can include:
Discolored or textural changes in drywall.
Peeling paint similar to water damage.
A hollow sound when you knock on the wood.
Tiny holes in your drywall.
Buckling floorboards.
Loosening of floor tiles.
Squeaky floorboards.
Crumbling or damaged wood.
Mud tubes (tubes created by subterranean termites that connect the colonies in the soil to their food source – your home) around the foundation of the home.
