Signs of white ants (termites) in your house often include hollow-sounding or damaged wood, as termites feed from the inside out. You may notice mud tubes on walls, foundations, or wooden structures, which termites use for protection and travel. Discarded wings near windows or doors are a common sign of termite swarming. Small holes, blistered paint, or sagging floors can also indicate hidden termite activity. Early detection is crucial to prevent serious structural damage.
