Termites may be small, but the damage they cause can be extensive, expensive, and often hidden. Many homeowners only discover a termite problem when serious structural damage has already occurred.
Understanding the early warning signs of termites is the key to protecting your home or investment property before costly repairs are needed. This guide will help you identify the most common signs of termite activity and explain why early detection is essential.

You may also find: Piles of discarded wings near windows or doors, Termites attracted to light sources. This is a strong sign that termites are either inside your property or attempting to establish a new colony close by.
Termites consume timber from the inside out. As a result: Wood may look normal on the surface, Tapping the timber may produce a hollow sound, Timber may feel weak or crumble easily. This often indicates advanced internal damage that requires immediate professional assessment.
