What kind of damage do termites typically cause to structures?

Termites are known for causing significant structural damage to buildings and other wooden structures, primarily due to their ability to consume cellulose, which is found in wood and other plant materials. The correct choice highlights one of the most serious consequences of a termite infestation: the collapse of support beams.

When termites infest a structure, they often target load-bearing components, such as support beams and columns. These components are critical for the integrity of the building’s framework. Over time, termites can hollow out these beams, weakening their structural integrity to the point where they may no longer be able to support the weight above them. This can lead to structural failures, including partial or total collapse of floors or ceilings that rely on these beams for support. Understanding this risk is vital for homeowners and builders alike, as it emphasizes the importance of regular inspections and preventative measures to manage termite infestations.

In contrast, surface scratches and external cosmetic damage do not truly reflect the structural threat posed by termites. Similarly, minimal wear may occur with very light infestations but does not represent the destructive potential of termites when they are present in larger numbers.
