Which term describes the process of termites eating wood and causing structural damage?

The term "infestation" accurately describes the process of termites attacking wood, leading to structural damage. Infestation refers to the presence of a large number of pests, like termites, in a specific area, indicating that they are actively feeding and reproducing. In the context of termites, an infestation means that a colony has established itself in or around a structure, often leading to the consumption of wood and gradual damage that may undermine a building's integrity.

While "destruction" might seem relevant because it refers to the end result of their feeding, it doesn't specifically address the ongoing presence and activity of termites within the wood. "Degradation" suggests deterioration but is broader and does not necessarily imply the active role of pests. "Fumigation," on the other hand, is a method used to treat infestations but does not describe the process of feeding itself. Therefore, "infestation" is the most precise term to convey the continual impact of termites on wood.
