What term describes the process of treating wood to protect it from pest damage?

The term that describes the process of treating wood to protect it from pest damage is "Preservation." This process involves the application of various chemicals or treatments to wood materials to enhance their durability and resistance against pests, such as termites and wood-boring beetles. Preservation is crucial in maintaining the integrity and longevity of wooden structures and products, preventing costly damage from pest infestations.

Fumigation refers to a specific pest control method where toxic gas is used to eliminate pests in an enclosed space, which is not specifically aimed at wood treatment. Infestation is the condition of being invaded by pests, which is the problem that preservation seeks to address rather than describe a preventive measure itself. Restoration involves repairing and renewing structures, but it does not encompass the protective treatments necessary for averting pest damage in the first place.
