What is the primary pest targeted by termites?

The primary pest targeted by termites is wood. Termites are known as cellulose feeders, which means they primarily consume materials that contain cellulose—a major component of plant cell walls. Wood is rich in cellulose, making it an ideal food source for these pests. Termites play a significant role in the ecosystem by aiding in the decomposition of dead trees and returning nutrients to the soil, but when they infest homes and other wooden structures, they can cause extensive damage.

The other options do not contain cellulose. Soil, while important for termites as it may provide moisture and support for their colonies, is not something they consume. Brick and metal do not provide any nutritional value for termites, as they consist of inorganic materials that termites cannot digest. Thus, wood stands out as the primary substance that termites actively seek out and target for feeding.
