Which type of wood is more likely to be damaged by termites in underground nests?

Softwood is more likely to be damaged by termites in underground nests because it typically has a lower density and is generally more palatable to these pests. Termites are attracted to wood that is easier to digest, and softwoods, such as pine, fir, and cedar, tend to have a softer texture and higher moisture content, making them a preferred food source.

In contrast, hardwoods, such as oak and maple, are denser and often contain compounds that can be less appealing to termites. Composite wood and plywood are manufactured products, often containing adhesives, which can make them less suitable for termites compared to natural softwood. Even though termites can damage any type of wood under the right conditions, softwood is more frequently targeted due to its inherent characteristics.
