What type of wood do subterranean termites prefer?

Subterranean termites primarily prefer softwoods like pine and spruce because these types of wood contain more cellulose and are generally softer, making them easier to digest. These termites have evolved to thrive on the resources found in softwoods, which provide the carbohydrates they need for energy. Softwoods are often more vulnerable to termite attack due to their physical properties and the availability of moisture, which termites require for survival.

While hardwoods, composite materials, and pressure-treated woods may demonstrate some resistance to termite damage, they do not offer the same level of attractiveness or palatability to subterranean termites as softwoods do. Hardwoods are denser and more difficult for termites to penetrate, and pressure-treated woods typically have chemical treatments that deter insect pests. Composite materials often include resins and other components that minimize the risk of infestation, making them less appealing to these wood-destroying insects. Therefore, softwoods are the preferred target for subterranean termite infestations.
