What structure can be a pathway for termites to reach wood in a building?

The correct answer, expansion joints, serves as a significant pathway for termites to access wood within a building. Expansion joints are designed to allow for the natural movement of building materials due to temperature changes and settling. They create openings that can be utilized by termites, providing them with a direct route to wooden structures such as beams, floors, and other elements within a building.

These joints are often sealed, but if they become compromised or improperly maintained, they can become vulnerable entry points for termites. Understanding these pathways is essential for pest control technicians, as it aids in the identification and prevention of termite infestations.

In contrast, electrical conduits and decorative moldings may not typically provide direct access to wood structures, as they are usually sealed and serve different purposes. Insulation material, while it may be present in the building, generally does not create a direct pathway for termites to reach wood; instead, it is more likely to impede access.
