How does physical barrier treatment work in termite prevention?

Physical barrier treatment in termite prevention is designed to create a protective separation between the soil and the structure. This method involves the installation of materials that termites cannot penetrate, such as steel mesh, sand barriers, or specialized polymer products. By establishing this barrier, it effectively restricts termites from accessing the building and eliminates their ability to infest wood structures from below the ground.

This proactive measure is particularly important in new construction, where barriers can be integrated into the design before the building is even completed. The effectiveness of physical barriers rests on their durability and resistance to deterioration over time, providing ongoing protection against termite activity without the ongoing application of chemicals.

In contrast, other methods like chemical treatments pertain to the application of substances that deter or kill termites but do not provide a physical impediment. Similarly, completely removing wood elements is impractical for most structures and does not address potential infestations. While traps can be used for monitoring and some control, they do not function as a preventative measure like physical barriers do.
