Horizontal Barriers may be established in the footing trenches. Vertical Barriers will be effectively in area around the bases. It involves applying a chemical barrier to the soil before the foundation is laid, which prevents termites from entering and infesting the building. After inspection of the area, the termiticide is applied by spraying or injecting it into the soil at a specified depth and concentration, depending on the type of termiticide and the local regulations. The treated soil is then covered with a layer of non-toxic material, such as sand or gravel, to protect the termiticide from sunlight and evaporation.
