The primary purpose of soil treatment in termite prevention is to create a chemical barrier against termites. This involves applying specific pesticides or insecticides to the soil, which act as a protective buffer that termites cannot penetrate. By establishing this barrier, the likelihood of termites accessing and invading a structure is significantly reduced.

Soil treatment is a crucial aspect of termite control because it targets the primary entry point for these pests. The effectiveness of this method lies in the chemicals used, which can either kill termites on contact or repel them, ensuring that they do not find a pathway into homes or buildings.

While the other options may have relevance in different contexts, they do not pertain to the primary aim of soil treatment in termite prevention. Making soil fertile, promoting plant growth, and eliminating humidity do not directly address the threat posed by termites or mitigate their risk to structures.
