Which of the following is considered structural rather than agricultural pest control?

Structural pest control focuses on managing pests that affect buildings and other structures, as opposed to those that impact crops and agricultural land. Termite treatments specifically target wood-destroying organisms, which can compromise the integrity of structures like homes and commercial buildings. This aligns with the principles of structural pest control, as it aims to protect properties from infestations that could potentially cause damage.

On the other hand, soil fumigation, aerial spraying, and row crop spraying are all practices associated with managing pests in agricultural contexts. Soil fumigation is commonly used to treat pests present in the soil before planting, while aerial and row crop spraying are techniques that apply pesticides to crops to protect them from agricultural pests throughout their growth cycle. Therefore, these practices do not fall under the category of structural pest control, reinforcing that termite treatments are the correct identification of structural pest management.
