During termite trench treatment, which soil-handling action is correct?

• A. Return clean soil to the trench
• B. Leave soil exposed
• C. Remove all soil permanently
• D. Cover with plastic

Answer: (A)

Returning the soil to the trench after applying termiticide keeps the barrier intact and protects people and property. When you excavate a trench to treat termites, the soil you remove forms the foundation around the foundation wall. Replacing that soil back into the trench restores the ground surface, seals the treated area, and prevents new entry routes for moisture or pests. Leaving soil exposed, removing it permanently, or covering it with plastic would create gaps, increase exposure risk, and fail to maintain a proper, continuous barrier. So the best practice is to place the soil back into the trench to restore the ground and complete the treatment.
