After completing a termite trench treatment, should you put the clean soil back into the trench?

• A. Only after a few days
• B. False
• C. True
• D. Only with supervisor approval

Answer: (C)

Backfilling the trench with clean soil is the proper step after applying termiticide in a termite trench. Doing it promptly helps seal the treated zone, keeps the chemical in place where it can work effectively, and restores the ground surface so the area looks and behaves normally again. Leaving the trench open can let wind and rain disturb the treated soil, potentially reduce the barrier’s effectiveness, and create erosion or safety concerns. The soil should be returned as part of standard procedure rather than waiting days or requiring supervisor approval for a deviation.
