What should be done after trench application for termites is complete?

After completing a trench application for termites, the appropriate action is to put the clean soil back into the entire trench. This step is essential because it helps to restore the area’s original condition and prevents any potential hazards that could arise from leaving the trench open. Additionally, covering the treated area with soil helps to keep the insecticide in place and ensures that it can effectively penetrate the soil and affect any termites that may be present.

This practice also minimizes disturbances to the environment and surrounding structures. Filling the trench back with soil is fundamental to maintaining the integrity of the treated area and effectively sealing in the termiticide to provide ongoing protection against termites. In contrast, leaving the trench open, filling it with water, or covering it with plastic would not provide the same benefits and could lead to exposure of the termiticide, potential runoff, or other issues that may undermine the treatment's effectiveness.
