What is a typical treatment focus when applying pesticides near structures?

• A. Treatment to soil or vegetation around structures.
• B. Indoor walls and ceilings.
• C. Water supply lines.
• D. Air ducts inside the building.

Answer: (A)

When applying pesticides near structures, the goal is to create a protective exterior barrier that pests must cross to reach the building. The typical focus is applying products to the soil or vegetation around the foundation, forming a residual barrier that deters or kills pests before they can enter. This exterior treatment targets entry points and helps reduce indoor exposure. Treatments on interior surfaces like walls or ceilings, or applying to water lines or air ducts, are not the standard near-structure exterior approach and can be ineffective or unsafe. So, treating the soil or vegetation around the structure is the best focus.
