Which aspect should be checked during a post-application inspection to verify efficacy?

• A. Pest activity, signs of kill, residue, and drift; confirm no re-entry hazards; adjust if needed.
• B. The color of the pesticide label.
• C. The cost of the product.
• D. The time until the next scheduled application.

Answer: (A)

Post-application inspection focuses on confirming that the treatment did its job and that safety rules were followed. You look for evidence that pest activity has decreased and that there are signs the pests are dying, such as reduced feeding or visible dead insects, which shows the product is working. You also check residue to ensure the product was deposited where intended and remains within labeled limits, and you assess drift to confirm the spray stayed in the target area and didn’t affect non-targets. Re-entry safety is part of this check too—verify that the area is safe for people to return, with any required posting or intervals observed. If the results aren’t meeting expectations or safety concerns arise, you adjust the plan—recalibrate equipment, consider reapplication if allowed by the label, or switch strategies to better target the pest. The color of the label, the cost of the product, or when the next application is scheduled do not indicate whether the current treatment was effective.
