Which term corresponds to a time you must wait before entering a treated area?

• A. Re-entry interval
• B. Residue
• C. Overspray
• D. Drift

Answer: (A)

Re-entry interval is the waiting period after a pesticide is applied before people can safely enter the treated area. This time is specified on the product label to protect workers from exposure as residues settle or volatilize. The length of the interval varies by product and use, so you must check the label for the exact duration. After the interval has passed, entry is allowed (often with any label-specified PPE or other precautions).

Residue refers to the amount of pesticide left on surfaces after application, not to a required waiting time. Overspray describes spray that lands outside the intended target, not a compliance timing requirement. Drift is the airborne movement of pesticide away from the target area, which concerns off-target movement rather than when you may re-enter.
