In indoor pesticide applications, which safety requirement about re-entry should be followed?

• A. Follow REI and re-entry restrictions on the label.
• B. Re-entry is allowed immediately after application.
• C. Re-entry is not allowed ever.
• D. Re-entry depends on weather alone.

Answer: (D)

Re-entry safety after indoor pesticide application is controlled by the product label’s restricted-entry interval (REI). You must not enter an treated area until the REI has passed, unless the label specifies otherwise, and you must follow any entry requirements or required PPE stated on the label. Weather is not the determining factor for indoor re-entry—the label sets the allowed time and conditions for entry, sometimes including ventilation or PPE, to limit exposure. The idea that re-entry depends on weather alone ignores the established safety rules on the label and could put you at risk. So, the correct practice is to follow the REI and any re-entry restrictions shown on the label.
