What must a pesticide applicator provide to a customer after an application?

A pesticide applicator must provide post-application notification in writing to a customer to ensure clear and documented communication about the pesticide application that has occurred. This written notification typically includes important details such as the type of pesticide used, the amount applied, the date and time of application, and any safety precautions or re-entry intervals that should be observed. This requirement supports transparency and allows the customer to have a record of what was done, which is crucial for safety and compliance with regulations.

Written notification serves as a formal confirmation that an application took place, reducing potential misunderstandings and ensuring that customers are aware of any necessary safety measures they need to follow post-application. The other choices do not fulfill the regulatory requirement for documentation or may not provide sufficient detail or formal record keeping that written notification entails.
