Provides that, following receipt of the information, the manager of the property shall provide prior notification to the pesticide-sensitive individual of all pesticide applications made by maintenance applicators to property within the pesticide notification area of that individual. Notification must be made at least ten hours prior to the scheduled application, or in the case of an immediate service call, the manager or maintenance applicator shall provide notification at the time of the application. The applicator must make the application within twenty-four hours following the date and approximate time stated in the notification. If the application is not made within twenty-four hours, the notification process must be repeated.

Requires notification to be provided in writing, in person, or by telephone and must disclose the address or the specific location on the property where the pesticide is to be applied and the date and approximate time of the application. In the event the manager of the property is unable to provide prior notification because of the absence or inaccessibility of the pesticide-sensitive individual, the manager shall leave a written notice at the residence of the individual at the time of the application.
