Posting of Lawn and Ornamental Pesticide Applications 1

O. Norman Nesheim and Fred Fishel2

This document details the posting requirements for pesticide applications made to lawns and ornamental plants in Florida.


Florida law requires pesticide applicators to post notices of pesticide applications they make to lawns and exterior foliage (ornamental plantings) when these are part of the landscape around a building. This requirement is in the Florida Structural Pest Control Law (Chapter 482 F.S.), which is administered by the Bureau of Licensing and Enforcement of the Florida Department of Agriculture and Consumer Services (FDACS). The posting requirement applies to pesticide applications made by the following licensed applicators:

  • Commercial Pest Control Operators—Lawn and Ornamental Category.

  • Commercial Pest Control Operators—General Household Pest Control category, when a pesticide application is made to a lawn or exterior foliage to control certain household pests associated with the structure being treated.

  • Limited Certification—Lawn and Ornamental Category.

  • Limited Certification—Structural, when a pesticide application is made to a lawn or ornamentals to control certain household pests associated with the structure being treated.

  • Limited Certification—Commercial Landscape Maintenance.

The posting requirement does not apply to:

  • Pesticide applications made to golf courses, parks, athletic fields, and cemeteries. The Florida Pesticide Law (Chapter 487 F.S.) regulates pesticide application on these sites.

  • Pesticide applications made by homeowners to the lawn and ornamentals associated with their residence.

Specific Posting Requirements

  1. The notice must be posted in a conspicuous location at the time of the application of the pesticide to a lawn or exterior foliage. Figure 1 represents the required physical makeup of the notice.

  2. The minimum size of the sign is 4" x 5". It must be constructed of rigid, durable, weatherproof material with the background and lettering in contrasting colors. The size of print and symbol must be in conformity with the example in Figure 1.

  3. The business name of the licensee or the name of the limited certificate holder making the pesticide application must be clearly identified on the notice.

  4. The notice may be a part of a larger sign containing additional information.
