In 1997, the Legislature amended the Structural Pest Control Act to give some applicators the option of licensing with Structural Pest Control Board (SPCB) or Texas Department of Agriculture (TDA). As of Sept. 1, 2007, the SPCB became the Structural Pest Control Service (SPCS), a part of TDA.

For persons who perform pest control work on growing plants, trees, shrubs, turf, other horticultural plants or rights-of-way can license with TDA in the Ag or structural categories. These applicators follow different laws and regulations, due to Agency Statutes.

The Texas Legislature established the Texas Department of Agriculture (TDA) in 1907. The Texas Administrative Code (TAC), Title 4, Part 1 governs the Agency to promote production agriculture, consumer protection, economic development and healthy living.

The Texas Department of Agriculture is designated as the state’s lead agency in the regulation of pesticide use and application.  TDA is responsible for licensing and training pesticide applicators, overseeing worker protection, registering pesticides for sale in the state and working to minimize unnecessary impacts to agriculture while enhancing protection of endangered and threatened species.

The Texas Department of Agriculture (TDA) licenses pesticide applicators that use restricted-use and state-limited-use pesticides and regulated herbicides. These additional requirements for a TDA Ag 3A license below are to remind school districts of their requirements.

  • Employed by a political subdivision, cemetery or government-owned golf course;
  • Hold a TDA commercial, noncommercial or Noncommercial Political Subdivision license;
  • Comply with annual continuing education required by TDA.
  • Applicators who work for public or municipal golf course and apply pesticides on turf, trees or shrubs can license with either program, Structural or Ag.
    • A person may not purchase or use a restricted-use or state-limited-use pesticide or regulated herbicides unless the person is:
      • licensed as a commercial, noncommercial or noncommercial political subdivision applicator in the use categories covering the proposed pesticide use; or
      • An individual acting under the direct supervision of a licensed applicator.

The Structural Pest Control Act (Chapter 1951 of the Occupations Code) requires licensing of businesses and individuals that perform structural pest control for hire. Additionally, employees of units of state government who apply pesticides as part of their job duties, and persons performing pest control at an apartment building, day-care center, hospital, nursing home, hotel, motel, or lodge, warehouse, food-processing establishment (other than a restaurant, retail food, or food service establishment), or school must be licensed. Structural pest control includes but is not limited to pests that may infest parks, buildings or structures and adjacent areas, industrial plants, streets, docks, railroad cars, trucks, ships or airplanes.

Structural pest control includes the following activities for compensation:

  • identifying infestations,
  • making inspection reports,
  • providing recommendations,
  • submitting estimates or bids,
  • contracting,
  • performing services to prevent, control or eliminate infestations, or
  • advertising such services.
