Wyoming Pesticide Supervision and Licensing Rules

Last scannedOct 19, 2026, 2:19 AM

In one sentence

This law requires certified applicators to supervise pesticide applications made for hire, allows reciprocal licensing for out-of-state applicators, and prevents local governments from creating stricter pesticide rules than the state.

What it does

  • Requires that all pesticide applications made for hire be under the direct supervision of a certified commercial applicator.
  • Requires that all applications of restricted use pesticides be under the direct supervision of a certified applicator.
  • Allows a certified applicator to be off-site if they are available within a reasonable time and distance, defined as a response time of no more than one hour and a distance of no more than 50 air miles.
  • Requires the certified applicator to be physically present on-site when the use of the pesticide poses a potentially serious hazard to people or the environment.
  • Allows the director of the Department of Agriculture to issue reciprocal licenses to non-residents who are licensed or certified in another state, without an examination, provided they submit financial security or proof of liability insurance.
  • Prohibits local political subdivisions from adopting or enforcing rules regarding pesticide storage, sale, distribution, notification of use, or use that are more stringent than state law.
  • Allows the Department of Agriculture to seek restitution from an applicator or their employer for fees or expenses incurred to remediate a violation.

Who it affects

  • Certified commercial applicators and their employers.
  • The Wyoming Department of Agriculture.
  • Local political subdivisions such as cities and counties.
  • Non-resident applicators seeking reciprocal licenses.

Limits and unknowns

  • The law does not specify the exact criteria the Department of Agriculture will use to determine reciprocity, only that they must establish them by rule and regulation.
  • The law does not define what constitutes a 'potentially serious hazard' requiring on-site presence, leaving that determination to the applicator's judgment based on the situation.
