RequiredMontana Department of Agriculture — Pesti…
MCA 80-8-203 makes it unlawful to engage in the business of applying pesticides for another without a pesticide applicator's license from the Montana Department of Agriculture. The statute sets a $75 application fee plus an annual $10 waste-pesticide fee, matching the department's listed $85 for new and renewed commercial licenses. Applicants must pass a written exam for each classification they apply in, and are not re-examined on renewal (MCA 80-8-206).
Employees who apply pesticides without their own license are licensed as operators under the applicator: they qualify by passing a department exam at 80%, attending department training, or being trained by a certified applicator, may not work more than 100 miles from the applicator's location, and renew each calendar year. The applicator is responsible for every operator's pesticide use.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Pesticide licensing is state-level (Department of Agriculture). Local governments may levy general business license fees; the state construction contractor preemption in MCA 37-45-204 does not apply because pest control is not construction.

Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
Montana licenses the applicator, not a structural pest control company; the commercial applicator license under MCA 80-8-203 is the credential.
Operators may not apply pesticides more than 100 miles from the licensed applicator's physical location.
Pest control is not construction work under MCA 37-45-102, so the Construction Contractor License does not apply to it.

Violating the Pesticides Act or its rules, or obstructing the department, is a misdemeanor.
Using pesticides without the required license, misuse causing exposure or harm, and record failures are major violations.
