Licence types

The department's pesticide license program page describes commercial applicators as individuals who apply pesticides by contract or for hire. Public utility applicators and government applicators meet the same standards. Non-commercial applicators apply restricted-use pesticides on land owned or leased by an employer and are classified into one of the commercial categories. An operator is an employee of a licensed applicator without an applicator license. An operator may not apply pesticides more than 100 miles from the licensed applicator's physical location, and qualifies by passing a department exam at 80% or better, attending a department training course, or receiving training from a certified applicator. Operator licenses are renewed every calendar year. Renewals postmarked after March 1 add US$25, and federal or tribal agency applicants pay no license fees.

The category that covers trees and turf

On its commercial applicators page the department lists classification (3) Ornamental and Turf Pest Control as any applicator using or supervising pesticides to control pests in the maintenance and production of ornamental trees, shrubs, flowers and turf. Other classifications include (2) Forest Pest Control and (6) Right-of-Way, Rangeland, Pasture and Noncrop Pest Control. Core certification is required of every applicator and dealer, using the National Pesticide Applicator Certification Core Manual and the Montana laws and regulations booklet.

Getting the licence

The same page says the steps are to pass the core exam and the category-specific sections at 80% or better, meet the liability insurance requirement, complete an application and pay the fee of US$85 plus any operator fees. The department's training page says it offers free pesticide applicator examinations, proctored at its seven field offices, and a self-paced initial core training at US$50 that includes the national core manual. Applicators must keep application records for two years, including a note when no pesticide was used in a period.

Recertification

The department's training and recertification page says commercial applicators must earn 12 credits every four years per category, with six of the credits from in-person training, and private applicators 6 credits every 5 years. Categories (5) Aquatic, (2) Forest, (9) Non-Soil Fumigation, (3) Ornamental and Turf and others expire at the end of 2026. Fall in-person recertification trainings cost US$30 each and run in Billings, Belgrade, Kalispell, Missoula, Great Falls and Helena between October 14 and December 8, 2026. The department approves every training for credit regardless of sponsor, with over 400 approved a year. A free webinar on November 18, 2026 about vole control carries one credit in category 3.

Insurance

Commercial applicators, except seed treatment applicators and vertebrate pest applicators using only ground-applied baits, must meet financial liability requirements, and the page says this can be done only through liability insurance. Minimum limits are US$50,000 for an aerial applicator and US$30,000 for all others, kept in force through the whole licensing period. Proof of current insurance must be given to the department on request, and a license holder without current insurance is noncompliant. The department posts a certificate of insurance form and points to Administrative Rules of Montana 4.10.101 through 4.10.104 for exemptions.

Reciprocity

On the department's reciprocity page, people with an applicator or dealer license with like categories in another state can be licensed in Montana without the full exam series, but people moving to Montana are not eligible. The applicant passes the Montana out-of-state exam on the Pesticides Act and rules, proctored by their home state regulator or university extension, files service of process with the Montana Secretary of State with a US$5 filing fee, has the home state send a letter of good standing, and submits a copy of the current license and the out-of-state application with fees. Reciprocal licenses renew annually with an updated resident license and a new letter of good standing.
