Pest control is regulated by the Idaho State Department of Agriculture (ISDA) under the Idaho Pesticides and Chemigation Act, not by DOPL. Anyone who applies pesticides on another's land or property for compensation is a professional applicator (Idaho Code § 22-3401) and may not operate without an ISDA professional applicator license (§ 22-3404(3)): pass the Applicator Core Competency exam and each category exam with 70%, be at least 18, and show financial responsibility. Structural work falls in the Industrial, Institutional, and Structural Pest Control categories (non-commodity IP and commodity CP).
Financial responsibility is $50,000 per person / $100,000 per occurrence bodily injury and $50,000 property damage with a deductible of no more than $5,000 (IDAPA 02.03.03.100.05); a lapse automatically suspends the license. Effective July 1, 2026 the license fee is $300 and exams are $10 per category; licenses run five-year periods ending December 31, renewed with 40 recertification credits. Cities and counties may not adopt their own pesticide rules (§ 22-3426).
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Pesticide regulation is exclusively state: § 22-3426 prohibits any city, county, taxing district, or other subdivision from adopting pesticide rules on sale, use, application, notification, or applicator training and certification (fire code inspections excepted). Local governments add only general business licensing where they require it.
The local offices section below names the exact permit desk for every Idaho county on file.
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.
Idaho regulates pest control through ISDA's pesticide program; it is not a DOPL contractor registration or license.
If financial responsibility lapses, the license is automatically suspended until ISDA verifies compliance (§ 22-3404(3)(e)).
The professional applicator license is $300 and the commercial apprentice license $120 under IDAPA 02.03.03.280 as amended effective July 1, 2026.
