Iowa Code § 206.6 bars anyone from engaging in the business of applying pesticides to another's property without a commercial applicator license from the Iowa Department of Agriculture and Land Stewardship (IDALS) — a $25 annual license per location, expiring December 31. Every individual who applies must be certified (§ 206.5): $75 for a three-year certification earned by passing the core exam and the category exam, such as 7A General and Household Pest Control or 7B Termite.
For structural pest control, applicators must pass a written test, and IDALS renews a firm's license only if all its applying personnel are certified (§ 206.31). The firm must keep evidence of financial responsibility on file — $100,000 property damage and $100,000 public liability, or $100,000 per occurrence with a $300,000 aggregate (§ 206.13). Chapter 206 preempts local pesticide ordinances (§ 206.34).
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: Iowa Code § 206.34 preempts city and county ordinances relating to pesticide use, sale, distribution, storage, labeling, and registration. Pest control is not 'construction', so chapter 91C contractor registration does not ordinarily apply.
The local offices section below names the exact permit desk for every Iowa 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.
Every chapter 206 license expires December 31; renewals filed after January 1 owe a 25% delinquent fee unless you swear you didn't apply after expiration (§ 206.10).
Retest every third year, or attend two hours of continuing instruction per category each year (§ 206.5(2)(b)).
A new employee may apply for 21 days without certification while under the direct, in-sight-or-hearing supervision of a certified applicator (§ 206.5(3)).

Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
IDALS may assess civil penalties against a commercial applicator for violating chapter 206 or its rules, weighing willfulness, danger, cost, and compliance history.
Violating chapter 206 (other than a few listed sections) is a serious misdemeanor.
Inside city limits, the city office listed here issues the permit; the county office serves unincorporated areas. Every office links to its official page.
