To apply restricted-use pesticides in Kansas, you need a Kansas pesticide license issued by the Kansas Department of Agriculture, and the specific credential depends on your work: a private applicator certification if you treat your own agricultural land, a commercial applicator certificate if you apply pesticides on someone else’s property, or a registered pest control technician designation if you work under a certified commercial applicator. Each has its own age rule, exam, fee, and renewal cycle. Working without the right credential can bring civil penalties of up to $5,000 per violation.1Legal Information Institute. Kansas Administrative Regulations 4-13-62 – Amount of Civil Penalty
Which Credential You Need
Private Applicator
A certified private applicator uses restricted-use pesticides to produce agricultural commodities on land they own or rent, or on their employer’s agricultural property. Kansas also allows a private applicator to treat another producer’s land without compensation, other than a trade of personal services between the two producers.2Kansas Office of Revisor of Statutes. Kansas Code 2-2438a – Definitions The certificate lasts five years, expiring on your birthday in the fifth calendar year after the year of issue.3Kansas Office of Revisor of Statutes. Kansas Code 2-2445a – Certified Private Applicators Certificate Restrictions Qualifications Examination Fees Reciprocity of Certificates
Commercial Applicator
A commercial applicator applies restricted-use pesticides on property other than their own or for purposes beyond agricultural commodity production. This is the credential for professional pest control, lawn care, and any service that treats someone else’s property. Commercial certificates expire at the end of the second calendar year after the year of issue, giving you roughly a three-year window before renewal.4Kansas Department of Agriculture.

Registered Pest Control Technician
A registered pest control technician is an uncertified worker who applies pesticides under the supervision of a certified commercial applicator. The designation is limited to wood-destroying, structural, ornamental, turf, or interior landscape pest control, or a combination of these. Technicians must complete verifiable training set by the Secretary of Agriculture, and their registration expires at the end of each calendar year.5Kansas Office of Revisor of Statutes. Kansas Code 2-2440b – Pest Control Technician Registration Requirements and Fees Unlawful Acts
Kansas law allows uncertified employees of a licensed pesticide business to apply pesticides under the instructions and control of a certified applicator who is available when needed, even if the certified applicator is not physically at the site.6Kansas Secretary of State. 2024 Session Laws of Kansas Chapter 55 House Bill 2607 The supervising applicator remains legally responsible for the work.
Commercial Categories
Commercial certification is not a single credential. You pass a general exam and then one or more category exams tied to the actual work you do. Picking the wrong category leaves you uncertified for that work. The categories most people encounter include:
- Category 1A, Agricultural Plant Pest Control
- Category 2, Forest Pest Control
- Category 3A, Ornamental Pest Control
- Category 3B, Turf Pest Control
- Category 5, Aquatic Pest Control
- Category 6, Right-of-Way Pest Control
- Category 7A, Wood-Destroying Pest Control
- Category 7E, Structural Pest Control
Kansas recognizes more than 20 categories and subcategories in total, including agricultural animal pests (1B), wildlife damage (1C), seed treatment (4), industrial weed control (7C), health-related pest control (7D), public health pests (8), and noxious weeds (9A).7Legal Information Institute. Kansas Administrative Regulations 4-13-3 – Categories and Subcategories of Qualification for the Licensing of Pesticide Businesses and Certification of Commercial Applicators
Age, Study Materials, and the Exam
You must be at least 18 to earn either a commercial or private applicator certification.8Legal Information Institute. Kansas Administrative Regulations 4-13-12 – Age Restriction for Certification One narrow exception: an uncertified person as young as 16 can apply restricted-use pesticides if directly supervised by a family member who holds a private applicator certification, and the work is on land owned or leased by the applicator or their family.3Kansas Office of Revisor of Statutes. Kansas Code 2-2445a – Certified Private Applicators Certificate Restrictions Qualifications Examination Fees Reciprocity of Certificates
Study materials come from the Kansas State University Research and Extension Pesticide Safety program. Each category has its own manual, available as a free PDF download or as a printed copy through the K-State Research and Extension Bookstore.9K-State Extension. Commercial Pesticide Applicator Education Every commercial applicator also studies the General Manual, which covers label interpretation, safety equipment, environmental protection, and legal responsibilities.
Initial certification requires a written exam. Commercial applicants must pass the general exam and at least one category or subcategory exam. Private applicants take a single exam covering practices relevant to their operation and their legal responsibilities.10Legal Information Institute. Kansas Administrative Regulations 4-13-14 – Private Applicator Examination The passing score is 75%. Each exam costs $45, and retakes cost the same. If you need multiple categories, you pay $45 for each. The KDA offers exams once a month in Garden City, Hays, Olathe, Topeka, and Wichita.11Kansas Department of Agriculture. Commercial Pesticide Applicator – Opportunities to Register for Tests Private applicator exams may also be given by Kansas State University Extension representatives.
Register for commercial exams through the KDA portal. Once you pass, submit your application and licensing fees. The private applicator certification fee is capped at $10, though an initial training or testing fee of up to $75 may apply starting July 1, 2028.3Kansas Office of Revisor of Statutes.

When You Also Need a Business License
Individual certification and a business license are separate requirements. If your company applies pesticides to another person’s property for compensation, the company needs a pesticide business license from the KDA, even if every applicator on staff is already certified. The business license renews annually and expires December 31.12Kansas Office of Revisor of Statutes. Kansas Code 2-2440 – Pesticide Business License Requirements and Fees Exemptions Unlawful Acts Government Agency Registration Exemptions License and Registration Renewals
The application fee is $140 per category in which the business applies pesticides, plus $15 for each uncertified employee who applies pesticides. Any uncertified worker employed for more than 10 days in a 30-day period, or for five consecutive days, must be reported to the KDA within 30 days and the additional fee paid then.12Kansas Office of Revisor of Statutes. Kansas Code 2-2440 – Pesticide Business License Requirements and Fees Exemptions Unlawful Acts Government Agency Registration Exemptions License and Registration Renewals
Before the license can be issued, the business must file a certificate of liability insurance. Kansas law sets the minimum at $25,000 for bodily injury per occurrence and $5,000 for property damage per occurrence. If coverage lapses, the insurer must notify the KDA at least 10 days before cancellation, and the Secretary will suspend the business license until coverage is restored.13Kansas Legislature. Kansas Code 2-2448
Renewal and What Happens if You Lapse
The renewal timeline depends on the credential. Commercial applicator certificates expire at the end of the second calendar year after issue. Private applicator certificates last five years, expiring on your birthday in the fifth calendar year after issue.3Kansas Office of Revisor of Statutes. Kansas Code 2-2445a – Certified Private Applicators Certificate Restrictions Qualifications Examination Fees Reciprocity of Certificates Pest control technician registrations and business licenses both expire every December 31.12Kansas Office of Revisor of Statutes. Kansas Code 2-2440 – Pesticide Business License Requirements and Fees Exemptions Unlawful Acts Government Agency Registration Exemptions License and Registration Renewals
Commercial applicators can renew by retaking the exams or by earning continuing education credits at approved training sessions. Every applicator needs one core credit hour, plus category-specific hours ranging from three to seven. Category 1A (Agricultural Plant Pest Control) and Category 7A (Wood-Destroying Pest Control) each require seven credit hours; Category 1D (Stump Treatment) requires three. All credits must be earned by December 31 of the expiration year.14Kansas Department of Agriculture. Recertification Training Private applicators can also renew by attending approved recertification training instead of retesting.
Miss the deadline and the consequences are steep. If you fail to renew your commercial certification with the KDA within 30 days of expiration, you automatically forfeit every continuing education credit you earned during the certification period. At that point, exams are your only path back: the general exam plus every category exam, from scratch.4Kansas Department of Agriculture. Pesticide Applicator The same happens if you simply never accumulate enough training hours before the deadline. Put a calendar reminder well before your expiration year.
Penalties for Working Without or Misusing a License
Applying pesticides inconsistently with their label, improperly storing or discarding pesticides in a way that causes harm, or failing to comply with any other provision of the Kansas Pesticide Law are unlawful acts.15Kansas Office of Revisor of Statutes. Kansas Code 2-2453 – Unlawful Acts Civil penalties for misuse or improper storage run from $100 to $5,000 per violation. Other violations of the act that do not involve direct misuse carry penalties of $100 to $1,000 per violation.1Legal Information Institute. Kansas Administrative Regulations 4-13-62 – Amount of Civil Penalty Operating a pesticide business without a license, advertising pest control services without proper credentials, or employing uncertified workers outside the supervision rules can each trigger separate enforcement actions and additional fines.
