This page reports what the official source says. It is not legal advice: ask the office named here. The source is the Illinois Department of Agriculture, which certifies and licenses people who apply pesticides outdoors and in producing farm products. The same page says the Illinois Department of Public Health handles pesticide use in and on man-made structures. The parent page, pesticide licences by country, has the national background.

Who needs a license
The department's page on pesticide certification and licensing says a license is required of everyone applying restricted use pesticides, and of anyone applying restricted or general use pesticides in the course of employment. A person applying a general use pesticide on their own property is exempt. A license is required to buy restricted use pesticides but not general use ones.
Applicator and operator
The page defines an applicator as the person in an organization responsible for all pesticide purchasing, storage, handling and use, usually an owner, supervisor or foreman. Each organization needs at least one licensed applicator at each facility location, and the categories on the applicator's license set the areas where the company may legally apply. An operator is employed and supervised by a licensed applicator. The commercial not-for-hire licenses cover employees who apply only on their employer's property, at US$180 for an applicator and US$150 for an operator, each for three years, and need no certificate of insurance.
Categories and exams
The department lists 17 categories: aquatic, demonstration and research, field crop, forest, fruit, grain facility, livestock, mosquito, ornamental, plant management, regulatory, right-of-way, sewer line root control, seed treatment, soil fumigation, turf and vegetable crop. Ornamental is described as pesticide use on trees, shrubs and ornamental plantings. Turf is described as pesticide use on turf areas and sod farms. The page says a company's whole range of pesticide use has to be covered by the categories on the applicator's license.
An applicant passes the 100-question General Standards exam with 70 or more, plus one or more 50-question category exams with 35 or more correct. Operators pass General Standards only. The department's training and testing page says it offers in-person exams with pre-registration and online exams through a proctoring service, which charges a small fee at sign-up. The University of Illinois Pesticide Safety Education Program gives workshops for general standards, turfgrass, rights-of-way, mosquito and ornamental, with free testing after each in-person workshop, plus online courses open for 30 calendar days and printed manuals.
Fees and renewal
| License | Fee for three years |
|---|---|
| Commercial applicator | US$300 |
| Commercial operator | US$240 |
| Commercial not-for-hire applicator | US$180 |
| Commercial not-for-hire operator | US$150 |
| Pesticide dealer | US$360 |
The licenses run three years, and the page says the exams are valid for three years if the license does not lapse. The page read does not list continuing education credits.
Insurance
A commercial applicator shows financial responsibility at first licensing and at each renewal, as a surety bond or a certificate of liability insurance. The certificate carries a 30-day cancellation notice and coverage of at least US$50,000 per person and US$100,000 per occurrence for bodily injury, with an annual aggregate of at least US$500,000, and US$50,000 per occurrence for property damage with an annual aggregate of at least US$50,000. A combined single limit of US$100,000 with a US$500,000 aggregate is allowed instead. Every company location is listed on the policy.
Reciprocity
The page says a person licensed in the same type of application in their state of residence, through a closed-book exam in the previous three years, can qualify for a one-calendar-year Illinois license. It is two steps: the home state completes a verification form and sends it to Illinois, and the applicant sends the reciprocal application and fee.
