A plain-English walkthrough of getting licensed in Minnesota — commercial, noncommercial, structural, and private paths, the Core and category exams, what it costs, and how to study and pass. Pesticide licensing in Minnesota is run by the Minnesota Department of Agriculture (MDA).
Licensing takes a passing score on the Core exam (Category A) plus at least one category exam — closed-book, monitored, at MDA-partnered testing locations statewide (aerial applicators add Category B). Apply and pay online first; proctors verify payment before testing. Structural pest control is its own license type, requiring employment with a licensed company under a Master applicator. Study materials come from the University of Minnesota Extension manual store — the same national core our practice bank drills.
Every applicator license expires December 31 and renews annually (license fee plus the ACRRA surcharge; renew before March 1 to dodge late fees). Recertification is Minnesota's twist: instead of counting CEUs, you attend an MDA-approved workshop on your category's 2-or-3-year cycle — starting the year after you first license. Miss your workshop window and there are no makeups: you retest to renew. Licenses are employer-bound, so changing companies means a new license (your scores carry). Private certification runs through the U of M Extension at about $100. Confirm current fees on MDA's fee schedule.
Minnesota skips CEU counting entirely: instead of tallying credits, you attend one MDA-approved recertification workshop for each category on your license (or retest for every category) before the recertify-by date printed on your license card. How often that comes up depends on the category — some recertify every year, many every two years, and a few every three — so the workshop cycle is category-specific, and holding several categories can mean different clocks. Licenses themselves expire December 31 and renew annually with the license fee plus the ACRRA surcharge; commercial and noncommercial holders may renew up to 12 months late, but renewing before March 1 avoids late fees (structural licenses get only three months). There are no makeups — miss your workshop window and you retest all categories to renew. Licenses are employer-bound, so moving companies means a new license before you can work. Confirm your attend-by dates on the MDA license lookup before your cycle ends.
Anyone applying any pesticide — including herbicides — for hire, meaning you charge or invoice for the service. Restricted-use application on your employer's own property takes the noncommercial license instead.
By workshop, not CEU-counting: attend an MDA-approved recertification workshop on your category's two- or three-year cycle, starting the year after you first license. All approved workshops include Core credit. Miss the window and you retest — workshops cannot be made up.
Every year — all applicator licenses expire December 31, with renewal forms mailed to your employer and a March 1 late-fee deadline. The workshop recertification cycle runs alongside the annual license renewal.
It becomes invalid — licenses are issued in your employer's name. You obtain a new license under the new employer, but your exam scores and workshop attendance stay credited to you.
