Minnesota pest control license: structural pest control applicator and company licenses
What license do you need to do pest control in Minnesota?
A structural pest control applicator license from the Minnesota Department of Agriculture. MDA issues the license in two grades: journeyman, the entry credential that requires passing the Core and Journeyman exams, and master, which adds two years of licensed journeyman experience. A fumigation endorsement can be added to either grade. A company performing structural pest control for hire needs a separate company license and must employ at least one licensed master.
Minnesota does not fold structural pest control into its general commercial applicator program. It runs it as its own license type under Chapter 18B, administered by the Minnesota Department of Agriculture, with two individual grades that govern who may work and who may supervise: journeyman and master. A company performing the work for hire holds a separate company license and must keep at least one licensed master on staff. The fumigation endorsement sits on top of either grade rather than standing alone. If you want the federal layer underneath, the national pesticide applicator license hub owns and sources the EPA rules; come back here for what Minnesota adds.
Who is telling you this, and why: Fieldwynn is a field-service app for small pest-control crews, we are building it, and it has not launched. The next step at the foot of this page is an early-access email ask, not a purchase. Read the page as a funnel rather than a disinterested verdict. Every Minnesota figure below is quoted from an MDA or Revisor of Statutes page and linked back to it, which is the part that holds whoever ends up running your route.
The two grades: journeyman and master
MDA defines structural pest control applicator licenses as covering applicators that apply pesticides in, on, under, or around structures. The license comes in two grades, and the difference between them is supervisory authority plus experience.
- Journeyman. The entry credential. An applicant passes two closed-book exams, Core (A) and the SPCA Journeyman, and works as an employee of, or under the direction of, a licensed master. Every journeyman must be employed by a licensed structural pest control company with a Master applicator.
- Master. The supervisory credential. An applicant must have at least two years of direct experience as a licensed journeyman, either in Minnesota or in a state with equivalent certification requirements, and pass a closed-book test administered by the commissioner. MDA’s requirements page confirms the two-year journeyman prerequisite. The master is the grade that lets you sign for a company: a sole proprietorship, company, partnership, or corporation performing structural pest control for hire must be or employ a licensed master.
A fumigation endorsement can be added to either grade by passing an additional exam. The endorsement covers fumigants in stored grain and structures and corresponds to category N (Non-Soil Fumigation) on MDA’s license-types page.
That two-grade structure is where Minnesota differs from the other states this site covers. Florida, for comparison, certifies an operator in charge by category rather than by grade, and licenses the business per location; California splits structural and outdoor pest work across two agencies entirely; Georgia licenses structural work through a commission. Illinois splits pest control between two agencies: IDPH licenses structural work inside and around buildings while IDOA licenses outdoor and for-hire pesticide application, so a company doing both needs credentials from both. For any other state, look up the pest control regulator directly rather than assuming Minnesota’s grades apply elsewhere.
The company license
A structural pest control company license is separate from the individual applicator license. The company must employ at least one licensed Master applicator and carry workers’ compensation insurance. Minnesota Statutes 18B.32 bars a company from performing structural pest control applications unless it is or employs a licensed master: if the master departs, the statute does not provide a grace period, and the company may not continue structural work until another master is on staff. MDA strongly encourages new applicators to apply online before the testing appointment; the structural pest control company license application is available as a printed form.
What MDA publishes it costs
Minnesota publishes real numbers, so this page quotes them, each tied to the MDA page that states it.
| MDA fee | Total | Breakdown and timing |
|---|---|---|
| Structural pest control applicator (initial or annual renewal) | $55 | $50 license fee + $5 MDA processing fee; late fee of $25 applied after January 1 |
| Structural pest control company (initial or annual renewal) | $295 | $200 license fee + $85 ACRRA surcharge + $10 MDA processing fee; late fee of $100 applied after January 1 |
| Retest: Master or Journeyman exam | $250 | Charged when an applicator retests instead of attending an MDA-approved recertification workshop |
| Retest: Fumigation exam | $150 | Same trigger as above, for the fumigation endorsement |
The company fee includes an $85 Agricultural Chemical Response Reimbursement Account (ACRRA) surcharge; the individual applicator fee does not carry the ACRRA surcharge. The statutory late-fee penalty is 50 percent of the application fee. MDA’s fee page publishes no separate initial exam fee; the only exam fees listed are the retest fees above.
Financial responsibility and insurance
MDA requires structural pest control applicators to meet financial responsibility requirements before licensing. The applicator (or the employer) can satisfy the requirement in any one of three ways: net assets of at least $50,000 available for judgments, a certificate of liability insurance, or a performance or surety bond.
If the path is insurance, the published minimums for structural pest control are $100,000 for bodily injury, $200,000 for bodily injury or death of two or more per occurrence, and $10,000 for property damage per occurrence. The certificate must name the Minnesota Department of Agriculture as certificate holder. A deductible of up to $500 is allowed. If the employer carries the required coverage, licensed employee applicators do not need their own. The pest control business insurance guide covers the coverages a pest business carries and the statutory minimums other states set.
Renewal, recertification and the three-month cutoff
Every structural pest control license expires on December 31. Renewal forms are mailed to the employer in November, and applicators must meet recertification requirements every year before renewal. The structural pest control category runs on a one-year recertification cycle: attend an MDA-approved recertification workshop, or retest at the fees listed above.
The lapse rule is the line worth knowing. A license not renewed within three months of expiration must be reobtained as an initial license, subject to initial requirements and fees. That means if you let the license sit past March 31, you are not paying a late fee; you are retaking the exams and starting from the beginning.
Where the paperwork ends and the label begins
This page has covered who may perform structural pest control for hire in Minnesota, at which grade, at what cost, and on which renewal clock. It has said nothing about what goes in a tank. That boundary is deliberate: the product label carries the force of law, and what you apply, at what rate, and with what handling and re-entry precautions is set by that label and by the training behind your certification. Study materials may be ordered from University of Minnesota Bookstores Extension Publications, and the exam is scheduled by contacting an MDA testing location.
What sits on our side of that line is arithmetic and record-keeping. The pesticide application log is a structured place to write down what was applied; the restricted-entry interval timer turns an REI you read off the label into a clock time; and the pest control pricing calculator works out what to charge per job once the license is in hand.
When you are ready to run the licensed route, Fieldwynn is the field-service app we are building to carry the scheduling, certificate of insurance tracking, and renewal-date reminders for a small crew. It has not launched, so the next step below is an early-access email ask, and the calculators and the licensing facts stay free either way.
