Wyoming Pest Control License Requirements (2026)

Gabriel Giner

By Gabriel Giner, Editor  ·  Reviewed 2026-07-28  ·  CLR Editorial Review Desk

Most states split structural pest control into two credentials: a business/company license to operate for hire and at least one certified commercial pesticide applicator the firm must employ. Wyoming is an applicator-only state — it does not issue a separate pest-control business or company license or registration. The state credentials only the individual, and the Wyoming Environmental Pesticide Control Act of 1973 requires that every pesticide application made for hire be under the direct supervision of a certified commercial applicator (W.S. 35-7-376(b)). The regulator is the Wyoming Department of Agriculture (WDA), Technical Services Division — Pesticide Program, which issues the Commercial Applicator License (W.S. 35-7-355); the Board of Certification sets the competency and certification standards (W.S. 35-7-353). This is a pesticide/structural-pest credential, not a construction-contractor license — no contractor board and no NASCLA credential is involved. Competency is established solely by written examination: a Core/General Standards exam (Cat. 900) plus a written exam in each category sought, each passed at 70%. Structural work falls under Category 907 subcategories, wood-destroying pests and decay organisms under 907J, and fumigation under Category 909. There is no experience, age, residency, or (for residents) insurance prerequisite, and the license fee is $25 covering all qualified categories.

Governing Authority

This license is issued and enforced by Wyoming Department of Agriculture, Technical Services Division — Pesticide Program (Board of Certification, Wyoming Environmental Pesticide Control Act of 1973) (WDA) pursuant to Wyoming Environmental Pesticide Control Act of 1973, W.S. 35-7-350 through 35-7-376; Rules Ch. 28 (Applicator Certification Rules & Regulations). State agency that licenses and certifies commercial pesticide applicators (including structural pest control) under the Wyoming Environmental Pesticide Control Act of 1973. The Department issues the Commercial Applicator License (W.S. 35-7-355); the Board of Certification establishes certification standards and competency requirements and adopts the applicator rules (W.S. 35-7-353).

Eligibility Requirements

An applicant qualifies only after meeting the age floor of 0 and producing a valid Social Security Number. No Wyoming residency requirement. Nonresidents may be licensed (by exam or reciprocity) but must appoint the WDA director as their agent for service of process (W.S. 35-7-360(d)).

Good moral character

Not required by statute or rule.

Background investigation

None required. No criminal-history or fingerprint check appears in the Act or Chapter 28 rules; a falsified application or a prior pesticide violation can be grounds to refuse a reciprocal license (W.S. 35-7-359(c)).

Disqualifying conditions

  • Prior violation related to pesticides in Wyoming or another state (basis to refuse a reciprocal license, W.S. 35-7-359(c))
  • Falsified or incomplete application (W.S. 35-7-359(c))

Experience & Education Matrix

No fixed number of years of experience is set out in the cited sources for this credential; instead, the controlling requirement is No experience, apprenticeship, or education prerequisite to sit for the commercial applicator exam. Competency is established solely by written examination (Ch. 28 Sec. 5-6). An applicant who fails the same exam on two successive attempts must attend a WDA-approved new-applicator training program before a third attempt (Ch. 28 Sec. 6(i))..

Education substitution

Not applicable — there is no experience requirement to substitute for.

Examination Structure

Rather than a written state examination, the cited materials route this credential through: Wyoming Department of Agriculture (exams developed under Board of Certification standards; administered and proctored by WDA at its Cheyenne office or by a designated proctor). Training support is available through the University of Wyoming Extension Pesticide Safety Education Program.

Examination fee: None stated separately (no exam fee found; the $25 license fee is paid after passing)

Retake policy: Re-examination is limited to the category failed (Ch. 28 Sec. 6(h)). After two successive failures of an exam, the applicant must complete a WDA-approved new-applicator training program before a third attempt (Sec. 6(i)). Results are provided in writing within 30 days (Sec. 6(g)).

Insurance & Financial Security

Financial responsibility for a structural pest control business runs through pesticide (environmental) liability insurance rather than the surety bond a construction contractor posts; some states additionally require a bond for termite or subterranean work. The requirement that applies in this jurisdiction is set out below.

General liability

No liability-insurance minimum applies to resident commercial applicators. A nonresident commercial applicator seeking a reciprocal license must submit financial security or proof of liability insurance under W.S. 35-7-362, but no dollar minimum is specified in the statute or Chapter 28 rules — the amount is unconfirmed; confirm the current requirement with WDA before filing.

Workers' compensation

Unconfirmed. Workers' compensation is not addressed in the pesticide statute or Chapter 28 rules; general Wyoming employment law may apply. Verify separately.

Additional financial requirements

Not required for resident applicators.

Application and License Fees

Fee Amount
Application (non-refundable)$25
Initial license — sole owner$25
Initial license — non-sole ownerNo separate state fee
Renewal (every 3 years)$25

Maintenance & Renewal

Expect to renew the Pesticide Commercial Applicator License (certified commercial applicator, structural categories 907/909) every 3 years. Renewal currently costs $25. The $25 fee covers recertification/renewal for all qualified categories. A commercial applicator must notify WDA of any change of address or employment within 30 days (W.S. 35-7-359(b)) and any change of business address within 7 days (Ch. 28 Sec. 15(a)).

Continuing education: Recertify each cycle by one of three routes (Ch. 28 Sec. 6(k)): (1) accumulate 24 hours of WDA-approved training during the license's valid years; (2) attend the annual recertification short course; or (3) re-examine in all applicable categories. The license is issued for the portion of the calendar year of issue plus 25 months and expires January 31 of the third year (Sec. 6(j)) — a roughly three-year cycle.

Reciprocity and Endorsement

There is no contractor-style NASCLA reciprocity for pest control; any recognition runs through commercial-applicator certification agreements, and Wyoming's position is set out below.

Reciprocal State Accepted Exam Conditions
No formal bilateral reciprocity agreements identified.

Wyoming offers reciprocal licensing for out-of-state certified commercial applicators. Under W.S. 35-7-362 (the controlling reciprocity section) and Ch. 28 Sec. 6(n), the director may license without re-examination a nonresident who is licensed or certified in another state substantially in accordance with the Act, provided the applicant presents their applicator license and a letter of verification — but reciprocity is extended ONLY to applicants from states that accept Wyoming certification in return. Nonresident commercial applicators must also submit financial security or proof of liability insurance and appoint the WDA director as agent for service of process (W.S. 35-7-360(d)). WDA provides a Reciprocal Pesticide Applicator Application Packet and a Letter of Good Standing request form. NASCLA does not apply — it is a construction-contractor credential, not a pest-control certification.

Pest Control Licensing in Neighboring States

Contractors working near a state line, or weighing where to qualify first, should compare Wyoming's requirements against the bordering jurisdictions before committing to an application:

Step-by-Step Application Roadmap

  1. Identify the categories you will apply pesticides in. Determine which written category exams you must pass. Structural applicators take Cat. 907G (Structural – General); wood-destroying pests and decay organisms require Cat. 907J; fumigation requires Cat. 909. Every applicant must also pass the Core/General Standards exam (Cat. 900).
  2. Study the Core and category materials. Prepare using WDA and University of Wyoming Extension Pesticide Safety Education Program study materials for the Core (General Standards) and each category sought. No experience or training hours are required before testing, though a form footnote indicates certain categories may require prior WDA approval — confirm with WDA.
  3. Schedule and pass the Core plus each category exam at 70%. Contact the WDA Pesticide Program to schedule testing at the Cheyenne office (or with a designated proctor). Pass the Core/General Standards exam and each relevant category or subcategory exam at a minimum score of 70% (Ch. 28 Sec. 6(f)). Results are provided within 30 days.
  4. Submit the Commercial Applicator License application and $25 fee. File the Commercial Applicator License Application (WDA-66A) with the $25 fee. The single fee covers all categories you have qualified for, with no per-category charge. Government-entity employee applicators are fee-exempt (Ch. 28 Sec. 6(d)).
  5. Confirm supervision structure — no separate business license exists. Because Wyoming issues no pest-control business or company license, ensure every application made for hire is performed by, or under the direct supervision of, a certified commercial applicator (W.S. 35-7-376(b)). Non-certified 'competent persons' may apply only under that direct supervision.
  6. Nonresidents: add reciprocity and service-of-process steps. A nonresident should pursue reciprocity under W.S. 35-7-362 (license plus letter of verification), submit financial security or proof of liability insurance, and appoint the WDA director as agent for service of process (W.S. 35-7-360(d)) using the Reciprocal Pesticide Applicator Application Packet.
  7. Maintain certification through the recertification cycle. Recertify each roughly three-year cycle by accumulating 24 hours of WDA-approved training, attending the annual recertification short course, or re-examining in all applicable categories, and pay the $25 recertification fee before the January 31 expiration (Ch. 28 Sec. 6(j)-(k)).

Pre-Submission Checklist

The most critical documents or confirmations the applicant should have in hand before filing with WDA:

Study and Reference Materials

These are the preparation and reference materials tied to this credential — cited by the regulator or widely used by applicants. CLR earns nothing from listing them.

  • Core / General Standards study materials (Cat. 900) and structural category manuals (Cat. 907/909) — Wyoming Department of Agriculture, Pesticide Program. Basis for the Core exam and each category/subcategory exam; every exam requires a minimum 70% score. Category numbering on the 5/2025 application form (907G/H/I/J structural, 909 fumigation) differs from the Chapter 28 rules numbering — use the current form categories and confirm with WDA.
  • Pesticide Safety Education Program training and recertification short course — University of Wyoming Extension. Provides training support for initial certification and satisfies recertification through approved training hours or the annual short course.
  • Commercial Applicator License Application (WDA-66A, 5/2025) — Wyoming Department of Agriculture. Lists the operative categories (907G/H/I/J structural, 909 fumigation, 916, 917) and confirms the $25 fee and the 25-month/January-31 license term.

Common Filing Mistakes

Based on the board's own instructions and the sources cited here, the problems below are what most often stall a Wyoming Pest Control application.

Assuming Wyoming issues a pest-control business license

Wyoming has no separate pest-control business or company license. Firms that budget or wait for a nonexistent company license miss the real requirement: employing or designating a certified commercial applicator and ensuring all for-hire applications occur under that applicator's direct supervision (W.S. 35-7-376(b)).

Performing termite/WDO or fumigation work without the specific category

The Core exam and a general structural category do not authorize wood-destroying-organism work (Cat. 907J) or fumigation (Cat. 909). Each is a separate exam passed at 70%, and fumigation may carry additional WDA training/approval per a form footnote — performing that work without the category is a violation.

Letting the certification lapse past the January 31 expiration

The license expires January 31 of the third year. Failing to complete 24 approved training hours, the annual short course, or re-examination and to pay the $25 recertification fee before then leaves the applicator uncertified, which halts all for-hire application authority.

Non-certified personnel applying pesticides without direct supervision

Wyoming defines no formal registered-technician license tier. Non-certified 'competent persons' may apply pesticides only under the direct supervision of a certified commercial applicator; allowing them to apply independently violates W.S. 35-7-376(b).

Nonresidents overlooking the reciprocity and service-of-process conditions

Reciprocity under W.S. 35-7-362 is extended only to applicants from states that accept Wyoming certification in return, and nonresident applicators must submit financial security or proof of liability insurance and appoint the WDA director as agent for service of process (W.S. 35-7-360(d)).

Frequently Asked Questions

Do I need a license to do pest control in Wyoming?

Yes. Any person who applies pesticides for hire must be a certified commercial applicator, or must work under the direct supervision of one (W.S. 35-7-376(b)). The Wyoming Department of Agriculture issues the Commercial Applicator License after the applicant passes the Core/General Standards exam plus each relevant category exam at 70% and pays the $25 fee. Applying structural pesticides for hire without that certification or supervision is unlawful.

Does Wyoming require a separate pest-control business license in addition to the applicator certification?

No. Wyoming has no separate pest-control business or company license or registration — this is the key structural difference from most states. The state credentials only the individual commercial applicator. A firm operates lawfully by ensuring every application for hire is made by, or under the direct supervision of, a certified commercial applicator it employs or designates. The business-versus-applicator distinction collapses into a single individual credential here.

How is termite and wood-destroying-organism work licensed in Wyoming?

Wood-destroying pests and decay organisms are handled under Category 907J (Structural – Wood Destroying Pests & Decay Organisms), a separate exam-based subcategory passed at 70%; related Category 916 covers Wood Preservatives & Wood Treatment. No separate WDO/termite inspection-report certification or dedicated errors-and-omissions insurance requirement was found in the Act or Chapter 28 rules. An applicator must hold the specific category to perform that work.

What does fumigation certification require in Wyoming?

Fumigation is a separate category exam — Category 909 (Fumigation, Soil and Non-Soil) on the current 5/2025 application form — passed at 70%. The application form carries a footnote stating certain categories require specialized training and prior WDA approval, but Chapter 28 expressly imposes separate/prior training only on the M-44/Sodium Cyanide and Livestock Protection Collar predator-control subcategories; whether the footnote applies to fumigation is unconfirmed. Verify current fumigation training requirements directly with WDA before applying.

How often must a Wyoming commercial applicator recertify?

Licenses are issued for the portion of the calendar year of issue plus 25 months and expire January 31 of the third year — a roughly three-year cycle (Ch. 28 Sec. 6(j)). Recertify by accumulating 24 hours of WDA-approved training during the valid years, attending the annual recertification short course, or re-examining in all applicable categories (Sec. 6(k)), and pay the $25 recertification fee. Applicators must also report address or employment changes within the required 7 to 30 days.
