New Hampshire Commercial Applicator Exams for Structural Pest Control

New Hampshire certifies commercial pesticide applicators by Division-prepared examinations under Pes 304. Applicants take separate written exams for general principles, regulations, and each category sought. Operational certificates require 60 percent on written exams; supervisory certificates require 70 percent written plus a pass-fail oral board. Exam and re-exam fees are $15 per category under the NHDAMF schedule effective July 1, 2025. Reviewed rules require New Hampshire exams - no initial certification-by-reciprocity path was identified.

New Hampshire Examination Model: Operational, Supervisory, and Categories

New Hampshire does not use a single exam covering every pest control treatment. NHDAMF’s Division of Pesticide Control registers individuals through Pes 304 examinations, then ties those certificates to commercial for-hire firm registration under Pes 307. Passing exams alone does not authorize for-hire work - the firm must register before employee certificates issue, insurance must meet Pes 302.03 when applicable, and each for-hire business needs at least one supervisory-level certificate holder at the managerial level (Pes 403.01).

This page is an exam-path deep dive for owner-operators, career changers, and multi-state firms placing applicators in Manchester, Nashua, Concord, Portsmouth, and across the Lakes Region and North Country. It complements New Hampshire Phase 2 licensing pages by focusing on operational vs supervisory paths, F-series category exams, published fees, retake timing, and why out-of-state cards do not replace Division examinations on reviewed rules.

Cold-climate demand shapes category planning: F1 for general structural work; F3 for termite and other wood-destroying insects; F2 for mosquito/black fly programs; F4 only with real fumigation readiness; F8 for microbial services. Program-scale certified-individual counts are not published on sources reviewed for the facts pack. Fee tables rose effective July 1, 2025 - confirm current amounts on the NHDAMF Pesticide Licensing page before filing.

Pes 304 Written Exams: General, Regulations, and Category

Commercial applicants take separate written examinations under Pes 304:

  1. General - core pesticide principles (labels, safety, environment, equipment)
  2. Regulations - federal and New Hampshire pesticide law (RSA 430 framework and Pes rules)
  3. Category - operational or supervisory depth for each certification category sought

Supervisory category exams are deeper than operational exams (Pes 304.02(e)). Every registration applicant must pass Division-prepared examinations under Pes 302.02 and Pes 304 - reviewed rules do not waive the written battery for another state’s card.

Who sits which level. Operational applicants (Pes 303.02) must be 18+ and pass general, regulations, and category exams at the operational score. Supervisory applicants (Pes 303.01) must meet experience/education qualifications, submit the Commercial Resume Form - Supervisory Level Exam Requirement, pass supervisory written exams, then complete the oral board. Soft-confirm current form names on NHDAMF Applications materials.

Firm sequencing. Under Pes 307.02(c), the for-hire firm registers before individual applicator certificates issue to employees. Align exam scheduling with firm registration, Division-named insurance certificates, and the 30-day post-exam window in Pes 302.04.

Operational vs Supervisory Exam Paths and Pass Scores

New Hampshire’s dual certificate model is the core exam-planning decision for structural firms.

Operational Level Certificate. For commercial applicators under the crew structure: age 18+ (Pes 303.02) and 60 percent on general, regulations, and category operational written exams (Pes 304.08). At least one operational or supervisory registrant must be present on each commercial application crew (Pes 403.02) - uncertified helpers alone do not satisfy that rule.

Supervisory Level Certificate. At least one managerial employee per for-hire business must hold a supervisory certificate (Pes 403.01). Applicants qualify under Pes 303.01, pass supervisory written exams at 70 percent, pass the oral examination (Pes 304.04), and complete registration within 30 days of the last passed exam (Pes 302.04). Confirm Pes 303.01 pathway details on the live rule text before assuming a founder is immediately eligible - many new owners need operational time first.

Oral examination. Typical for-hire supervisory applicants must pass a pass-fail oral board after written exams (Pes 304.04), with limited exemptions in Pes 304.05 for certain commercial not-for-hire situations. Soft-confirm panel scheduling with the Division after applications are accepted.

After failure. Failed exams cannot be retaken sooner than 15 days; after three failures, wait six months, complete documented training, and submit proof before additional retakes (Pes 304.08(c)). Re-exam fees match the published per-category exam fee. Plan launch dates around retake and oral buffers.

Structural Category Examinations F1 - F4 and F8

Category exams must match the services you advertise. Official names and scopes follow Pes 302.01:

F1 - Industrial, Institutional, Structural, and Health Related Pest Control. Pesticides primarily for insect control in, on, or around structures and adjacent areas, and for protection of stored, processed, or manufactured products - the default for most residential and light commercial general-pest routes.

F2 - Mosquito and Black Fly. Mosquitoes, black flies, and other biting arthropods - relevant for seasonal Seacoast and Lakes Region programs when labeled and operationally appropriate.

F3 - Termites and Other Wood-Destroying Insects. Preventive and remedial termite, ant, powder-post beetle, and related WDO work. Do not market F3 on an F1-only certificate.

F4 - Fumigation. Fumigant pesticides for insect control, including beehive fumigation. Add only after category passage and real equipment readiness.

F8 - Microbial Pest Control. Mold, fungi, bacteria, and related organisms in structures and industrial processing facilities - separate from F1 insect authority.

Each category carries its own exam fee and 12 recertification credits per five-year cycle under Pes 402.01 (max 48 total if certified in five or more categories). Batch-plan F1 plus F3 when termite sales are part of the launch menu.

Exam Fees, Scheduling, and Post-Exam Filing

Published fees (NHDAMF Pesticide Licensing page; increase effective July 1, 2025):

  • Commercial applicator exam - $15 per category (or commodity group as described on agency materials)
  • Commercial applicator re-examination - $15 per category (RSA 430:34 III as referenced in Pes 304.08)
  • Annual commercial applicator license - $60

A separate commercial for-hire firm registration fee was not published on the reviewed agency fee page - confirm that line item with the Division when budgeting.

Scheduling. Complete license and exam applications before the Division schedules exams. Soft-confirm current contacts and calendars on NHDAMF Pesticide Licensing and Applications pages. Do not assume walk-in testing or same-week oral panels.

Thirty-day completion. Finish registration within 30 days of your last passed exam (Pes 302.04), or request a Division extension for documented hardship.

Delinquent renewal. If a license or certificate is not renewed by June 1, examination is required again (Pes 401.01(d)). Every fifth year, commercial applicators document Division-approved CE or retake exams (Pes 402.01). Missing June 1 is an exam-path failure mode, not only a late fee problem.

Exam day. Bring identification and materials the Division specifies. Prepare New Hampshire-specific regulations content - neighbor-state notes that skip Pes rules leave candidates exposed on the regulations paper.

Study Materials and Preparation Strategy

Official study-manual lists are not exhaustively enumerated in the verified facts pack. Soft-confirm required texts with the Division before ordering. UNH Cooperative Extension commonly distributes applicator manuals and preparation courses - verify materials match your operational or supervisory level and category.

General and regulations. Treat labels, PPE, environmental considerations, equipment, and poisoning recognition as testable. Skim RSA 430 and Pes 300 - 400 so firm registration, supervision, insurance, renewal, and CE questions feel familiar. Multi-state technicians often fail regulations when they study only federal Core content.

Category focus. Match study to Pes 302.01 scope. F3 needs WDO biology and treatment concepts - not F2 mosquito content. F4 needs fumigant safety beyond route-truck habits. F1 remains the baseline for Manchester multifamily and Seacoast commercial general-pest work.

Supervisory oral. Expect supervision, label compliance, and New Hampshire operational judgment; orals may go beyond written scope (Pes 304.02(f)). Practice explaining crew coverage under Pes 403.02 and how category permissions limit what you sell.

CE vs exams. Division-approved seminars - including out-of-state seminars accepted for CE under Pes 402.01(t) - support recertification only. They do not replace initial Pes 304 examinations.

How Reciprocity Differs From the New Hampshire Exam Path

Reviewed Pes 302.02 and Pes 304 require Division-prepared examinations for registration. No rule section reviewed grants certification-by-reciprocity or exam waiver based on out-of-state licensure. There is no parallel exam-waiver application for routine structural for-hire entry.

What out-of-state credentials can help with.

  • Experience on the supervisory Resume Form may support Pes 303.01 eligibility evaluation - the Division decides; it is not automatic credit.
  • Seminars approved by other states’ lead agencies may count for CE under Pes 402.01(t) - not for initial exams.

Multi-state operational reality. Register the New Hampshire for-hire firm, place required insurance naming the Division as certificate holder, credential staff through New Hampshire exams, and do not treat Massachusetts, Maine, or Vermont cards as authority to apply pesticides for hire in New Hampshire. No official source reviewed authorizes for-hire commercial pesticide application before required firm and individual credentials are issued.

New Hampshire Commercial Applicator Exams for Structural Pest Control: common questions

What exams do I need for a New Hampshire commercial pest control applicator certificate?

Under Pes 304, commercial applicants take separate written examinations for general principles, regulations, and each category sought at operational or supervisory level. Supervisory applicants also pass a pass-fail oral board after written exams (Pes 304.04). Pass scores are 60% operational and 70% supervisory written (Pes 304.08).

What is the New Hampshire pest control exam pass score?

Operational Level written exams require 60 percent. Supervisory Level written exams require 70 percent. The supervisory oral examination is pass-fail under Pes 304.04.

How much do New Hampshire commercial pesticide applicator exams cost?

As published on the NHDAMF Pesticide Licensing page (fee increase effective July 1, 2025), commercial applicator exams are $15 per category and re-examinations are $15 per category. The annual commercial applicator license fee is $60. Confirm current amounts before filing.

What is the difference between operational and supervisory exams in New Hampshire?

Operational applicants (18+) pass general, regulations, and category written exams at 60%. Supervisory applicants must meet Pes 303.01 qualifications, pass supervisory-depth written exams at 70%, and pass an oral board. Every for-hire business needs at least one supervisory certificate holder at the managerial level (Pes 403.01).

Which New Hampshire category exam do I need for general home pest control?

Most structural general pest work for hire maps to F1 - Industrial, Institutional, Structural, and Health Related Pest Control under Pes 302.01(g)(1). Termite and other wood-destroying insect treatments require F3; fumigation requires F4; microbial services require F8.

Does New Hampshire offer exam reciprocity for out-of-state pest control licenses?

No initial certification reciprocity or exam-waiver pathway was identified in reviewed Pes 302.02 and Pes 304 rules. Out-of-state applicators must pass Division examinations. Pes 402.01(t) allows other states’ approved seminars to count for recertification credit only - not initial licensing.

How soon can I retake a failed New Hampshire pesticide exam?

Failed exams cannot be retaken sooner than 15 days. After three failures, Pes 304.08(c) requires a six-month wait, documented training, and proof of that training before additional retakes. Re-exam fees are $15 per category on the published schedule.

Do I need an oral exam for New Hampshire supervisory certification?

Yes, with limited exemptions in Pes 304.05 for certain commercial not-for-hire situations. Typical for-hire supervisory applicants must pass the oral board after written exams (Pes 304.04). Orals are pass-fail and scheduled when Division panel members are available.

Does passing New Hampshire applicator exams automatically register my pest control company?

No. Individual Certificates of Registration and Commercial Business Registration - For Hire (Pes 307) are separate. The firm must register before employee applicator certificates issue (Pes 307.02(c)), and for-hire firms need a supervisory certificate holder plus required insurance proof.

How long do I have to finish New Hampshire registration after passing exams?

Pes 302.04 requires completion of registration requirements within 30 days of the last passed examination, unless the Division grants an extension for documented hardship. Do not leave post-exam paperwork open-ended.

Can I use continuing education instead of exams for first-time New Hampshire certification?

No. Initial commercial registration requires Division examinations under Pes 302.02 and Pes 304. Continuing education under Pes 402.01 supports five-year recertification (or you may retake exams). Out-of-state CE seminars do not replace initial New Hampshire exams.
