New Hampshire Pest Control License Requirements 2026

To perform structural pest control for hire in New Hampshire, a firm does not obtain a separate business or company license — the state runs an applicator-only regime. The New Hampshire Department of Agriculture, Markets & Food, Division of Pesticide Control (NHDAMF), under rules set by the NH Pesticide Control Board, certifies the individuals who apply pesticides rather than issuing a company credential. In practice a pest control company operating for hire must (a) employ at least one Supervisory-level commercial applicator who supervises applications and countersigns operational work, (b) place at least one Operational-level licensee on each crew that applies pesticides, and (c) carry the Pes 302.03 for-hire pesticide liability insurance with the Division named as certificate holder. This is a pesticide/structural-pest credential issued under RSA 430 and the N.H. Code Admin. Rules Pes 100–1100 — not a construction-contractor license, and NASCLA does not apply. Structural work is split into F-categories, including F1 (industrial/institutional/structural/health-related), F3 (termites and other wood-destroying insects), and F4 (fumigation), each requiring its own category exam in addition to the general/core and regulations exams.

Disqualifying conditions

Required Experience and Education

The applicant must document and verify at least 3 years of The Operational (crew) level is entry-level: age 18, no prior experience, pass the written exams at 60%. Supervisory (decision-maker) eligibility requires a roughly five-year combination of education and practical experience under Pes 303.01 — for example, 3 years registered at the operational level; OR a relevant college degree (entomology, plant pathology, forestry, etc.) plus at least one growing season at operational level; OR a 2-year agricultural/technical program plus one year; OR at least one year of practical experience plus two additional growing seasons of education/experience.. Keep payroll, tax, project, or supervisor records to support the claim, as the board can request proof for any period within its lookback window.

Accepted proof of experience or eligibility

Operational-level registration history with the Division
College or technical transcripts or diploma
Supervisor countersignature on the application

Education substitution

A recognized college/university degree in a relevant field substitutes for most of the experience (leaving one growing season); a 2-year agricultural school or technical institute substitutes down to one year of operational experience (Pes 303.01).

Examination Requirements

Rather than a written state examination, the cited materials route this credential through: New Hampshire Department of Agriculture, Markets & Food, Division of Pesticide Control

Examination fee: $15 per category or commodity group (RSA 430:34)

Retake policy: The re-examination fee is $15 per category (RSA 430:34). As a recertification alternative, certified persons may retake the exams during the fifth year of each 5-year cycle in lieu of accruing credits (Pes 402.01(r)). Exam question counts and time limits are not confirmed on any official source.

Insurance and Financial Requirements

Structural pest control is insured through pesticide liability cover rather than the bond construction contractors file, and only certain states add a termite-work bond. The specific requirement that applies in this state follows.

General liability

Required for commercial applicators FOR HIRE (Pes 302.03). Ground application: bodily injury liability $50,000 each occurrence / $100,000 aggregate and property damage $50,000 each occurrence. Aircraft application: bodily injury $100,000 each occurrence / $300,000 aggregate and property damage $100,000 each occurrence. Coverage must include chemical/pollution liability (if available), products, and completed-operations coverage; a certificate naming the state Division as certificate holder is required. Commercial applicators NOT for hire are exempt.

Workers' compensation

Not specified in the Pes rules; governed by general NH employment law.

Additional financial requirements

Not required; financial responsibility is shown via the Pes 302.03 insurance certificate.

Licensing Fees

Fee	Amount
Application (non-refundable)	$60
Examination	$15
Initial license — sole owner	$60
Initial license — non-sole owner	No separate state fee

Keeping the License Current

Renewal of the Commercial Pesticide Applicator License (for hire) comes due every year. As cited, the renewal fee stands at $60. Two distinct clocks apply and both are confirmed: the certificate of registration renews ANNUALLY at $60 (RSA 430:33), while recertification/continuing education runs on a separate 5-year cycle (Pes 402.01).

Continuing education: Recertification requires accruing at least 12 credits per category in which the applicator is certified over the 5-year period ending December 31 of the fifth year, capped at 48 credits for persons certified in five or more categories (Pes 402.01(o)). Alternatively, the applicator may retake the exams during the fifth year of the cycle in lieu of accruing credits (Pes 402.01(r)).

Reciprocity and License Transfer

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

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

No applicator reciprocity or endorsement was confirmed on the official sources consulted; NH may consider certification from states with comparable EPA-approved programs. Applicants should confirm with the Division of Pesticide Control. NASCLA does not apply — this is a pesticide/structural-pest credential, not a construction-contractor license.

Pest Control Licensing in Neighboring States

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

Maine Pest Control License Requirements — Pesticide Firm License
Massachusetts Pest Control License Requirements — Commercial Applicator Certification, Category 7 (Industrial, Institutional, Structural and Health-Related Pest Control)
Vermont Pest Control License Requirements — Pesticide Company License

Application Process, Step by Step

Enter at the Operational (crew) level. Reach age 18, study the UNH Cooperative Extension category materials, and pass the general/core, regulations, and category written exams at 60% to legally apply pesticides on a crew.
Build Supervisory eligibility. Accumulate the ~5-year education/experience combination under Pes 303.01 (e.g., 3 years registered at the operational level, or a relevant degree plus a growing season) before sitting for supervisory exams.
Pass the Supervisory exams. Pass the general/core, regulations, and each required category exam at 70%, and complete the oral examination required at the supervisory level (Pes 304.04(b)).
Certify in each category of work. Take a separate category exam for each field of work performed — F1 structural, F3 termites/wood-destroying insects, F4 fumigation, and any others — at $15 per category (RSA 430:34).
Secure Pes 302.03 for-hire insurance. Obtain the mandated pesticide liability insurance at the ground/aircraft minimums and file a certificate naming the state Division as certificate holder before doing for-hire work.
Register and staff the firm correctly. Register/renew each applicator's certificate annually at $60 (RSA 430:33), employ at least one Supervisory applicator to supervise and countersign, and staff every crew with at least one Operational licensee.
Maintain certification. Recertify by accruing at least 12 credits per category over the 5-year cycle (capped at 48 for five or more categories, Pes 402.01(o)) or by re-examining in the fifth year (Pes 402.01(r)).

Frequent Application Errors

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

Assuming a business license exists

New Hampshire issues no separate business or company license. A firm that operates without a designated Supervisory applicator, an Operational licensee on each crew, and Pes 302.03 insurance is non-compliant even if it registered a business entity elsewhere.

Doing termite/WDO or fumigation work without the category

Termite and wood-destroying-insect work (F3) and fumigation (F4) each require passing a separate category exam. Performing that work under only an F1 structural certification violates the Pes 304 category rules.

Letting insurance or annual registration lapse

For-hire work requires continuous Pes 302.03 liability coverage with the Division named as certificate holder, and each applicator certificate must be renewed annually at $60 (RSA 430:33). A lapse in either suspends the firm's ability to apply pesticides for hire.

Unregistered technicians applying pesticides

Every crew applying pesticides must include at least one Operational-level licensee supervised by a Supervisory applicator. Sending untrained, uncertified technicians to apply product is a common and serious compliance failure.

Document Checklist

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

Confirm at least one Supervisory-level commercial applicator is employed to supervise applications and countersign operational work.
Confirm each crew applying pesticides includes at least one Operational-level licensee.
Verify current certification covers every category of work performed (F1 structural, F3 termite/WDO, F4 fumigation, etc.).
Obtain Pes 302.03 for-hire pesticide liability insurance at the required minimums with the state Division named as certificate holder.
Renew each applicator's certificate of registration annually at $60 (RSA 430:33).
Track recertification credits (at least 12 per category, capped at 48) across the 5-year cycle, or plan to re-exam in the fifth year.

Other New Hampshire Trade Licenses

If the Pest Control license is not the right fit, the following published New Hampshire trade guides are also covered by CLR:

Questions Applicants Ask

Do I need a license to do pest control in New Hampshire?

Yes. Anyone applying pesticides for hire must hold a Commercial Pesticide Applicator License issued by the NH Division of Pesticide Control. Crew members certify at the Operational level (age 18, written exams at 60%), and each firm must employ a Supervisory-level applicator to supervise and countersign the work.

Does New Hampshire issue a pest control business or company license?

No. New Hampshire runs an applicator-only regime and does not issue a separate business license. A pest control firm operates on its individually certified applicators: it must employ at least one Supervisory-level applicator, place an Operational-level licensee on each crew, and carry the Pes 302.03 for-hire insurance. A single certified applicator is not a licensed company, and there is no company credential to obtain.

What is the difference between the Supervisory and Operational levels?

The Operational level is the entry-level crew credential — age 18, no prior experience, written exams passed at 60%. The Supervisory level is the certified decision-maker who supervises applications and countersigns operational work; it requires the ~5-year education/experience pathway, exams at 70%, and an oral examination.

Do termite or fumigation jobs need a separate certification?

Yes. Termites and other wood-destroying insects fall under category F3 and fumigation under category F4, and each requires passing its own category exam in addition to the general/core and regulations exams. An applicator certified only in F1 structural work cannot lawfully perform F3 or F4 work without adding that category.

Is there a background check or residency requirement?

No. New Hampshire does not require a criminal background check or fingerprinting for pesticide applicator certification, and no state residency requirement is identified in RSA 430 or the Pes rules. Whether an SSN or ITIN is required on the application was not confirmed on an official source; verify with the Division.
