Pest Control Licensing: The Federal Framework

What this page is. The federal framework that every pest control licence in the United States is built on, verified line by line against the Code of Federal Regulations. It is the part that does not change when you cross a state line. State-specific exam, fee and continuing education detail sits on top of this, and we are verifying that state by state.

The correction most licensing guides need

A large share of the pest control licensing guides online state that the EPA defines 10 commercial applicator categories and that structural work falls under “Category 7”. That describes the rule as it stood before 2017.

The current rule, at 40 CFR 171.101, defines 15 commercial applicator certification categories, lettered (a) through (o). Structural work is category (g), Industrial, institutional, and structural pest control. There is no Category 7 in the regulation as it reads today. If a guide is telling you there are 10 categories, it has not been updated in nearly a decade, which is worth knowing before you rely on the rest of it.

The 15 commercial applicator categories

What category (g) actually covers

The regulation defines it as commercial applicators using or supervising the use of restricted use pesticides in, on or around: food handling establishments, packing houses and food processing facilities; human dwellings; institutions such as schools, hospitals and prisons; and industrial establishments including manufacturing facilities, warehouses, grain elevators, and any other structures and adjacent areas, public or private, for the protection of stored, processed or manufactured products.

Two things follow from that wording. The category is defined by where you work, not which pest you treat, so a technician doing ants in a school and a technician doing rodents in a warehouse sit in the same category. And it is defined in terms of restricted use pesticides, which is why general use products can sometimes be applied under looser rules. States routinely require licensing anyway, and most do.

The three requirements that apply everywhere

Minimum age of 18

A commercial applicator must be at least 18 years old. A noncertified applicator working under the direct supervision of a certified applicator must also be at least 18, with one exception: 16 is permitted where a specific set of conditions in 40 CFR 171.201 is met.

Certification expires after five years

Each commercial and private applicator certification expires five years after issuance unless the applicator is recertified. This is the federal ceiling, and it is the number most often misstated. Critically, a certifying authority may establish a shorter certification period, and many states do. Five years is the longest your certification can run, not the length it will run in your state.

Recertification is achieved either by written examination or through approved continuing education. To keep certification continuous, you must be recertified before the current certification expires, not after.

Certification is per category

Certification is granted in the categories an applicator seeks it in. Adding whole-structure fumigation or soil fumigation to a structural licence means adding a category, with its own competency standard, not simply renewing the one you have.

How states layer on top

The federal rule is a floor. Every state must meet or exceed it, and states run the actual certification programmes through their departments of agriculture or equivalent agencies. What varies between states, and what you have to check locally:

• The tier structure. Most states distinguish the technician working under supervision, the certified applicator or operator who can work unsupervised, and the business licence the company itself holds. The names for these differ everywhere.
• The certification period. Five years is the federal maximum. Shorter cycles are common and lawful.
• Continuing education. Hours required, which subjects count, and how many can be earned online.
• Exam structure. Nearly all states require a core or general standards exam plus at least one category exam.
• Fees. These range from nominal to substantial and often stack: exam fee, licence fee, business licence, and a bond or insurance requirement.
• Reciprocity. Some states recognise certification from neighbouring states. Many do not.

We are verifying these state by state against each state agency’s published fee schedule and regulations rather than aggregating them from secondary guides. That table will publish here when it is checked rather than when it is merely assembled. See our methodology for why we would rather be late than wrong.

Data limitations

• This page covers federal minimums only. It is not sufficient to get licensed in any specific state, and complying with it does not make you compliant locally.
• The CFR text was retrieved for the 2026-01-01 edition. Regulations are amended. Check the current text before relying on it for a licensing decision.
• Restricted use pesticides are the trigger for federal certification. Many state licensing requirements extend beyond that to any commercial application, so the federal scope understates what you will actually need.
• We are not lawyers and this is not legal advice. Licensing questions with money attached belong with your state regulatory agency, which answers them for free.

Frequently asked questions

How many EPA pesticide applicator categories are there?

Fifteen commercial applicator certification categories, lettered (a) through (o), under 40 CFR 171.101. Category (a), agricultural pest control, is further divided into crop and livestock subcategories. Guides citing 10 categories are describing the pre-2017 rule.

Which category do I need for structural pest control?

Category (g), Industrial, institutional, and structural pest control. Add category (n) for whole-structure fumigation and (m) for soil fumigation. Firms selling lawn and ornamental work usually need (c) as well.

How often do I have to recertify?

Federal rules cap certification at five years from issuance. Your state may set a shorter period and many do, so five years is a maximum rather than a default. Recertify before expiry, since certification does not continue uninterrupted otherwise.

How old do you have to be to be a pest control technician?

18 to be a certified commercial applicator. 18 to work as a noncertified applicator under direct supervision, dropping to 16 only where the specific conditions in 40 CFR 171.201 are met.

Do I need a licence to apply general use pesticides commercially?

Federal certification requirements attach to restricted use pesticides. Most states, however, require a licence for commercial application regardless of product classification, so in practice the answer is usually yes. Check with your state agency.
