NYS PCO Practice Test PDF

The New York State Department of Environmental Conservation (DEC) Commercial Pesticide Applicator exam licenses pest management professionals to legally apply restricted-use and general-use pesticides in New York. The licensing process requires passing a Core exam covering pesticide fundamentals, plus one or more category exams for your specific application area — such as Category 7A for structural and ornamental pest control.

This free printable NYS PCO practice test PDF covers every major topic area tested on the DEC exam: pesticide safety and toxicity, pest identification, application equipment, integrated pest management (IPM), environmental protection, and New York pesticide law. Download it, print it, and study on your own schedule.

NYS DEC Commercial Applicator Exam Topics

Pesticide safety is the most heavily tested Core subject. You must understand the four toxicity categories (I through IV), how signal words relate to hazard level, the routes of pesticide exposure (oral, dermal, inhalation, ocular), and the correct personal protective equipment for each situation. First aid procedures and decontamination protocols are also tested.

Label reading is a legal requirement — the label is the law under FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act). Exam questions frequently ask you to interpret label language regarding application rates, re-entry intervals, pre-harvest intervals, and restricted-use status.

Application equipment questions cover sprayer types (hydraulic, ultra-low volume, granular), nozzle selection, pressure calibration, and how to calculate the correct amount of pesticide per acre or per 1,000 square feet. Calibration arithmetic is a reliable exam topic.

New York-specific laws and regulations are tested on both the Core and category exams. Key statutes include FIFRA at the federal level and New York Environmental Conservation Law (ECL) Article 33 at the state level. Know licensing categories, record-keeping requirements, posting rules, and notification obligations.

NYS Pesticide Applicator Licence Structure

New York issues commercial pesticide applicator licenses in multiple categories. Category 7A (Structural) covers interior pest control in buildings — cockroaches, bed bugs, rodents, and stored product pests. Category 7B (Ornamental and Turf) covers landscape, lawn, and tree pest management. Other categories include agricultural applications, aquatic pest control, and right-of-way vegetation management.

To become licensed, you must pass the Core exam and at least one category exam, then submit a license application to the DEC. Licenses must be renewed every three years with continuing education credits. Use this practice PDF to prepare for both the Core and your chosen category — the content aligns with the official DEC study materials used by exam candidates across New York State.

What is Category 7A in the NYS pesticide licensing system?

Category 7A is the Structural Pest Control category, covering the application of pesticides inside and around buildings for the control of cockroaches, ants, bed bugs, rodents, stored product pests, and other structural pests. It is the most common category obtained by pest control operators (PCOs) working in residential and commercial buildings in New York State.

How do I renew my NYS commercial pesticide applicator license?

NYS commercial pesticide applicator licenses are valid for three years. Renewal requires completing the required number of continuing education (CE) credits in approved categories and submitting a renewal application with the fee to the DEC before the expiration date. CE credits can be earned through DEC-approved training programs, pesticide safety courses, and industry conferences. Check the official DEC website for current credit requirements and approved providers.
