How to Verify an Ohio Pest Control License

The check takes about five minutes and costs nothing. Do it before anyone sprays, and before you sign a contract. Ask for a free inspection and a written price before any treatment.

Two licenses, and you should ask about both

Ohio licenses the business and the people separately.

• The business. Under Ohio Revised Code 921.09(A), "No person shall own or operate a pesticide business without obtaining a license from the director of agriculture," with a separate license for each business location. Division (D) says the business must employ at least one commercial applicator for each location, and division (E) makes the owner responsible for what each employee does with pesticides.
• The applicator. ORC 921.06 requires a commercial applicator license to apply pesticides for a pesticide business without direct supervision. OSU Extension's licensing fact sheet (ANR-0140) says anyone applying pesticides to another person's property for hire needs one.

The Ohio Department of Agriculture (ODA) adds that business licenses run one year, expire September 30, and require a current certificate of insurance on file with the department.

Step by step

1. Ask the company for its ODA pesticide business license number and the name of the applicator who will do the work. A legitimate company answers this without fuss.
2. Open ODA's Pesticide Applicator Search. It lists every licensed commercial and private applicator in Ohio, and ODA last updated it on October 26, 2026.
3. Search by the applicator's name or license ID. Each entry shows the license ID and the applicator's county. It also shows the expiration date, the license type and the categories.
4. Confirm the type reads Commercial Applicator. Work on someone else's property for hire needs the commercial license, per OSU Extension.
5. Check the expiration date. Commercial licenses expire every September 30, per OSU Extension.
6. Check that the categories match your job, using the table below.

Stop and ask questions if you see any of these:

• The company will not give you a license number, or says it will send one later.
• The expiration date has passed. Every commercial license ends on September 30, so a date of September 30 this year means the license is due for renewal. If it is already October, ask ODA whether a renewal is pending before you rule the company out.
• The applicator holds 10a only and the job is termites.
• Nobody at the company can name a licensed applicator at all.

The page also offers the whole list as a CSV download. From that file, as of October 26, 2026, 1,085 commercial applicators list a Franklin County address. 290 of them hold category 10a and 96 hold 10b. Those counts go by the applicator's own listed address, so someone who lives in a neighboring county and works in Columbus is not in that number. More local figures are on our Columbus pest data page.

If you want help matching a pest to the right kind of company, send a photo first.

Match the category to the job

A commercial license is only half the answer. The category on it has to fit the work. These are the ones that matter for a house, from OSU Extension fact sheet ANR-0140 (September 27, 2023):

Category	What it covers	When you need it
10a	General Pest Control	Routine household pests in and around the house
10b	Termite Control	Any termite treatment, including bait systems
10c	Fumigation	Tenting or fumigating a structure
10d	Mosquito, House Fly, and Other Vector Control	Yard mosquito spraying
12	Wood Destroying Insect Diagnostic Inspection	A termite (WDI) inspection for a home sale

For a termite job, I would not hire anyone whose applicator lacks 10b. For a real estate termite report, ODA says the inspector needs category 12 and the company needs a pesticide business license, even if it will not treat. Our termite page covers what that report includes.

OSU also says licensed applicators need five hours of recertification credit every three years to keep the license. The search does not show those hours, only whether the license is current.

When the seller is not the applicator

The person who sells you the service and the person who sprays are often different people. Here is how to check each setup.

The company that sells but does not treat

ODA issues a separate pesticide solicitation business license to companies that sell pest control and contract with a licensed pesticide business to do the actual application. A company holding only that license is prohibited from applying pesticides itself, per ODA. If the name on your contract differs from the name on the truck, ask which company holds the pesticide business license and which applicator is coming. Then look up that applicator.

The summer door-knocker

A salesperson at your door is usually not the person who will treat your house. Get the company's name and the applicator's name before you sign anything, and check both. Ohio gives you until midnight of the third business day to cancel most sales signed at home, and the seller may not start the service during that window (ORC 1345.22). The quote guide has the details.

The landlord's own maintenance worker

OSU Extension's fact sheet lists apartment complexes with more than four units among the places where applying pesticides takes a commercial applicator license. If you rent in a large building and someone from maintenance shows up with a sprayer, you can ask for their license number like anyone else. Our renters guide covers what Ohio landlords have to do about pests.

Checking the business itself

The applicator search lists individuals, not companies. I could not find a public ODA search for pesticide business licenses. So ask the company for its business license number and, if anything feels off, call ODA's Pesticide and Fertilizer Regulation section at 614-728-6987 or email pesticides@agri.ohio.gov to confirm it. A confirmed business license also tells you something about insurance, because ODA requires a current certificate of insurance on file for as long as the license is valid.

A few more checks are worth the time:

• The applicator's listed name should line up with the person the company names. If the technician at your door is not in the search, ask who the supervising licensed applicator is. ORC 921.06 allows some application work under direct supervision.
• Look up the company's complaint history with the Better Business Bureau and read how complaints were answered, not only how many there are.
• Get the price and the visit schedule on paper, along with the cancellation terms.

Wildlife is a different license. Under ORC 1531.40(B)(1), anyone removing raccoons or other nuisance wild animals for hire needs a license from the chief of the ODNR Division of Wildlife; see our wildlife removal page.

If something goes wrong

For a question about a license or a pesticide application, start with ODA at 614-728-6987. For a billing or contract dispute, the Ohio Attorney General's Consumer Protection Section takes complaints through its online complaint form or at 800-282-0515. The AG's office asks for everything that explains the problem and what you have done to resolve it, so keep the contract and every receipt.

We only refer companies that hold an Ohio Department of Agriculture pesticide business license and send licensed commercial applicators. You can still run every check above on whoever shows up, and I would.
