Verify an Ohio Pest Control License and Rodenticide Rules

The Ohio Department of Agriculture (ODA) licenses pest control in Ohio. A company that applies pesticides to other people's property for hire needs a pesticide business license, and it must have at least one person with a commercial applicator license. For rodent work in and around homes and businesses, the category to look for is 10a, General Pest Control.

This guide explains the license types, what to ask before you hire, and the federal rules that govern rat and mouse poisons.

Who needs a license in Ohio

Ohio State University's Pesticide Safety Education Program, which runs training and testing for Ohio applicators, describes a commercial applicator as someone who applies pesticides for hire, on publicly accessible sites such as apartment complexes, restaurants and schools, or while working for a government agency. Commercial applicators must be licensed to use both restricted use and general use products.

A pesticide business license is required for a business that applies pesticides to another person's property for hire or solicits and takes orders for applications. OSU's licensing page says each company needs one, the business must have at least one person holding a commercial applicator license, and the business license requires proof of liability insurance.

Some technicians are trained servicepersons instead of licensed applicators. Under the rules OSU summarizes, a trained serviceperson works under the direct supervision of a licensed commercial applicator at the same company, must be trained before applying products, and the supervising applicator must be within 25 miles or available within two hours when an application is made.

License categories that cover rodents

Ohio's commercial license is divided into categories by site and pest. Two matter for rats and mice:

Category 10a, General Pest Control: non-fumigant treatments in or around buildings such as homes, businesses, food facilities, schools and hospitals. It covers pests including rodents, but excludes pest birds and wood-destroying insects.
Category 7, Vertebrate: control of pest birds, rodents and other vertebrates declared pests by the director, excluding fumigants and work covered by Category 10.

For a rat or mouse problem in a home, restaurant or apartment building, ask whether the technician or their supervisor holds Category 10a. Category 10c covers fumigation of structures and commodities for invertebrate pests, which is not standard rodent work.

OSU's licensing page says applicators pay an annual fee and must recertify every three years.

How to check a license

Ask the company for its ODA pesticide business license number and the name and license number of the technician or supervising applicator. A legitimate provider will give these without hesitation. Then:

Contact ODA's pesticide program to confirm the business and applicator licenses are current. Its pesticide pages are on the Ohio Department of Agriculture website.
Ask which category the applicator holds, and look for 10a for rodent work in buildings.
Ask for proof of liability insurance. Ohio requires it for the business license.
Ask whether the person coming to your home is a licensed applicator or a trained serviceperson working under one.

This site connects callers with independent providers. Checking license and insurance before work starts is the homeowner's responsibility, and the steps above make it quick.

Federal rules on rat and mouse poison

Rodenticides are regulated by the US Environmental Protection Agency, and several rules shape what can be sold and how it is used:

Consumer products: pelleted baits are no longer permitted in consumer rodenticide products. Consumer products are ready-to-use bait stations with block or paste bait, labeled for indoor use or for use outdoors within 50 feet of buildings.
Consumer active ingredients for mice and rats are bromethalin, chlorophacinone and diphacinone.
Second-generation anticoagulants, such as brodifacoum, bromadiolone, difenacoum and difethialone, are no longer registered for consumer products. They are registered only for commercial and structural pest control markets.
Professional products may not be sold in consumer stores such as drug, grocery or hardware stores.
For professional products, tamper-resistant bait stations are required where children under six, pets or nontarget wildlife may get to the bait, and for all outdoor above-ground placements.
Outdoor burrow baiting is allowed only with pelleted bait placed at least six inches down active rat burrows.

In November 2024, EPA released its final Rodenticide Strategy and biological evaluation on how 11 rodenticides affect endangered species. EPA says the strategy does not itself impose requirements. Protective measures are to be added through product labels or registration terms where listed species are present.

We did not find an Ohio rule that adds rodenticide restrictions beyond federal label requirements and state licensing, so follow the product label and use a licensed applicator for professional products.

Questions to ask before you hire

What is your Ohio pesticide business license number, and who is the licensed applicator on my job?
Does the applicator hold Category 10a, General Pest Control?
Can you show proof of liability insurance?
Will you use traps, bait or both, and where will each go?
If bait is used, what product, in what kind of station, and how is it kept from kids and pets?
Does the quote include sealing entry points, and with what materials?
How many follow-up visits are included, and what happens if activity continues?
Will I get a written report after each visit?

A provider who answers these clearly is easier to hold to the plan.

Reading a store-bought product label

If you use consumer products yourself, the label is the law. EPA requires pesticide users to follow label directions, and consumer rodent baits are sold only as bait stations with block or paste bait. The label says whether a station is for indoor use only or for outdoor use within 50 feet of a building, and whether it is tamper-resistant to children and dogs.

Keep stations out of reach of children and pets anyway, check them often and dispose of empty or damaged stations as the label directs. Rodents that eat bait can die in walls, which is why many people prefer snap traps indoors.

Why it matters in Cleveland

In March 2022, the Ohio Department of Agriculture issued a public health alert after a licensed applicator tipped it off that rodenticides had been placed in accessible areas in several Cleveland-area homes. ODA warned that these products are toxic to people and pets and should only be placed in areas people and pets cannot reach.

That case is a good reminder to ask any provider where each product will go, what kind of station holds it and how it is kept away from children and pets. Many technicians rely on snap traps indoors, which the CDC recommends, and keep bait outside in locked stations.

Frequently asked questions

Does a handyman need a license to seal holes?

Sealing gaps with mesh and caulk is not a pesticide application, so a pesticide license is not required for that part. Anyone applying rodenticides or other pesticides for hire needs ODA licensing.

What license category should a rodent technician have?

For rats and mice in or around buildings, Category 10a, General Pest Control. Category 7 covers vertebrate pests outside the Category 10 settings.

Can I buy professional rat poison in Ohio?

EPA rules bar professional rodenticide products from consumer stores, and second-generation anticoagulants are not registered for consumer products. Consumer products must be bait stations with block or paste bait.

What should I do if I think a provider misused rodenticide?

Do not touch or move the product. Contact the Ohio Department of Agriculture's pesticide program, and call your doctor or poison control if anyone was exposed.
