State-by-State
25(b) Licensing Requirements

Do you need a license to apply 25(b) - Natural products - commercially in your state?

If you are a pest control professional, you likely already have all your necessary licenses to operate in your state. However, if you are new to the pest control industry, you might be curious if a license is required in your specific state.

In some instances, Natural products require the same licenses as conventional synthetic pesticides. In other states, however, the rules for Natural products, or 25(b) exempt products, are different.

The following list is our best effort to collect the information as we understand it today. These are not the official rules from the state. Your state and local regulators are the only people who can give you the definitive correct answer as to which license is required. Please use this webpage, it’s links, and our video as guidance to help you investigate your relevant laws, regulations, and rules. 

Check out the video for a quick overview of all 50 states.

For your specific state, continue to the list below.

Alabama

Do I need a license to apply 25(b) – Natural products – for commercial services in Alabama? 

If you are applying 25(b) Natural products in Alabama you will need a license, and might have to follow some extra steps. Here is an explanation of what I mean. From the Alabama Professional Services rules 80-10-9, pest control work where an individual or company is providing their services for hire is considered Professional Services work and the person or company must first obtain proper certification and then apply for an annual license. 

If you are applying Stop the Bites! Mosquito and Tick, or any mosquito and tick control, this type of control falls under Alabama’s Household Pest Control category. This means the person applying will be required to be examined and obtain proper certification for that type of work along with getting a business license to perform said work. 

Alaska

Do I need a license to apply 25(b) - Natural products - for commercial services in Alaska?

The short answer is yes, you need a license. In Alaska, state regulations 18-AAC-90.300 requires you to be a Certified Pest Applicator for commercial application. This means if you use, or supervise, the use of pesticides on property other than your own, it is considered “custom, commercial, or contract” application and requires certification. This regulation applies to all pesticides, whether they are 25(b) or not! For more information on pesticide licensing in Alaska, click here

Arizona

Do I need a license to apply 25(b) – Natural products – for commercial services in Arizona? 

Yes, you do. The State of Arizona says that any work in the pest control field requires a license, regardless if it is a natural product or not. This certified applicator license would need to be issued under the Industrial and Institutional category. The Industrial and Institutional category is defined as pest management in or about a residential or other structure excluding anti-microbial pest management, fungi inspection, or pest management covered by another certification category. This includes public health pest management such as adult mosquitos.

California

In California, regardless of if an individual is applying a FIFRA 25(b) exempt product, the products are still pesticides and individuals for hire are still subject to the Department of Pesticide Regulations licensing requirements. 

This means that if an individual is going to spray mosquito treatment in your yard for hire – or any form of pest control – that person must possess a DPR Pest Control Business (PCB) License. In addition, the PCB must have an individual responsible at each business location to supervise the operations of the business. This supervising individual must possess a DPR Qualified Applicator License (QAL) and hold the appropriate pest control category(ies) for pest control activities conducted by the PCB.
