How to Verify a Pest Control License in California

The three branches

The board licenses three branches of structural pest control:

• Branch 1: fumigation with poisonous or lethal gases, for household and wood-destroying pests
• Branch 2: household pest control, excluding fumigation with gases. This is the branch for rats and mice.
• Branch 3: wood-destroying pest control, such as termites, using insecticides or structural repairs, excluding fumigation

Each branch has its own exam, and one person can hold licenses in more than one branch. For a rodent job, look for Branch 2.

The three license types

The board issues three levels of license:

• Applicator: the entry-level license. Applicators apply pesticides for a registered company and may not contract for work or work on their own. Available for Branch 2 and Branch 3.
• Field Representative: can secure work, identify infestations, inspect, apply pesticides and bid or contract for work on behalf of a registered company. Cannot work independently.
• Operator: has the same duties as a Field Representative, and can also own and operate a company or serve as the qualifying manager for another owner.

The board says all three can only perform work while working for a registered structural pest control company. So you are checking two things: the company's registration and the person's license.

How to look up a company or technician

The board's verification page sends you to the Department of Consumer Affairs License Search at search.dca.ca.gov. To use it:

• Choose Structural Pest Control Board in the Board and Bureaus field
• Search by the person's first or last name, the business name, the license type or the license number
• Use Advanced Search to filter by location or license status

Cancelled licenses and registrations do not show up in the search. The board says to contact it directly for information about those. The board's household pests brochure also says you can call its Enforcement Unit to confirm a company's registration or an individual's license, and that disciplinary actions are posted on its website.

What to ask for at the door

The board's household pests brochure says to ask to see proof of licensure before work begins, and that licensees should carry a board-issued ID card showing their license type and expiration date. It also lists consumer rights:

• Before any pesticide is applied, you must get written notice naming the pest, the pesticides and their active ingredients
• If you ask, the company must give you the name of each pesticide applied within 24 hours
• For a periodic service contract, the notice must state how often treatment will happen

Keep those notices with your service reports. See rodent monitoring plans for what a periodic contract should spell out.

If something goes wrong

The board's brochure says to contact the company first if you are unhappy with the service. If that does not work, contact the board, which will try to mediate. You can download a complaint form from the board's website. The board says it can compel a registered company and licensee to complete a contract, and that help may include a financial settlement, though that is not guaranteed and other legal channels may be needed.

California's rodenticide rules

California has tightened its rules on anticoagulant rat poisons in steps since 2020, and they limit what a provider can use around your home.

AB 1788 came first. The governor signed it on September 29, 2020, and it took effect January 1, 2021. The Department of Pesticide Regulation's enforcement letter ENF 20-20 says it prohibits most uses of four second-generation anticoagulants (brodifacoum, bromadiolone, difenacoum and difethialone), including residential or home uses, until DPR completes its reevaluation of them.

AB 1322 added diphacinone, a first-generation anticoagulant. DPR's enforcement letter says most uses of diphacinone have been prohibited since January 1, 2024, including most residential, industrial and institutional uses such as around restaurants and schools. Diphacinone is a restricted material, and products labeled for prohibited uses can be sold to end users only by licensed pest control dealers.

AB 2552 took effect January 1, 2025. According to DPR's enforcement letter ENF 24-20, it revised Food and Agricultural Code section 12978.7 so that most uses of the first-generation anticoagulants chlorophacinone and warfarin are prohibited too, again including residential or home uses. It also added civil penalties of up to $25,000 per day for violations. Taken together, these laws bar most residential use of both first- and second-generation anticoagulant rodenticides in California.

The exemptions in ENF 24-20 are specific. They include mosquito and vector control districts, government agencies and utilities protecting water and hydroelectric infrastructure, responses to an urgent public health need declared by a state or local health officer, medical waste generators, FDA-registered drug plants, agricultural sites, and food warehouses, food manufacturing or processing plants, factories, breweries and wineries. Houses and apartment buildings are not on the list.

UC IPM's Pest Notes on rats, revised June 2025, says three active ingredients are registered for rats and house mice in California: bromethalin, cholecalciferol and zinc phosphide. Zinc phosphide is not available to the general public. UC IPM also says almost all bait used in and around structures must be in bait stations within 50 feet of a structure, and that tamper-resistant stations are generally required where children, pets or other animals could reach the bait.

DPR has further rules on anticoagulant rodenticides pending. Check DPR's website for their current status. Ask any provider which product they plan to use, where it will go and why.

A short checklist before you sign

• Look up the company's registration and the technician's Branch 2 license
• Ask to see the technician's board ID card
• Get the inspection findings, the sealing scope and the price in writing
• Ask what baits or traps will be used and where
• Ask how many return visits are included
• Read the cancellation and retreatment terms

See rodent control cost in San Diego to judge the price, and what to say when you call for a script.

Red flags to watch for

A few signs suggest you should slow down before hiring. The technician cannot show a board ID card or will not give a license number. The company name does not appear in the license search, or the registration is under a different name than the one on the truck or invoice. The quote is verbal only, or the written quote leaves out sealing and return visits. The provider pushes a long service contract on the first visit before inspecting the attic. Or the provider plans to use a product that sounds like one of the restricted anticoagulants around your home without explaining which exemption applies.

None of these proves a problem on its own, but each is worth a question. A licensed provider can answer all of them quickly.
