California Pest Control Licensing: How to Check a Company

Pest control companies that treat homes and buildings in California are regulated by the Structural Pest Control Board. Every company must hold a Board registration and name a licensed Operator as its qualifying manager. It must also carry $500,000 in liability insurance, post a $12,500 bond, and give written pesticide notices before treatment starts and after each visit. Any license or registration number can be checked in minutes through the state's online license search.

Who regulates pest control companies in California?

The Structural Pest Control Board, part of the Department of Consumer Affairs, licenses people and registers the companies that inspect, bid on or treat pests in buildings. The Department of Pesticide Regulation (DPR) decides which pesticide products may be sold or used in the state and oversees local enforcement. County agricultural commissioners enforce pesticide rules locally and can assess civil penalties or suspend a company's county registration.

The legal definition of structural pest control is broad. Advertising, inspecting, identifying infestations, writing estimates or bids, and applying pesticides or traps all require a license and a company registration. Companies must also register with the agricultural commissioner in each county where they work and file a monthly pesticide use report there.

What does a Branch 2 license cover?

Branch 2 is the general pest license. It covers household pests such as ants, cockroaches, bed bugs, spiders, fleas, rats and mice, by any method except fumigation with poisonous or lethal gases. Branch 1 covers fumigation with those gases, and Branch 3 covers termites and other wood-destroying organisms. A company may only work in the branches its registration covers.

A Branch 2-only company cannot legally inspect for or treat termites, so a termite diagnosis from a general pest technician is a warning sign. PesPro does not treat termites or mosquitoes.

Applicators, licensed in Branches 2 and 3, apply pesticides for a registered company but cannot sign contracts. Field Representatives can hold any branch and also inspect, identify pests, submit bids and sign contracts for the company. Operators hold the highest license. An Operator can own and run a company, or serve as qualifying manager for a company someone else owns.

How do I verify a pest control license in California?

The Board's license verification page sends you to the Department of Consumer Affairs license search. Choose the Structural Pest Control Board, then search by business name, person's name or license number. Canceled licenses and registrations do not appear in the results, so a "no match" is itself an answer. Check four things:

Company registration. It starts with PR (PesPro's is PR-6378) and must show a current status.
Branch. For ants, roaches, bed bugs or rodents the company needs Branch 2.
Qualifying manager. A licensed Operator must be designated to supervise the company.
Technician. Ask whose name is on the Field Representative or Applicator license and look it up too.

What must a licensed company disclose before and after treatment?

Before a Branch 2 application, Business and Professions Code section 8538 requires a written notice to the owner or owner's agent and to any tenant. It must name the pest, list each proposed pesticide and its active ingredients, and include the state's caution statement with the words "pesticides are toxic chemicals." For recurring service it must also state the treatment frequency. It can be sent by first-class mail or email, posted on the property or hand delivered. Skipping it is a misdemeanor.

For a periodic contract, the notice is required at the first treatment and again whenever the pesticide changes. Since January 1, 2025, Board regulation 1970.42 adds a post-application notice after every visit, which can be a door hanger, an invoice or a billing statement. It must list each pesticide applied, the date of service, and the company's name, address and phone number.

What insurance and bonding must a registered company carry?

The Act sets a floor. Every registered company must carry liability insurance of at least $500,000 per loss for bodily injury and $500,000 per loss for property damage. It must also post a $12,500 surety bond, which protects customers harmed by fraud, dishonesty or other violations of the Act. A workers' compensation certificate, or a formal exemption, must also be on file with the Board.

Ask for a certificate of insurance before commercial work begins. PesPro is fully insured with $2 million in liability coverage. What a documented multi-unit program includes is on the property managers page.

Is QualityPro the same as a license?

No. A license is the legal minimum. QualityPro is a voluntary credential from the National Pest Management Association with standards for business practices, training and customer service beyond the state license. Fewer than 3 percent of pest control companies in the United States hold it, and fewer than 12 companies in California do. PesPro is one of them.

GreenPro is the NPMA's add-on certification for reduced-risk, IPM-based service. PesPro holds it, but a GreenPro plan is something you ask for when you book a general pest control subscription, not the default.

What are the red flags when hiring a pest control company?

Walk away if you see:

No registration number on the truck, quote or website.
A technician who cannot show a Field Representative or Applicator license in their own name.
A firm bed bug or cockroach price given over the phone, with no inspection and no written scope.
No written pre-application notice, or a refusal to name the products applied or share their labels.
Termite or fumigation offers from a Branch 2-only company.
Routine spraying as the whole plan, with no monitoring, baiting, trapping or exclusion.
Guarantees that are not written down.

A compliant company identifies the pest first and puts the products, visits and price in a written quote. For bed bugs and cockroaches, follow-up visits are built into that quoted plan; see bed bug treatment and cockroach control for the scope.

What can you do if a company breaks the rules?

File a complaint with the Board through its online complaint page. The Board investigates unlicensed activity, false advertising, missed infestations, substandard or incomplete work and fraud, but it has no authority over payment disputes. Complaints must be filed within two years of the problem, or within four years for fraud, gross negligence or misrepresentation. Pesticide misuse can also be reported to the county agricultural commissioner.

Frequently asked questions

Does every pest control technician in California need a license?

Yes, with one narrow exception for trainees. Anyone who inspects, identifies pests, quotes prices or applies pesticides must hold an Applicator, Field Representative or Operator license. A new employee may apply pesticides as training for up to 90 days from hire. A licensed Field Representative or Operator must be present the entire time, and the period cannot be extended. Ask to see the license in the technician's own name.

Can a general pest company treat termites or mosquitoes?

Termites, no. Termites and other wood-destroying organisms fall under Branch 3, and fumigation under Branch 1, so a Branch 2-only company cannot inspect, bid or treat for them. Mosquitoes are a different question: some general pest companies offer mosquito service, but PesPro does not. For termites, call a Branch 3 company; for mosquito problems, contact your local vector control district.

How does the PesPro 30-day guarantee work?

It has two tiers. For cockroaches, bed bugs and rodents, a third visit within 30 days costs nothing extra if the problem reappears. For all other pests, a return visit within 30 days costs 30 percent of the original price. Follow-up visits for bed bugs and cockroaches are paid visits built into the quoted plan.
