  • N/A means not scored or not on file. A factor with no usable inputs is left out and the company’s other weights are scaled up (renormalized).
  • Google reviews in California is the count-weighted average rating and the review count across the company’s Google listings in California. Each company’s overall Handshake Score is in the list above; it can be lower than the State Score because it also takes points off a company with fewer than 10 locations, which a State Score doesn’t.

These companies have a location on file in California but not enough in-state evidence to be ranked here.

How we ranked

The State Score runs from 0 to 10 with the same factors and weights as the Handshake Score. For each factor, when a company’s research record ties evidence to California, only the California evidence counts and the table marks the factor In-state. When it can’t, the factor uses the company’s whole record and is marked Company-wide. Licensing and the legal record can be marked In-state + company-wide: California records count together with federal and multi-state ones.

The review-volume and verification-depth adjustment from the overall score applies too, with its thresholds scaled to the size of California’s Google review market on file compared with the Pacific Northwest’s, where the thresholds were set. How many states, or how many locations, a company has doesn’t change its State Score.

To be ranked, a company needs a location on file in California and at least 100 Google reviews on its California listings. Companies with a location here but less in-state evidence are listed under “Also operates in California.”

Ties are broken by in-state Google review volume. A factor with no usable inputs is left out and the other weights are scaled up, exactly as in the overall score. The Handshake Score on each company’s page rates its whole operation in the region it is scored in and also takes points off a company with fewer than 10 locations of its own, which a State Score doesn’t.

This ranking covers the companies we’ve researched and verified in California. It isn’t every pest control company in California, and we may add more.

Common questions

What is the best pest control company in California?

In the October 11, 2026 State Score run, Pest Pros Pest Solutions ranks first in California by State Score (8.8 out of 10), followed by Next Level Pest Control (8.8) and Thrasher Pest Control (8.7).

How is the California State Score different from the Handshake Score?

The Handshake Score on each company’s page rates its whole operation in the region it is scored in. The California ranking uses the State Score, which counts California evidence where the record has it (Google reviews, BBB complaints and pesticide licenses) and the company’s whole record for the rest. A company needs at least 100 Google reviews on its California listings to be ranked here.

Which companies operate in California but aren’t ranked here?

Plunkett's Pest Control. It has a location on file in California but too little in-state evidence to rank: a company needs at least 100 Google reviews on its California listings.

Which pest control companies have the most Google reviews in California?

On their California listings: Aptive Pest Control (58,356 reviews, 4.7 average), Orkin (50,324 reviews, 4.8 average) and Terminix (28,122 reviews, 4.7 average).

Does this list every pest control company in California?

No. This ranking covers the companies we’ve researched and verified in California. It isn’t every pest control company in California, and we may add more. Companies with a location here but less in-state evidence are listed as also operating in California.

Can companies pay for a better rating?

No. We independently review every company we cover. Companies can’t pay to change their ratings.
