The Story

Started in a Depression. Still Here in 2026.

Ray M. Dewey started knocking on doors in 1929 - the year the stock market crashed and the Great Depression began. He was selling moth crystals and ant traps. No office, no fleet, no investor backing. Just a man, a product, and the conviction that California homes needed protecting from the things that crept inside them.

That door-to-door operation became Dewey Pest Control - and then, in July 1977, Ray's son Steven R. Dewey bought the company from his father, renamed it Dewey Services, Inc., and began a methodical expansion that pushed the branch count from 3 to nearly 30.

Today, Dewey Pest leads the company through its third and fourth generation of family ownership. The branches number in the 30s. The employee headcount sits around 750. The philosophy remains unchanged: local branches, no call centers, same-day service, and pest management that doesn't cost the environment to do its job.

Those five words from the founder's deathbed have been the company's north star through recessions, industry consolidations, and the emergence of national pest control chains that have absorbed hundreds of regional competitors. Dewey Pest & Termite Control has outlasted them all - not by pivoting or disrupting, but by executing that founding instruction with generational consistency.

Four Generations

A Family Tree Rooted in Pest Control

Family businesses typically don't survive past the second generation. The statistics on this are grim: roughly 30% make it to the second, 12% to the third. Dewey Pest & Termite Control is now in its fourth generation of active family involvement - a feat that speaks not to luck but to a deliberate culture of succession planning and company identity.

Chip and Brock Dewey - the third generation - have both held roles across nearly every function in the company. As they put it in a radio interview: they've "pretty much done every job you can name." That hands-on lineage, from fumigator to executive, shapes how Dewey Services operates its network of branches - not as remote franchises, but as locally-run operations with real accountability.

The fourth generation is already active - Brock's oldest son manages the Santa Monica branch - signaling that the company's succession planning is not theoretical. It is already in motion.

Operations

32 Branches. One Standard.

Dewey Pest & Termite Control does not operate like a national chain pretending to be local. It operates local branches - each one community-facing, with technicians who know the regional pest pressures, the climate patterns, and the neighborhoods they serve. From the Bay Area to Bakersfield to San Diego, the network spans every major California market.

The commercial division is where Dewey Pest & Termite Control distinguishes itself most sharply from consumer competitors. Operating in food processing plants, healthcare facilities, and school campuses requires a different level of compliance, documentation, and chemical precision than a typical residential account. Dewey's QA and sanitation compliance inspections are a direct expression of this specialization.

The Approach

Integrated Pest Management Before It Was Fashionable

In an industry that for decades was synonymous with chemical saturation and quarterly spray schedules, Dewey Pest & Termite Control has leaned into Integrated Pest Management - IPM - as its core methodology. IPM starts with inspection and identification, uses targeted interventions, and minimizes chemical exposure through prevention and exclusion techniques.

The company's pest management taxonomy covers over 19 distinct pest types - from termites and bed bugs to mosquitoes, gophers, and silverfish. Each requires a different protocol. Dewey technicians are trained in newly developed application techniques on an ongoing basis, a commitment that keeps the field team current as pest resistance patterns and product formulations evolve.

Competitive Edge

What Private Equity Can't Buy

The California pest control market is not short on competition. National chains, private equity roll-ups, and franchise operations have steadily consumed regional companies across the state. Dewey Pest & Termite Control has watched this happen from the Pasadena headquarters while continuing to grow.

The operating model is the moat. Dewey does not run its California branches from a centralized call center. Each branch is staffed and managed locally. When a customer calls, they reach people who know the area. When a service needs rescheduling, it doesn't bounce through a national routing system.

The employee retention numbers reflect this. Long-tenured field technicians, inspectors, and branch managers who have spent careers at Dewey - not because they have no options, but because the culture of a fourth-generation family business has a different texture than a PE-owned platform.
