We focus on solving pest problems at their source rather than just addressing their symptoms. By utilizing an integrated pest management (IPM) approach—targeting every facet of a pest infestation and emphasizing prevention and protection—we’ve helped countless people across the West Coast.
Since being founded in 1921 by Carl Strom, our yellow trucks—now white—and the Mr. Little mascot have been familiar sights for West Coast residents.
Our legacy is built on pioneering innovative pest control methods, bringing modern, green pest management and personalized care to those who need them.
In the more than 100 years we’ve been here, we’ve built strong relationships and gained a real understanding of the pest pressures you deal with every day. We know the climate, the seasons, and the common pests in your area—because we live and work here, too.
At the same time, we’re backed by the global strength of the Rentokil family of brands. That means our work is supported by advanced research and development centers, experienced entomologists, and ongoing innovation in pest control methods.
Choosing a pest control provider is about more than a single service. It’s about choosing a dedicated partner to keep your home happy and healthy, and your business running smoothly, for the long term. Here’s how we maintain the highest standards possible:
Our technicians live in the surrounding areas they serve, and understand local pest trends
Considerate of people, wildlife, pets, and the planet
We’re committed, and we’re not satisfied until you are
Our technicians get to know their customers and understand their spaces and unique needs. Read real reviews by real people to find out why we’re trusted by thousands of customers across the West Coast for residential and commercial pest control.
Our technicians live and work in the communities they serve, so they understand the pest pressures you're up against — whether that's scorpions in the desert heat or rodents looking for shelter as temperatures drop. That local knowledge, combined with expert training, means we can help manage hundreds of pest species with targeted, integrated solutions built around your home or business.
Western Exterminator is part of the Rentokil family of brands. Rentokil operates in more than 90 countries, giving us access to global research, training, and resources while keeping service local.
