Continuing its California expansion, Orlando, Fla.-based Certus Pest has acquired Keystone Pest Control, headquartered in Hayward, Calif.

Terms were not disclosed; PCO M&A Specialists, a division of PCO Bookkeepers, represented and acted as exclusive financial advisor to Keystone Pest Control in this transaction.

The Northern California company has served pest control customers in the Bay Area for nearly 20 years. Co-owners John Pirrone and Steve Dietrich founded the company in 1992 after working in the industry for many years.

“Steve and I formed Keystone to offer our community better quality pest control, and it’s important to us that we’ve chosen a company to hold up that tradition,” Pirrone said.

Dietrich added, “The fact that Certus is founded and run by former technicians gave us the confidence that our hands-on approach to ensure the best customer experience would continue, even when John and I are no longer managing day-to-day activities.”

Certus enters the San Francisco, Calif., market with the acquisition.

Mike Givlin, CEO and co-founder of Certus, said, “We’re excited to expand into Northern California, especially with the strong foundation that Keystone Pest Control provides.”


In 2020, Certus completed its first acquisition in California with Rodent Pest Technologies.

So far in 2021, the company has purchased several companies including DeLand, Fla.-based Aaron Pest Control, Palm Desert, Calif.-based Bug Guys Pest Control, Gilbert, Ariz.-based Bryant Pest Control, its first company in Georgia with Peachtree Pest Control, its first in Nevada with Las Vegas Pest Control, and Palm Desert, Calif.-based Bug Guys Pest Control.

Certus now operates in California, Georgia, Washington, Oregon, Florida, Idaho, Arizona and Nevada. The company expects to continue to grow in its existing markets and enter new markets into 2021.

In 2019, CEO and co-founder Mike Givlin partnered with Imperial Capital, a mid-market private equity firm from Toronto, Canada. Then Certus was launched and entered the pest control market in 2019 in the Pacific Northwest with its first two acquisitions: Mathis Exterminating, Puget Sound, Wash., and Eco Elite Pest Control, Seattle, Wash.
