After an 18-month search, Jonathan Kaplan and Brant Claussen, the founders of GAF Partners, have announced the acquisition of Hydrex Pest Control Co., one of San Diego’s oldest and most trusted names in pest management. The company was built over generations by the Colton and Stansbury families.
Founded in 1921, Hydrex has one of the longest operating histories of any pest and termite control company in Southern California: 105 years of serving families, protecting homes, and building relationships that span generations. Hydrex offers residential pest control, rodent control and exclusion, termite treatment, and wood repair services — the kind of essential, hands-on work that keeps San Diego homes safe and comfortable year-round.
Jonathan Kaplan, the company’s new CEO commented: “When we first learned about Hydrex, we were immediately struck by the depth of loyalty between this company and its customers. People have been calling the same phone number and working with the same team members for decades — that kind of trust is incredibly rare and genuinely special. We intend to honor it.”
Brant Claussen, who joins as Senior Vice President, added: “Hydrex has built something that most businesses only dream of — authentic, enduring relationships. Our role is to be good stewards of that legacy while helping more San Diego and Imperial County residents discover the experience of working with a team that truly cares and prioritizes long-term service.”
The new ownership team’s investment thesis centers on the significant organic growth opportunities available in the San Diego and Imperial County pest control and termite markets, two of the most active service categories in Southern California. The team also plans to modernize marketing and sales functions and pursue acquisitions of complementary companies serving the greater San Diego market.
