Pest Index Increased 9% YOY in July

The total U.S. William Blair/PCO Bookkeepers & M&A Specialists Pest Index increased 9 percent year-over-year in July 2025, slightly below the long-term average index growth rate of 10 percent.

The pest index accelerated in July, compared to 7 percent growth in June (on a workday-adjusted basis).

“Despite the better July result, the Pest Index is still running slightly below the long-term historical average,” William Blair Equity Researcher Tim Mulrooney said. “This may be due to continued headwinds in digital leads. We believe a more sophisticated approach to digital marketing will be necessary to drive leads in the rapidly evolving landscape of generative AI.”

Dan Gordon, managing member of PCO Bookkeepers & M&A Specialists, said, “The U.S. economy overall showed mixed signals in July. An accelerating Pest Index that’s just slightly below the long-term average index growth rate indicates the industry remains resilient.”

· The Residential Pest Index increased 12 percent year-over-year.
· The Commercial Pest Index increased 8 percent year-over-year.
