The William Blair/PCO Bookkeepers & M&A Specialists total U.S. Pest Index increased 12 percent year-over-year in December 2025, above the long-term average index growth rate of 10 percent.
“After normalizing for one more workday in December, the Pest Index increased about 8 percent year-over-year,” says William Blair Equity Researcher Tim Mulrooney. “This is slightly below the 10 percent rate of growth that the index averaged throughout 2025.”
Dan Gordon, managing member of PCO Bookkeepers & M&A Specialists, adds, “The December Pest Index results emphasize the underlying strength and resilience of the pest control industry. Even after adjusting for an extra workday, the industry grew at a pace near its long-term average, signaling healthy demand.”
The month’s results by segment include:
• The Residential Pest Index increased 15 percent year-over-year
• The Commercial Pest Index increased 9 percent year-over-year
• The Termite Index increased 6 percent year-over-year
• The Bed Bug Index increased 5 percent year-over-year
