The William Blair/PCO Bookkeepers & M&A Specialists total U.S. Pest Index increased 8 percent year-over-year in February 2026, below the long-term average index growth rate of 10 percent.
“This is the second month in a row that the index has hung below the long-term historical average,” says William Blair Equity Researcher Tim Mulrooney. “Several companies have reported disruptive weather patterns causing operational disruption and affecting pest activity to start the year.”
Dan Gordon, managing member of PCO Bookkeepers & M&A Specialists, adds, “Although this marks the second consecutive month of deceleration, it appears to be largely driven by disruptive weather. The fundamentals of the pest control market remain strong.”
The month’s results by segment include:
- The Residential Pest Index increased 11 percent year-over-year.
- The Commercial Pest Index increased 6 percent year-over-year.
- The Termite Index increased 5 percent year-over-year.
- The Bed Bug Index decreased 18 percent year-over-year.
