Pest Index Up 10% YOY in October

The total U.S. William Blair/PCO Bookkeepers & M&A Specialists Pest Index increased 10% year-over-year in October 2025, in line with the long-term average index growth rate of 10%.

“Revenue growth decelerated in the residential business, from 17% in September to 12% in October,” said William Blair Equity Researcher Tim Mulrooney. “However, adjusting for one more workday in September, we estimate that revenue growth in the residential business was similar across both months.”

“October’s results reflect business as usual in the U.S. pest control market — showing predictable demand and steady growth,” said Dan Gordon, managing member of PCO Bookkeepers & M&A Specialists. 

The month’s results by segment include:

• The Residential Pest Index increased 12% year-over-year.
• The Commercial Pest Index increased 8% year-over-year.
• The Termite Index increased 5% year-over-year.
• The Bed Bug Index increased 6% year-over-year.
• The Mosquito Index increased 16% year-over-year.
