Pest Index Up 14% YOY in September

The total U.S. William Blair/PCO Bookkeepers & M&A Specialists Pest Index increased 14% year-over-year in September 2025, above the long-term average index growth rate of 10%.

After normalizing for one more workday in September, the Pest Index increased about 9% year-over-year. This level is near the year-to-date growth rate of 10%.

“Despite concerns around consumer confidence, slowing job growth and the government shutdown, the health of the pest control consumer remains robust,” said William Blair Equity Researcher Tim Mulrooney. “This is a testament to the high recurring revenue model and nondiscretionary nature of the service.”
