U.S. Pest Index for August indicates slow growth

The William Blair/PCO Bookkeepers & M&A Specialists total U.S. Pest Index increased 7 percent year-over-year in August 2026, below the long-term average index growth rate of 10 percent.

A result above 10 percent is a sign of strength for the month, and a reading below 10 percent is a sign of softness for the month.

“The past five months have been below the long-term average and there was no improvement in August,” William Blair Equity Researcher Tim Mulrooney said.

Dan Gordon, managing member of PCO Bookkeepers & M&A Specialists, added, “At this point, the data suggest that the industry is experiencing a sustained period of softer growth rather than a single-month fluctuation. We’ll be watching the next few months closely to see whether this is a temporary slowdown or the beginning of a longer-term shift in the industry’s growth rate.”

The month’s results by segment include:

• The Residential Pest Index increased 7 percent year-over-year.
• The Commercial Pest Index increased 10 percent year-over-year.
• The Termite Index increased 4 percent year-over-year.
• The Bed Bug Index was flat year-over-year.
• The Mosquito Index decreased 3 percent year-over-year.
