Pest Index Increased 9 Percent YOY in January

The total U.S. William Blair/PCO Bookkeepers & M&A Specialists Pest Index increased 9 percent year-over-year in January 2025, decelerating from December’s 11 percent result. The January result is slightly below the long-term average pest index growth rate of 10 percent.

“Based on commentary from several regional operators, we believe weather may have negatively affected January performance in some markets,” says William Blair Equity Researcher Tim Mulrooney. “On a sequential basis, the index increased 4 percent from January, which is in line with normal seasonal trends.”

Dan Gordon, managing member of PCO Bookkeepers & M&A Specialists, said, “The January result reflects continued resiliency in our market. It will be interesting to see if economic news in subsequent months changes anything. In any case, we know the pest control industry is consistent over the long haul.”
