Pest Index Up 10 Percent YOY in May

The total U.S. William Blair/PCO Bookkeepers & M&A Specialists Pest Index increased 10 percent year-over-year in May 2024, compared with 12 percent growth in April and 8 percent growth in March.


The total U.S. William Blair/PCO Bookkeepers & M&A Specialists Pest Index increased 10 percent year-over-year in May 2024, compared with 12 percent growth in April and 8 percent growth in March. The long-term historical growth rate of the total pest index is 11 percent.

“The pest index decelerated slightly in May, following a strong rebound in April,” says William Blair Equity Researcher Tim Mulrooney, noting the deceleration was primarily driven by a slowdown in the commercial pest and termite indices (residential remained steady at 12 percent growth). “Despite the modest deceleration in May, we still characterize the overall pest market as healthy, showing continued growth that is essentially in line with the long-term historical industry average.”

Dan Gordon, managing member of PCO Bookkeepers & M&A Specialists, adds, “While we are seeing marketing costs rise, we are also seeing best-in-class companies pay the additional marketing costs in order to grow. As we move into the warmer months, we should see continued growth for the rest of the year.”

The month’s results by segment include:  

• The Residential Pest Index increased 12 percent year-over-year.
• The Commercial Pest Index increased 11 percent year-over-year.
• The Termite Index increased 6 percent year-over year.
• The Bed Bug Index increased 9 percent year-over-year.
• The Mosquito Index increased 9 percent year-over-year
