The total U.S. William Blair/PCO Bookkeepers & M&A Specialists Pest Index increased 9 percent year-over-year in September 2024, accelerating modestly from the 7 percent result in August. The September results are just below the long-term average index growth rate of 10 percent.
“After normalizing for workday noise in July and August, index performance in recent months has essentially been in line with the long-term historical average,” says William Blair Equity Researcher Tim Mulrooney. “This suggests that the U.S pest control market is also growing in line with the long-term historical average of 4 percent to 5 percent.”
Dan Gordon, managing member of PCO Bookkeepers & M&A Specialists, adds, “This growth number is exciting especially given the nervousness about the economy pre-election. It will be interesting to see where the number stands in the future given the results of the election.”
The month’s results by segment include:
- The Residential Pest Index increased 7 percent year-over-year.
- The Commercial Pest Index increased 14 percent year-over-year.
- The Termite Index increased 7 percent year-over year.
- The Bed Bug Index increased 4 percent year-over-year.
