The total U.S. William Blair/PCO Bookkeepers & M&A Specialists Pest Index increased 12 percent year-over-year in April 2024, up from 8 percent growth in March. The long-term historical growth rate of the total pest index is 11 percent.
“The pest index rebounded in April,” says William Blair Equity Researcher Tim Mulrooney. “The residential and commercial pest indices accelerated slightly during the month, but most of the outperformance was driven by the smaller indices, including termite, bed bug, and mosquito, all of which rebounded materially in April. Much of this acceleration was driven by the termite index, which increased 10 percent year-over-year in April, up from flat year-over-year performance in March. Although March was weaker than expected, the data suggests that termite-related service revenue caught up in April.”
Dan Gordon, managing member of PCO Bookkeepers & M&A Specialists, adds, “The index seems to have snapped back for April with a strong beginning to termite season. March appears to have been an anomaly, most likely created by bad weather.”
