The total U.S. pest index increased 17 percent year-over-year in March, according to a report released by PCO M&A Specialists and William Blair.
This marks a strong acceleration from increases observed in January (up 5 percent) and February (up 6 percent). Some of this increase can be attributed to the COVID-19 pandemic’s effects on the market in March 2020, according to the researchers.
The index increased 21 percent on a sequential basis, which is higher than normal seasonal trend (up 10 percent in March 2020 and 16 percent in March 2019). This index includes recurring and nonrecurring revenue for residential pest, commercial pest and termite. It does not include residential door-to-door companies.
I would now like to turn the conference over to your host, Joe Calabrese.
