That figure traces to no primary source, not even in the university extension publications that print it. The best-sourced estimate is a 2012 review in *Annual Review of Entomology* by Rust and Su, which put the worldwide cost of termite control and repair near $40 billion a year, roughly half of that in the United States, with subterranean termites responsible for about 80 percent of it. That number was built backward from termiticide sales, multiplied by a repair-to-control ratio borrowed from Formosan termite work in New Orleans. Nobody has actually measured it. Treat it as an order of magnitude, not a measurement, and be skeptical of anyone who quotes you a damage total to the dollar.
