Within the past 4 decades, the 2 invasive and destructive subterranean termites, Coptotermes formosanus Shiraki and Coptotermes gestroi (Wasmann), have established in and spread throughout Florida. Monitoring efforts, initiated in the early 1990s, have substantially expanded in the past decade, providing improved resolution of where the 2 species have increased their distribution, allowing for the determination of which communities are most at risk of infestation by either species. This study provides insights on the outcome of the "Florida Termite ID Services" program, which has involved a growing number of participating pest control companies across the state over the years. Thanks to this enhanced monitoring effort, there is now concrete evidence that the Formosan subterranean termite (C. formosanus) has established in most Florida coastal counties and within most large urban areas across the state. Contrary to initial expectations, the Asian subterranean termite (C. gestroi) has established in new localities beyond South Florida, where it was initially restricted, now impacts a growing number of communities. In South Florida specifically, the initial projection that 50% of the metropolitan area will likely be at risk of infestation by either termite species by ∼2040, remains valid. This study highlights the importance of monitoring the spread of these 2 invasive species in partnership with pest control providers, so as to continue to bring awareness of the growing termite risks to exposed communities.
