Florida's silent invaders: Two destructive termite species spread unseen

Two aggressive termite species are spreading across Florida, raising concerns for homeowners and scientists. The Asian subterranean termite and the Formosan subterranean termite have been detected in new areas, including Tampa. Both species pose a threat to buildings due to their ability to cause hidden structural damage.

Meanwhile, another invasive pest—the Asian needle ant—has expanded far beyond Florida since its arrival in 1990. It now dominates parts of the southeastern US, displacing native species and forming dense colonies in cities and natural areas.

The Formosan subterranean termite first appeared in Florida during the 1980s, followed by the Asian subterranean termite in the 1990s. These termites live underground, making them hard to spot until damage becomes severe. Recent samples sent to the University of Florida Termite Collection confirm their spread along the West Coast, including Tampa.

Florida already hosts over 20 termite species, both native and invasive. To limit further damage, experts recommend regular inspections by pest control professionals. Homeowners are also advised to store firewood away from houses and trim branches that touch buildings.

The Asian needle ant, first found in Florida in 1990, has since spread to Georgia, South Carolina, and North Carolina. Data shows it is now one of North America's most invasive ant species. Its rapid expansion has pushed out native ants while establishing large colonies in urban and wild environments.

Scientists continue to monitor termite samples to track their movement across Florida. Early detection and preventive steps remain critical to reducing structural harm. The Asian needle ant's growth also highlights the broader challenge of invasive species displacing local wildlife.
