Florida's Silent Destroyers: Two Termite Species Spread Unchecked Across the State

Two aggressive termite species are spreading rapidly across Florida, causing millions in structural damage each year. The Asian subterranean termite and the Formosan subterranean termite have both taken hold in the state, threatening homes and buildings. Experts warn that early detection is difficult, as these pests live underground until significant harm is already done.

The Formosan subterranean termite first appeared in Florida during the 1980s. Decades later, the Asian subterranean termite was detected in Dade County in 1996. It spread quickly through infested shipping pallets, reaching Broward, Palm Beach, and Miami-Dade Counties by the 2000s. By 2010, annual damage costs ran into the millions, with urban areas like Miami, Fort Lauderdale, and West Palm Beach hit hardest.

In recent years, the Asian subterranean termite has expanded further, reaching Tampa and Orlando. It now outcompetes native species and affects over 20% more structures, according to USDA reports. Meanwhile, the University of Florida Termite Collection has confirmed Formosan subterranean termite samples on the West Coast, including Tampa.

Both species thrive underground, making early detection a challenge. Homeowners are advised to take preventive steps, such as moving wood piles away from houses and trimming branches that touch buildings. Regular inspections by pest control professionals can also help identify infestations before severe damage occurs.

Scientists encourage residents to send termite samples for analysis. This helps track the spread of these invasive pests across the state.

Florida now hosts over 20 termite species, but the Asian and Formosan subterranean varieties remain the most destructive. Their rapid expansion continues to threaten structures, with millions spent annually on repairs. Preventive measures and professional inspections remain key to limiting further damage.
