UF/IFAS Identification Tool Tracks the Spread of Invasive Termites for PMPs

University of Florida researchers caution the public that an increasing number of communities are now hot spots for invasive termite species, facing significant threats to property and trees.

“Recent studies indicate that Formosan subterranean termites, Asian subterranean termites and West Indian drywood termites are expanding their reach, posing an increasing threat to homeowners across the state,” said Thomas Chouvenc, associate professor of urban entomology at the UF/IFAS Fort Lauderdale Research and Education Center (FLREC) in Davie.

Chouvenc specializes in termite biology, ecology, evolution and pest control. To help Floridians stay ahead of termite infestations, scientists at the research center maintain a publicly accessible online termite distribution map that tracks the spread of termites in real time.

This interactive map is updated regularly by scientists at the center who receive species samples from property owners and certified pest control operators. The map provides property owners with valuable, up-to-date information on which termite species have been detected in a given neighborhood. Over the past few years, the Formosan subterranean termite has steadily spread to new counties, with infestations now documented in all major cities, said Chouvenc.

Meanwhile, the Asian subterranean termite, once confined to South Florida, has recently been detected in multiple cities in Central Florida, from Tampa to Melbourne, placing more communities at risk. The West Indian drywood termite remains a persistent and costly issue for homeowners throughout the state.

“All three invasive termite species present serious risks of structural damage over time, but not all communities are equally affected,” Chouvenc said. “As these pests continue to spread, it is crucial for homeowners to understand their local risk and take preventive measures.”

Each termite species requires a different approach to manage. Therefore, accurate identification of the species is essential before applying any treatment. To help property owners and pest control professionals, the UF/IFAS termite team offers a termite identification service.

While termites are active year-round, they swarm to mate and start new colonies in Florida between March and June, making this the time when property owners are most likely to see them.

With 20 different species in the state, staying vigilant is key. Researchers stress the importance of responding promptly at the first signs of termites, such as seeing dropped wings around moldings or windows and decayed wood, to prevent costly damage to properties and trees.

“If you live in a neighborhood with an established termite population of one of these invasive species, you can take proactive steps to minimize the risk of damage over time,” said Chouvenc. “A conversation with a certified pest control provider can help homeowners develop a long-term strategy to protect their property.”
