Are Formosan Termites in North Carolina?

Formosan termites were first identified in North Carolina in Brunswick County in 1992. Other infestations have since been reported in Rutherford County.

To help determine the species’ spread and appropriate control measures, the North Carolina State University Department of Entomology and the North Carolina Department of Agriculture and Consumer Services joined to form the North Carolina Formosan Termite Program. Volunteers conducted a field survey in Rutherfordton, Ruth, Spindale and Forest City, N.C., in 2003 and a light trap survey in 2004. In 2004, the program began control measures on public land, including the installation of termite bait systems in infested areas – namely, along railroad tracks – and termiticide treatment for infested trees.

More Information about Termites in North Carolina

According to Termite Infestation Probability Zones (TIP Zones), North Carolina is located in TIP Zone #2 (moderate to heavy), which means the potential for termite damage is considered significant. Areas with higher probabilities for termite activity require more termite control measures to meet International Residential Code building standards for new homes than areas with less frequent activity.

In states like North Carolina where termites are active and widespread, it is essential to maintain an effective termite prevention and control program.
