Formosan subterranean termites are difficult to control. For that reason, prevention should be the first line of defense. If a Formosan colony is found within a structure, quick action is required to minimize potential structural damage. It is important to note that Formosan termites are not commonly found in Georgia, and most cases that have been identified here involve importing them in infested railroad ties from other states like Louisiana and Mississippi. When the soil of an infested structure is treated to stop their entry, the termites already in the structure may form an independent nest above ground and avoid the treated soil.
