Homeowners across coastal South Carolina are facing an increasing risk of Formosan termites in the Lowcountry, often referred to as “super termites” for their aggressive nature and destructive power. Unlike native termite species, Formosan termites form massive colonies, reproduce quickly, and can cause extensive structural damage in a short amount of time, sometimes before homeowners even realize there’s a problem.
What Are Formosan Termites?
Formosan termites are an invasive subterranean termite species originally from East Asia. Over time, they’ve spread throughout the southeastern United States, thriving in warm, humid climates like the Lowcountry. These termites are larger than native species and are known for their relentless appetite for wood, paper, insulation, and even some soft metals.

Why Are They Called “Super Termites?”
The nickname isn’t an exaggeration. Formosan termite colonies can contain millions of termites, compared to the thousands typically found in native colonies. Because of their size and organization, they can chew through wood at an alarming rate, compromising structural integrity far faster than other termite species.
Why the Lowcountry Is Especially Vulnerable
The Lowcountry’s coastal climate creates ideal conditions for Formosan termites. Mild winters, high humidity, frequent rainfall, and dense development all contribute to their spread. Older homes, crawl spaces, and properties with excess moisture are particularly at risk. Once established, these termites can remain active year-round.
Signs of a Formosan Termite Infestation
Formosan termites often remain hidden, but there are warning signs homeowners should watch for:
Mud tubes on foundations, walls, or crawl spaces
Swarms of winged termites (often at night, attracted to lights)
Hollow-sounding or damaged wood
Buckling floors or unexplained cracks in drywall
Because they work quickly and silently, early detection is critical.
Why Professional Termite Control Matters
DIY treatments are rarely effective against Formosan termites due to the size and depth of their colonies. Professional termite control uses advanced detection methods and targeted treatments designed to eliminate colonies at the source and protect your home long-term. Preventative inspections are especially important in high-risk areas like the Lowcountry
