Cold Weather, Hot Threat: Formosan Termites in the Lowcountry This Winter

When you think of termites, you might picture swarms of these destructive pests emerging in the spring or summer. But in the Lowcountry, Formosan termites are a year-round threat that homeowners can't afford to ignore—even during the cooler winter months. Their persistence, adaptability, and voracious appetites make them a formidable opponent for anyone looking to protect their property.

What are Formosan termites?

Formosan termites are an invasive species of subterranean termites, often referred to as "super termites" because of their ability to cause significant damage in a short amount of time. Unlike other termite species, Formosans are more aggressive and can create larger colonies, which means they consume wood and other materials at an alarming rate.

Why are they active in winter?

While many pests slow down in the colder months, Formosan termites remain active underground or inside your home. Thanks to the warmer climates of the Lowcountry, combined with the insulation provided by houses, they can continue foraging and feeding throughout winter. Any untreated or infested wood within your property can become a prime target during this time.

Signs of Formosan Termite Activity

Detecting a Formosan termite infestation early can save you thousands of dollars in repairs. Here are some common signs to watch for:

  • Mud tubes: Termites create these pencil-width tubes to travel between their colonies and food sources.

  • Hollow-sounding wood: Tap on wooden surfaces; if they sound hollow, termites might be inside.

  • Blistered wood or peeling paint: Termites can create damage that resembles water damage.

  • Discarded wings: You may find piles of wings near windows or doors from termite swarms earlier in the year.

How to Protect Your Home This Winter

To prevent Formosan termites from wreaking havoc on your home, follow these essential tips:

  1. Inspect and seal entry points: Check for cracks in your foundation, gaps around pipes, or damaged screens where termites might enter.

  2. Eliminate wood-to-soil contact: Store firewood away from your home and ensure wood siding or decking doesn't touch the ground.

  3. Address moisture issues: Fix leaks, clean gutters, and maintain proper drainage to keep areas dry.

  4. Schedule a professional inspection: The best way to safeguard your home is to have the experienced professionals at Hilton Head Exterminators assess and treat it for potential threats.
