April Swarms: How to Spot Formosan Termites in Savannah, GA Before They Cause Damage
As Savannah shakes off the last chill of winter and begins to welcome spring’s warmer temperatures, something else starts to wake up—Formosan termites. Known for their aggressive nature and large colony sizes, these destructive pests begin their swarming season in April, and local homeowners should be on high alert.
What Are Formosan Termites?
Often referred to as “super termites,” Formosan termites are a highly invasive species that originated in East Asia but have established a strong presence in the southeastern U.S., including right here in Savannah. Unlike native subterranean termites, Formosan termites build enormous colonies with millions of members and can cause extensive damage to structures in a relatively short time.
Why April?
Formosan termites become active as temperatures rise, and April typically marks the start of their annual swarming season. Swarming is when the winged reproductive termites leave their existing colonies to form new ones. These swarmers are drawn to light and are often found near windows, doors, and outdoor lighting at dusk. Spotting them is a clear sign that a colony is nearby—and possibly already causing damage.
Signs of Formosan Termite Activity
Here are a few indicators to watch for in and around your home this spring:
Swarming termites: Winged termites appearing in large numbers, especially in the evening.
Discarded wings: Piles of shed wings near windowsills or light fixtures.
Mud tubes: Small tunnels made of soil and saliva, usually along foundation walls or crawlspaces.
Hollow-sounding wood: Wood that sounds empty when tapped may already be compromised.
Blistered or bubbling paint: Moisture buildup caused by termite activity can lead to damaged finishes.
Why They’re a Serious Threat
Formosan termites are capable of chewing through wood, flooring, and even wallpaper—silently and quickly. A single mature colony can consume up to one pound of wood per day, and since these pests typically operate out of sight, damage can go unnoticed until it’s severe.
How to Protect Your Home
The best defense against Formosan termites is a proactive one. Here are a few preventative tips:
Eliminate sources of excess moisture around your home.
Keep mulch and woodpiles at least 15 feet away from the foundation.
Seal cracks and crevices in your home's exterior.
Schedule an annual termite inspection with a trusted pest control professional.
