Termite Swarm Season Is Coming: What Georgia Homeowners Need to Know

Every year, starting as early as late February in northeast Georgia, homeowners begin calling pest control companies with the same report: “There are thousands of flying insects coming out of my floor/walls/window frames.” What they’re witnessing is a termite swarm, and while it looks alarming, understanding what’s actually happening helps you respond correctly.

What Is a Termite Swarm?

Subterranean termite colonies reproduce by producing “alates”, winged reproductive termites whose sole purpose is to leave the colony, find a mate, and start a new colony. When environmental conditions are right (warm temperatures, high humidity, often following a rain event), thousands of these alates emerge simultaneously.

This is called a swarm, and it typically lasts 30 minutes to an hour before the alates lose their wings and disperse. The swarmers you see are not the ones eating your house, they’re the reproductive caste, not the worker caste. But their presence tells you something critical: there is a mature termite colony somewhere on or near your property.

When Does Swarming Happen in Georgia?

Eastern subterranean termites, the most common species in northeast Georgia, typically swarm from February through April, with peak activity in March and early April. Swarms usually occur during daylight hours, 1-4 hours after a warm rain.

Formosan termites (less common but present in parts of Georgia) swarm at night in late spring, often around May and June.

Indoor vs. Outdoor Swarms, Why It Matters

Seeing swarmers outside near your home is concerning but not definitively diagnostic. Swarmers can travel hundreds of feet, so a swarm outside could be from a neighboring property. Watch for any that are specifically emerging from cracks in your foundation, from wood, or from the soil against your home.

Seeing swarmers inside your home, particularly large numbers of them emerging from the floor, walls, or window frames, is a much clearer sign that you have an active colony inside your structure. This warrants immediate action.

What to Do If You See a Swarm

1. Don’t panic. The swarmers themselves are not destructive, the damage is already being done by the workers you can’t see.
2. Don’t spray them with insecticide. Killing swarmers does nothing to address the underlying colony, and their dead bodies and shed wings are useful evidence.
3. Collect a few in a sealed bag, a pest professional can use them to confirm species.
4. Note where they’re emerging from, photograph it if possible. The emergence point is a clue to where the colony is.
5. Call a pest professional promptly. You don’t need to call at 6am during the swarm, but don’t wait weeks either.

What Happens After the Swarm

Most swarmers die within hours, they’re extremely vulnerable to desiccation (drying out). They need to find a mate and access to moist soil to survive. You’ll likely see their shed wings in piles along window sills and doorways. This is normal and can be vacuumed up.

What’s left is the same colony that was there before, still eating your home, more slowly and invisibly now that the dramatic swarm event is over.

The Cost of Waiting

Termite damage is cumulative. The longer a colony is present, the more structural wood it consumes. A colony discovered in its second year causes significantly less damage than one discovered in its fifth. Georgia homeowners who notice swarm signs but wait until “spring is over” to address it lose months of compounding damage.

The average termite treatment is a fraction of the cost of repairing termite-damaged structural wood.
