Termite Swarm Season Hits Nashville, Lewisburg & Lebanon: What You Need to Know to Protect Your Home

Spring is in the air—and so are termites. Every April, as Middle Tennessee warms up and humidity increases, termite swarm season begins in full force. If you’re seeing winged insects around your doors or windows, you might be facing more than a few nuisance bugs. You could be dealing with a serious structural threat to your home.

Google searches are spiking for:

• “Flying termites or ants”

• “Termite swarms in Tennessee”

• “Termite inspection cost”

That’s because across Nashville, Lewisburg, and Lebanon, Eastern subterranean termites are on the move—and they don’t just fly by. They set up colonies and quietly feed on wood, often undetected until thousands of dollars in damage has already been done.

What the Experts Say About Tennessee’s Termite Risk

“Eastern subterranean termites can cause significant damage long before they’re detected. Swarmers are often the first visible sign of an established colony.”
— UT Extension Entomology Program

Nashville’s mix of old homes, wet crawl spaces, and untreated wood-to-soil contact makes it a prime target for these destructive pests. Swarmers—those winged termites you’re seeing—are sent out to start new colonies, meaning the damage is already happening underground or behind your walls.

Field Insight: What Lookout Pest Control Is Seeing Right Now

“If you’re seeing winged termites, it means they’ve been active below your home for a while—it’s time to act fast.”
— Rachel M., Termite Specialist, Lookout Pest Control

This spring, Lookout Pest Control has seen a 30% uptick in termite inspection requests across Davidson, Marshall, and Wilson Counties. Many of these swarmers are emerging from untreated crawl spaces or soil near the home’s foundation.

In Lewisburg, we’re responding to a high number of swarm calls near woodpile storage areas and wooden deck posts. In Lebanon, older brick homes with wooden additions are especially vulnerable due to hidden structural contact with moist soil.

How Lookout Protects Homes During Swarm Season

Our termite experts use a comprehensive detection and treatment strategy built for Tennessee’s climate and home styles. Whether you have a slab foundation in Nashville or a crawl space in Lewisburg, we tailor our approach to eliminate active infestations and prevent future ones.

Step 1: Thermal and Visual Inspection

We use thermal imaging and moisture meters to locate hidden activity in walls, floors, and crawl spaces—areas termites love.

Step 2: Treatment Options Based on Structure

• Sentricon® Baiting Systems: Ideal for long-term colony elimination and monitoring, especially near gardens and foundations.

• Liquid Termiticide Barrier: Applied along the perimeter and key access points for immediate knockdown and prevention.

Step 3: Crawl Space Fortification

If termites were found in or near your crawl space, we’ll recommend wood treatment, moisture control, and encapsulation options to keep them from returning.

Homeowner Tips to Prevent Termite Infestations

Here are a few termite-prevention steps you can take today to reduce your risk this spring:

1. Remove Wood-to-Soil Contact

Termites love untreated wood that directly touches the ground. Use concrete blocks or metal barriers to lift firewood, deck posts, and garden timbers off the soil.

2. Keep Mulch Away From the Foundation

Avoid piling mulch or wood chips too close to your home. Maintain at least 12 inches of clearance to reduce moisture and concealment opportunities.

3. Schedule an Annual Termite Inspection

Most termite infestations are missed for years. A professional inspection is the only reliable way to detect early signs and avoid serious structural damage.

4. Control Moisture

Fix leaky pipes and ensure crawl spaces are well-ventilated or encapsulated. Moisture attracts termites and helps their colonies thrive.

Don’t Wait Until the Damage Is Visible

Most homeowners don’t discover a termite issue until they’re replacing floors, repairing framing, or selling their home. The earlier you act, the more you save.
