Seeing Termite Swarmers?

---

Few things alarm homeowners more than seeing winged termites suddenly appear around windows, doors, or light fixtures. These insects—called swarmers—are often the first visible sign that termites are nearby. However, what many people don’t realize is that termite damage usually begins long before swarmers are ever seen.

Swarmers are reproductive termites whose job is to leave an established colony and form new ones. They typically emerge in large numbers during warm, humid conditions—most commonly in Texas between March and April, though timing can vary.

Seeing swarmers does not mean termites just arrived. In most cases, it means:

• A mature colony already exists nearby
• The colony has reached a size capable of reproduction
• Feeding and damage have been occurring for some time
   

Subterranean termites feed on wood from the inside out, often hidden behind walls, under flooring, or within structural supports. Because they avoid light and open air, their activity can continue undetected for months or even years.

By the time swarmers appear:

• Wood damage may already be present
• Structural components may be weakened
• The infestation is no longer in its early stages
   

Swarm season doesn’t start the problem—it reveals it.

Swarmers are attracted to light and are often found:

• Near windows and sliding glass doors
• Around baseboards
• In bathtubs or sinks
• Near exterior doors or garages
   

After swarming, their wings are shed, which is why piles of discarded wings are another common warning sign.

While seeing swarmers can be unsettling, it’s also an important opportunity. Swarm season is often the moment homeowners finally realize there may be an underlying issue that needs attention.

Ignoring swarmers or assuming they’re harmless flying ants can allow damage to continue unnoticed.

If you see termite swarmers:

• Don’t assume the issue just started
• Don’t ignore it and hope it passes
• Understand that damage likely preceded what you’re seeing
   

Early inspections—especially before or at the start of swarm season—can help clarify what’s happening and prevent further damage.

Termite swarmers are a symptom, not the cause. By the time you see signs, termites have already been active in your home causing damage.

Understanding this helps homeowners respond thoughtfully rather than reactively—and reinforces why early awareness matters when it comes to termites in Texas.
