Simple answer: no, termites do not go away on their own. A termite colony in Alexandria, Louisiana will keep feeding, growing, and reproducing until something stops it. Left untreated, a colony expands over time and causes progressively more structural damage—so waiting it out only makes the problem worse and the repairs more expensive.

If you’ve spotted mud tubes along your foundation or noticed a swarm near your windows, you might be hoping the problem sorts itself out. Maybe the swarmers vanished after a day or two, and the house went quiet again. That silence feels like good news.

It isn’t.

Termites don’t pack up and leave. They dig deeper, spread wider, and eat quietly behind your walls while you assume the threat has passed. In a climate like central Louisiana’s—warm, humid, and rich with the moisture termites crave—colonies thrive year-round. This post explains why the “they’ll leave on their own” myth is so dangerous, what really happens inside an untreated colony, and what you can do about it before the damage becomes visible.

Why do people think termites disappear on their own?

The myth usually starts with a swarm. Once or twice a year, mature colonies release winged reproductive termites called swarmers. These insects flood out, look alarming, then seem to vanish within hours or days.

Homeowners see the swarm end and assume the infestation ended with it. But the swarmers leaving isn’t a sign the colony is gone—it’s a sign the colony is healthy enough to reproduce. Most swarmers die quickly, yet the ones that survive pair off and start brand-new colonies nearby. Meanwhile, the original colony continues feeding under the surface, completely undisturbed.

Another reason the myth sticks: termites are nearly invisible. Subterranean termites, the most common type in Louisiana, live underground and travel through mud tubes to reach wood. You rarely see the workers doing the actual damage. No visible bugs feels like no problem—but silence is exactly how termites operate.

What actually happens inside an untreated termite colony?

An untreated colony doesn’t shrink or stall. It grows. A single subterranean termite colony can contain hundreds of thousands of members, and some mature colonies house more than a million termites. The queen can lay thousands of eggs per day, so the workforce eating your home keeps expanding.

Here’s the progression most Alexandria homeowners never see:

• Early stage: A small colony establishes near a food and moisture source, often under the foundation or in damp soil against the house.
• Growth stage: Workers build mud tubes to reach untreated wood and begin feeding on structural timber, joists, and subfloors.
• Mature stage: The colony produces swarmers, launches new satellite colonies, and accelerates the rate of damage as its population climbs.

The Formosan subterranean termite—an especially aggressive species well established across Louisiana—makes this worse. Formosan colonies grow larger and eat faster than native subterranean termites, and they’re notoriously difficult to eliminate once entrenched. Central Louisiana sits squarely within their range.

Why does central Louisiana make termite problems worse?

Termites need warmth, moisture, and wood. Alexandria delivers all three in abundance.

The region’s long, humid summers and mild winters mean termites stay active nearly year-round instead of slowing down in a hard freeze. Frequent rain keeps soil moist, which subterranean termites depend on to survive and travel. Add in the wood-framed construction common across Rapides Parish, and you have close to ideal conditions for colony growth.

This is why “waiting to see what happens” is riskier here than in drier or colder climates. A colony that might stay small elsewhere can expand rapidly in central Louisiana’s environment.

How much damage can termites cause if you wait?

Termites cause an estimated $5 billion in property damage across the United States every year, according to the National Pest Management Association. Standard homeowners insurance almost never covers it, because termite damage is considered preventable through maintenance.

The financial danger comes from how slowly and quietly the damage accumulates. A colony may feed for months or years before you notice sagging floors, hollow-sounding wood, or cracked paint. By then, the repair bill has grown alongside the colony. Structural repairs for advanced infestations can run into the thousands—far more than the cost of early treatment.

Delay works entirely in the termites’ favor. Every month an infestation goes untreated, the colony gets bigger, the damaged area gets wider, and the eventual cost climbs.

What are the warning signs of termites in your home?

Catching an infestation early saves money and structure. Watch for these signs:

• Mud tubes: Pencil-width tunnels of dried soil running up your foundation, walls, or crawl space piers.
• Swarmers or discarded wings: Winged termites indoors, or small piles of shed wings near windowsills and light sources.
• Hollow or damaged wood: Wood that sounds hollow when tapped, or blistered and darkened surfaces.
• Bubbling or cracked paint: Often mistaken for water damage, this can signal termite activity beneath the surface.
• Tight-fitting doors and windows: Warping from termite moisture and damage can make frames stick.

If you spot any of these, treat it as urgent. The colony behind them will not resolve on its own.

How do you actually get rid of a termite colony?

Because termites live hidden and reproduce fast, DIY sprays rarely reach the heart of the colony. Store-bought products may kill a few visible workers while leaving the queen and the underground population untouched—which is why the problem returns.

Effective control targets the whole colony, not just the termites you can see. Professional options generally fall into two categories:

Treatment type	How it works	Best for
Liquid termiticide barrier	A treated zone in the soil around and under the structure that kills termites on contact	Active infestations and immediate protection
Bait systems	Stations placed in the ground that colony members carry back to the nest, eliminating it over time	Long-term monitoring and colony elimination

Choose a liquid barrier if you need fast, comprehensive protection around an active infestation. Choose a bait system if you want ongoing monitoring and a lower-disruption approach that wipes out the colony gradually. Many homeowners combine both, guided by a licensed professional’s inspection.

A professional inspection also identifies the species involved—native subterranean versus Formosan—which changes the treatment strategy significantly.

The bottom line for Alexandria homeowners

Termites never go away on their own. A colony under your Alexandria home will keep growing and keep eating until a targeted treatment stops it. The quiet after a swarm isn’t relief—it’s the sound of the colony settling in for the long haul.

The smartest move is early action. If you’ve seen mud tubes, swarmers, or unexplained wood damage, schedule a professional inspection now, while the problem—and the repair cost—is still small. Waiting only feeds the colony.

Frequently asked questions

Will termites leave if I remove their food source?

No. Removing one piece of infested wood won’t eliminate a colony that lives underground and can reach other wood throughout your home. Termites simply shift to the next available food source while the colony keeps growing.

How long does it take termites to cause serious damage?

It varies by colony size and species, but noticeable structural damage often develops over months to a few years. Aggressive Formosan colonies can cause significant damage faster than native subterranean termites because they feed in larger numbers.

Are termites active year-round in Louisiana?

Largely, yes. Central Louisiana’s warm, humid climate and mild winters keep termites active nearly all year, unlike colder regions where activity slows during freezes. This gives colonies more time to grow and feed.

Can I get rid of termites myself?

DIY products rarely eliminate an entire colony because the queen and most of the population live hidden underground. Professional termite treatment—liquid barriers, bait systems, or both—targets the whole colony and is far more reliable.

Does homeowners insurance cover termite damage?

In most cases, no. Insurers typically classify termite damage as preventable through routine maintenance, so it’s excluded from standard policies. That makes early detection and treatment your best financial protection.
