What Every Homeowner Needs to Know About Subterranean Termites

​

Your home is likely your biggest investment. You protect it from storms, lock the doors against intruders, and keep up with your regular property maintenance. But right now, beneath the soil of your backyard, a tiny, organized army could be marching toward your foundation.

 

Meet the subterranean termite.​ Often called "silent destroyers," these pests cause massive structural

damage every year, usually before homeowners even realize they are there. Here is a look at what

subterranean termites are, how to spot the warning signs, and how to properly protect your property from

these underground invaders.

​

What are Subterranean Termites?

​

Subterranean termites live in the soil. Unlike other wood-boring pests, they require constant, high levels of moisture to survive. Because of this, they build their primary colonies deep underground and travel back and forth to their food source—the cellulose-rich wood in your home.

​

Because they require a damp environment, they are highly dependent on the ground, making your home’s foundation their primary point of entry.

​

The Caste System

​

A single subterranean termite colony can contain hundreds of thousands of members, divided into distinct roles:

​

• The Queen and King: The reproductive heart of the colony, responsible for its continuous growth.

• Workers: The blind, wingless termites that do the actual damage. They forage for food 24/7 to feed the rest of the colony, chewing through structural wood along the grain.

• Soldiers: The defenders of the colony, equipped with large jaws to fight off ants and other underground invaders.

• Swarmers (Alates): Winged reproductives that leave the colony during specific seasons to mate and start new underground nests.​

 

Red Flags: How to Spot a Subterranean Infestation

​

Because they work from the inside out and travel underground, subterranean termites can chew through support beams for a long time without breaking the surface wood. However, they do leave behind a few telltale clues:

​

• Mud Tubes: This is the most definite sign of a subterranean infestation. Because these termites dry out quickly when exposed to the air, they construct pencil-sized tubes made of mud, soil, and saliva to travel safely from the earth up into your structure. Look for these on foundation walls, piers, slabs, and baseboards.

• Termite Swarmers or Discarded Wings: During peak swarming seasons (often triggered by rain and warm weather), winged swarmers leave their underground nests to breed. If you see a brief cloud of flying insects inside or right outside your home—or if you find piles of small, translucent, equal-sized wings on windowsills or floors—you have a mature colony nearby.

• Hollow-Sounding Wood: Subterranean termites eat the soft wood along the grain, packing their feeding galleries with a characteristic mud-and-liquid mixture. If you tap on a baseboard, door frame, or structural beam and it sounds hollow or papery, they may have already gutted the interior.

• Blistering Paint: As termites tunnel close to the surface, they trap moisture behind walls. This can cause paint to bubble, blister, or mimic water damage.​

​

Why DIY Sprays Don't Work

​

If you find mud tubes or active termites, do not spray them with store-bought chemicals.

Breaking a mud tube or spraying the termites you can see will disrupt their immediate pheromone trail and kill those individual insects, but it will not stop the colony. Subterranean termites live deep underground.

 

When disrupted by amateur treatments, the colony will simply seal off that area, retreat into the soil, and find another, more hidden route into your home to continue chewing through your investment.  ​To eliminate subterranean termites completely, you have to eliminate the subterranean network and the queen.

How We Protect Your Property

​

At Green’s Exterminating & Fencing Inc., we don't believe in temporary fixes. Backed by decades of

industry experience since 2000, we strictly adhere to advanced industry standards to deliver long-term

protection against subterranean threats. Because of this commitment to true, lasting protection, we reject outdated methods that fail under pressure, focusing instead on the critical science of how termite treatments actually work.

The Danger of Outdated Repellent Barriers

​

In Barbados, even today, many homeowners have their homes  treated for termite control using repellent termiticides, such as those with the active ingredients cypermethrin or permethrin, in the hope that subterranean termites would not gain entrance into their homes.

 

However, this approach has a critical flaw: subterranean termites have the ability to detect any repellent termiticide, and will relentlessly search the perimeter until they find a single gap—caused by shifting soil, roots, or weathering—to exploit and enter your property.

​

The real danger of these cypermethrin-based products is often only realized after severe damage has already taken place. if your property is already infested. A repellent termiticide introduces a severe risk by trapping active termites inside the structure. When cut off from their main ground colony, these resilient pests will adapt by establishing secondary nests within hidden areas of the property, utilizing localized moisture, and multiplying under the direction of supplementary queens. Instead of solving the problem, a repellent can inadvertently seal the destruction inside your home

 

The Power of Modern Non-Repellent Zones

​

To ensure complete property protection, modern industry standards utilize undetectable, non-repellent termiticides—such as advanced products utilizing Imidacloprid as the active ingredient.  Because termites cannot smell, taste, or see the termiticide, they travel through the treated zone completely unaware. Rather than acting as a temporary fence, this method capitalizes on the termites’ natural biology and social habits.

​

As they pass through on their 24/7 journey from their colonies to your home in search of cellulose, they pick up the imidacloprid on their bodies and freely transfer it to the rest of the colony through grooming and feeding behaviors. This is called the "transfer effect". It ensures the entire colony and its nests are thoroughly managed and neutralized—whether the termites are deep in the ground or hidden within your walls.
