What Are Subterranean Termites?

Understanding the Enemy Beneath the Surface

Subterranean termites live in large colonies underground and build mud tunnels to reach their food sources, which are often your home’s wooden structures. They love warm, moist environments and usually enter buildings through cracks in foundations or gaps near pipes and utility lines.

Here’s what makes them so dangerous:

• They feed on anything containing cellulose, like timber, cardboard, and even paper.
  
• They can travel several metres underground without being seen.
  
• By the time damage is noticed, it’s often already serious.
  

These pests are silent destroyers, so early detection and prevention are your best weapons.

How Do Subterranean Termites Damage Homes?

Tiny Bugs, Huge Impact

Subterranean termites don’t just chew on wood—they weaken entire structures. They can:

• Eat away at support beams, floors, and walls
  
• Cause windows and doors to stick due to warping
  
• Create hollow-sounding wood
  
• Leave behind bubbling paint or soft spots in floors
  

In severe cases, termite damage may cost tens of thousands of dollars to repair and may not be covered by home insurance.

How to Prevent Subterranean Termite Infestations

Simple Steps to Make Your Property Less Attractive to Termites

🔒 1. Install Physical Termite Barriers

Physical barriers are installed during construction or renovations but can also be retrofitted in some cases. These include:

• Metal termite shields: Placed between your foundation and timber elements to block termite access.
  
• Crushed rock or sand barriers: Specially sized particles termites can’t crawl through.
  
• Stainless steel mesh: Fine mesh installed around pipes and foundations to keep termites out.
  
• Solid concrete slabs: A properly poured and maintained concrete base can stop termites from entering through the ground.
  

💧 2. Control Moisture Around the Property

Termites love moisture. Damp areas around or under your home make perfect homes for them. Here’s how to stay dry:

• Make sure your gutters are clean and downpipes direct water away from your house.
  
• Fix leaky taps, pipes, and air conditioning units quickly.
  
• Install vents in crawl spaces to keep air moving and reduce humidity.
  
• Use a moisture barrier under homes with raised floors.
  

🔍 3. Regular Property Inspections

The earlier you catch termite activity, the easier and cheaper it is to treat. Arrange a professional inspection:

• Once a year for most properties
  
• Twice a year in high-risk areas or if you’ve had termites before
  

A pest technician will check your subfloor, roof voids, walls, and garden areas for any signs of termite entry or damage. They’ll also point out risk areas like poor drainage, untreated wood, or mulch close to your home.

How to Spot Signs of Subterranean Termite Activity

Early Warning Signs That Mean Trouble

Even if you don’t see termites, look for these clues:

• Mud tubes on walls, foundations, or garden posts
  
• Hollow-sounding timber when tapped
  
• Warped floors or blistered paint
  
• Wings or droppings near windows or light fittings
  
• Noisy walls – a clicking sound may mean termites are communicating inside
  

If you spot any of these signs, call a professional immediately. The longer you wait, the more damage they’ll cause.

What to Do If You Have Subterranean Termites

Act Fast With These Proven Treatment Options

Once termites move in, they won’t leave on their own. You need to treat the infestation quickly and correctly.

🧪 1. Chemical Soil Treatments

This is one of the most common methods. A termite barrier is created by applying a long-lasting chemical treatment around the building’s perimeter.

• The treatment kills termites when they try to pass through.
  
• It may last several years with proper monitoring.
  
• Safe for families and pets when applied by licensed professionals.
  

🎯 2. Termite Baiting Systems

Bait stations are placed in the ground around your home.

• Termites take the bait and carry it back to the colony.
  
• It kills the entire colony, not just the termites you see.
  
• Good for ongoing protection and monitoring.
  

These are great for environmentally sensitive areas or where soil treatments aren’t possible.

🛠️ 3. Structural Repairs and Follow-Up

If termites have already caused damage, it’s important to repair affected areas:

• Replace rotted beams or flooring
  
• Seal all entry points
  
• Improve ventilation and drainage
  

Always work with a pest expert to ensure the damage is fully treated before you rebuild.
