Protect your biggest investment with a professionally installed termite barrier. We use industry-leading products like Termidor HE to create an unbreakable line of defence around your Brisbane home.
A termite barrier in Brisbane is the most reliable way to protect your home from the devastating damage caused by subterranean termites. Brisbane's warm, humid subtropical climate creates ideal conditions for termite activity year-round, which is why more than 1 in 3 unprotected homes in South East Queensland will experience termite attack at some point.
At We Kill Termites, we've installed over 1,500 termite barriers across Brisbane, North Lakes, Moreton Bay, and the surrounding regions since 2019. Our licensed technicians specialise in chemical termite barriers, physical barriers, and reticulation systems tailored to your property's unique requirements.
A termite barrier is a continuous treated zone installed around the perimeter and sub-floor of your home designed to either kill or repel termites before they can enter your property. Unlike baiting systems that target existing colonies, barriers provide a proactive line of defence that works 24/7, 365 days a year.
There are two main categories of termite protection in Brisbane:
The right barrier for your home depends on whether you're building new, renovating, or protecting an existing property. Both types comply with Australian Standard AS 3660 when installed by a licensed professional.
A chemical termite barrier involves applying a non-repellent termiticide to the soil around your home's perimeter and beneath the slab or sub-floor. The most effective product available in Australia is Termidor HE (High Efficiency), which uses patented BASF technology to create a continuous treated zone with superior soil binding.
What makes a Termidor barrier in Brisbane so effective is its Transfer Effect. When termites pass through the treated zone, they don't die immediately. Instead, they carry the active ingredient (fipronil) back to the colony, spreading it through grooming and social contact. This chain reaction can eliminate an entire colony, not just the foragers that contact the barrier.
Key advantages of Termidor HE chemical barriers:
Physical barriers are manufactured materials installed during the construction phase of a new home. They create a continuous barrier that termites physically cannot pass through. The two most common systems used in Brisbane are:
Physical barriers are required under AS 3660.1 for all new residential construction in Queensland. They are a one-time installation that provides long-term protection without the need for chemical reapplication.
A reticulation system consists of a network of perforated pipes installed in the soil around your home's perimeter. These pipes allow a termiticide to be reapplied without excavation or drilling, making future top-ups faster, cheaper, and less disruptive.
Reticulation systems are ideal for:
The cost of a termite barrier installation in Brisbane depends on several factors including your home's size, construction type, soil conditions, and the barrier system chosen. Here's a general guide:
While a termite barrier is an investment, the cost of not having one can be catastrophic. Termite damage to a Brisbane home averages $10,000 to $50,000+ in repairs and is not covered by standard home insurance. A barrier pays for itself many times over.

We offer a full range of termite barrier systems to suit every Brisbane property, from new builds to established homes.
Termidor HE applied to soil around your home's perimeter. The most popular and effective option for existing Brisbane homes.
Manufactured sheeting and granular systems installed during construction for long-term physical termite exclusion.
In-ground pipe network allowing easy chemical reapplication without excavation. The most convenient long-term solution.
The best barrier depends on your property type, construction stage, and budget. Here's a quick comparison.
| Factor | Chemical Barrier | Physical Barrier | Reticulation |
|---|---|---|---|
| Best For | Existing homes | New builds | Both |
| Lifespan | Up to 8 years | 25+ years (structural) | Renewable (pipes last 25+ yrs) |
| Kills Termites? | Yes (colony elimination) | No (exclusion only) | Yes (chemical fill) |
| Installation Time | 1 day | Staged during build | 1-2 days |
| Starting Price | $2,000 | $2,500 | $3,000 |
| Maintenance | Reapply every 8 years | Annual inspection | Top-up every 5-8 years |
For established Brisbane homes, a Termidor HE chemical barrier is the most practical and effective solution. It can be installed in a single day with minimal disruption, and the Transfer Effect means it doesn't just block termites — it eliminates them.
If your home already has a reticulation system from a previous treatment, we can refill it with fresh termiticide at a significantly lower cost than a full new barrier.
Queensland building regulations require a termite management system compliant with AS 3660.1 for all new residential construction. Physical barriers like Kordon or Granitgard are typically installed during the slab and frame stages.
Many builders and homeowners choose to combine a physical barrier with a reticulation system for the ultimate in long-term, renewable protection. We work directly with builders across Brisbane to ensure compliance and quality.
From initial assessment to final certification, we follow a proven 4-step process to ensure your barrier is installed to the highest standard.
A licensed technician inspects your property to assess construction type, soil conditions, risk factors, and access. This is always free and obligation-free.
We recommend the most effective and cost-efficient barrier system for your property, explain your options clearly, and provide a fixed-price written quote.
Our licensed team installs your barrier to manufacturer specifications and in full compliance with AS 3660. Most chemical barriers are completed in a single day.
You receive a formal certificate of installation, manufacturer warranty documentation, and a recommended maintenance schedule to keep your barrier effective.
Everything Brisbane homeowners need to know about termite barrier installation, costs, and maintenance.
Termite barrier installation in Brisbane typically costs between $2,000 and $5,000+ depending on the type of barrier, the size of your home, soil conditions, and accessibility. Chemical barriers using Termidor HE generally range from $2,000 to $4,000 for an average-sized home, while physical barriers for new builds can range from $2,500 to $5,000+. We provide free, no-obligation quotes tailored to your property.
A chemical termite barrier using Termidor HE typically lasts up to 8 years when professionally installed. The longevity depends on soil type, drainage conditions, and environmental factors specific to Brisbane's subtropical climate. We recommend annual termite inspections to ensure your barrier remains effective throughout its lifespan.
For existing Brisbane homes, Termidor HE chemical barriers are the gold standard due to their proven effectiveness and Transfer Effect technology that eliminates entire colonies. For new builds, physical barriers like Kordon or Granitgard are often required under Australian Standard AS 3660.1. Many Brisbane homeowners opt for a combination of both for maximum protection.
Baiting systems and termite barriers serve different purposes and can complement each other. Baiting systems monitor and eliminate active colonies, while barriers create a continuous treated zone around your home that kills or repels termites attempting to enter. In high-risk areas of Brisbane, many pest professionals recommend both for comprehensive protection.
Yes. Under the Building Code of Australia and Australian Standard AS 3660.1, all new residential buildings in Queensland must have a termite management system installed during construction. This can be a physical barrier (such as Kordon or Granitgard), a chemical barrier, or a combination. Your builder is required to provide documentation of the system installed.
Chemical termite barrier installation for an average Brisbane home typically takes one day (4-8 hours) depending on the property size, soil conditions, and access points. Physical barrier installation during new construction is staged across the build process. Our team will provide you with a clear timeline during the free site assessment.
