What Is A Termite Treatment?
TL;DR — Quick Answer
Termite treatment is the process of eliminating active colonies and setting up defences to stop future infestations. In Australia, termites cause over $1.5 billion in damage annually, with Sydney’s warm, humid climate making it one of the highest‑risk areas
What is the risk of not having a termite treatment?
Without treatment, colonies can grow to over 1 million insects, eating through floorboards, walls, and foundations. The goal is not just to kill what you see, but to protect the whole structure long‑term.
Effective termite treatment combines barriers, baiting, and ongoing monitoring. AEPMA data shows professional methods are 92% successful, while DIY works only 25–35% of the time. Costs range from $100 for products to $6,500 for full barriers, but treatment costs just 10–15% of what structural repairs would cost.

What Are the Different Types of Termite Treatment?
There are several proven methods used in NSW. Each works differently and suits different property types and infestation levels:
Chemical Barriers
Liquid termiticides are applied to the soil around the foundation. They create a continuous treated zone that kills or repels termites before they reach timber. CSIRO confirms these last 5–8 years when applied correctly.
Termite Baiting Systems
Stations are placed in the ground every 2–3 metres around the home. Termites feed on the bait and carry it back to the colony, eliminating the whole group over time. Ideal for homes where soil treatment is difficult.
Physical Barriers
Non‑chemical options like stainless steel mesh or graded granite particles block termites physically. They are installed during construction or retrofitted and can last the lifetime of the building.
Termite Dusting & Foam
Dust or foam is injected directly into tunnels, wall cavities, or nests. It sticks to termites and spreads through the colony. Best used alongside other treatments for hidden infestations.
How Much Does Termite Treatment Cost in Sydney?
Prices depend on property size, infestation severity, and method chosen. Below is the average pricing for 2026:
| Treatment Type | Average Cost Range | Expected Lifespan |
|---|---|---|
| DIY Products | $100 – $300 | Days to months |
| Chemical Barriers | $3,500 – $6,500 | 5 – 8 years |
| Baiting Systems | $1,800 – $3,500 + annual checks/inspections | Ongoing with maintenance |
| Full Fumigation | $3,500 – $6,500 | Annual Inspections required |
While professional costs seem higher upfront, the Master Builders Association of NSW reports that average repair costs for termite damage start at $10,000 and can exceed $100,000 — making treatment a far better investment.
DIY vs Professional Termite Treatment: Which Works Better?
Many homeowners try DIY first, but there are clear differences in results and safety:
| Factor | DIY Treatment | Professional Treatment |
|---|---|---|
| Success Rate | 25 – 35% | 90 – 95% |
| Coverage | Only visible areas | Full soil, sub‑floor, and wall cavities |
| Regulatory Compliance | May not meet AS 3660 | APVMA approved, insurance‑accepted reports |
| Guarantee | None | 3 months to 8 years warranty |
| Time & Effort | Ongoing application/monitoring | One application + scheduled checks |
Common DIY methods include orange oil, borax, vinegar, and diatomaceous earth. These can repel or kill termites on the surface, but rarely reach hidden colonies or stop them from coming back.
If you have found mud tubes, hollow wood, or swarming termites, do not rely only on store‑bought products. Call our team at 1800 819 189 for an accurate assessment.

How to Prevent Termites After Treatment
Treatment works best when combined with good maintenance. Follow these steps to keep your home protected:
- Repair leaking pipes, taps, and roofs to reduce moisture.
- Keep wood, mulch, and garden debris at least 30cm away from walls.
- Seal cracks in concrete, brickwork, and around pipes.
- Ensure proper ventilation in crawl spaces and under‑floor areas.
- Book an annual inspection to catch early signs of new activity.
Frequently Asked Questions
What is the most effective treatment for termites?
The most effective approach combines chemical barriers around the perimeter, baiting systems to eliminate colonies, and regular inspections. This method meets Australian Standard AS 3660 and gives the highest success rate.
Can I treat termites myself?
You can buy products like borax, orange oil, or sprays, but these only work on visible areas. They rarely reach hidden tunnels or eliminate the whole colony, so re‑infestation is common.
How much does termite treatment cost in Sydney?
DIY products cost $100–$300. Professional chemical barriers range from $1,000–$2,500, and baiting systems from $800–$1,500. This is much cheaper than repairs, which average $10,000+.
Is it safe to live in a house during treatment?
Most modern treatments are low‑toxicity and safe for families and pets once dry. Professionals will advise you on ventilation and access times — usually just a few hours.
