Termite Treatment Cost Australia 2026: Barriers, Baiting & Inspections

Termite Treatment Cost in Australia 2026: Quick Summary

Termite treatment in Australia costs $2,900–$3,600 for a full chemical barrier on an average property in 2026. Baiting systems cost $1,500–$3,800 to install plus $250–$360 per year for monitoring. Physical barriers run $2,000–$4,000 and last decades. Inspections cost $220–$330 for standard visual, $350–$600 with thermal imaging.

Around 180,000 Australian homes are affected by termites every year, generating more than $4 billion in damage annually. Standard home insurance does not cover termite damage. This guide covers every treatment method with 2026 pricing, a Termidor vs Sentricon comparison, and cost by property size. See our national pest control costs guide.

Chemical Barrier Treatments: Termidor and Biflex

Chemical barriers are the most common treatment for existing homes. A licensed technician applies termiticide to soil around and beneath the structure.

Termidor (Fipronil)

Market-leading at $30–$40 per linear metre, full treatments averaging $2,900–$3,600. Non-repellent — termites carry the active to the colony, eliminating it.

• Lasts 8–10 years
• $2 million product warranty when applied by accredited technician
• Non-repellent — colony elimination, not just exclusion
• APVMA registered

Biflex (Bifenthrin)

Main alternative at $20–$35 per linear metre, treatments $2,500–$3,500. Repellent product — forms barrier termites detect and avoid.

• Lasts 5–8 years
• Lower cost suits lower-risk properties
• May drive activity sideways if installation isn't continuous

For high-risk QLD, NT, and NSW properties, Termidor's premium is justified. For lower-risk VIC and TAS, Biflex offers value. See termite identification guide.

Baiting Systems: Sentricon and Exterra

Baiting systems intercept foraging termites with stations around the building. Termites feed on bait and carry it to the colony.

Sentricon

Installed with 12 months monitoring: ~$3,800. Annual monitoring $250–$360/yr after first year.

Exterra

Installation $3,000–$3,200. Annual fees comparable at $250–$360/yr.

10-Year Cost Comparison

Termidor barrier at $3,200 lasts 8–10 years — no ongoing fees. Sentricon over 10 years: ~$6,800 total. Baiting costs 2–3× more long-term but suits difficult-access properties.

Physical Barriers

Installed during construction: $2,000–$4,000. Types include Granitgard (crushed granite), Kordon (plastic sheeting), and Termi-Mesh (stainless steel). Cannot be retrofitted. Pre-construction soil treatment alone: $200–$2,500.

Termidor vs Sentricon: Direct Comparison

Factor	Termidor	Sentricon	Exterra	Physical
Initial cost	$2,900–$3,600	~$3,800	$3,000–$3,200	$2,000–$4,000
Annual ongoing	None	$250–$360/yr	$250–$360/yr	None
Warranty	$2M product	Via renewal	Via warranty	Lifetime
Duration	8–10 years	Ongoing	Ongoing	Decades
Colony elimination	Yes	Yes	Yes	No (exclusion)
10-year cost	~$3,200–$3,600	~$6,050–$7,000	~$5,250–$5,800	$2,000–$4,000

Cost by Property Size

Property Size	Perimeter	Termidor	Biflex	Baiting
Small home/unit	~60–80m	$1,800–$3,200	$1,500–$2,800	$1,500–$5,250
3-BR single storey	~80–100m	$2,400–$4,000	$2,000–$3,500	$2,000–$6,500
4-BR double storey	~100–130m	$3,000–$5,200	$2,500–$4,550	$3,000–$9,500+

Inspection Costs

Every treatment begins with inspection. See our termite inspection costs guide and pre-purchase inspection costs guide.

• Standard visual: $220–$330 — AS 3660.2 compliant
• Thermal imaging: $350–$600 — detects concealed activity
• Pre-purchase (AS 4349.3): $400–$600

Why Treatment Cost Beats Repair Cost

Termite damage costs $4 billion per year nationally, affecting 180,000 homes. Insurance covers $0.

• Floor joists: $5,000–$25,000+
• Wall framing: $2,000–$15,000+
• Roof trusses: $4,000–$30,000+
• Average repair: $5,000–$10,000
