Quick Answer
A termite inspection in Melbourne costs $200–$400 for a standard visual inspection or $400–$900 with thermal imaging and moisture detection. Termite treatment costs $1,500–$5,000+ depending on the treatment type and extent of infestation. Annual inspections are strongly recommended in Melbourne’s south-east — Coptotermes acinaciformis is the most destructive termite species in Victoria and causes hundreds of thousands of dollars in damage each year.
Termites cost Australian homeowners more than $1.5 billion per year in damage — more than fire, flood, and storms combined. Most home insurance policies do NOT cover termite damage, which means prevention and early detection are entirely the homeowner’s responsibility. In Melbourne’s south-east, clay soils and established tree cover in suburbs like Berwick, Narre Warren, and Officer create ideal termite conditions.
Termite Inspection Costs
| Inspection Type | Cost (Melbourne) | What’s Included |
|---|---|---|
| Standard visual inspection (AS 3660.2) | $200–$350 | All accessible areas, timber tapping, moisture probe, written report |
| Thermal imaging inspection | $400–$700 | Visual + thermal camera for wall cavities and framing |
| Thermal + moisture + radar | $600–$900 | Most comprehensive — detects hidden colonies |
| Pre-purchase inspection (combined building + pest) | $400–$700 | Combined building defects + termite inspection |
Termite Treatment Costs
| Treatment Type | Cost (Melbourne) | Duration | Best For |
|---|---|---|---|
| Chemical soil barrier (Termidor) | $2,000–$4,500 | 8–10 years | New or post-treatment prevention |
| Reticulation system install | $2,500–$5,000 | Ongoing (replenished every 5 years) | Homes on slab with reticulation pipes |
| Baiting system (Sentricon, Exterra) | $1,500–$3,500 install + $300–$600/year | Ongoing monitoring required | Active infestation; hard-to-trench homes |
| Termiticide dusting (active colony) | $400–$1,500 | One-time treatment | Active colony in accessible location |
| Fumigation (severe infestation) | $2,000–$8,000+ | One-time | Drywood termite severe cases |
| Structural timber repair | $1,000–$50,000+ | Permanent | After active colony eliminated |
Signs You Have Termites
| Sign | Where Found | Action |
|---|---|---|
| Mud tubes (pencil-width tunnels of soil) | Foundation, stumps, fence posts | Do not disturb — call inspector immediately |
| Hollow-sounding timber when tapped | Skirting boards, door frames, floor joists | Get professional inspection within 48 hours |
| Blistered or rippled paint on walls | Wall sheeting, skirting boards | May indicate termites behind wall — get inspected |
| Tight-fitting doors or windows | Internal doorframes | Can indicate moisture or termite damage in framing |
| Discarded wings near windows | Windowsills, near light sources | Indicates swarming — active colony nearby |
| Termite frass (small dark pellets) | Near timber surfaces | Active infestation present — call immediately |
Melbourne Termite Risk by Suburb
Melbourne’s south-eastern suburbs carry elevated termite risk due to clay soils, established tree cover, and older timber-framed housing stock. High-risk areas include:
- Dandenong Ranges, Ferntree Gully, Belgrave — Very high. Native forest areas with established Coptotermes populations.
- Berwick, Narre Warren, Officer, Pakenham — High. Established trees and older housing stock common.
- Frankston, Mornington — High. Coastal clay soils and sandy soils both present.
- Cranbourne, Clyde — Moderate to high. Newer estates less risk, but established areas need annual checks.
Tips & Gotchas
- Annual inspections are non-negotiable in Melbourne’s south-east. Australian Standard AS 3660.2 recommends annual inspections for high-risk areas. Most of SE Melbourne qualifies as high risk.
- Your home insurance does not cover termite damage. Standard home insurance policies explicitly exclude pest damage. The entire cost of structural repair falls on you.
- Chemical barriers degrade in Melbourne clay soils faster than in sandy soils. Check with your pest controller whether your 8-year warranty is realistic for your soil type.
- Baiting systems require annual monitoring. If you install a Sentricon or Exterra system and stop servicing it, you lose protection. Factor in the annual cost of $300–$600.
- Get a pre-purchase pest inspection before buying. Many Melbourne buyers skip this or accept a combined building and pest inspection. A dedicated termite-only inspection by a specialist is more thorough.
- Never store firewood against the house. Firewood against external walls or stumps is a direct termite pathway into your home.
- Fix leaking pipes immediately. Termites are attracted to moisture-damaged timber. A leaking shower or roof gutter that wets the wall framing creates exactly the conditions termites need.
- Verify your pest controller’s licence. In Victoria, pest controllers must be licensed by the Department of Health under the Public Health and Wellbeing Act. Check via Service Victoria’s licence lookup.

FAQ
How often should I get a termite inspection in Melbourne?
Annual inspections are recommended by Australian Standard AS 3660.2 for high-risk areas — which includes most of Melbourne’s south-east. Homes with previous termite activity, those surrounded by trees, or older timber-framed homes should be inspected every 6–12 months. Between formal inspections, check visible timber, stumps, and fence posts yourself monthly.
What is the most effective termite treatment in Melbourne?
Termidor (fipronil) chemical soil barriers are considered the most effective long-term treatment for Melbourne conditions, providing 8–10 years of protection. For active infestations where trenching isn’t possible, baiting systems like Sentricon or Exterra are highly effective but require ongoing annual maintenance. The right choice depends on your home’s construction type and the extent of infestation.
Does home insurance cover termite damage?
No. Standard home and contents insurance in Australia explicitly excludes pest and vermin damage, including termites. The cost of structural repairs after termite damage — which can reach $50,000–$200,000 in severe cases — falls entirely on the homeowner. Annual inspections and preventative treatments are the only financial protection available.
Can I treat termites myself in Victoria?
DIY termite baiting stations are available from Bunnings and can supplement professional treatment as perimeter monitoring, but are not a substitute for professional treatment of an active infestation. In Victoria, applying termiticides (liquid chemical barriers) requires a licensed pest controller under public health regulations. Attempting DIY chemical treatment of an active colony typically disperses rather than eliminates the colony.
