No Visible Evidence of Previous Termite Treatment
No Visible Evidence of Previous Termite Treatment is a high-severity termite defect SURE inspectors have documented across 611 inspection reports. Highest concentration in Ellenbrook.
Causes
- Potentially ineffective or poorly documented previous treatment.
- Unconfirmed efficiency of existing termite protection system
- Unconfirmed efficacy of existing termite protection system
- Absence of visible previous termite treatment evidence
- No treatment applied, or evidence concealed/degraded
Symptoms to look for
- Absence of drill holes, treatment notices, or other signs of previous treatment
- No visible documentation or clear evidence of past termite treatments
- No visible evidence of a previous termite treatment was located
- Uncertainty about ongoing termite protection efficacy
- Illegible or worn durable notice in the meter box
Remedies
- Engage a pest control technician to review the termite site management plan and install a new chemical barrier
- Obtain copies of all paperwork and make inquiries regarding previous termite work and warranty information
- Arrange for a treatment in accordance with Australian Standard 3660 to reduce the risk of further attack
- Contact the treatment company (if identifiable) to obtain information about past treatments and warranty
- Engage a pest control technician to implement a termite site management plan in accordance with AS3660

Curated entries in Termite
- Curated 2–4/5Slab Edge Concealed by Soil, Paving, or Raised Garden Beds
I walked the perimeter and could not see a continuous strip of exposed slab edge - raised garden beds, soil, paving, or decorative stone have buried it. Reference: AS 3660.1 and AS 3660.2. In my experience a concealed slab edge lets subterranean termites bridge the edge barrier out of sight, entering the cavity or framing without leaving mud leads where I can find them.
- Curated 1–4/5Mulch and Garden Beds Against House
Organic mulch and irrigated garden beds placed directly against the external walls create a moisture-rich, cellulose-rich environment that is attractive to subterranean termites and conceals the slab edge from visual inspection. AS 3660.1 and AS 3660.2 identify direct contact between landscaping materials and the structure as a conducive condition requiring correction.
- Curated 1–5/5Timber in Contact with Ground
Timber structural elements - deck posts, pergola framing, sleeper retaining walls, or firewood stacks - sitting directly in or against soil create an unobstructed termite pathway into the building and accelerate fungal decay. AS 3660.1 requires all structural timber to be isolated from soil to maintain a visible inspection zone; ground contact eliminates this requirement entirely and removes any chance of early detection.
- Curated 1–4/5High Termite Risk Due to Environmental Surrounds
The property's location near large trees, bushland, or parkland places it in elevated termite territory. Proximity to established timber sources and native vegetation significantly increases foraging pressure on nearby structures, and AS 3660.1 recognises environmental context as a primary risk factor when specifying termite management requirements.
- Curated 1–4/5Concealed Internal Wall Areas (Termite Risk)
Internal wall cavities, top plates in the roof space, and sub-floor framing cannot be visually inspected during a standard building inspection. AS 4349.3 requires inspectors to report whenever access limitations prevent verification of timber condition - these concealed zones are where termite activity most commonly goes undetected until structural damage is advanced.
- Curated 1–4/5Tree Stumps on Site
Tree stumps left in the ground provide an established food source and potential nesting site for subterranean termites. Once a colony is established in a stump, foraging extends radially - typically 50–100 m - placing any timber-framed structure on the property within reach.
