Missing Ant Caps in Sub-Floor
Missing Ant Caps in Sub-Floor is a high-severity termite defect SURE inspectors have documented across 286 inspection reports. Highest concentration in Mount Hawthorn.
Causes
- removal
- Lack of installation during construction or removal/deterioration over time
- Incomplete or absent termite protection measures
- Improper installation or removal of ant caps
- Missing or incorrectly installed ant caps
Symptoms to look for
- Ant caps are either missing or not installed on piers/foundation walls
- Visible poor installation, rusting, missing, or defective ant capping
- Absence of visible ant capping/termite shields on stump footings
- No visible ant capping between foundation and timber elements
- No termite shields or ant capping on the stump footings
Remedies
- Regularly inspect the area by a licensed pest inspector.
- Install ant caps or ensure regular inspections by a licensed pest inspector if not practicable to fit
- Regularly inspect by a licensed pest inspector if retrofitting is not possible; consider retrofitting
- Consider installing a chemical treated zone to deter termites from gaining concealed access
- Arrange for a termite treatment in accordance with Australian Standard 3660 to reduce risk

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.
