The Silent Destroyers and Why Standard Inspections Sometimes Miss Them<\/h3>\n\n\n\n

Termites cause an estimated $1.5 billion in damage to Australian homes every year, according to the CSIRO. The reason the bill is so high is not that termites are undetectable \u2014 it’s that they are often undetected until significant structural damage has already occurred. Subterranean termites travel and feed inside timber framing, beneath flooring, and behind wall linings. A standard visual inspection can detect surface-level signs, but it cannot see inside walls. That’s where thermal imaging changes the equation.

How Thermal Imaging for Termites Works<\/h3>\n\n\n\n

Thermal cameras (also called infrared cameras) detect subtle differences in surface temperature across building materials. Termite activity generates heat \u2014 the metabolic activity of a colony, and the moisture they carry, raises the temperature of the timber they are consuming. This temperature difference (sometimes as little as 0.5\u00b0C) shows up as a distinct pattern on the thermal image, allowing a trained technician to identify suspected termite activity inside walls without making a single hole.<\/p>\n\n\n\n

Modern thermal cameras used for termite inspections typically have a resolution of 320×240 pixels or higher and a thermal sensitivity of less than 0.05\u00b0C. This level of detail allows experienced operators to differentiate between termite activity, moisture ingress, poor insulation, and electrical hotspots \u2014 all of which can present similarly to an untrained eye.<\/p>\n\n\n\n

What Does a Thermal Termite Inspection Involve?<\/h3>\n\n\n\n
    \n
  1. Standard visual inspection first:<\/strong> The inspector begins with a full visual inspection per AS 3660.2 \u2014 the Australian Standard for termite inspections. This covers all accessible areas including subfloor, roof void, exterior perimeter, and internal rooms.<\/li>\n\n\n\n
  2. Thermal scan of walls and ceilings:<\/strong> The inspector moves through the property systematically, scanning all wall and ceiling surfaces. Areas of interest are flagged and photographed.<\/li>\n\n\n\n
  3. Moisture metre confirmation:<\/strong> A moisture metre is used to confirm thermal anomalies \u2014 moisture and termite activity both raise surface temperature. A thermal hotspot confirmed by a moisture spike is a strong indicator of active termite presence.<\/li>\n\n\n\n
  4. Tap testing:<\/strong> In areas of concern, the inspector may use a sounding technique to check for hollow timber \u2014 further confirming the thermal finding.<\/li>\n\n\n\n
  5. Written report:<\/strong> A detailed report with thermal images, moisture readings, photographs, and recommendations is provided.<\/li>\n<\/ol>\n\n\n\n
