Thermal imaging is an example of new and innovative technology being used in the pest inspection sector. The technique uses a thermal camera that creates an image based on heat, rather than light. This infrared technology is able to detect temperate and moisture differences in various building materials.
When termites are present, their activity emits heat and indicates a temperate difference. Termites also thrive in a damp environment, so locations with a higher moisture level can also be an indication of an infestation.
Thermal imaging is a non-destructive way to check for termites within concealed walls and spaces. For this reason, it is often used during pre-purchase inspections.
As well as indicating the nest itself, thermal imaging can assist pest inspectors in seeing irregularities in the interior makeup of walls. This is due to the way that heat permeates through a wall, which causes a literal impression of the wall’s interior to be captured by the camera. Serious irregularities can be a sign that termites are present.
During thermal imaging, other sources of heat can be detected, such as pipes, electronic devices and even heat emitted from pets. For this reason, it is important to turn off any appliances and remove pets from the room during the inspection.
