Different from traditional termite control methods that rely on manual observation, listening, probing, and forcing, which are costly, destructive, and only alleviate symptoms, the use of infrared thermal imaging cameras to non-destructively detect the safety of buildings in termite control is apparently more scientific, intuitive, and efficient.
To prevent continuous damage to the building by termites, it is necessary to first find the feeding cracks where termites enter the building and cut off the path through which termites enter the indoors.
The cracks in the walls where termites enter indoors (through apertures) cannot be directly observed with the naked eye, but can be detected by the infrared thermal imaging camera. Typically, there are slight temperature differences between internal cracks and the surrounding walls, and the infrared thermal imaging camera can manually adjust the temperature range and accurately detect the tiny temperature differences in the wall cracks, thereby easily and quickly detecting the concealed cracks through which termites enter indoors.
Termites require an abundant water source to survive, so once they enter the building, all areas with excessive moisture and water leaks may become their priority habitat.
This time, by using the infrared thermal imaging camera for rapid indoor scanning, multiple walls with low temperatures near water pipelines were found, indicating signs of water seepage or leakage. Therefore, based on the scan results, subsequent rectification is required to restore a dry environment on the walls, so that this area does not become the preferred location for termites to survive.
Termite nests usually maintain a constant temperature and humidity. Due to high humidity, the evaporation of moisture will cause temperature differences between the nest and the surrounding walls. If a nest exists, its temperature will be lower than the temperature of the surrounding walls (and conversely, in areas with lower temperatures or in winter, the temperature in the termite nest will be higher than the surrounding temperature).
The infrared thermal imaging camera detected that the temperature of the wall above the door was lower than the surrounding walls. As a detection tool, the infrared thermal imaging camera provides data support for professional termite control engineers, helping them determine whether there is a nest or other situations present.
Termites can dwell inside the walls of buildings but still need to search for cellulose-based food such as live plants and wooden products. Therefore, it is also important to focus on the detection of wooden structures in the office building, such as wooden doors, cabinets, etc., to see if they have been nibbled on by termites.
When the detection engineer initially discovered termite activity in the outdoor trees, infrared detection was conducted. Since there is no longer a water supply in the hollowed-out areas, the temperature will be higher than the surrounding trees that still have a water supply. This temperature difference is clearly visible in the infrared thermal image. Similarly, the wooden structures inside the room are susceptible to being nibbled on by termites or being chosen as a termite nest location. The use of infrared thermal imaging cameras can detect whether termites are present inside the wooden structures, and can also help detection engineers determine whether this area is a termite nest location, etc.
