Thermal Imaging – How it Works to Detect Pests

To protect your home from pests, particularly the extremely damaging termites, helpful building and pest inspections and monitoring are needed. Effective removal of termites means pinpointing the source of the infestation, finding the nest and exterminating the queen responsible for the proliferation of the termites.

There are now technological advances that can be adopted to improve the methods in detecting the presence of termites and to identify the cause of the infestation. One effective method is thermal imaging. Brisbane Building and Pest Inspections makes use of this technology as part of our methodologies in detecting termite infestation.

Non-Invasive Detection

Thermal imaging involves the use of infrared cameras to spot distinctive thermal changes in the property. Infrared imaging does not rely on visible light. Its main function is to visualise the rise and fall of temperature in different areas in the property.

Thermal imaging is favoured because it is non-invasive and non-destructive. This method can map thermal changes within hidden areas, such as within walls and below the soil. This is very important as these areas are the usual hiding places of termites. Being able to see where the termites are without damaging structures is advantageous to the property owner. If there is termite infestation going on within the hidden areas of property, the imaging device will see a distinct change in the thermal image. If the image covers walls, termite infestation appears as dark patches on the infrared image.

Proper Usage

Thermal imaging is very innovative and highly effective, but it must be used correctly. There could be sources of heat that can disrupt the detection process. It is best to remove other possible sources of heat so as to isolate the termite heat signals. For the purpose of the inspection, it is best to turn off machines such as air conditioners, refrigerators and computers, which will register heat changes in the area.

Thermal imaging will also be effective if used in areas with stable ambient temperatures that do not exceed 23 degrees Celsius. During summer, the device should be used during mornings. Other times, it is recommended that the imaging is done during the afternoons when the termites are more active.

At Brisbane Building and Pest Inspections we use thermal imaging as part of our pest detection methods. It is best to use this technology in tandem with other detection methods such as Termatrac, which uses radar technology. When used in tandem, the detection process becomes more accurate.
