Dead trees and brush are the original food source of subterranean termites. When land is cleared of this material and houses are built on these sites, termites attack the structures. Termites can enter buildings through wood in direct contact with the soil, by building shelter tubes over or through foundations, or by entering directly through cracks or joints in and under foundations.
Any material in direct contact with the soil (such as trees, vines or plumbing fixtures) serves as an avenue of infestation. Subterranean termite swarmers may also be blown into or on structures and then start a new colony.
Subterranean termite damage almost always is confined to the soft, springwood growth of the wood. Tunnels tend to follow the wood grain. They either are lined with the same material used to build shelter tubes, or have a pale, spotted appearance resulting from soft fecal material plastered on tunnel surfaces. Look for moisture sources that may cause wood decay, which can encourage subterranean termite infestation.
Extensive deterioration from wood decay can be confused with termite damage. The Termatrac Termite Detection Radar has revolutionized termite detection in enabling the operator to easily identify and confirm the presence of termites if wood decay, or other signs of termites have been found.
The Termite Detection Radar within the Termatrac T3i sends a specially calibrated radar signal through the building structure, avoiding the need to physically penetrate and create damage to the building. The Termatrac Termite Detection Radar can precisely locate nests, mud-leads, and entry points to ensure a cost-efficient and effective treatment can be applied to only the areas required.
If the termite damage is not apparent to the naked eye, the Termatrac T3i has the required tools built in to identify termite risk areas. The Remote Thermal Sensor with Laser Guide operates in a similar manner to a Thermal Imaging Camera, locating termite risk areas via changes in the building surface temperatures. In addition, the T3i also has a built in Moisture Sensor to identify concentration of moisture in building structures which typically comprise termite risk areas.
