Subterranean Termites, also known as “white ant”, feed exclusively on cellulose-based materials such as wood and paper. They are able to tear off extremely small fragments of wood using their hard, saw-toothed jaws. Subterranean Termite nest in the soil and often infest buildings and damage lumber wood panels, flooring, wallpaper, paper products and fabric made of plant fibers. The most serious damage results from the loss of structural strength.

Subterranean Termites rarely come to the surface to feed, so most of the time, you will only find out that they are there when it is too late. Some signs that one can look out for as a warning of their presence.

  • Presence of mud shelter tubes over the surface of walls and wood structures.
  • Acoustic signal termites gnawing on and knocking against wood surface (clicking sound).
  • Damage on wood structure.

The most common species that we encountered at building structure is Coptotermes sp., while the common species found on trees are Microcerotermes sp., Globitermes sp., and Nasutitermes sp.

Management Strategies

Detection

To identify temperature anomalies within the operating range in the structure. When anomalies are detected, further investigation and analysis will be conducted using T3i to determine if the infestation is active.

Thermal Image

Visible Light Image

To detect temperature and moisture changes on large surface areas. Significant differences in temperature/moisture on certain spots in a building/structure is a typical sign of termite risk area. T3i also detects the movement of termites as it is equipped with termite detection radar.

Treatment

  • To attract foraging termites to the feeding stations that contain a suitable bait matrix which is then carried back and shared among their nestmates. The slow acting toxicants gradually reduce the termite numbers and ultimately eradicate the entire colony.
  • Regular follow-up inspections and monitoring provide on-going protection to the structure.
To stick dust toxicants onto the termite body by introducing them into the termite galleries. The affected termites then transfer the dust toxicants to others through direct application, mouth to mouth feeding, grooming, or contact and eventually kill the entire colony.

Preventive Measures

  • Concept: To create a continuous chemical barrier between building and soil before it is built.
  • Benefits:
    • To protect the entire building from a termite entry and to eliminate termite colony if it is present.
    • Effective and cost-efficient way to prevent termite infestation.
    • Last for at least five years.
  • Concept: To establish a chemical treated zone around the exterior foundations after the building is in place.
  • Benefits:
    • To protect against future termite attack and to eradicate the entire termite colony if it is present.
    • Effective and cost-efficient way to prevent termite infestation.
    • Last for at least five years.
