Giant Northern Termite Diet

This particular termite is known to have caused more economic loss than any other insect in Northern Australia. The giant termite has the ability to kill a living tree in order to host its colony. In addition to feeding on the cellulose found in wood, they also feed on a range of native trees and plants and will damage ivory and leather. The giant northern termite will also destroy:

  • Lead sheathing around electric cables and water-pipes
  • Concrete and bitumen
  • Paper, jute and cotton
  • Asbestos
  • Silk
  • Wool
  • Grass hay
  • Sugar
  • Bagged salt and flour
  • Citrus
  • Pineapple
  • Vines
  • Banana
  • Paw-paw
  • Melons
  • Pumpkin
  • Carrot
  • Potato
  • Tomato
  • Sugarcane

This makes it extremely difficult to farm vegetables in highly populated areas, such as Northern Australia.

Location and Size Of Colonies

Australia’s giant northern termite typically builds their nests on in the base of tree trunks or tree stumps. In native areas, the giant termite’s population is generally quite small (several-thousands), however when they exist in build-up residential areas their nests have been found to be very large (several-millions).

Detecting a Giant Northern Termite Attack


Early on, the presence of these destructive colonies can be difficult to detect. The most common sign of an infestation is the drying, wilting and yellowing of leaves, as well as the death of entire branches on a healthy tree. Suspected colonies can be affirmed when noticing new growth that wilts and dies fairly quickly, mud-covered galleries on tree trunks (called ringbarking), as well as the folding of tree branches.

Their galleried that stem from the next can be longer than 100m and are typically 20cm underneath the soil’s surface, however, can also be several meters deep when sourcing water or following tree roots.
