Signs of Nasutitermes Attack:
  • mud-packs’ cover the base of the stem

  • the leaves wilt and their colour changes from green to yellow and brown from the top of the tree downwards and from the tips of the branches inwards

  • the upper crown is more or less defoliated
  • due to the ‘pipe’-like excavated base of the tree, a hollow sound is audible when the stem is tapped

  • the cross section of the stem and sawn timber show typical irregular galleries that are often filled with frass and other decaying material

  • occlusion might cover the damaged area of the bark, so that it is no longer visible after a time, even though the termites are still present
