    • is typically larger and more pointed than that produced by the native drywood termite, C. primus
    • is distinguishable from ant debris, which contains fibres or parts of dead insects.

Drywood termites cause damage to timber structures in coastal areas and adjacent tablelands in Queensland.

Each of the 4 introduced species has a restricted distribution within this zone, but the native species, Cryptotermes primus, is more widespread. Other native species are of little economic importance.

West Indian drywood termite attack is restricted to:

  • construction timber
  • furniture
  • rarely paper.

Monitoring and action

Knowing the habits of drywood termites as well as having regular house inspections are the best protection against these pests.

You may accidentally discover infestations by breaking into a gallery in floorboards or windowsills.

Currently, fumigation treatment bears no cost to the householder. You must accurately identify the species before treating.

If you find evidence of West Indian drywood termite activity, collect a sample of the frass or termite wings and, if possible, several soldiers. Contact our Customer Service Centre for advice.
