Detecting and identifying West Indian drywood termite

West Indian drywood termite (WIDT) is difficult to detect as it can establish colonies in concealed areas of houses and buildings.

WIDT does not need contact with soil moisture and can establish independent colonies within a structure. These colonies can be very small and hard to detect because the openings to galleries become sealed with faecal pellets known as frass.

It can take around 5 years (or even longer) for WIDT to be detectable. The signs of infestation include:

  • frass appearing in the corners of rooms
  • termites and/or wings appearing in rooms after storms in late spring or early summer.

Timber close to the frass pile will have a small ejection hole (1mm diameter), but this may be sealed and difficult to see.

WIDT is commonly found in pine (especially hoop pine) and in cabinet woods such as maples (Flindersia species), red cedar (Toona australis) and silky oak (Grevillea robusta).

Damage is generally restricted to construction timber, wooden furniture and relocated houses. WIDT is not known to occur in the wild in countries where it has been introduced (outside its natural range in Central and South America).

WIDT was first detected in Maryborough in 1966. It is now established in many suburbs in Greater Brisbane and in other Queensland coastal towns and settlements.
