Termite Species

copto
Coptotermes

Coptotermes acinaciformis is found throughout mainland Australia and causes more damage to property than any other species. It is aggressive in its search for food and will attack many items other than wood in its search for cellulose materials. It will damage wall lining boards, electrical wiring and even personal possessions. Colonies often nest in trees or stumps but can form nests without ground contact.

 
 
nasit
Nasititermes

There are several species of Nasutitermes which may damage timber in service. Soldier termites of these species are distinguished by their pointed heads. Nasutitermes exitiosus usually builds a low mound and is more common across Southern Australia. Nasutitermes walkeri builds part of its colony as a nest on the branch of a tree; the rest is constructed in the ground beneath it. This genus will mainly attack hardwood such as that found in fences and timber decking.

Mastotermes

Mastotermes darwiniensis, the Giant Northern Termite, is the most primitive of the commercially significant species. It shows an ability for sub-colonies to split from the main colony and produce queens, without a mating flight. Eventually a network of interconnecting sub-colonies is established, which makes control difficult. These large termites can devastate buildings, bridges, poles, trees and crops such as sugarcane. Mastotermes is found mainly north of the Tropic of Capricorn.

 
 
sched
Schedorhinotermes

These termites can cause damage approaching the severity caused by Coptotermes. They build fragile nests in places such as old tree trumps, in timber buried in the ground, in filled patios and under fireplaces. The damage they cause is distinctive. Although it can be severe it is often patchy, with huge gouges taken out of sound timber, particularly around nails in floor boards or other timbers. Schedorhinotermes colonies contain major and minor soldiers.

 
 
heter
Heterotermes

Heterotermes spp. Are a significant structural pest through Queensland, northern WA and the NT. It is only in southern Australia where they are a minor nuisance. They are generally considered to do little damage to timber in service, restricting their attention to weathered timber fences, decking and posts. Occasionally they can cause superficial damage to sound timber.

Termite Nest

Termites build a nest that contains the queen and king, the nursery and a large proportion of the soldiers and workers. Some species build a hard-shelled mound above or partly below the ground. Others build their nests in the trunk of a tree or below ground in the root crown. A nest can contain several million termites.
