Red fire ant (Solenopsis invicta)

Tramp ants are a diverse group of invasive ant species which have become established widely across the globe. They can arrive in Australia through many transport pathways, and once here can affect ecosystems, social and cultural values, and human health. At least six tramp ant species have national priority for management because of their impact or potential impact on biodiversity. Management activities to minimise their damage include preventing entry, monitoring high-risk areas, removing new invaders, and dealing with existing incursions.

Key threatening processes

Listed key threatening processes for tramp ants (yellow crazy ants and red imported fire ants) under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EBPC Act) are listed below:

Threat abatement plan

The tramp ant threat abatement plan establishes a national framework to guide and coordinate Australia's response to tramp ants,

Tramp ant species map

The map below shows the distribution of six tramp ant species identified in the Threat Abatement Plan to Reduce the Impacts of Tramp Ants on Biodiversity in Australia and its Territories, 2006. Tramp ants are a diverse group of ant species originating from many regions of the world and are highly mobile. Their impacts are high and may be felt directly through predation upon or competition with native animals, or indirectly by modifying habitat structure and altering ecosystem processes.
