Argentine Ants

The population of Argentine ants on Norfolk Island has been significantly reduced over the past five years - but much work still remains. The strategy of the eradication program is to eliminate the smaller infestations first, working our way up to the largest and most complex infestations. Council's Argentine Ant Eradication Team currently use a variety of techniques such as ground baiting, aerial baiting and monitoring using a detector dog. For more information, check out the factsheets below.

What can you do to help?

The cooperation and support from landowners and the community have been fantastic and continue to be crucial if the program is to be successful.

We must all remain vigilant and continue to be mindful of how easily Argentine Ants can be transported around the Island.

Each member of the community must be very careful not to transport Argentine Ants from one area to another. If you live or work within an infested area, please do not move potential carriers of ants from an infested or treated area. Examples include:

  • Pot plants
  • Garden waste
  • Firewood
  • Building waste
  • Earthmovers
  • Chippers
  • Slashers
  • Soil
  • Car wrecks
  • Cow manure, mulch & compost

Community members who are moving materials from within declared Argentine Ant Zones to contact the team beforehand. This allows the team to inspect and treat the material if required, helping to prevent further spread.

The Argentine Ant Eradication Team also offers inspections of ants found on your private property to confirm their identity.

The community is encouraged to report any new infestations by contacting Customer Care.
