Electric ant

The exotic pest commonly known as the electric ant or little fire ant (Wasmannia auropunctata Roger) was detected in Queensland in May 2006 at Smithfield in Cairns. It has since been found in several other areas in Far North Queensland.

Biosecurity Queensland is undertaking an electric ant eradication program — for the latest information, visit the Department of Agriculture and Fisheries website.

Electric ant has not been detected in Victoria.

Alternatively, you can make a report via our online form with a photo (where possible).

What electric ants look like

Adult electric ants are only about 1.5mm long

  • Unlike red imported fire ants, electric ant workers are all the same size.
  • The ants don't have a distinctive nest or mound and tend to nest under leaf debris and stones, in rotten limbs or in trees. They have been known to nest in houses, infested beds, furniture and food.
  • Electric ants produce painful, long-lasting stings, often resulting in red, itchy pimples. Sometimes it might cause a severe allergic reaction.
  • The ant have been known to attack pets, as they are attracted to pet food.

Importing host materials into Victoria

To prevent the importation of electric ants into Victoria, we introduced restrictions on the movement into Victoria of any material capable of harbouring electric ants.

Where electric ants are found

The electric ant is native to Central and South America, but has established in:

  • the West Indies
  • Mexico
  • West Africa
  • Galapagos Islands
  • New Caledonia
  • the Solomon Islands

Its impact is similar to red imported fire ants, in that it injects a powerful venom when it stings.

How electric ants can spread

Electric ants spread mostly through human activity with the movement of plants, plant products or edible material. Once the ant has established it is known to spread up to 170m per year, with a more typical rate range of 0 to 25 metres per year depending on the environment.
