Fire ant bites cause a severe burning sensation in humans, & a small number of deaths have occurred. They also pose a risk to crops, animals, farm equipment & native flora & fauna.


Yes, you do want fire ants eradicated.

Natives of South America, fire ants first appeared in Australia in Brisbane, Queensland in 2001. At least in part, due to an inadequate response by successive governments, that infestation continues to this day. In their defence, where a fire ant infestation has been established, fire ants have not been eradicated from any country in the world. To date, in Australia, federal, state & local governments have spent $281 million trying to eradicate them. In 2009, a government report estimated the cost of the infestation to Queensland, at $43 billion over 30 years.



Genetic testing indicates that the Sydney infestation is not related to that in Queensland.

Identification:

Fire ants are small, ranging in size from 2-6 mm, with a variety of sizes within each nest. Head & body are coppery-brown & the abdomen darker.

Fire ant mounds may be found in open fields, & can be up to 40cm high, but may also be flat, like a patch of disturbed soil. Nests may also found under timber, logs, rocks, pavers, bricks or other objects on the ground. Infestations of buildings can occur.
