What Is Argentine Ants?

This breed of ants originates from Argentina, Paraguay, Uruguay, Bolivia, and southern Brazil and are classified as one of the most invasive species found globally. These ants are frequently observed in South Africa, New Zealand, Japan, Australia, Europe, and the United States.

Like all other ant species, Argentine ants undergo a developmental process called complete metamorphosis. The duration of this process can vary depending on temperature. However, typically their eggs hatch within 28 days, and the ants reach adulthood within 74 days on average.


Argentine ant workers are typically light to dark brown and have a standard appearance. These tiny creatures measure between 2.2 and 2.8 mm long and frequently move in well-defined trails. When crushed, they emit a musty odour.

In contrast, Argentine queen ants are larger than worker ants and typically measure 4 and 6mm long. In addition, while the worker ants are wingless, reproductive ants may have wings.

Argentine ants tend to inhabit areas beneath wood, logs, and debris, as well as a nest in soil within holes at the base of shrubs and trees. Their nests are shallow and typically at most 20cm.

Female Argentine ants lay white eggs, and after around 28 days, larvae hatch from these eggs and mature into adulthood within 74 days.

Signs of an Argentine Ant Infestation

The presence of broad ant trails is a typical indication of an Argentine ant infestation, which may be observed as they move along trees, buildings, or into homes.

Preventing Argentine Ants

Although taking precautions cannot entirely prevent an Argentine ant infestation, they can significantly reduce the likelihood of their entry into your property.

  • Removing unused building materials and piles of fallen leaves to clear clutter around your property is recommended. Also, avoid storing firewood near your home, which can attract Argentine ants.
  • Frequently trim trees and bushes outside your property, as ants can use them to enter your home.
  • Minimising areas of moisture around your property is also essential. You can do so by not overwatering your plants, ensuring your gutters function correctly, and fixing any leaky pipes immediately.
  • Always store food in sealed containers or the refrigerator and avoid leaving food leftovers on counters or tables.
  • If there are any cracks and crevices in your home’s foundation, it is recommended to seal them immediately.
