What are Argentine ants?

Argentine ants are minuscule black ants native to South America that made their way to the United States in the late 1800's. They are mostly found in the southern and southwestern states. Adult Argentine ants grow from 1/16 to 1/4 inch in length, and range in color from light brown to black. Their bodies are otherwise typical for ants, with six legs, an oval-shaped body, and two 12-segmented antennae.

Are Argentine ants dangerous?

As they are not known to bite or sting, Argentine ants are generally not considered dangerous household pests. However, like other invasive ant species, this does not stop them from indirectly harming humans in the form of the food they access and contaminate when they invade homes.

Why do I have an Argentine ant problem?

Argentine ants are known for their extremely large colony sizes. A single colony could have over a million workers bred and overseen by hundreds of queens. These massive colonies are part of the reason why they’ve been able to spread so effectively throughout the U.S. Like other ant species, Argentine ants are attracted to moist environments with access to food.

Outside, Argentine ants are commonly found around the edges of sidewalks and near landscaping. Argentine ant infestations generally occur either when the weather becomes too wet or too dry. Wet weather provides viable sources of food and water outdoors whereas dry weather forces these ants into homes where they can find access to moisture.

Argentine ants typically enter homes through cracks in the foundation or gaps found around exterior windows and doors as they forage for food. Like many ants, Argentine ants prefer to eat sweet foods but will also forage for meats, eggs, oils, and fats found throughout your home. Leaving these types of foods out in the open is a sure way to attract the attention of any Argentine ants that have found their way into your home.
