The Argentine Ant is dark brown in color. These ants are very small. They are approximately 3/16th of an inch in length. They have three body sections, and just behind the middle section there is a pointed protrusion that faces upward. The legs of the Argentine Ant are light in color, and its mouth-parts are yellow. This ant has many queens in the colony that will increase the size of the colony and cause the group to disperse in several directions if the colony is disturbed. One of the main reasons that they do this is when they feel threaten either by the nest being invaded by humans, or any kind of smelly insecticides are used. This ant should be either baited with a mild insecticide bait, or a special non-intrusive, non-repellent insecticide that is sprayed in areas that they are found. This kind of product is a restricted material that can only be applied by a licensed pest control operator.
