Argentine ants (Linepithema humile) are small insects that can live both inside and outside your house or building. They can vary in color from light brown, dark brown to black.
Argentine ants go through a life cycle similar to other species. The eggs are white, after 28 days, the larvae emerge from the eggs, at approximately 74 days, they reach their adult stage.
They can be found outside the home in damp places such as under rocks, mulch, concrete slabs, tree or wood debris, fallen logs, etc. Indoors can be found in wall voids, around moisture, and damaged wood. They will move if they notice that their habitat is being affected or find a good food source.
If you have an Argentine ant infestation, you should know that it is difficult to control because its biology is unusual. They differ from other ants species because Argentine ants have many queens, and worker ants can return to their desired nest.
They can form a super colony that is often linked by tunnels. Outside they can find many nests that will be difficult to locate, so you must use treatments such as baits to eliminate them correctly. Queen ants are different from the other queens of the other species, and each can lay up to 60 eggs a day.
Argentine queen ants are smaller; they can be between 1/6 to ¼ inches long. The Argentine ants’ queens can be seen outside their nest with the workers. The other queens are in the nest for life. Males are short-lived, and their only function is to mate with a queen.
How to Identify Argentine Ants?
Argentine ants are small, light brown, dark brown to black. They can be 2.2 to 2.8 mm long.
