The argentine ant is very common and difficult to control. With the ability to build nests under just about anything, they can be a real nuisance. Argentine ants are very small ants, around a sixteenth of an inch long. Color can range from light brown to dark brown, they have no stinger - but can bite. These ants sometimes crawl through unsavory conditions such as dead animals or garbage, so they can be carriers of disease. This ant can be found indoors and out. They trail heavily to and from food sources. Inside they eat just about anything that can be found in the kitchen, while outside they eat things like other dead creatures, honeydew from other insects and bee honey. For them to nest inside they like a source of moisture, like under a kitchen sink, or in inside a potted plant. Outside nesting places could be under rocks, garbage cans, concrete, or any place moist and sheltered from light.
