What Are Argentine Ants?

Argentine ants range from light/dark brown to black and shiny and measure 1/16 to 1/4 inch long. The ant gives off a musty odor when crushed.

Argentine ants adapt easily and can nest in a variety of places. Colonies are massive and may contain hundreds of queens. Nests are usually located in moist soil, next to or under buildings, along sidewalks or beneath boards. The foraging trails of Argentine ants are their most visible sign. They travel with well-defined trails between their web of nests and their food sources. The trails can be observed traveling up buildings, trees and into homes.
