Ant - Argentine ant
This is a single-node species with small workers only about 2.5 mm long, and with all workers the same size. The Argentine can be separated from the similar ants by its visible node and by its dull gray-black to gray-brown color. When viewed from the side the Argentine Ant has a distinct dip in the top of the thorax. There is no circle of hairs around the anal opening. The first segment of the antenna is not longer than the head, and the legs are not noticeably long, as compared with the crazy ant.
This ant is a small and non-stinging insect, it is a very territorial and aggressive ant that will drive away or kill competing ant species. Neighboring colonies of Argentine ants appear not to be aggressive toward each other. New colonies are often formed by budding off from the parent colony. Nesting is usually in the soil, commonly under concrete slabs, but may also be found in any other convenient void, such as in trees, walls, under insulation, or under debris on the soil. Soil nests are generally very shallow. While protein foods are part of their diet, their preferred foods are sugars, including household food products, fruits in gardens, and honeydew.
Where did they come from?
They were thought to have arrived from Brazil while transporting coffee around 1891,these insects are now found throughout North America, in Hawaii, and on most other continents throughout the world.

How can we help?
Control of most ants includes finding and correcting what drew them to a property, including harborage sites, food sources, and moisture conditions. Elimination of insects that provide protein or honeydew sources reduces ant foraging in an area, very important for this species, and cleanup of unnecessary debris or objects on the soil that provide harborage eliminates nesting. Ant bait products in granular, liquid, or gel formulations can be effective, and carbohydrate baits may be preferred. Locating the nest of these ants is critical, and if it is found treatment directly into the nest with a residual dust insecticide can be effective.
