The Little Black ant has similar nesting habits to other ants, though it's biology is not very well understood. It's name comes from the fact this ant is little, and black! (only 1/16" long) Common to this area, the little black ant feeds on many food items it can find in the kitchen. Whether the nest is indoors or out, they can be seen trailing to a food source. If they do build a nest in your house, they prefer decayed woods - but can also build nests in voids or cracks in cement.
