Red Carpenter Ants
The red carpenter ant lives in hollow trees and tree limbs. It is smaller and not as common as pennsylvanicus and is more likely to be found in woodland rather that urban areas.
Western Harvester Ants
The western harvester ant is the field ant that builds the large, low, coarse sand mounds in the western half of Kansas. Ants destroy vegetation around the mounds. They feed primarily on seeds they store in the nest and also on small insects. They defend their nests aggressively.
Little Black Ants (Sugar Ants)
The little black ant is one of the most common of small ants on plants and in the home. It is a sweet feeding species.
The acrobat worker is the common, light brownish-yellow ant that can be recognized by its pointed abdomen and pronounced objectionable odor. They feed on sweet juices such as sap, nectar, and honeydew of aphids. When disturbed they elevate their abdomens directing them forward, in an acrobatic manner. They may bite fiercely.
As their name indicates, nests are found outside under cracks of pavement, under stones and next to buildings. Occasionally they may be found in walls, under floors, and in insulation. If your home is a slab on grade construction, pavement ant foragers enter through cracks in slabs or other openings. They often enter buildings through expansion joints in slabs.
