Crematogaster ashmeadi, commonly known as the acrobat ant, is an arboreal ant widespread in the Southeastern United States. It nests and forages almost exclusively above ground level, often found in trees. This ant species has been observed to raid wasp nests and to forage on their brood. They will commonly harborage in wall voids. Workers are one size, between 1/16 inch and 1/6 inch depending on species. Color is variable, but frequently the head and thorax are reddish-brown and the abdomen is black. The abdomen is heart-shaped and is often held upright over the body when the ants are disturbed.

Carpenter ants (Camponotus spp.) are large (0.3 to 1 in or 8 to 25 mm) ants indigenous to many forested parts of the world. Carpenter ant species reside both outdoors and indoors in moist, decaying, or hollow wood, most commonly in forest environments. They cut “galleries” into the wood grain to provide passageways to allow for movement between different sections of the nest. Certain parts of a house, such as around and under windows, roof eaves, decks and porches, are more likely to be infested by carpenter ants because these areas are most vulnerable to moisture.

Tapinoma sessile is a species of small ant that goes by the common names odorous house ant, sugar ant, stink ant, and coconut ant. Their colonies are polydomous (consist of multiple nests) and polygynous (contain multiple reproducing queens). Like many social insects, T. sessile employs complex foraging strategies, allocates food depending on environmental conditions, and engages in competition with other insects. Odorous house ants are small ants about 1/8th inch long and dark brown in color. It is the most common household ant invader.
