Description of Workers: Brown to blackish small ants, about 1/8-inch (3 mm). Key identifying characteristic is that the pedicel attaches to the upper part of the abdomen. When viewed from above, the abdomen is heart-shaped.


Acrobat ants often tunnel and nest in wood. They live in decaying tree stumps and can live in woodwork especially door or window frames. Acrobat ants may nest in wood already damaged by carpenter ants or termites. Nests are also found in foam insulation. Nest locations are often associated with moisture problems and water leaks. Acrobat ants feed on honeydew produced by aphids.


Management includes locating and appropriately treating colonies. Baits are not effective
