A group that includes both larger and smaller yellow ant species, citronella ants’ common name comes from the lemon or citronella odor that is emitted when they feel threatened. The distinct smell is most prominent when the ants are crushed. Both species are found throughout a majority of the United States. Often mistaken for termites during swarming activity within homes, citronella ants swarmers are typically light yellow to amber in color. Workers are usually less varied in color and are usually yellow in color. Depending on their species, these ants range in size from 3 to 4.5 mm in length. Spare, erect hairs are found on the head, thorax and abdomen of both species.
