Tapinoma sessile is a species of small ants that goes by the common names odorous house ant, sugar ant, stink ant, and coconut. The colony consists of multiple nests with many queens for reproduction purposes. These creatures have different strategies in their food-gathering habits depending on environmental conditions.
The odorous house ant has become one of the most difficult ants to control in Kentucky and much of the Midwest. The ant is small (1/8-inch), blackish, and forms distinct trails along surfaces.
