Ghost ant workers are extremely small, 1.3 to 1.5 mm long and monomorphic (one-sized). They have 12-segmented antennae with the segments gradually thickening towards the tip. Antennal scapes surpass the occipital border. Head and thorax are a deep dark brown with gaster and legs opaque or milky white. The thorax is spineless.

 

   The ant is easily recognized due to its peculiar color markings and small size. Foragers are seen in kitchens and bathrooms on sinks, counters, and floors. When crushed, the workers emit an odor similar to that of rotten coconuts (Smith 1965).

   The ghost ant is in the same genus as the odorous house ant, Tapinoma sessile (Say). However, the ghost ant is smaller and colored differently since the odorous house ant is entirely dark brown to black.

   The Pharaoh ant is also similar to this species but the ghost ant only has one node on its pedicel compared to two on the pedicel of the Pharaoh ant. Other bi-colored, one-node ants either tend to be much larger or the node on the pedicel is visible from above.

   The best approach to ant control in the home is cleanliness. Any type of food or food particles can attract and provide food for ants. Store all food in tight containers. Remove plants that can attract ants or control aphids, whiteflies and other insects that produce honeydew. Reduce moisture sources, including condensation and leaks.

    If possible, follow the trails of this species back to the nest and treat the nest. If treating the trails with bait check within one or two days to see if the ants are feeding. If not, relocate the bait. Indoor colonies nesting within voids can be controlled with baits. Access of foragers entering from outdoors through cracks and crevices or screens should be restricted with barrier sprays. Generally, control is not necessary except where it becomes a nuisance in the home or in greenhouses
