Tapinoma melanocephalum, commonly known as the Ghost Ant, is a small yet widely distributed species that has earned its reputation as a persistent household pest in tropical and subtropical regions. Believed to have originated from the African or Oriental regions, this species has spread to many parts of the world, including the United States, where it is particularly prevalent in Hawaii, Florida, and even as far north as Texas. Despite its invasive tendencies, the Ghost Ant remains a favorite among ant keepers for its fascinating biology and rapid colony growth.

In its natural environment, Tapinoma melanocephalum thrives in tropical climates and is commonly found within greenhouses and buildings, where the conditions mimic its native habitat. These ants are extremely small, with worker sizes ranging from 1.3 to 2.0 mm and queens measuring slightly larger at 3–4 mm. Their bodies feature a dark brown head and thorax contrasted with milky white legs and abdomen, making them nearly invisible to the untrained eye. The species is monomorphic, with workers all exhibiting similar features, and they are known for their impressive agility and rapid movements. Ghost ants are active foragers that feed on a variety of substances including honey water, insects, and even fruits. Their ability to quickly exploit food resources, combined with their tendency to form large colonies of up to 3,000 individuals, makes them both ecologically significant and a challenge to manage in natural settings.
