Tapinoma melanocephalum
Tapinoma melanocephalum, the ghost ant, is a small ant with a dark head and pale body, widespread in warm regions and commonly nesting in buildings.
Formicidae: Formicidae is the insect family comprising ants, distinguished by elbowed antennae and a narrow waist. This species belongs to the ant family, whose body plan frames its identification.
Integrated pest management: Integrated pest management combines monitoring, prevention, and targeted control to manage pests while limiting unnecessary pesticide use. Managing ghost ants in buildings works best by locating colonies and reducing access to food and moisture.
Ant colony: An ant colony is a social group organized around reproductive individuals, workers, brood, and shared nest sites. Ghost-ant infestations can comprise multiple nests linked by worker movement.
Pharaoh ant: The pharaoh ant, Monomorium pharaonis, is a small yellowish ant that commonly infests heated buildings. Its indoor habits resemble those of ghost ants, but its uniformly yellow body and different antennae distinguish it.
Biological invasion: Biological invasion is the establishment and spread of organisms beyond their native ranges, often through human activity. The species’ worldwide distribution is a clear example of a small ant spreading through human transport.
Tapinoma: Tapinoma is a genus of small ants in the subfamily Dolichoderinae. The ghost ant is one species within this genus of small, often inconspicuous ants.
Ant bait: Ant bait is a food-based pesticide formulation carried by foraging ants back to their colony. Baits can reach hidden ghost-ant colonies when workers share food with nestmates.
Polygyny: Polygyny is a social system in which one colony contains multiple reproductive females. Multiple queens help ghost-ant colonies persist and expand through budding.
Argentine ant: The Argentine ant, Linepithema humile, is an invasive, brown ant that forms large interconnected colonies. Both can dominate buildings and spread through budding, but Argentine ants are darker and generally larger.
Globalization: Globalization is the intensification of worldwide connections through trade, travel, communication, and migration. Trade and transport provide pathways for ghost ants to reach new warm regions and buildings.
