See this bug in the Encyclopedia

Natural Habitat

Disturbed areas, greenhouses, and residential environments; often nests indoors in wall voids or flowerpots in tropical and subtropical climates.

Diet & Feeding

Honeydew-producing insects (like aphids) and sweet liquids; in homes, they forage for sugary foods and grease.

Behavior Patterns

They move rapidly and erratically when disturbed. They are highly adaptable and form multiple interconnected colonies (polygynous), allowing them to spread quickly.

Risks & Benefits

They do not sting and their bite is usually unnoticed, but they are significant nuisance pests in homes and hospitals as they can contaminate food and surfaces. They provide minimal ecological benefit in urban indoor environments.
