Natural Habitat

Found globally in indoor environments, specifically nesting in wall voids, behind baseboards, and in hidden crevices near moisture and heat.

Diet & Feeding

Omnivorous scavengers that feed on sweets, proteins, oils, and other insects; they often forage for crumbs and grease in kitchens.

Behavior Patterns

Notable for their 'budding' behavior where a new colony is formed by groups of workers and queens leaving the main nest; they are active foragers that create long, distinct trails.

Risks & Benefits

Significant household and hospital pests; they can mechanically transmit pathogens like Salmonella and Streptococcus. They provide no significant ecological benefits in indoor human environments.
