Natural Habitat

Found globally; indoors they nest in warm, humid areas near moisture like wall voids, under floors, and behind baseboards.

Diet & Feeding

Omnivorous; they consume sugars, syrups, fats, and proteins, including dead insects and crumbs.

Behavior Patterns

They form large, multi-queen colonies and are known for 'budding,' where a portion of the colony breaks off to start a new nest if disturbed. They follow distinct scent trails.

Risks & Benefits

Significant indoor pests, especially in hospitals where they can spread pathogens like Streptococcus. They do not sting but are difficult to eradicate due to their budding behavior.
