Natural Habitat

Indoor environments like kitchens, hospitals, and heated buildings; they nest in warm, humid voids like wall cavities or behind baseboards.

Diet & Feeding

Omnivorous; they scavenge for sweets, proteins, and fats, including jelly, sugar, honey, and even dead insects or greasy materials.

Behavior Patterns

Highly social and persistent pests; they utilize 'budding' where a queen and workers move to form a new colony if the original group is disturbed by chemicals.

Risks & Benefits

Significant risk as a mechanical vector for pathogens like Staphylococcus and Salmonella, especially in clinical settings; they offer no ecosystem benefits in an indoor human environment.
