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.
