Omnivorous; they feed on a wide variety of foods including sweets, proteins, and fats (syrup, jelly, grease, and dead insects).
Behavior Patterns
They are known for 'budding,' where a portion of the colony moves to a new location if disturbed. They follow distinct chemical trails to food sources and are active year-round indoors.
