Natural Habitat

Typically found indoors in climate-controlled buildings, often nesting in wall voids, behind baseboards, and near moisture sources.

Diet & Feeding

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.

Risks & Benefits

Significant indoor pest risk; they can spread pathogens such as Salmonella and Streptococcus, particularly in hospital settings. They provide little benefit to humans in indoor environments.
