Behavior Patterns

Strictly nocturnal, fast-moving, and thigmotactic (prefers tight cracks and crevices). Highly gregarious and prone to rapid reproduction and infestations.

Risks & Benefits

Major structural/household pest. Poses human health risks by shedding allergens that trigger asthma and mechanically transmitting disease-causing bacteria (such as Salmonella and E. coli) via contaminated surfaces. Offers no significant indoor ecological benefits.
