Natural Habitat

Warm, humid indoor areas—especially kitchens, bathrooms, wall voids, and around appliances. It hides in cracks during daylight and emerges at night.

Diet & Feeding

Omnivorous scavengers that consume food scraps, grease, starches, cardboard, soap residue, and other organic matter.

Behavior Patterns

Fast-running, nocturnal, and highly reproductive; females carry an egg case until shortly before hatching. Nymphs lack wings and develop through several molts.

Risks & Benefits

Can contaminate food and surfaces and spread allergens associated with asthma and dermatitis. They provide little household benefit, though they serve as prey for predators outdoors.
