Natural Habitat

Warm, humid indoor areas, especially kitchens, bathrooms, wall voids, and around appliances or plumbing.

Diet & Feeding

Omnivorous scavengers feeding on crumbs, grease, starches, pet food, and organic debris; they may also consume glue, paper, and dead insects.

Behavior Patterns

Mostly nocturnal, fast-running, and highly secretive, hiding in cracks during daylight. Females carry egg cases until hatching, allowing populations to increase rapidly indoors.

Risks & Benefits

Can contaminate food and surfaces with bacteria, allergens, and droppings, and may worsen asthma or allergies. They provide limited ecosystem value indoors but are decomposers outdoors.
