Natural Habitat

Worldwide distribution, primarily living indoors in close proximity to humans. They prefer warm, humid areas with easy access to food and water, such as kitchens, bathrooms, and laundry rooms.

Diet & Feeding

Omnivorous scavengers that eat almost anything, including human food, pet food, grease, soap, glue, and even book bindings.

Behavior Patterns

Mainly nocturnal and very fast runners. They have a high reproductive rate and a hemimetabolous life cycle (egg, nymph, adult). They are known for hiding in narrow cracks and crevices during the day.

Risks & Benefits

Significant household pest and public health risk. They can spread pathogens, contaminate food, and their droppings or shed skins can trigger asthma and allergic reactions in humans.
