German cockroach

Warm, humid indoor areas—especially kitchens, bathrooms, cabinets, and appliance spaces—where food and water are available.

Omnivorous scavengers feeding on crumbs, grease, starches, sweets, pet food, cardboard, and other organic residues.

Primarily nocturnal, fast-running, and shelter-seeking; they hide in cracks during daylight and reproduce rapidly, with females carrying egg cases until hatching.

They can contaminate food and surfaces and carry allergens associated with asthma and dermatitis. They provide little household benefit, though cockroaches generally recycle organic matter outdoors.
