German cockroach

Warm, humid indoor sites—especially kitchens, bathrooms, wall voids, and areas near food, water, or appliances.

Omnivorous scavengers that eat food scraps, grease, starches, sweets, paper, glue, and other organic material.

Mostly nocturnal, fast-running, and shelter-seeking; they hide in cracks by day and reproduce rapidly, with females carrying egg cases until hatching. The image is consistent with a German cockroach, though blur limits certainty.

They can spread contaminants and shed allergens associated with asthma and dermatitis. They provide little household benefit, though cockroaches generally recycle organic matter in natural ecosystems.
