Blattella germanica
- Order & Family
- Blattodea, Blattellidae
- Size
- Adults are about 13–16 mm (½–⅝ in) long; nymphs are smaller and wingless.
Natural Habitat
Warm, humid indoor areas—especially kitchens, bathrooms, wall voids, and appliances. The image’s small, light-brown insect and indoor setting are consistent with this species, though the blur limits certainty.
Diet & Feeding
An omnivorous scavenger that feeds on crumbs, grease, starches, pet food, cardboard, and other organic residues.
Behavior Patterns
Mostly nocturnal, fast-running, and concealed in cracks during daylight. Females carry egg cases until hatching; populations can grow rapidly in heated buildings.
Risks & Benefits
Can contaminate food and surfaces and spread allergens associated with asthma and allergies. It has little meaningful household benefit, though it contributes to decomposition outdoors.
