Cockroach nymph (likely German cockroach)
Blattella germanica
- Order & Family
- Blattodea, Blattellidae
- Size
- Nymphs are about 2–12 mm; adults reach 13–16 mm (½–⅝ inch).
Natural Habitat
Warm, humid indoor areas—especially kitchens, bathrooms, cabinets, and laundry spaces. They hide in cracks and near food, water, and appliances.
Diet & Feeding
Omnivorous scavengers eating crumbs, grease, starches, sweets, pet food, and organic debris.
Behavior Patterns
Mostly nocturnal, fast-moving, and strongly shelter-seeking; they hide during daylight. Females carry an egg case until hatching, and populations can grow rapidly indoors.
Risks & Benefits
They can contaminate food and surfaces and spread allergens associated with asthma and dermatitis. They provide little household benefit, though cockroaches recycle organic matter outdoors.
