Blattella germanica
- Order & Family
- Blattodea; Blattellidae
- Size
- Nymphs are about 3–12 mm long; adults reach roughly 13–16 mm.
Natural Habitat
Warm, humid indoor areas, especially kitchens, bathrooms, appliances, and wall voids. This specimen appears on a dusty wooden surface.
Diet & Feeding
Omnivorous scavengers feeding on crumbs, grease, starches, pet food, dead insects, and organic debris.
Behavior Patterns
Mostly nocturnal, fast-running, and strongly attracted to warmth, moisture, and food. Females carry an egg case until shortly before hatching, allowing populations to increase rapidly.
Risks & Benefits
They can contaminate food and surfaces and mechanically spread bacteria, while their shed skins and droppings may trigger allergies or asthma. They provide minor ecological value as decomposers, but indoor infestations warrant sanitation and targeted control.
