Blattella germanica
The most common indoor cockroach worldwide — small, light brown, and the fastest-breeding species, requiring professional control.
Know the German Roach
Size
1.2–1.5 cm (≈ 0.5 in)
Appearance
Light brown to tan with two dark parallel stripes on the thorax. Small, oval, flat body with long threadlike antennae.
Feeding
Opportunistic — sugary spills, grease, leftover food, and even glue or toothpaste. Survives on minimal resources.
Behavior
Hides in tight cracks behind appliances and inside cabinets. Reproduces faster than any other roach species — a single egg case can hold 30+ eggs.
Habitat
Warm humid spaces near food and water — kitchens, bathrooms, behind refrigerators, dishwashers, and inside cabinetry.
Signs of Infestation
- Small light-brown roaches in kitchens at night
- Droppings resembling fine coffee grounds
- Egg cases (oothecae) glued in tight spaces
- Strong musty smell in cabinets
Health & Property Risks
Spread Salmonella, E. coli, and trigger asthma and allergies. The fastest breeders among indoor roaches.
