How to Identify German Cockroaches

Learn the key identifying features that distinguish German cockroaches from other common household pests.

Physical Characteristics

Size & Shape

Adults are 1/2 to 5/8 inch long with an oval, flattened body shape that allows them to squeeze into tight spaces.

Color & Markings

Light brown to tan in color with two distinctive dark parallel stripes running down their back behind the head.

Wings & Antennae

Both males and females have wings, but they rarely fly. Long, thin antennae are as long as their body.

Juveniles (Nymphs)

Smaller, darker, and wingless. They look similar to adults but are about 1/8 inch when newly hatched.

Behavior Patterns

Nocturnal: Most active at night
Fast moving: Quick to hide when lights turn on
Heat-seeking: Prefer warm, humid areas
Social: Live in groups and communicate through pheromones

Signs of Infestation

Droppings

Small, dark specks resembling pepper or coffee grounds

Musty Odor

Strong, oily smell in heavily infested areas

Egg Cases

Brown, purse-shaped cases about 1/4 inch long

Food Damage

Chewed packages and contaminated food items

Life Cycle

1

Egg Stage

Females carry egg cases (oothecae) containing 30-40 eggs for about 30 days before depositing them.

2

Nymph Stage

Nymphs molt 6 times over 6-12 weeks, growing larger with each molt.

3

Adult Stage

Adults can live 6-12 months and reproduce rapidly, with females producing up to 8 egg cases.

Rapid Reproduction

A single female can produce over 300 offspring in her lifetime, making early intervention critical.
