Learn the key identifying features that distinguish German cockroaches from other common household pests.
Adults are 1/2 to 5/8 inch long with an oval, flattened body shape that allows them to squeeze into tight spaces.
Light brown to tan in color with two distinctive dark parallel stripes running down their back behind the head.
Both males and females have wings, but they rarely fly. Long, thin antennae are as long as their body.

Small, dark specks resembling pepper or coffee grounds
Strong, oily smell in heavily infested areas
Brown, purse-shaped cases about 1/4 inch long
Chewed packages and contaminated food items
Females carry egg cases (oothecae) containing 30-40 eggs for about 30 days before depositing them.
Nymphs molt 6 times over 6-12 weeks, growing larger with each molt.
Adults can live 6-12 months and reproduce rapidly, with females producing up to 8 egg cases.
A single female can produce over 300 offspring in her lifetime, making early intervention critical.
