Common Name: German Cockroach
Order: Dictyoptera Family: Blatellidae Pest Status: German cockroaches are the most common kitchen insect pests in most areas of the world. Appearance: The German cockroach is about 1/2-inch long. It is tan to light brown and has two dark, parallel streaks running from the head to the base of the wings. Although it has wings, it is unable to sustain flight. Life Cycle: Eggs are carried by the female in an external egg case until just before hatching occurs. The nymphal stage begins when the eggs hatch and nymphs must pass through approximately six instars within two months to complete development. Where to Collect: German cockroaches need moisture and can be found in kitchens, bathrooms, and utility rooms. They can also be found hiding in cracks around cabinets, closets, pantries, stoves, refrigerators, and dishwashers. |
