German Cockroach


Brown banded cockroach (Blattella germanica)

A very common small, flat, tan cockroach, Blattella germanica, that grows up to 14 mm long. The adult German cockroaches have two dark stripes. Both the nymphs and adults feed on almost anything, such as starchy, sugary, and proteinaceous foods. They will eat cloth sized with Starch or Glue. The adult insects (10-15 mm in length) can live almost 1 year. The female lay 30-40 eggs in a sausage-shaped case. The eggs hatch into nymphs in 14 days. Cockroaches are nocturnal and are sensitive to light. Common desiccating powders such as Borax, Dri-die, and Sulfur are used along with pesticides to exterminate cockroaches.
