The German cockroach is the most common household and commercial cockroach worldwide. Similar in size to the brown-banded cockroach, they are ½ inches in length. They are ovular-shaped with light brown to tan coloration. Unlike other cockroaches, German cockroaches lack fully-developed wings. They have wings, but can only glide rather than fly with them.
Not as frequently found in homes and apartments, German cockroaches prefer commercial properties with food preparation areas like restaurants, hotels, and nursing homes. Like most cockroaches, they prefer damp, dark areas to live in. Common hiding places for these roaches are enclosed spaces like under appliances or in cracks and crevices.
Female cockroaches can lay up to 50 eggs at a time. Eggs hatch very rapidly within only 24 hours of being laid. However, most young die during the molting time to full maturity. German cockroaches live up to 7-10 months in which a female can produce up to 30,000 offspring in a year.
