Although adults have fully developed wings, they do not fly.
Unlike Asian Cockroach, females do not have wings long enough to cover the oothecae.
Infests human dwellings and workplaces
Omnivorous, eats just about anything edible
Like most cockroaches, the German Cockroach is nocturnal. It is a major pest of residential and commercial structures.
Some people can develop severe allergies to cockroach parts, feces, and oils.
Females carry the ootheca for up to a month, dropping it just before the eggs hatch.
