German Cockroaches in the North and East Bay of California

The German cockroach is distributed worldwide and is the most prevalent species in and around homes, apartments, supermarkets, food processing plants, and restaurants. Ships, especially cruise ships and naval vessels, can also be heavily infested. Here in the Bay Area, they are one of the most prevalent household pests for residential and commercial properties. They are fond of the warm humid environment and thus congregate in bathrooms, basements, kitchens, and crawl spaces. When infestations are large, they can spread to other parts of a building. This species reproduces the fastest of the common pest cockroaches—a single female and her offspring can produce over 30,000 offspring in a year.

German Cockroach Habitat

German cockroaches are found primarily in kitchens, bathrooms, or other areas where daily access to water is available. If sanitation is poor, the German cockroach can successfully expand its normal habitat to include all portions of a structure where adequate food, water, and shelter exist. German cockroaches prefer to hide in wooden and paper materials, as well as electrical equipment. These roaches can also be found hiding in cabinets, drawers, up under sinks, and inside heat-producing appliances like dishwashers, microwaves, and coffee makers.

German Cockroach Behavior, Threats or Dangers

German cockroaches are not known to bite humans and will, for the most part, leave you alone. The main concern with German roaches is their rapid rate of reproduction, which makes for some massive infestations. They also can spread disease and germs, as well as allergic reactions due to the insects leaving fecal matter and cast skins around the home, causing skin rashes, watery eyes, sneezing, nasal congestion, and asthma. In addition to spreading disease, German cockroach infestations may cause human psychological stress. Because German roaches are such a common pest for residents in the Bay Area, it’s important to always contact your local cockroach exterminator for assistance with infestations.
