German Cockroaches in Southern California

The German cockroach is distributed worldwide and is by far the type of roach that reproduces most quickly. Here in the Los Angeles Metro Area, it is known to inhabit homes, apartments, supermarkets, food processing plants, and restaurants. It also commonly infests cruise ships and naval vessels. Because these roaches prefer warm environments, it is common to see them inside of buildings, especially in both residential and commercial kitchens. 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 Threats

German cockroaches are not likely to bite humans even though they have the ability to do so. The main concern with these pests are the fact that they can spread bacteria and germs so easily. German cockroaches can also cause 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. Their infestations can grow to massive numbers, making it difficult to know how to get rid of them when you notice them. This makes it important to always contact your local cockroach exterminators for help.
