What is a German cockroach? 

German cockroaches live in close association with people all across the world. Over time, these small, adaptable roaches have learned the benefits of living with people and almost exclusively live inside homes, restaurants, grocery stores, warehouses, and other places where food is prepared or stored. They cannot thrive in cold temperatures, which is why they do so well inside temperature-controlled structures. 
 
German cockroaches have a tannish-brown body with two dark parallel lines between their head and thorax. They have wings but prefer to run from place to place instead of flying. The German cockroach’s dark coloring allows these pests to hide largely out-of-site during the day while resting. Nocturnal, German cockroaches emerge from their hiding spots at night to forage for food.

Are German cockroaches dangerous?

There are many reasons why German roaches are dangerous pests and should never live inside a home or business for long.

  • As German cockroaches crawl through drawers, over counters, and inside cabinets and pantries, they contaminate food and surfaces with bacteria, pathogens, parasites, excrement, and saliva.

  • They chew on and damage clothing, furniture, rugs, and other personal items.

  • They produce unpleasant foul-smelling secretions that take over a home and affect the flavor of food.

  • Having German cockroaches living in your house is a risk factor for developing allergies and producing asthma attacks in young children.

  • German cockroaches breed and establish large populations very quickly. Having large amounts of cockroaches living in a home causes a lot of financial and mental strain.

Why do I have a German cockroach problem?

German cockroaches can become a problem inside any structure that prepares or stores food. One of the biggest attractants for German cockroaches is the smell of food, especially rotting food in garbage bins. 
 
German cockroaches can find their way into your home on their own, crawling through spaces in walls, floors, and under doors. They also find their way inside by hitchhiking inside cardboard boxes, deliveries, grocery bags, and like items.

Where will I find German cockroaches?

German cockroaches are adaptable and can live in almost any environment, except, of course, one that is very cold; they prefer to live in areas with a lot of heat and humidity. They do best and are most active when temperatures are between 85 and 95 degrees and humidity levels are between 90 and 95 percent. 
 
Inside our homes, German cockroaches tend to gather in kitchens, behind appliances, in damp basements, inside laundry rooms, and behind wall voids near leaking pipes or heating or air conditioners. 
 
Except in the case of a large infestation, you likely won’t see German cockroaches during the day. People often discover an infestation after turning a light on in the bathroom, basement, or kitchen in the middle of the night and see them scurrying away.
