What is the Life Cycle of a German Cockroach?

Cockroaches have been around since the dawn of time and, according to legend, will be around long after you and I are gone. They are said to be able to survive a nuclear detonation. The most common is the German cockroach. Would you believe that this species of roach even has wings, yet do not fly? They do wreak havoc around kitchens and bathrooms, though. 

The Life Cycle of a German Cockroach

You might not think that the roach we have the most problems with, within the United States, would have a foreign name, but it does. The German cockroach is a small brown insect, 1/2” to 5/8” long, is oval in shape, has six legs, and has long antennae. There are three stages in their life cycle:

Egg

The roach egg is carried in a casing called an ootheca. It houses 30-40 eggs. This purse-like pouch is carried by the female until the eggs are ready to hatch. She will carry the ootheca around for about a month.

Nymph

The nymph stage begins as soon as the eggs hatch. They begin their life bright white, nearly translucent. As their cuticle hardens, they become dark brown to almost black, with parallel bands running down the length of their body.

The transition from the nymph to adult stage is a molting period referred to as instar. Roaches will molt their exoskeleton and display their white appearance again until a hormone called bursicon assists in hardening and darkening their shell until the next molt. They will molt up to six times before emerging as an adult in about 60 days.

Adult

After the instar molting period and the completion of their bursicon hardening, the German cockroach will continue to feed and begin to seek out a mate to begin the cycle all over again. As adults, the German cockroach will live up to 200 days.

The overall life cycle will depend on many factors like temperature, location, and food availability. Their ideal conditions are warm and damp. So, when a cockroach enters your home, it thrives in kitchens and restrooms. They are not picky about food and will eat anything and everything. This is why you will find them in cabinets, closets, in between cardboard, in trash cans, in storage items, anywhere, and everywhere. Their greatest threat is human activity.

Can Cockroaches Make You Sick?

Given that they are frequent travelers, are not picky about what they chose to dive into, and can reproduce at an alarming rate, yes, they can be seriously harmful.

Roaches can leave behind casings from molting as well as ootheca. These "dusts" can become an allergen issue for those with sensitivities or those suffering from asthma.

Roaches forage through the filth and can bring that into your home. Walking across counters, tables, and other items you may not see can contribute to the spreading of E. coli and Salmonella.

Roaches will contaminate anything they touch.

How Do I Get Rid of Roaches?

The first thing to help you fight off cockroaches is cleanliness. Roaches are attracted to a variety of smells such as those from trash cans, a sink full of dirty dishes, and unswept floors. These conditions are more favorable when you live in a multi-family housing unit. You may be clean, but your neighbor may not be. All it takes is one night of being too tired to clean up, and you may find yourself with new unwanted guests.

If you do not live in apartments or condos, you will want to check the items coming into your home: Cardboard boxes, new purchases (especially used items,) and anything from somewhere known to have a roach issue. Also, keep areas around your home free of the clutter that attracts roaches.
