Things to know about the German Cockroach

There are more than 3500 species of cockroaches in the world. Two main species found in the UAE – The American Cockroach (Periplaneta Americana) and the German Cockroach (Blatella Germanica).

Cockroaches, in general, are flat and oval with six legs and a pair of antennae. German cockroaches range in size from ½ inch to 5/8 of an inch long. They are light brown to tan in color and often distinguished by two dark stripes down their back.

The German cockroach loves a hot and humid environment, such as a kitchen. German cockroaches are fully winged but rarely fly, and are mostly active at night, so unless you know the danger signs, you may not even know you have them! If you suspect you may have cockroaches in your house take a peek inside a warm, dark crevice… if you dare!




  1. German cockroaches do not just nibble on crumbs found in the kitchen, they will eat almost anything, and by anything, we mean anything - hair, glue, soap, and toothpaste.
  2. Female cockroaches protect their eggs by putting them into a thick protective case that is called an ootheca. One female German cockroach can place 40 eggs in one ootheca. That is many cockroach babies!
  3. Can they bite? Well, they are omnivorous - meaning, they consume vegetarian as well as non-vegetarian food with equal aplomb. They can be typically attached to starches, fatty foods, meats, and sugars. In cases of foodstuff shortage, these insects can live on household items like toothpaste, soap, glue, etc. Under conditions of famine, they can turn cannibalistic as well. In such a case, they may start chewing up legs and wings of each other. Hence, their dietary range is quite varied and extensive, and it completely depends upon a prevailing dietary and environmental condition.
  4. German cockroaches are able to climb on smooth surfaces because they have a sticky pad on their feet; this sticky pad is called an arolium.
  5. German cockroaches are more than just nuisance pests – they have been linked to disease transmission by picking up germs on the spines of their legs as they crawl through decaying matter. These germs are then transferred to food and other common surfaces that humans frequently touch. In fact, cockroaches are known to spread at least 33 different types of bacteria, six kinds of parasitic worms and at least seven other human pathogens
