German Cockroaches

The German Cockroach is by far the most common and important of the species that are infesting our houses, apartments, restaurants, hotels, and other institutions throughout the United States.

How To Identify a German Cockroach:

As an adult, their coloring is pale to medium brown and they range is sizes from half an inch to 5/8 inch long. Their nymphs are very similar to the adult, with the lack of wings. They are also smaller and darker in color- being almost black. Males have a slender abdomen than the females and are most active. All adults have two dark stripes on the anterior, dorsal portion of their body. Adults of both sexes have wings, but never fly.

Habits of Adults & Nymphs:

Habits of both the adult and nymphs are very similar. Most of their activity takes place at night. If you happen to see them out during the day, this may  indicate a few things: stress, the population is so heavy that there is no more room in cracks and crevices for them to hide or that food and moisture are in short supply. In some cases, if found outside during warm months, it is usually because the infestation indoors is heavy. This infestation needs to be addressed immediately.

German Cockroaches are very active and can fit through very small openings. They are transported through many different ways such as, potato sacks, beverage cartons, handbags, and even in the folds of clothes.

Five Reasons The German Cockroach is Such a Pest:

  1. German Cockroaches produce a larger amount of eggs than any other species that infests structures.
  2. From hatching to sexual maturity, the German Cockroach has the shortest time period of development. This means that the population will build up faster than other species. These two factors combined are called a high reproductive potential.
  3. As nymphs, they have a better chance of survival than any other species because the female will carry the capsule the entire time the embryos are in development. This results in avoiding hazards in their environment and thus, are more likely to hatch.
  4. Due to the size of the nymph, which is much smaller than other species, they are able to conceal themselves in areas that are not accessible to individuals or larger species. For example, in a “commercial kitchen, there could literally be thousands of cracks and crevices where German Cockroaches can hide and remain protected.”
  5. Nymphs tend to stay close to one another, as well as, a female. This creates a high local population density. They also put off a pheromone that is associated with their fecal matter that increases the amount of “clumping” in an area.
