Blattella germanica

From one breeding female, as many as 10,000 descendents can result within one year. As such, extremely heavy infestations are not uncommon.

German cochroaches are about 5/8" in length, light-to-medium brown in color, with two dark length-wise streaks on their thorax. Although they have fully developed wings, they rarely fly. Young roaches are smaller, wingless and nearly black in color. Egg capsules are tan in color and less than 1/4" in length.

German cockroaches are mainly noctural and infest areas close to food, moisture and warmth. They are the most common cockroach species found in Ohio apartments, homes, supermarkets, and restaurants. In apartments and homes, they are normally found in kitchens near sinks, dishwashers and stoves, and in bathrooms near any plumbing fixtures.

If one is using publicly available products and they are not working when applied according to the directions, never increase the dosage as they can pose health hazards to humans and pet companions. A professional pest expert should be consulted to determine what method or combination of methods for control will be most effective for the size of infestation, type of building, issues with neighbors who may not be so vigilant against pests, etc., and they have access to a wide arsenal of products available only to licensed professionals.

Controlling German cockroaches is extremely important because they can pose numerous health hazards to humans and their pet companions.

  • Their bodies are known to be host to numerous disease-causing bacteria, protozoans, and virii. A number of forms of gastroenteritis seem to be the most frequently carried diseases on roaches: food poisoning, dysentery, diarrhea, and other illnesses.

  • The microbes that cause these diseases live on the legs of roaches, and are thus deposited as they forage for food, crawl across dishes and silverware, etc.

  • They can contaminate foods with odiferous secretions that affect the flavors of foods.

  • The dust created by cast-off cockroach skins, dead bodies, and cockroach excrement contain numerous allergens which can cause skin rashes, watery eyes and sneezing, congestion of nasal passages, and even asthma in highly sensitive people.

These issues make the removal of cockroach detritis and debris equally as important as cockroach control.
