“I called Pest Management Systems, Inc. requesting information about pest services concerning a particular insect I was seeing in my rental property. The receptionist was very knowledgeable concerning the insect with regards to how they breed and their season for egg hatching. She also advised me of alternative approaches to handle the situation. I really appreciate the fact that Pest Management Systems, Inc. did not attempt to sell a service that probably would not have provided the results I wished (like other popular pest control companies in my area attempted to do). I will definitely consider Pest Management Systems, Inc. in the near future. ”

What Do German Cockroaches Look Like?

Adult German cockroaches are recognized by their light brown to tan coloring with two dark, almost parallel stripes, located on their backs. Female German cockroaches tend to be darker than males. German cockroach nymphs are dark brown to black in color with the same dark stripes located on their backs. While German cockroaches have wings, they rarely fly. Instead, they prefer to run.

Signs of a German Cockroach Infestation

German cockroaches prefer to live in warm, humid places close to food and moisture sources. They are frequently found in residential and commercial kitchen environments, and bathrooms, so these are the two most likely places for an infestation to occur. It is also likely to find German cockroach dropping in areas they frequent. Droppings may appear as small, dark, “pepper-like” material left on countertops or in drawers. There may also be fecal staining, which appears as dark spots or smears in the corners of rooms, along the tops of doors or around small cracks and openings into walls.

When German cockroach populations are present in large numbers, it may be possible to detect a mild, somewhat “musty” odor.

German Cockroach Prevention

How to Get Rid of German Cockroaches

The best advice for German cockroach control is to practice good sanitation. To prevent German cockroaches from infesting a home or business, people should maintain a clean kitchen by cleaning up crumbs, wiping spills and vacuuming often. Avoid leaving dishes pile up in the sink. It is also important to seal all entrances to the structure, especially around utility pipes, and ventilate crawl spaces to prevent moisture buildup. If there is evidence of a German cockroach infestation, contact PMi to inspect and treat the German cockroach problem.

German cockroaches can breed at a rate of up to six generations per year, so a treatment plan may be necessary to ensure the infestations remains in check.

Threats

More than just a nuisance, German cockroaches have been implicated in outbreaks of illness and allergic reactions in many people. Cockroaches have been reported to spread at least 33 kinds of bacteria, six kinds of parasitic worms and at least seven other kinds of human pathogens. They can pick up germs on the spines of their legs and bodies as they crawl through decaying matter or sewage and then carry these into food or onto food surfaces. Medical studies have shown that German cockroaches cause allergic reactions and can exacerbate asthma attacks, especially in children. This makes German cockroach control incredibly vital.
