The American Cockroach has a reddish brown color, and they are very large. They are normally 1 to 1.5 inches long. You can identify American Cockroaches by looking for lighter-colored edges around the body. Additionally, their wings appear larger than the body.
You’re most likely to find the American Cockroach in warm, moist locations. Inside the home, they like to hang around sewers, basements, bathrooms, and other areas where moisture piles up. These cockroaches specifically like to breed around sewer facilities, but they will venture into other buildings for more networks. This explains why American Cockroaches are an issue for old row homes.
The German Cockroach is a smaller species. It is only 1/4 to 5/8 of an inch, and it is light brown or tan. An identifying characteristic of the German Cockroach is that it has dark stripes placed along the length of its head.
German Cockroaches are often misidentified as Asian Cockroaches. The species looks very similar and is about the same size. You can separate a German Cockroach from an Asian Cockroach by its flying patterns. German Cockroaches mainly scurry and are poor flyers. Asian Cockroaches, in contrast, are fantastic Flyers and choose to fly away.
Because of their size, German Cockroaches like to live in small cracks or crevices. They flock to moisture, but they will hide out in small crevices around the moisture. When infestations begin, German Cockroaches stay in cracks along the bathroom or kitchen. The infestation can escalate so that the cockroaches are found throughout the entire home.
If you find a German Cockroach in your home, it’s important to act fast. This cockroach species is the most common in homes and commercial locations because they are one of the most invasive species. They can be found in basically every structure where humans live and are adaptive to changing environments. They are even good at catching a ride on unsuspecting hosts.
Even though German Cockroaches can’t adapt to most environments, they prefer areas that have boxes, bags, and other safe places to hide.
A single female German Cockroach can have up to 40 eggs at a time, and she can produce three or four generations every year. Because of how quickly German Cockroaches reproduce, just a few cockroaches can turn into a full-blown infestation in just three months.
