Over 3,500 different types of cockroaches exist throughout the world. Out of all these cockroach types, roughly 69 cockroach species exist in the United States. While 69 might still seem like a big number, Americans only have to worry about 5 or 6 specific cockroach species. Some will worry more than others, depending on the state they live in.
5 Common Types of Cockroaches
1. German Cockroaches
These indoor cockroaches are known to most people throughout the world. Adult German cockroaches have a tan or light brown coloration to them. They also have 2 black horizontal stripes that run down behind their head in the pronotum region. German cockroaches can grow as long as 13 to 16 millimeters. The younger small cockroaches called nymphs have a dark color that almost looks black. The back of their heads also has black stripes too. You can find this species all throughout the United States, especially within structures which have humid and warm conditions. This includes kitchens and bathrooms mostly, but they will also inhabit bedrooms and living rooms where people tend to drink and eat.
The most common cockroach is the German cockroach, which is also the most important cockroach. They tend to be linked to outbreaks which cause people to have allergic reactions and illnesses.
2. American Cockroaches
American cockroaches have a reddish-brown color to them along with a yellowish pattern of a “figure 8” on the backs of their heads. American cockroaches are found all around the United States and they live mostly in basements and sewers, especially in moist areas like drains and pipes.
Out of all the cockroaches that infest homes, the largest is the American cockroach. They inhabit environments that are warmer than 70°F. However, under the right conditions, they can survive colder temperatures too.
3. Oriental Cockroaches
Oriental cockroaches exist in the northern section of the United States. They have a very dark and shiny appearance to them. You’ll typically find them living in the sewers or getting into homes through the drainage system. Once inside the home, they’ll typically stay in the crawl spaces and basements. If you have firewood or piles of leaves outside, they will stay in there as well. Oriental cockroaches are sometimes referred to as “water bugs,” since they tend to crawl out of drains in homes. They are also called black beetle cockroaches due to their dark smooth bodies. You’ll know an Oriental cockroach when you see one because they give off a strong smell. This is why they are considered to be one of the dirtiest cockroaches in existence.
4. Smoky Brown Cockroaches
In the southeastern region of the United States, the smoky brown cockroach is a frequent pest on people’s property. Most of these cockroaches are located between central Texas and North Carolina. Some people have spotted them in Illinois and Indiana as well. The smoky brown cockroach is named after its brownish-black exterior. It is primarily an outdoor cockroach and can get as long as 38 millimeters. They are also very good fliers and have wings which can extend far out beyond their own bodies.
5. Brown-banded Cockroaches
The brown-banded cockroaches, also known as Supella Longipalpa, can get as long as 13 millimeters. The females of the species have wings that are kind of reddish-brown and dark brown. The males of the species have wings that are dark brown in the base area but when they extend their wings, they tend to lighten up. Males are the only ones of the species that can actually fly. The females and males of the species have 2 light-yellow bands that stretch across the shape of their bodies. When they are disturbed, the cockroach will jump. They usually live for an average of 3 months to 11 months.
These cockroaches like to exist in drier and warmer locations that are high up. You’ll likely find them in upper cabinets, kitchens, bathrooms, and upper floor rooms. They like to hide their egg cases underneath or inside of furniture.
