Different types of cockroaches exist apart from the common American Cockroaches. Some are scavengers, omnivorous, and opportunistic while others favor a certain type of food.
Cockroaches can be some of the most important home pests. They can also carry viruses and bacteria such as Salmonella.
Various types of cockroaches live around the world. Many of them have spread from a specific habitat together with various industries and with travelers.
Not all cockroaches have the same size, color, and habitat. Different attributes make each species different and some species similar.
Roaches are often associated with American Cockroaches which measure up to 1.6 inches. German Cockroaches measure around 0.5 inches while some of the smaller roach species barely measure 0.2 inches.
Most cockroaches in North America measure anywhere between 0.2 inches and 1.6 inches as adults.
Cockroaches can be brown, red, red-brown, dark brown, or black. Some may also show yellow or cream-colored margins.
Cockroaches live almost anywhere. Some species are tied to human settlements while others may live in woodlands.
Only a small number of cockroaches are actual home pests as many prefer to live outdoors.
Types of Cockroaches
Here are some of the most common cockroach species in North America and around the world.
1. American Cockroach
American Cockroaches (Periplaneta americana) are some of the most common types of roaches in the world. Unlike their name suggests, they are of African origin with an introduced status in the United States.
These cockroaches have a size of around 1.6 inches and a red-brown color.
American cockroaches can grow to a maximum size of 2.1 inches, being larger than other common species such as the German Cockroach and the Oriental Cockroach.
They are seen as pests in many parts of the world due to their omnivorous diet. They feed opportunistically which means they can feed on new items and different types of food daily.
These roaches feed on decaying or fermenting food. They eat bread, human hair, pieces of leather, carcasses, pieces of paper, and feces.
Diseases and viruses are spread by these cockroaches when they come in contact with food.
2. Smoky Brown Cockroach
A dark brown color is specific to the Smoky Brown Cockroach (Periplaneta fuliginosa). While related to the American Cockroach, this species has distinct traits when it comes to temperature preferences.
Smoky Brown Cockroaches are among the species that love warm climates. They only live in Southern US states, Australia, and Japan.
Roaches of the species cannot survive cold weather outdoors. They might be able to survive indoors, but they can be looking to move out for moisture.
Smoky Brown Cockroaches move indoors and outdoors at night, due to high humidity preferences.
Dependent on warmth and moisture, Smoky Brown Cockroaches are just as detrimental as pests as the American Cockroach.
An omnivorous and opportunistic diet means Smoky Brown Cockroaches can spread diseases, mainly from feces.
3. Oriental Cockroach
Larger than the German Cockroach but smaller than the American Cockroach, the Oriental Cockroach (Blatta orientalis) grows to a size of up to 1.14 inches.
These cockroaches have an almost black color and the tendency to only come out at night.
Many infested homes may appear roach-free during the day as these cockroaches hide during the day.,
A preference for high and very high humidity is attributed to the species.
This is one of the reasons why the species is seen around piping, sewers, drains, and under mulch or leaves.
The types of cockroaches can spread bacteria and viruses.
They are seen as major home pests in almost all areas of North America except some of the Eastern states.
4. Pale-bordered Field Cockroach
These types of cockroaches (Pseudomops septentrionalis) have contrasting bright margins which inspire their name.
Pale-bordered Field Cockroaches are considered more beautiful than other species given their pale margins and their dual color body.
These cockroaches may sometimes grow up to 1 inch but many remain smaller, measuring around 0.5 inches.

The species is a scavenger and an opportunistic eater with the tendency to favor meats and decaying meats for food.
Fat-rich foods also attract this roach. It can be a major pest in the kitchen or restaurants.
High numbers of these cockroaches are seen in case of home invasions, mainly because it has no real predator once settled indoors.
8. Pennsylvania Wood Cockroach

Native to Africa, the species is now established on the Eastern Coast of Australia where it mostly lives outdoors.
With a preference for plants, the species lives outside of the house in warm climates as it cannot survive cold climates.

A high preference for moisture under mulches is specific to the species.
Mostly interested in plants, these types of cockroaches rarely get indoors.
Due to being a few times smaller than most other pest roaches, it can be difficult to keep all Three-lined Cockroaches out of the house.
16. Virginia Wood Cockroach
Native to Eastern US territories, the Virginia Wood Cockroach (Parcoblatta virginica) is a species of brown and dark brown roaches.
It lives in woodlands preferring to feed on various types of vegetation, particularly decaying vegetation.
Virginia Wood Cockroaches may sometimes be confused with American Cockroaches based on their size.

The pest status of the bug also differentiates it from American Cockroaches. Most Virginia Wood Cockroaches live outdoors.
Only homes close to woodlands might attract occasional Virginia Wood Cockroaches.
17. Asian Cockroach
A tan to brown color makes the Asian Cockroach (Blattella asahinai) a similar species to The German Cockroach.
This species is seen in North America, with a considerable Florida presence.
