24 Types of Cockroaches (Pictures And Identification)

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.

Cockroach Identification

Not all cockroaches have the same size, color, and habitat. Different attributes make each species different and some species similar.

Cockroach size

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.

Cockroach colors

Cockroaches can be brown, red, red-brown, dark brown, or black. Some may also show yellow or cream-colored margins.

Cockroach habitat

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 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

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

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

Pale-bordered Field Cockroach

These types of cockroaches (Pseudomops septentrionalis) have contrasting bright margins which inspire their name.
