How Many Cockroaches Are Left in the World?

Cockroaches are ubiquitous in the world, having evolved over millions of years to coexist with man. Their early travel routes helped spread cockroach species to almost every continent, and they are most common in tropical areas. They can also survive in places where humans have established homes and food sources, making them an important part of our eco-system.

There are more than 4,500 species of cockroaches in the world. Ninety-seven percent of them are found outside human contact, serving as important pollinators of plants and flowers. In addition to their role as pests, cockroaches are also very useful in our environment, as they feed on organic matter and plants.

The two major species of cockroaches are the American and German Cockroaches. Both are common in North America. The American Cockroach is the biggest and most limber species. The Australian cockroach is smaller than the American cockroach and comes from Asia. The Oriental cockroach is the most dangerous and is known to inhabit sewers. Their habit is to sneak into homes and set up camp in places that are hard to find.

Cockroaches are an ancient species that has thrived across the world. They have been found in every continent except Antarctica, and fossil evidence indicates that they have been around for about 300 million years. They are so resilient that they can survive anywhere except the Polar Regions and high elevations.
