What are the different species of rats - 64 rat species


The rat is one of the most common and successful mammals on earth. Even the rat family tree is impressively large. The rat family is primarily composed of members of the Rattus genus. Members of this genus are also known as old-world rats or "true rats". These aren't to be confused with cousin species like a nutria (Myocaster coypus). We can learn a lot about the species, as well as rodent control measures, by taking a quick look at all the representatives of the Rattus genus. 

black rat

1. Black rat (Rattus rattus

The black rat is the prototypical rat. When people conjure up an image of a rat, the black rat is generally what springs to mind. The black rat originally lived in the western areas of both India and Pakistan. However, over time it's spread to every corner of the earth. The only exception is Antarctica. However, while they have no permanent presence in the region. they have been known to temporarily stow away with humans venturing into those chilly lands.

The brown rat has the honor of being the only rat species to have had a long-term presence on the International Space Station

 A24 Rat Trap

We've learned there are many more species of rats than one would have thought. This was not always the case — these species have evolved over time. Rats have the ability to multiply at an alarming rate, and can quickly spread to new locations. Controlling rats is necessary to keep the species from quickly getting out of hand. With quick-kill options like the A24 Trap, they can be managed without the use of toxins.
