When you think of areas where rats nest, you’ll likely think of places around human homes. This includes attics, basements, or garages.

There are around 56 known species of rats in the world. As a result, different species may nest in other areas. However, overall, it has been observed that rats are secretive nesters. They will build their nests in quiet, protected areas that help them hide from predators.

When a rat is building its nest outside and not in a human area, it will often choose two main locations. The most common is a burrow dug into the ground. However, they may also nest in small cavities in trees and similar areas.

What Does a Rat Nest Look Like?

While it may seem surprising, a rat’s nest will look quite similar to a bird’s. They have a round, cup-like shape. Often, the physical structure of the nest comprises twigs, leaves, and artificial materials. Their primary focus is on soft materials, so that they may use cardboard, paper, or cloth.

Usually, however, you will not see the nest itself unless you are looking for it. As mentioned above, rats often form small burrows. It is inside these burrows that they will build the nest structure itself. As a result, the outside of a rat’s nest may appear to be a hole. They may also build their nests in tree cavities.

Rats are long-tailed rodents in the order Rodentia. Within this order, they can make up various genera, depending on the exact type of rat. When you think of the average rat found worldwide, you’re most likely thinking of either the black rat (Rattus rattus) or the brown rat (Rattus norvegicus). Whereas many rats are endemic to their native lands, these species have been introduced worldwide for the most part.

Almost all species of rats are nocturnal. Illinois has the most rats in the United States, followed by New York and California.
