Rat Habitat
Norway Rat Crawling Near Oven
Rats are highly adaptable creatures that can thrive in a wide range of environments. The two most common species in North America, the Norway rat and the roof rat, have distinct preferences when it comes to their habitats and nesting. Norway rats generally build their nests in burrows close to the ground, often near buildings, sewers, or under piles of debris. Roof rats, on the other hand, prefer elevated spaces like attics, trees, or rafters. Identifying nesting habits reveals where they tend to settle and reproduce.
Where do rats live?
Norway rats and roof rats, while often found near each other, prefer very different habitats. Norway rats, also known as brown rats, are burrowers by nature and thrive in low-lying areas. They favor environments close to the ground, such as basements, crawl spaces, sewers, or outdoor burrows near buildings and gardens. On the other hand, roof rats, or black rats, prefer higher ground. These agile climbers often nest in attics, roofs, trees, or dense shrubs and are particularly drawn to areas with plenty of cover and access to food sources. Both species are highly adaptable, making them regular tenants in urban and suburban settings where human activity provides ample shelter and sustenance.
Rat Nests
Rats aren't just looking for a free meal; they're also looking for a place to call home. Both Norway and roof rats are resourceful builders, using whatever they can find to create a cozy (and destructive) nest.
Norway Rat Nests
Norway rats are expert burrowers. They build their nests by digging into the soil, often under buildings, in gardens, or along foundation walls. To make it feel like home, they line their burrows with soft materials like shredded paper, fabric, or grass.
Roof Rat Nests
True to their name, roof rats prefer a room with a view. They build their nests in high-up places like attics, wall voids, or trees. Roof rat nests are usually messy-looking balls made of twigs, leaves, and other debris, keeping them hidden from predators and people.
Because rats reproduce so quickly, what seems like a minor issue can escalate into a major infestation before you know it. If you've seen signs of rats like droppings, gnaw marks, or nests, it's time to call in the professionals. Orkin Pros are trained to identify the specific species, locate nesting sites, and implement an effective rat control plan to protect your home and family. Call your local Orkin branch for help getting rid of rats in your home.
More Rat Information
Rats form social hierarchies in large populations, with dominant males mating first. They are aggressive when threatened, display defensive postures, and avoid unfamiliar objects, making them hard to trap.
Rats dig burrows with multiple entrances near food sources, often in soil along foundations, gardens, or under debris. Norway rats create extensive tunnel systems, while roof rats nest above ground.
