What is a primary characteristic of Norway rats?

• A. They have longer tails than their bodies
• B. They usually nest in trees
• C. They weigh around 1 oz
• D. They usually nest in the ground

Answer: (D)

Norway rats, scientifically known as Rattus norvegicus, are indeed known for their preferred nesting sites, which is primarily in the ground. This characteristic distinguishes them from other types of rats that might prefer higher spaces for nesting. Norway rats typically construct their burrows in soil, often near water sources or in urban areas, which allows them easy access to food and shelter. They are adept at digging and can create extensive burrow systems, which provide not only a place for nesting but also safety from predators. Understanding this behavioral aspect is crucial for pest control and extermination efforts, as it helps in identifying where to target for effective management.
