In this article, we will cover everything you need to know about the Norway Rat in Florida, including its origins, characteristics, habits, and control methods.

Norway Rat

Norway Rat: General Information

The Norway Rat, or “rattus norvegicus” also known as the brown rat, sewer rat, or wharf rat, is a common rodent found all over the world, including Sarasota, Florida. Norway rats are one of the largest rat species, measuring up to 16 inches in length, including their tail. They also have a blunt nose, small ears, and shaggy brown fur with a lighter underbelly. They are well known for their sharp teeth, which they use to gnaw on almost anything, from wood, electrical wires, and AC ducting causing damage to properties and posing a fire hazard.

The Origins of the Norway Rat

The Norway Rat is a species of rodent that is believed to have originated in northern China. They are known for their adaptability and have spread to many parts of the world, including Europe, North America, and South America. The first recorded sightings of the Norway Rat in Europe date back to the 18th century, and they were likely brought over on ships as stowaways.

The Norway Rat’s ability to thrive in a variety of environments and their rapid reproduction rates have made them one of the most successful mammalian species on the planet. They have also been known to carry many health risks as they pass numerous zoonotic diseases.  This has always led to efforts to control their rat populations throughout history.

In the late 19th century, the Norway Rat became a major problem in urban areas, particularly in cities such as London and Paris. It was during this time that public health officials began to understand the connection between rat infestations and the spread of diseases such as the bubonic plague. Efforts were made to control the rat populations in cities, including the use of poison and traps.

Norway Rats: Not from Norway?

Despite its name, the Norway Rat is not actually native to Norway. The origins of its name are not entirely clear, but it is believed to have originated from a misidentification of the rat’s place of origin.

One theory is that the Norway Rat was first identified by European naturalists who believed that it came from Norway because of its thick fur, which is similar to the fur of other animals found in that region. Another theory is that the name comes from the fact that Norway was one of the first countries to implement a successful campaign to eradicate the Norway Rat in the early 20th century.

Regardless of its name’s origins, the Norway Rat has since become one of the most widespread and successful mammals in the world. It is known for its adaptability and ability to thrive in a variety of environments, making it a common pest problem in many parts of the world, including Florida. Despite its name’s inaccuracy, the Norway Rat remains an important species in the study of mammalian ecology and behavior.

        • Mice vs. Rats: Norway Rats are larger than house mice and roof rats and have different behaviors.

        • Norway rats are known for their ability to dig in the ground to get under and around obstacles. 

        • Norway rats also will take up refuge in the sewers and can enter homes through open or broken plumbing in the attic and under homes.  They can enter through the sewer side, the vent side and are even well known to find their way up through the toilets.
