Norway Rat

The Norway rat, also known as the brown rat (Rattus norvegicus), is one of the most widespread and adaptable rodents in the world. Originating from northern China, these rats have successfully colonized almost every continent, thriving in diverse environments ranging from urban areas to rural farmlands. They are medium-sized rodents with a robust body, measuring about 9 to 11 inches in length, excluding their long, scaly tail. Their fur is usually brown or grey, and they have small, round ears and a blunt nose.

Norway rats are notorious for their intelligence and ability to survive in harsh conditions, making them common pests in human habitats. They are omnivorous, with a diet that includes grains, fruits, insects, and even small animals. Their presence can lead to significant health concerns, as they are carriers of various diseases such as leptospirosis, salmonella, and hantavirus. To prevent infestations, it is essential to maintain cleanliness, secure food sources, and seal potential entry points into buildings. Effective pest control often requires a combination of traps, baits, and professional extermination services, particularly in severe cases. Understanding the habits and biology of the Norway rat is crucial for managing and mitigating their impact on human environments.
