Key Takeaways

• The black rat, also known as the roof rat, is a widespread and adaptable rodent species.
• Black rats are excellent climbers and have a remarkable ability to infest urban areas.
• They originated from Southeast Asia and have spread to various parts of the world through human activity.
• Understanding the range of black rat populations is crucial for effective pest control measures.

History

The black rat (Rattus rattus), also known as the roof rat, has been a companion of humans for centuries. Originating from Southeast Asia, this species successfully spread to different parts of the world through sea routes during ancient times. They were stowaways on ships, which enabled them to colonize new areas.

Due to their exceptional climbing abilities and adaptability, black rats found their way into urban areas, where they thrived in spaces like attics, roofs, and abandoned buildings. They also established themselves in agricultural lands, causing damage to crops and posing a threat to food supplies.

During the medieval times, black rats were associated with the spread of the bubonic plague, carrying fleas infected with the bacteria Yersinia pestis. This disease caused several pandemics and had a large impact on human history. Although the black rats were not the direct cause of the plague, they played a significant role as carriers of the disease-carrying fleas.
