Residents beware, two invasive species have been ratted out by the Columbia Shuswap Invasive Species Society (CSISS).
The two species CSISS has identified are the Norway and black rat. According to a press release from CSISS, the Norway rat is native to China and Mongolia. They were introduced to Canada via European settlers during the 1800s and are noted for their large size (up to 21 cm). These large rodents are known to enjoy semi-aquatic habitats such as sewage systems.
The black rat is also known as a roof rat due to their climbing capabilities. These scaling skills have led the rodents to be found in ceilings. While they are not quite as large as the Norway rat, they do reach up to 17.5 cm.
The impact of invasive rats is widespread. CSISS noted that rats can have several litters per year which can result in up to 900 pups per year. Damage caused by rats can include contamination, transmitting diseases and damage to crops.
Executive director of CSISS, Robyn Hooper encourages residents to block off potential entry points and remove and securely store any food or garbage that might attract rats.
