A very common species of rat is the Norway rat, a brown/grey rodent that can reach up to 10 in. (25 cm) in size and weigh about 12 oz. Norway rats tend to reside in moist environments such as riverbanks and sewers and are great scavengers and swimmers.
Norway rats are known to carry parasites and disease-causing bacteria and will eat anything they can get. They breed quickly, so it is imperative that you contact Miller Pest & Termite to send a professional to your home to exterminate any rats before the infestation grows.
