Of all the pest problems that may arise, mouse and rat infestations are among the most common. Rodents are known for taking residence in homes and businesses in search of food and shelter. Unfortunately, it’s not always easy to identify the presence of mice and rats until an infestation is well underway. These rodents are incredibly intelligent, making them superb hiders. However, if you are diligent and know what to look for, you may be able to quickly identify signs of mice and rats before you have a severe case to treat.
