If your home is infested with rodents, there are several signs that rats or mice have taken up residence in your home. One of the best ways to identify a rodent problem is to look for mouse droppings. Typically, mouse droppings are about the size of a grain of rice. These nasty pellets are black or brownish in color, and are often grouped in one or more location throughout the home.
