To determine if the droppings you’ve found are from a rat, consider their size, shape, and appearance. Rat droppings are typically about 1/2 inch long, with blunt ends and a smooth texture. They are usually dark brown or black in color. Additionally, the droppings often have a slight sheen when fresh. If you notice these characteristics along with a presence of a strong, musky odor nearby, there is a good chance they are rat droppings. It’s also important to look at the location: if they are found in areas like basements, attics, or near food sources, it further indicates that they could be from a rat. Always exercise caution when handling suspected rodent droppings, as they can carry diseases. If you are unsure, consider consulting a pest control expert for a proper assessment.
