How can one accurately identify rat scat through visual inspection and other methods?

To accurately identify rat droppings, also known as scat, one can look for small, dark pellets that are typically about the size of a grain of rice. Rat droppings are often tapered at the ends and have a rough texture. Additionally, one can use a black light to detect urine stains left by rats, which will glow under the light. It is important to wear gloves and a mask when handling rat droppings to avoid potential health risks.
