Mice are small rodents known for their pointed snouts, long tails, and large ears. They are typically light brown to grayish in color. One of the key features of mice is their long, thin tails, which are often as long as their bodies. Mice are agile and can squeeze through small openings, making it easy for them to enter homes and buildings. Look for small droppings resembling dark grains of rice, often found near nesting areas or travel paths. They are nocturnal creatures, most active during the night.
