Mice may be small, but they're often easy to detect. They make noises and leave evidence of their presence in rooms where they spend time. As soon as a mouse moves into your house, you're likely to notice signs. Knowing what to look for can help you determine whether or not you have a mouse infestation.
1. If You Hear Chewing Noises at Night
Mice living in homes with humans are most active late at night because this is when the least danger is present. When mice wake up, they eat. People who have mice in their home often hear a chewing noise in the night. This chewing may be the sound of a mouse eating through cardboard, paper, or even drywall.
Mice will chew through obstacles to get what they need. For example, when you hear a mouse eating through cardboard boxes in the kitchen, the mice may be trying to get to your cereal, crackers, or tea bags. If you've discovered that your food boxes appear to have been chewed up, this is likely a problem that has been caused by a mouse.
2. If You See Mouse Droppings in the Home
If there is a mouse in your house, then you'll find mouse droppings in places where the mice are spending time. The majority of their time is spent in sheltered areas and in places where food is present. Common areas where you'll find mouse feces include underneath furniture and behind doors. You may also look for droppings in your pantry, food cabinets, under your stove, and under sinks.
Mouse droppings are approximately 1/4 of an inch long and will be shaped like a grain of rice. They are usually consistent in size and shape. If the droppings are larger, then this could be an indication of a rat in your house.
3. If You See a Nest
A mouse nest can be an indication of a current infestation or may be leftover from an old infestation. Mice will use pieces of paper, insulation, cloth, and tissue to make their nest. If you find a mouse nest, there will likely be a lot of droppings and urine in the area.
Do not disturb the area. Mouse droppings can contain a virus known as Hantavirus, which can be fatal. If you discover a mouse nest in your home, contact a pest control company for proper removal.
4. If You Hear Running Noises in the Ceiling and Walls
If you have mice in your attic or walls, you may hear them running from one location to another in your house. Often mice sound much larger than they really are as they scramble, scurry, and climb. If you hear these noises, then make a note of the location in your home where the sounds are heard so you can report it to your pest control company.
5. If You See a Mouse
If you have mice in your home, you're likely to catch a glimpse of a mouse from time to time. Mice are frequently seen running from one place of shelter to another. For example, you may see a mouse dart from the space under the stove to a space behind the cabinets.
Often, mice will run along the wall instead of running through the middle of the room. Make a note of all areas where you see mice in your home, as your pest control company may leave traps in these areas.
