You might be surprised to know that a little house mouse can make a mighty big ruckus, and their favorite time to do this is usually when you’re looking for a little peace and quiet. We’ve got answers to your questions like: when do mice sleep, where do mice sleep, and what to do if there’s a mouse in the house?

Are mice nocturnal?

Just like you and me, mice need to sleep, but their sleeping habits are a bit different than ours. When it comes to the question of mice being nocturnal, or most active at night, the answer is complicated. Their sleeping habits depend on the environment of the mouse.

Mice are most active when the least danger is present. For mice in the wild, they are usually most active around the hours of dusk and dawn. The low light conditions at these times offer mice the most protection from predators. However, a house mouse is usually most active at night, when the people of the house are sleeping.

Mice have very poor eyesight and are sensitive to bright lights. This is another reason why the dusk and dawn hours are prime time for rodents. Instead of relying on their vision, mice use their sense of touch and smell to find their way around, making it easier to navigate even in the dark.

Where do mice sleep?

Mice tend to maintain a small territory, usually traveling only 10-30 feet away from their nest for food. They sleep in a nest they make from any materials they find. Things such as stuffing from a pillow, blanket, or stuffed animal all work well, but as mentioned earlier, they can also shred different items with their teeth to make it suitable for nesting.

A cluttered area with junk mail, cardboard boxes, or other scrap materials is a dream home for a mouse. Not only will it be harder for you to notice them, they will have plenty of places to build a cozy nest where they can sleep soundly and get everything they need.

Are mice sleeping in your home?

Since mice tend to be nocturnal, how do you know if your home has a mouse problem? You may not see an actual mouse in the house, but you will see signs of mice. Here’s what to look for to help you sleuth out a sneaky pest problem:

  • Droppings: Mice aren’t potty trained and they’ll leave their droppings behind to let you know they’re here. Look for small black pellets, similar in size and shape to rice.mouse_chewing_on_wires-thumb_.jpg
  • Gnaw damage: Mice chew constantly. One reason they chew is because their teeth never stop growing; they need to gnaw to wear down their teeth. Other reasons mice gnaw on different materials is to make soft bedding for their nests, to sample different foods, and to create entry or exit points.
  • Smudge marks: As mentioned above, rodents rely heavily upon their senses of touch and smell to navigate. In the process of feeling their way around, they leave greasy rubbings or smudge marks along frequently traveled paths. These marks also contain scent markers, or pheromones, that are only detectable to mice. Look for these markings at ground level, along baseboards, door frames, and furniture.

Knowing more about the habits of mice can help you fix and prevent these pests from living in your home. You don’t have to keep losing sleep over these freeloading houseguests. Learn about the what mice eat to help clean up what attracts mice the most.
