How Do I Keep Mice Out of My Mattress?

Will Mice Bite You in Your Sleep?

Do mice bite in your sleep? Mice rarely bite people. This is because they are afraid to get near threatening large bodies. They may still make contact with you while looking for food in your bed.

Will Mice Come Near Me While I Sleep?

Yes. There is a chance when you are sound asleep and motionless that a mouse could crawl on you while you are in bed. If the fastest way to get from your bed to their nest or hiding space is to crawl over you, they will do it.

You may awaken suddenly from the sound or feeling of a mouse using you as a bridge between their nesting place and their mission to find food or nesting materials in your bed.

What Time Do Mice Come Out at Night?

Mice tend to be nocturnal and that means that while you are asleep, they are active. Mice will come out at night once you turn off the lights. You will not see mice scurrying around much during the daytime.

If a mouse has its nest disturbed or is actively seeking food, you may quickly see small little pests darting from one direction to the other. At night, a mouse can roam around freely without the threat of you moving around and possibly catching it.

8 Signs That Indicate Mice Have Been In Your Mattress

Here are some signs that can clearly indicate that you may have mice living in your mattress:

  1. You are seeing holes in your mattress the size of a dime.
  2. There are shredded materials like bits of scrap paper on your bed.
  3. You are seeing gnaw marks on your bed posts.
  4. There are small droppings the size of a quarter inch that resemble dark grains of rice.
  5. There is a musky ammonia smell that indicates rodent urine.
  6. You hear scratching sounds.
  7. There are grease marks or tracks on the walls, floors and mattress from mice fur brushing against these surfaces.
  8. You see insects in your bed.

Mice may arrive because they are attracted to these insects as potential sources of food.

How To Keep Mice Out Of Mattresses

Keeping mice out of your mattress involves a few stages:

  1. First of all you need to clean your mattress more often. There are professional mattress cleaning services that can help you to deep clean inside your mattress.
  2. Wash your bedding thoroughly and sprinkle baking soda over all linens and mattress. You can vacuum up the baking soda easily on top of your mattress and you can wash your linens with it.
  3. The bedroom must remain as clean as possible with clothes or other items stored away.
  4. There should be no crumbs of food in your bedroom.
  5. Any holes, gaps, cracks and crevices must be sealed to prevent access points for mice that can easily fit through.
  6. A mouse can get inside a gap that is less than 0.8 inches in diameter. Since mice climb up the legs of your bed, it is a good idea to wrap metal or aluminum foil around it. This will make it harder for them to climb or gnaw on bedposts.
  7. Finally, use a mattress protector as a powerful deterrent to keep mice away from the multiple layers of your mattress. Even though mice can chew through these protectors, some are thick enough to deter them from a useless task if there are no nest building materials or crumbs of food underneath.
