Will Steel Wool Stop Mice?

Steel wool is a product you’re likely very familiar with already.

This very same product can be effective when it comes to keeping mice out of your home.

The major issue for most homeowners is that cracks in and around your home can allow mice inside, allowing them to breed in your home and create a colony-like environment. How do mice get in house? Read here.

If you don’t have a lot of mice in your home now, or you’re simply trying to keep the ones you see outside from getting inside, steel wool can be an effective option.

  • Steel wool can keep mice from entering your home through tight spaces that can be problematic, especially in older homes.
  • You’ll need to remain vigilant when using steel wool, checking areas where you apply this treatment regularly.
  • You may need to replace steel wool over time to keep mice out. Steel wool is not a long-term solution either, so it’s best to keep an infestation or problem you’re having outdoors from coming inside for a short period of time only.

Standard Products

Many pest control products made of steel wool exist, but you can create your own pest control product with regular steel wool if you prefer. Synthetic Steel Wool by 3MThese products are easy to find and can be purchased at almost any grocery store as well, allowing you to act quickly even if you can’t find specialty materials the same day you spot a problem.

A variety of brands of steel wool exist, including products from companies like 3M, Homax and more. Your local hardware store will likely also carry a store brand.

When shopping for standard steel wool, keep these considerations in mind:

  • Heavy steel wool – grades #2, #3 and #4 are the stiffest and hardest, making them the most difficult for pests to chew through. Heavy steel wool is harder to work with though, making it best for large cracks and gaps where extra flexibility isn’t required.
  • Lighter steel wool – grades #0000 to #1 are more flexible, making them easier to put into small 1/4” or 1/2” sized cracks where mice might get into your home.
Steel wool can get into your eyes causing great irritation when you’re cutting or shaping it to fit into cracks or holes in walls, garage doors or window sills. Always wear eye protection to stay safe when working with standard steel wool or specialty products.

How to Use

Steel wool, from the outside, seems like a product that would be better suited for washing dishes than tackling tough rodent problems in your home.

There are many ways to use steel wool products and standard steel wool to keep mice out of your home:

  1. Use steel wool products or standard steel wool to fill cracks in walls, window sills, garage doors and any area larger than 1/4″ where mice can get in. Even small holes and cracks can become a problem when mice begin gnawing in the area to get inside your home.
  2. Place steel wool into cracks and use caulk to seal it into place. This helps fill the steel wool, turning it into a product that mice can’t gnaw through or eat. Adding caulk to your steel wool filled areas also means that you’ll deter mice without killing them since they won’t be able to eat the steel wool and bleed internally.
  3. Check cracks and areas where you’re using steel wool or caulked steel wool regularly. Mice can dislodge steel wool, causing it to be less effective the next time a rodent wants to get into your home. Replace damaged steel wool right away.
