Suggestions For Sealing Your Home Against Mice

The best way to deal with mice is through prevention. Keeping them out of your house will eliminate the risk of damage from chewing and contamination from their droppings. One vital step in mice prevention is to seal up your house so the pests can't wriggle through small cracks and get inside. Here are some suggestions on how to seal your home to prevent mice

Supplies To Use

Sealing your home has two purposes. It keeps mice out, and it keeps air inside so mice aren't drawn to warmth or food odors leaking through the cracks. You can use caulk to seal up tiny cracks and gaps for the purpose of blocking air leaks that attract the mice. When it comes to sealing gaps to block access, you'll want to use steel products. This could be steel fabric, steel wool pads, steel sheets, or steel cages. Mice can chew through about any type of material, so you want something strong like steel. Canned spray foam insulation may be good for filling gaps to block air, but mice can chew through it, so it isn't the best choice for keeping mice out of the house.

Start At The Foundation

Begin at the foundation of your home and work your way to the roof. Mice are good climbers, so you'll need to inspect your entire home. Look for gaps, cracks, and protrusions for areas where mice can enter. Possible areas include the bottom row of siding, corners of your house where siding meets, pipe and vent protrusions, foundation cracks, gaps under doors and around window frames, cables and pipes leading into your home that act as pathways, holes and gaps in damaged soffit and roofing, and openings in roof vents and the chimney.

Close All Gaps

To close small gaps, stuff steel wool into the gap and seal around the edges with caulk to secure it. Cover larger gaps with small pieces of metal flashing so mice can't squeeze through. The metal, whether it is steel wool or sheet metal, will discourage the mice from chewing on an old hole and making it bigger. You won't be able to plug up some openings such as pipes that vent to the outside or the top of a chimney, but you can buy a metal cage or screen to put on top that keeps the mice from climbing inside them.

Sealing up your home from mice is meticulous work, especially if your home is older and has developed sags, gaps, and rotted areas. However, the effort is time well spent, since sealing not only protects against mice, but will also keep out other animals like rats, squirrels, snakes, and even bugs.
