How To Keep Mice Out Of Your House

Table of Contents

Even hosts have their limits, and you’re never expected to share your home with mice (unless they’re darling pets). Mice can cause untold damage to your home, they carry diseases that can harm your family’s health, and they’re an infestation of noise and unsightly debris. Mice can infest walls, insulation, attics, and ceilings, so what do you do to keep these rodents under control? When looking for pest control for mice, consider these options.

What Attracts Mice To A Home?

Shelter to Feel Safe

Mice will seek out shelter as the cold weather sets in, and they seek out homes for the warmth and food they provide. Because mice are so small, they can squeeze into extremely tight spaces that might be prevalent near storages, attics, and garages.

Food to Eat

Like any living creature, mice require a steady stream of nutrition and resources to keep alive. They’ll stay in any place where food is plentiful, and that means your home.

Materials For Nesting

Mice build nests for their offspring, seeking out softer materials like pet hair, insulation, shredded paper, and anything else they can find.

1. Block All Entry Points

Mouse-Proof Barriers

The second you find any kind of mouse access within your home, use materials to seal it shut and mouse-proof any potential entry points. You can use metal sheeting, steel wool, reinforced plastic or glass, or any other study material that a mouse can’t chew its way through. Caulking a hole or potential entrance is always a good move. If you’ve seen signs of a mouse infestation, block those entry points.

Weather Stripping

Wherever the weatherstripping on your house is worn out, mice will find it. Replace any loose weatherstripping around your home, paying special attention to your windows, doors, foundation, and any other openings or entrances/exits.

Add Screens

You can always add wire screens to open vents, block chimney openings, and close any other gaps. Repair damaged screen doors, and install door sweeps to exterior entrance doors. Any place you can add a screen is a good idea.

2. Keep Your Landscaping Neat

There are a number of ways to tidy up the exterior of your home to prevent mouse infestation, reducing the “welcoming” look of your property for these rodents. You can store firewood away from the house, as well as keep your landscaping trimmed back and away from your home. Don’t give mice a secret entrance to your home by accidentally laying out a red carpet of untidy shrubbery. These pest control tips will keep your home safe.

3. Remove All Food Sources

Move Bird Feeders Far From The House

Tell those pesky mice they’re not welcome by moving any bird or squirrel feeders away from your home’s base and/or siding. Keep your bird feeders near your garden or farther down your property, away from where the mice might make a connection between them and your home.

Seal Pet Food

Seal all your pet food containers, or make sure you properly store all your dry food in airtight lidded containers.

Seal Garbage Bins

Seal your garbage bins and only use lidded garbage cans, especially if you keep your garbage bins outside or in your garage. Tightly lidded garbage bins won’t be able to invite mice with their odors.

Seal Dry Foods

Seal all dry foods, especially if you keep your dry goods in an external storage room or your garage. Keep any open containers sealed or put them in properly lidded, airtight containers.

Clean Floors And Countertops

By keeping your floors and countertops clean and sanitized, you will prevent any unwanted intruders—not just mice, but ants and other pests! Regularly mopping and disinfecting is a great way to keep your house clean and free of rodents.

4. Get Rid Of Nesting Materials

Properly store away your fabric, rugs, blankets, and other potential nesting materials (like scrap clothing or washcloths) in lidded storage bins or other closed plastic containers. Mice seek out these nesting materials regularly, but will also look for cardboard, paper, plastic, or other materials that might regularly end up in your trash or recycling. They will chew things up for nesting materials as well, so it might be a good idea to keep your garbage and recycling bins far from your house.

5. Keep Outside Doors Closed

Outside doors can be an easy entrance point, especially if they are damaged or do not close properly. Keep all outside doors closed at all times, or use screens to prevent these unwanted intruders from finding their way indoors.

6. Set Traps And Bait

If you’ve reached a point of frustration, you can set mouse traps and bait to catch these bothersome rodents. There are many different types of mouse traps out there, as well as both indoor and outdoor traps. 

7. Use Holistic Repellants

There are a number of holistic repellants at your disposal, including peppermint oil, cayenne, cloves, and pepper. You can use essential oils or sprays around areas that have regular mouse traffic, dispersing them and keeping them at bay. Or you can lightly soak some cotton balls and leave those around areas where mice might be entering your home.

8. Adopt An Animal Predator

Cats can be a very effective answer to any incumbent mouse issue. Adopting a cat to reduce the rodent population can be a great idea, as sometimes these predators will whittle down the amount of mice significantly. If your home doesn’t allow cats, or someone is allergic, placing kitty litter around the entrance of your home can sometimes keep mice at bay. Mice might vacate the premises entirely if they smell predator urine or ammonia. If mice get in the house, a cat just might scare them away.

9. Use A Dehumidifier

Dehumidifiers make your home much less appealing for rodents. You can place them in your attic, basement, or in crawl spaces. Oftentimes they will keep these potential mouse habitats entirely free of rodents.

10. Be Mindful Of What You Bring In

When you’re trekking in anything from the outdoors, stay mindful and vigilant. Check holiday decorations, clothing stored since last season, firewood, and anything else where mice could potentially hide.

11. Use Sound With Ultrasonic Repellers

Sound is a very effective way to keep mice away. You can use ultrasonic mouse repellers to deter rodents while also keeping your kids and pets safe. They’re fairly easy to find at any local hardware store, and you can place them where you’ve recently seen mouse activity.
