How to Get Rid of Mice Quickly and Humanely

No one wants to share their home with pests, especially mice. These critters might look cute, but they can cause serious damage and carry diseases that risk your family’s health. Here’s how to determine if you have this common pest in your home and how to get rid of mice as safely, humanely, and quickly as possible.

1. Eliminate Entry Points

Mice can squeeze through the tiniest of holes, so eliminating entry points is the best way to keep them from coming in. Start by replacing worn-out weatherstripping around the home; seal minor holes, gaps, or cracks with caulk. Use insulation foam to prevent mice from crawling inside through your pipes. When eliminating entry points, make sure you review exterior ones as well as interior.

2. Use Natural Repellents

Mice dislike several strong scents, so you can use essential oils or homemade sprays to make your home a less appealing shelter for these creatures. 

Some natural mice repellents include:

• Peppermint oil

• Cloves or clove oil

• Cayenne pepper

• Spray made with one part water to one part apple cider vinegar

• Spray made with red pepper flakes, sliced hot peppers, dish soap, and water

Douse cotton balls with liquid repellents and tuck them in corners where you suspect the mice live or frequent. With sprays, apply the spray outside of the house and any entry points inside. Refresh the repellent cotton balls every few days, and respray around the house at least once per month.

3. Set Out Bait and Live Traps

If you’re looking for a DIY method to get rid of mice, set out bait and live traps. You can find a wide variety of humane trap options at your local hardware store to catch and release mice. For bait, use high-calorie sweets. Set up the traps in the out-of-sight areas where mice are most likely to travel.

4. Consider Ultrasonic Devices

Like us, mice want a cozy, quiet place to settle down. Ultrasonic devices are designed to emit sounds that the mice and other pests can hear, creating an unpleasant environment that drives the mice out.

You may want to use these devices along with other repellent measures, like homemade sprays. Ultrasonic devices alone aren’t the most effective mice-removal method because walls and furnishings can block the sound. You can buy an ultrasonic product for about $12 to $50.

5. Properly Sanitize 

Mice love any leftover food they can find, so promptly removing any food scraps and keeping your bins clean may deter them from looking for food inside your home. You can also make sure any leftover food is placed in a container with a tight seal and sanitize all areas they may find crumbs, such as the floors, counters, bins, and equipment.

6. Remove Outdoor Debris

Mice also love nesting in outside burrows, so removing outdoor debris can reduce the likelihood of them coming near your home. Remove piles of leaves, rocks, brush, wood, or long weeds, and keep your yard as tidy as possible throughout the year. Cut your grass regularly and don’t overlook your compost pile—moving the compost as far away from your house as possible can cut down on mice getting too close for comfort.

7. Adopt a Cat

As long as no one in your family has a cat allergy, consider adopting a furry friend to take care of your mice problem. Cats can help catch mice, but their presence is also intimidating enough to turn your home into an unwelcoming shelter for mice. Mice can smell a cat and will be naturally repelled from your house.

How to Prevent Mice

Once you’ve driven the mice from your home, you’ll want to take steps to prevent them from returning. Remember, mice are attracted to your house because they are looking for food and shelter, so make sure you’re not inviting them in with cozy, cluttered places to nest and unsealed food packages around the house.

Remove Food Sources

Mice can chew through cardboard boxes and plastic bags in their relentless pursuit of food. Make sure your family’s food, including pet food, is sealed and cleaned up to keep rodents out.

• Remove flours, cereals, pastas, and other dry goods from their packaging and store them in tightly sealed, reusable glass or metal containers.

• Clean up crumbs and spills from counters, tables, and floors daily.

• Clean your pets’ food bowls after they eat.

• Keep pet food in tightly sealed packages, or consider storing them in an airtight metal pet food container.

Clear Out Clutter

If you’ve been putting off decluttering, take this as a sign to get started. Those stacks of papers or clothing piles make perfect nesting sites for mice. If you want to keep mice away from your home, declutter your house to minimize nesting places and materials for these pests.

Take Out Recycling

Don’t let recycling pile up by the kitchen trash can. The layers of cardboard, mail flyers, and newspapers offer plenty of easy-to-access nesting materials for mice. Clear out the recycling pile daily to prevent mice from nesting in this spot.

Seal Entry Points

In addition to using steel wool to seal any mouse holes, you can also take preventative action by sealing other entrances around the house. Use caulk and weatherstripping to seal doors and windows, and consider using caulk and steel wool or metal sheets around any other gaps or holes. Mice only need openings about ¼-inch wide, so be mindful of sealing any gaps, even if they seem too small to you.

Getting Rid of Mice Yourself vs. Hiring a Pest Control Service

Most DIY mice removal methods and repellants cost about $5 to $50. Live traps start around $5 to $15 each, while ultrasonic devices range from $12 to $50. You can make homemade sprays with chili peppers or essential oils for a low cost, especially if you already have the ingredients on hand. 

But homemade solutions aren’t always effective, especially if a large family of mice has made your house their home. If you suspect a large infestation or DIY attempts aren’t doing the trick, you’ll need to hire a pest control service as quickly as possible. Professional pest control for mice costs about $200 to $600. You can hire a local pest inspection specialist to survey your home and provide a free estimate for removal services.

• Live traps: Pest control offers live trapping and relocation for larger pests, like rats, starting at about $50 per animal.

• Exclusion: The company will seal entry points for around $200 to $600.

• Fumigation: Fumigation is a last resort for infestations that have become out of control. Fumigation services cost about $1 to $3 per square foot.

• Ongoing service: You may request ongoing inspections and treatments monthly, quarterly, or yearly for $40 to $550 per visit.

Signs of a Mice Infestation

When you have mice in your home, you’ll know it. Aside from seeing mice outright, there are many tell-tale signs you have mice.

• Droppings: The unpleasant reality is that mice will leave droppings around the house. Mouse droppings are about ¼-inch long, while rat waste is typically larger.

• Holes: You may see holes along baseboards, usually in places near food like kitchens and pantries. A mouse hole can be as small as the width of a pencil.

• Sounds: If you hear scuttling around the room or in the ceiling, you may have mice or other pests in the house.

• Musky smells: Like droppings, mice need to excrete urine, leaving behind an acrid or musky scent similar to ammonia or damp wood.

• Damaged food packaging: If you find holes or tears in your snack bags, toss it immediately, as this is a common sign that mice have been into your food.

• Mice sighting: Another clear sign of mice? You see one (or more)!
