Whether you've encountered a lone mouse or discovered signs of a full-blown infestation, knowing how to rid your home of mice is crucial. You're not the only one—nearly 15 million people in the U.S. have reported rodent sightings in their homes, according to the U.S. Census Bureau. And mice are more than just a nuisance; they pose significant health risks as well.
As per the Centers for Disease Control and Prevention, mice are known to transmit diseases to humans. Fortunately, there are numerous methods available to remove mice from your home. We consulted pest control professionals to gather the most effective advice for preventing and eliminating mice, while safeguarding your home from these troublesome invaders.

While you might not immediately notice one or two mice, an infestation will make itself known through unmistakable signs. According to Bill Swank, founder of PestSource, 'Scratching noises coming from behind walls, droppings scattered like grains of rice, and a musty odor all point to a rodent gathering in your home.'
Mice are often more dangerous than they’re given credit for. As Bill Swank explains, 'People tend to underestimate the health threats posed by mice. They’re more than just pests; they can carry diseases like hantavirus, salmonellosis, and leptospirosis.' If you suspect an infestation, Sean Thomas, founder of Conquer Critters, shares the signs to look for:
- Mouse droppings, typically found in kitchens, pantries, and along baseboards
- Gnaw marks on food containers or structural materials, including wires or insulation
- Scratching or scurrying noises coming from the walls or ceiling, particularly at night
- A musty scent in confined areas
One of the most obvious signs of mice is actually spotting them. Though small and fast, you may catch sight of a mouse running along a wall or floorboard. They're most active at dusk and dawn, so you’re likely to spot them during those times.
Mice can present various health hazards to humans through direct exposure to their saliva, feces, and even airborne particles. Diseases that can be transmitted by mice include leptospirosis, hantavirus, salmonellosis, monkeypox, and Sylvatic Typhus, among others. Infected mice often do not exhibit symptoms of these diseases.
Indirect exposure can also pose risks, as diseases spread by fleas, ticks, and mosquitoes that feed on mice can result in Lyme disease, flea-borne typhus, Colorado tick fever, plague, and more.
Recognizing Common Mice Entry Points
Mice typically enter homes through tiny cracks and gaps around windows, doors, walls, and foundations. They are capable of squeezing through remarkably narrow openings, needing only a gap the size of a pencil to gain access.
"Windows, doors, foundation cracks, and even utility lines can serve as easy access points for mice," says Swank. "If a pencil can fit through, so can a mouse." Sealing up all cracks around doors, entryways, walls, and foundations with caulking can help prevent mice from entering and stop the problem from worsening.
Effective Methods for Eliminating Mice
If mice have made their way into your home, don’t worry—there are several effective ways to remove them. Traps are among the most straightforward and quick solutions to eliminate mice.
Step 1: Seal Off Entry Points
The first step in preventing mice from infiltrating your home is to seal up, caulk, and patch any holes, cracks, or openings that could serve as entry points. Inspect around windows, doors, and walls, ensuring there are no accessible spaces for mice. While spray foam might help, mice can chew through it. The most effective materials for blocking them are metal screens, mesh, or steel wool.
Step 2: Set Up Traps
To get rid of mice in your home, consider a variety of available trap options.
Snap traps: According to Swank, “Snap traps and electric traps are humane and effective when used correctly.” While glue traps may seem convenient, Swank advises against them due to their cruelty. Snap traps are the traditional choice, employing a spring-loaded mechanism with bait to attract mice. When set up properly, these traps offer a swift and painless death, preventing unnecessary suffering.
Electric traps: Electric traps use bait, such as peanut butter, to lure mice in. Once the mouse triggers a sensor, the trap delivers a quick lethal shock. These battery-operated devices often feature a light to indicate capture, simplifying disposal. They offer a fast, humane alternative for dealing with mice without resorting to more invasive methods.
Live traps: Live traps represent the most humane solution. Mice are attracted to food inside the trap, which then closes without harming them. After capture, you can release the mice in a suitable outdoor location, ensuring no harm comes to the creatures.
If you are considering using chemicals, exercise caution as some can be toxic to both humans and pets. The National Pesticide Information Center warns that even a single dose of rodenticide can pose serious health risks to people, animals, and wildlife.
“Rodenticides can be effective but should be used carefully, especially if children or pets are around,” Swank explains. It is advisable to consult with a pest control professional before opting for chemical solutions.
Step 3: Remove Resources and Spaces that Mice Use for Nesting
Mice prefer dark, hidden spaces that are close to their food supply. As a result, areas like garages, attics, basements, and cupboards are common nesting sites. Ensuring your garage is properly sealed is essential since mice can even crawl under car hoods and chew on wires.
Seal off the back corners of cupboards with duct tape or rodent-specific tape. This special tape is coated with capsaicin, a natural compound found in peppers that mice find repellent.
Trim any plants or shrubs outside your home where mice might seek shelter or build nests. Avoid leaving food outside, including pet food, as it will attract them. Bird feeders should also be secured, as mice can easily access them for food. Additionally, try to eliminate any water sources by turning off irrigation systems and sprinklers when they are not needed.
Step 4: Tidy Up After the Infestation
To properly clean after an infestation, Thomas recommends using a solution of water and bleach at a 1:10 ratio or a household disinfectant like Lysol. Be sure to remove any mouse droppings and sanitize all surfaces thoroughly.
Step 5: Reach Out to a Professional
At times, an infestation may be beyond what you can handle yourself. If you've tried all the previous methods and the issue persists, it might be time to consult a professional pest control service. To find a reliable expert, consider seeking recommendations from friends, family, or neighbors. Many pest control companies offer free evaluations, so it's a good idea to research local options and compare pricing and policies.
How to Keep Mice Out of Your Home
The key to preventing future infestations is to keep your environment clean and well-maintained. Additionally, there are several measures you can take to discourage mice from entering or settling in your home. Experts recommend a few strategies that will make your home less appealing to these rodents.
Utilize Essential Oils
For a natural solution, Swank suggests using peppermint oil as an effective repellent, as mice find its scent unpleasant. Clove is another fragrance that mice tend to avoid. To keep mice away, place cotton balls soaked in these essential oils around entry points and areas where they may create nests, like in cabinets and drawers.
Use Vinegar as a Repellent
Vinegar is another natural deterrent for mice. Thomas recommends soaking cotton balls in cleaning vinegar and placing them in your kitchen, especially in areas where mice are most active.
Adopt a Cat
If you've been considering getting a cat, there's another reason to add it to your list of pros. Cats are natural predators of mice, and their presence can scare them off. Studies have also shown that the mere scent of a predator, such as a cat, can be enough to deter mice. Additionally, research indicates that having both a cat and a dog in the same household is effective at keeping rodents at bay.
Secure Your Trash
Mice are strongly attracted to food, so it's essential to ensure your trash cans are clean and have proper lids. If your cans don't close properly, secure them with bungee cords. Metal trash cans are the best option for keeping food smells contained. Also, be sure to regularly clean the bins to prevent any odors that might attract rodents.
Properly Store Your Food
Mice can chew through almost anything if they catch the right scent. To keep them away, make sure to sweep up crumbs, store food in secure containers, and maintain a clean environment in food prep and eating areas. “Store food in airtight containers, clean up crumbs and spills immediately, and make sure trash bins are properly secured. Regularly inspect and tidy up cluttered areas,” says Thomas.
