Mice strongly dislike pungent, overwhelming smells like peppermint oil, cloves, cayenne pepper, eucalyptus, and vinegar, as well as predator scents like ammonia, because these mask their own trails and trigger alarm signals, with essential oils or spicy powders applied with cotton balls or sprays being common deterrents, though they require frequent reapplication.
Cinnamon – The strong, spicy scent of cinnamon can overwhelm a rodent's strong sense of smell. Cloves – The intense, spicy fragrance of cloves can be irritating to pests and drive them away from treated areas. Eucalyptus oil – The menthol-like aroma of eucalyptus can be too strong for these little critters to tolerate.
Peppermint oil is one of the most popular scents that deters mice because it's natural, easy to find, and pleasant to humans. Homeowners usually soak cotton balls with the oil and place them in cabinets, under sinks, or near suspected entry points.
Eliminate attractants by storing food in airtight containers, sealing trash, cleaning up spills, and reducing outdoor food sources. Reduce nesting opportunities by decluttering garages, attics, and basements, and removing soft materials (paper, fabric, insulation) that mice use to build nests.
To get rid of mice fast, combine immediate trapping with long-term prevention by sealing entry points (using steel wool/mesh), eliminating food sources (cleanliness, sealed containers), and using deterrents like peppermint oil or cayenne near trails; snap traps with peanut butter are effective, but for severe infestations, professional pest control is best.
To 100% get rid of mice, you need a multi-pronged approach: Exclusion (seal all entry points with steel wool/mesh), Sanitation (remove food/water sources), and Trapping (use many snap traps with peanut butter along walls). For persistent issues, consider professional help, but combining sealing gaps, eliminating food, using strategic traps/bait stations, and maintaining cleanliness offers the best chance for complete eradication.
How to get rid of mice in your house
Learn about mice and their top predators in the wild and in urban environments.
Under or behind kitchen cabinets and appliances, inside or under bathroom cabinets, inside old cardboard boxes, in water heater closets, between ceiling that are near heat sources, under furniture, inside upholstered furniture voids, and in corners of an undisturbed room with lots of clutter.
When you hear scratching, it's usually mice busily navigating the hidden parts of your house, searching for nesting materials or food. These sounds are most often heard during the quiet of the night, when mice are most active and when your house is at its quietest.
The theory is that mice have a strong aversion to the scent of peppermint, which overwhelms their sensitive noses and drives them away. Placing peppermint tea bags in areas where you've spotted mouse activity could provide a mild deterrent, but don't expect it to solve a serious infestation.
Scientifically, none of these oils, dryer sheets or pine sol work at repelling mice and it's proven that it doesn't work. Not sure why so many people keep using them. It's true that mice don't like the smell of peppermint, but you would have to keep a 50 gallon batch to continuously apply it because it doesn't last.
“The strong menthol aroma of peppermint oil makes mice particularly uncomfortable,” Liakopoulos says. Soak cotton balls in the essential oil and place them around your home to ward off rodents. You can also put a few drops of peppermint oil in your homemade cleaning solutions to keep the scent fresh around your house.
In the spring and summer when temperatures are warm, mice are very active and will breed and expand their population outdoors. Mice have low cold tolerances, so when temperatures get colder in the fall and early winter months, they'll look for warmer shelter and reliable food sources to survive.
Mice are generally wary of humans and prefer to avoid direct contact. However, they may explore the sleeping area if they perceive a food source nearby. To prevent this, ensure your bedroom is free of food remnants, and take steps to seal entry points. If needed, consider using traps as a proactive measure.
Amish communities get rid of mice using a mix of traditional, low-tech, and natural methods, focusing heavily on prevention (sealing entry points, removing food sources) and humane trapping, often with handmade cage traps, while also using strong scents like peppermint oil or cayenne pepper as repellents, sometimes alongside cats for natural pest control. They avoid modern poisons to maintain their lifestyle and focus on practical, sustainable solutions.
To get rid of mice fast, combine immediate trapping with long-term prevention by sealing entry points (using steel wool/mesh), eliminating food sources (cleanliness, sealed containers), and using deterrents like peppermint oil or cayenne near trails; snap traps with peanut butter are effective, but for severe infestations, professional pest control is best.
Surfaces such as glass, glazed wood, polished metal, and plastic don't provide imperfections for their feet to latch onto, making them nearly impossible for mice to scale. For example, the interior of a plastic bucket effectively traps mice because they can't climb the slick surface.
Where to Look
Peppermint oil: Mice dislike the strong scent of peppermint. Soak cotton balls with peppermint oil and place them around entry points or nesting areas. Cayenne pepper or garlic spray: Mix cayenne pepper or garlic with water and spray it along fences, garden borders, and sheds to repel mice.
Mice that are aggressive with humans are jumpy, difficult to catch, overly active, and may even bite their handlers. In interactions with each other, aggressive mice will fight, wound, and even kill each other.
The best way to get rid of mice in your house is to use snap traps. They are inexpensive and very effective. Snap traps come in a variety of different forms, but they all basically do the same thing; they quickly and humanely kill mice.
However, one mouse will almost always lead to an infestation if control methods are not put in place. One pregnant female mouse can produce as many as 10 litters in one year, so it's easy to see that one mouse will soon become many mice unless an effective Integrated Pest Management (IPM) is put in place.
Grapes, raisins, rhubarb and walnuts are poisonous to mice and lettuce can cause them to have diarrhoea. Wild mice find food by foraging and so a portion of daily food that is provided for pet mice should be scattered in a cage to encourage this foraging behaviour.
