What Smells Do Mice Hate? | Native Pest Management (2024)

Few people want to share their home with mice of the undomesticated variety, for good reason. According to the Florida Department of Health, mice and other rodents are known to spread up to 35 diseases to humans worldwide.

These include the Lymphocytic Choriomeningitis Virus (LCMV), which spreads to humans through common house mouse droppings, urine, and their bedding. LCMV causes mild symptoms in most people, though pregnant women can pass it along to their fetuses with deadly results.

Key Takeaways

  • Mice are capable of spreading a variety of diseases to humans.

  • Certain smells can deter mice and may be used for prevention.

  • Natural oils and other substances are commonly used as mouse repellents.

Common Smells Mice Dislike

Mice have a strong sense of smell, which they use to avoid danger and find food. Certain odors can repel these pests effectively, making these scents crucial in deterring mice.

Natural Oils and Herbs

Peppermint oil is often hailed as a natural mouse repellent. The strong scent of peppermint is overwhelming to mice. Similarly, essential oils such as eucalyptus oil, bergamot oil, clove oil, and cinnamon oil are potent in keeping mice at bay.

One study noted that eucalyptus oil applied once a day was more effective as a rat repellant than once a week.

Regular tea bags infused with these scents, cinnamon sticks, and dry lavender can also deter mice when placed in areas of mouse activity.

  • Oils: Peppermint, Eucalyptus, Cinnamon

  • Herbs: Clove, Cayenne Pepper, Cinnamon

Household Items and Repellents

Mice avoid the smell of household items like vinegar and ammonia due to their pungent odor. Bleach also acts as a strong deterrent due to its intense smell. Mothballs and dryer sheets, containing naphthalene or essential oils, can repel mice.

However, the concentration of these smells and the frequency of replacement are key to their effectiveness.

Tips for Using Smells to Deter Mice

For natural oils, a diffuser or cotton balls with oils can spread the scent effectively. Replace the scent sources regularly to maintain a high concentration. Position them near entry points and areas with frequent mouse activity.

Risks and Considerations

While these scents can deter mice, they can also cause irritation or severe health effects if misused. Always follow the formulation instructions on commercial mouse repellents and use food-grade items to prevent damage to surfaces or health risks.

Other Strategies for a Mouse-Resistant Home

The Centers for Disease Control and Prevention (CDC) recommend a combination of strategies for creating a mouse-resistant home and cleaning up after rodent infestations. These include:

  • Regularly cleaning the household

  • Removing food sources or storing food in airtight containers

  • Sealing gaps in your home’s exterior and interior with steel wool, caulk, or spray foam

  • Frequently disinfecting surfaces and clothing

  • Setting mouse traps

When faced with a serious rodent infestation, such as those involving mice in heating and cooling ventilation systems, the CDC recommends contacting a qualified pest control professional.
