What Smells Do House Mice Hate?

There are dozens of ways to get rid of house mice. As well as using traps and ultrasonic deterrent devices, did you know that mice can also be repelled with smells? Yes, it’s true, and in this post we’re going to look at how smell can work as part of a mouse control regime.

The reason why house mice are vulnerable to certain scents is because of their extremely sensitive noses. These rodents may have poor eyesight, but they more than make up for it with their other senses. Their acute sense of smell is mostly used to find food, and also to detect predators. They can smell food from long distances, which is why they can so easily find your kitchen. What this also means, though, is that we can use this super power against them.

Ways to use scent to deter house mice

One way to deter mice in the house is with herbs or essential oils. Because mice have such a developed sense of smell, they find many of these plant-based smells overpowering, causing them to leave the area.


Some of best herbs or aromas for house mice are said to be peppermint, eucalyptus and cedar wood. You may want to purchase is an essential oil diffuser. These are relatively cheap, and can be placed in your kitchen, other affected areas where mice congregate or near the cracks and holes where mice exit. You can also place fresh peppermint herbs wherever food is stored.

One note of caution is if you have pets. Cats and dogs can be adversely affected by some herbs and essential oils, so if you are a pet owner wanting pet safe pest control, this may not be a good method for you. In fact, another great way to defeat mice with smell is simply by getting a cat. Felines have a powerful odour which mice can detect, and their smell helps to repel rodents.

Other ideas that use smell to repel mice

Something else that is said to work is keeping pet mice. Groups of mice do not usually like to interact, and actually go to great lengths to avoid each other.

House mice also hate anything hot. This includes Chilli peppers and cayenne pepper. Chilli peppers can be placed around your cupboards and home, and cayenne pepper sprinkled in these areas.

While some of these methods may work, in most cases they are only marginally effective. The balance between DIY and professional mouse control is a fine line. Feel free to experiment with them, but it’s always better to hire a pest control company before things start getting out of hand.
