Sage is a repellent plant for rodents and is easy to grow. When planted outside in temperate regions, it will grow as a perennial herb and overwinter well. In warmer and colder regions, sage will develop well as an annual plant. You should choose soil with a good drainage for the sage, where sun or light is available most of the day.

Lavender: Protection against rodents and mosquitoes

Lavender is also easy to grow in pots and develops well there. The plant requires warmth, plenty of sun, but it’s drought tolerant and grows without fertilizers. Because of the fast growth, lavender is suitable for creating a repelling barrier not only against mice and rats, but it can also help keep mosquitoes away.

Rats and mice surely do not like the smell of garlic and onion. So, if you have a garden, you should definitely grow these plants. Keep in mind that garlic and onion need well-draining soil, plenty of sun, and grow well, planted early in spring.

Though, if you live in a flat, it’s a good idea to use garlic as a mouse and rat repellent, instead of planting it. Just add a purée of five cloves of garlic into a pint (½ l) of water. Then spray with this home-made solution anywhere in the rooms, where mice or rats appear.

The ultrasonic devices, plugged in to an electrical outlet, drive away rodents with high-pitched sounds that are not heard by humans. They are not always very effective, but with their help the repelling power of plants will be strengthened.

Ultrasonic devices can even double the effect of mint, sage and other herbs against mice and rats! They should not be used outdoors, as in that way you’ll be disturbing the living creatures in the garden. Plug the ultrasonic device into the basement or in the attic outlet of your home to protect against rodents.
