The intense smell disrupts their ability to locate food and shelter. This makes essential oils a powerful, natural repellent. Peppermint oil contains high levels of menthol, which creates a cooling sensation. This disrupts the mouse’s sensory receptors, making it difficult for them to navigate.

Eucalyptus oil has a sharp aroma that interferes with their ability to detect food sources. Clove oil has a pungent smell that rodents find unbearable.
