CHASE THEM AWAY WITH DIATOMACEOUS EARTH
Diatomaceous earth is a white powder, made from the skeletons of microscopic water-dwelling organisms. These organisms live in rivers, streams, lakes, and other bodies of water. They’re called diatoms.
Because of its high absorbency, combining diatomaceous earth with essential oils is a great way to repel rodents. These critters can’t stand the smell of peppermint or lemon citrus essential oils. Combined with diatomaceous earth, you’ve created a rodent repellent that’s natural and safe for humans.
