A neighbor mentioned she'd had the same issue with her barn. Mice in the feed, rats under the floor. She used these small repellent pouches and hadn't seen any rodents since spring.
Honestly, I didn't expect much. It looked like another "natural" product that would work for two days.
But then I read how it works, and it made sense.
Rodents live by their nose. Mice, rats, squirrels, chipmunks. They find food, shelter and nesting spots mostly by smell. If an area smells wrong to them, it feels unsafe, and they move on.
The problem with sprays and cotton balls is that the scent disappears fast. Rodents just wait it out.
These pouches are different. They use a blend of Peppermint Oil, Cinnamon Oil, Castor Oil and Cedarwood Oil instead of just peppermint, in a pouch that releases the scent slowly. One pouch lasts up to 90 days.
So I ordered a pack.
