Do coffee grounds repel chipmunks?
Similarly, you may ask, what smells do chipmunks hate?
Contrary to the noses of humans, chipmunks absolutely can't stand the smells of certain strong oils like peppermint, citrus, cinnamon, and eucalyptus. Additionally, chipmunks can't stand the smell of garlic.
Also asked, how do you keep chipmunks out of your garden?
Bring in a "predator": A decoy predator, like a motion-activated owl, can scare chipmunks away from your yard. You can also buy a spray product made from the urine of predator animals like red foxes and cats. The smell will convince chipmunks that they're in danger - and they'll stay away.
Coffee grounds are highly acidic, they note, so they should be reserved for acid-loving plants like azaleas and blueberries. And if your soil is already high in nitrogen, the extra boost from coffee grounds could stunt the growth of fruits and flowers.
