Keep Mice and Rats Away with Coffee Grounds

Use either new or old coffee grounds for this task; they will work just as well. Keep the coffee grounds for use as a pest deterrent if you drink coffee every day. Put the grass in the corners of your basement, garage, and attic, as well as near any possible entrances.
The efficiency of coffee grounds decreases with time, thus it’s important to refresh them often. If you want the powerful aroma to last, you need to change the grounds every week.
Peppermint oil is known to be a rodent deterrent; to make it even more effective, combine it with coffee grinds. This makes it more effective as a deterrent.
Extra Advice
