When it comes to keeping squirrels away, there are a few scents that seem to work well. One is the scent of peppermint oil, which can be used in a number of ways. For instance, you can add a few drops of peppermint oil to a cotton ball and place it near areas where squirrels like to congregate. You can also make a spray by mixing 1 part peppermint oil with 10 parts water, and spraying it around the perimeter of your property.
Another effective scent for deterring squirrels is vinegar. Vinegar has a strong smell that squirrels seem to dislike, so using it in a similar way as peppermint oil can help keep them away from your property. Simply mix 1 part vinegar with 10 parts water in a spray bottle and apply it around the areas you’d like to protect.
Finally, cayenne pepper also seems to work well as a squirrel repellent. You can mix together equal parts cayenne pepper and flour, and then sprinkle this mixture around areas where squirrels are active. The heat from the cayenne will deter them from coming back!
