There are several scents and methods that can be used to repel squirrels. Here are some of the most effective ones:

• Peppermint oil: Squirrels hate the refreshing smell of peppermint oil, so it can be used to deter them. Simply spray peppermint oil around the areas where squirrels are present.

• Apple cider vinegar: The pungent smell of pure apple cider vinegar can repel squirrels. Spray it directly on the areas where squirrels are present.

• Jalapeño pepper: The spicy taste of jalapeño pepper irritates squirrels. When mixed with vinegar, it produces a pungent smell that is disliked by them. Make a spray solution by mixing jalapeño pepper and vinegar and spray it in the areas where squirrels are present.

• Safflower seeds: If squirrels are destroying bird feeders, consider mixing the seeds with some safflower seeds. The bitter taste of the seed will not bother the birds but will keep the squirrels away in a natural way.

• Ultrasonic repellers: These devices create an ultrasonic wave that is not audible to the human ear but can highly irritate the squirrels, deterring them from your house.

• Predators: Squirrels are scared of their natural predators, such as foxes, dogs, and cats. Encouraging these animals to frequent your yard can help keep squirrels away.

• Clean up food sources: Regularly clean up any spilled bird seed or other food that could attract squirrels.

• Barriers: Install metal mesh or plastic netting around the trunks of trees to prevent squirrels from climbing them.

• Repellent sprays: There are specific repellents on the market that can be purchased to help keep squirrels and other wildlife away. These are humane methods to deter squirrels because they do not like the taste or smell of the repellent and will stay away from the area.

Its important to note that some of these methods may work better than others depending on the situation. A combination of different methods may be necessary to effectively repel squirrels.
