Using repellant is a good way to get rid of squirrels as well as pests. At garden stores, buy a safe, effective repellant that is specially designed to repel squirrels and small rodents. You can be more creative by making your own all-natural repellants at home. Usually, squirrels do not enjoy the smells of spices, so sprinkle some pepper sand chili powders over the places where they visit.
Spices and natural repellants are less likely to cause harm to the squirrels. The ingredients will not affect the growth of your plants either. Another type of repellant is garlic, which can be mingled with water, vinegar and jalapeno pepper and used as a spray. It is important to use these repellants regularly and make reapplications every time it rains.
Peppermint is another scent that squirrels detest, so placing a peppermint plant in the garden is recommended. You can also dip strong-scented peppermint oil in cottonballs and drop them all over the garden.
Mothballs are natural repellants that are fatal when moths ingest them, but only annoying when squirrels taste them. Place a few of these mothballs all over the garden or stuff them in nylon stockings to hang on the wire fence. The mothballs are not pleasant to taste and keep the squirrels out.
