3 Methods to Squirrel-Proof Your Garden

If you have plants outside or are contemplating buying some, it’s important to be mindful of squirrels and other critters. Squirrels love many of the same plants people do, and while they can be quite entertaining to watch, they can also cause extensive damage. If you’re looking for ways to squirrel-proof your garden, read on for useful tips.

1. Natural Repellents

Squirrels have a keen sense of smell and dislike powerful scents. Natural repellents are a safe but temporary solution to protect plants. The repellents listed below need to be re-applied regularly, especially after a rain.

• One of the most commonly used natural squirrel repellents is cayenne pepper. Sprinkle it directly on plants and on the soil itself. Its spiciness will send squirrels scurrying after just one bite.
• While you may think coffee is delicious, squirrels do not! Spread used coffee grounds around the base of plants to protect them.
• Bone meal has a strong odor, deterring squirrels from damaging plants. It’s also a great fertilizer, so it’s a double win!
• If you have a dog, save their hair next time you groom them and place it on the plant soil. Believe it or not, a dog’s scent will scare away squirrels. There’s no need to add large clumps—a little will do. Just reapply when the scent wears off.
• Several flowers—alliums, crocuses, daffodils, lilies, and hyacinths—have a smell or taste that squirrels simply hate. These plants should be safe from damage and may even protect plants in the vicinity. Plus, they will make your garden more vibrant and beautiful!

2. Physical Barriers

Physical barriers provide a more permanent solution to squirrel-proof your garden. Besides being environmentally friendly, they only require one-time installation, making them a good option for people who are too busy to reapply natural repellents.

• To prevent squirrels from digging, place wire mesh on top of the soil surrounding your plants. Cover the mesh with a shallow layer of soil or mulch so it’s hidden from sight. If your plants are in outdoor containers or garden beds, don’t worry! You can create a cage by attaching wire mesh around the interior perimeter. Note that wire mesh needs to be installed at a depth that squirrels can’t dig under—typically 6 inches.
• Place rocks or pebbles around plants to dissuade squirrels from digging. It also adds a unique touch to your garden and flower pots.

3. Devices

Devices are a great solution that don’t require as much of a commitment as natural repellents and physical barriers—just place them and let them do the work. In order for these tools to be most effective, they need to be placed in strategic locations, so take time to consider your options.

• Humans can not hear the high-pitched noise emitted from ultrasonic repellent devices, but squirrels can, causing them to leave the area immediately. You may need more than one ultrasonic device if you have a large area.
• Motion-activated sprinklers are another great option to deter squirrels. Water is harmless, and by placing the sprinklers in calculated locations, you may not need to water your plants as often.

Sometimes squirrels are stubborn and aren’t discouraged by the above suggestions. In those cases, try a live trap to squirrel-proof your garden. Don’t let squirrels and other outdoor critters keep you from decorating your space with plants. Test out several options to find the best fit for you and your garden, and you won’t have to worry about squirrel damage again!
