Squirrels and chipmunks may look adorable with their fluffy tails and tiny paws, but when they start treating your garden as their personal buffet, it’s time to draw the line. These little critters have a heightened sense of smell that guides their behavior, including where they forage, dig, and nest. Interestingly, certain scents can send them running for the hills, making them invaluable tools for gardeners and homeowners alike. These smells can help you humanely deter squirrels and chipmunks from invading your space while keeping your yard intact.
Peppermint Oil

Peppermint oil is one of nature’s most potent repellents for squirrels and chipmunks. The sharp, minty aroma overwhelms their sensitive noses, making it an excellent deterrent for gardens and homes. You can soak cotton balls in peppermint oil and place them near entry points, bird feeders, or anywhere these critters frequent. Mix the oil with water in a spray bottle for a broader application and mist it over plants and surfaces. While the smell is pleasant for humans, it’s like a slap in the nose for these furry trespassers, keeping them far away from your property.
Garlic

Garlic has a pungent aroma that humans either love or hate, and squirrels and chipmunks are firmly in the latter camp. The sulfur compounds in garlic create a strong odor that effectively repels these animals. You can crush garlic cloves and scatter them around your garden or create a garlic spray to coat your plants. Mix garlic with chili powder to double the deterrent effect for an extra kick. At the same time, your yard might briefly smell like an Italian restaurant, but the payoff of keeping pesky critters away is worth it.
Cayenne Pepper

Cayenne pepper is a double-edged sword for garden protection. Its fiery heat and strong scent make it an effective deterrent for squirrels and chipmunks without harming them. Sprinkle cayenne pepper powder directly onto the soil, bird feeders, or plants to keep these critters at bay. If you’re worried about rain washing it away, mix it with water and a few drops of dish soap to create a long-lasting spray. Just be cautious not to touch your face after handling cayenne—it’s a lesson both you and the squirrels won’t forget.
Black Pepper

The spicy aroma of black pepper can send squirrels and chipmunks running. Its pungent scent irritates their sensitive noses and can even cause mild discomfort if they get too close. Sprinkle black pepper powder around your garden, flower beds, or patio to create an invisible barrier. You can also mix it with water to create an easy-to-apply spray. While this method is safe and natural, be prepared to reapply frequently, especially in areas exposed to the elements.
Chili Powder

Much like cayenne pepper, chili powder is a spicy deterrent that squirrels and chipmunks loathe. Its intense heat and strong scent overwhelm their senses, keeping them from chewing on plants or digging in your garden. Sprinkle chili powder generously around your yard, or mix it with water to create a spicy spray. While this method is highly effective, don’t be surprised if your garden smells like a spicy kitchen experiment.
Coffee Grounds

Used coffee grounds are an eco-friendly way to keep squirrels and chipmunks out of your garden. The strong, bitter aroma is unappealing to them and can mask the scent of tasty plants or seeds. Scatter coffee grounds around flower beds, vegetable patches, or any area these critters frequent. Not only will it deter unwanted visitors, but it will also enrich your soil with nitrogen, making it a win-win for gardeners.
Citrus Peels

The fresh, zesty scent of citrus peels might be delightful to humans, but it’s a big no for squirrels and chipmunks. Orange, lemon, and lime peels can be scattered around your yard to create a natural barrier. You can also rub the peels on hard surfaces like fences or pots to leave a lingering scent. For added effectiveness, combine citrus peels with essential oils for a double dose of deterrence.
Onions

Onions are a natural and inexpensive way to repel squirrels and chipmunks. Their pungent smell and sulfur compounds irritate these animals’ sensitive noses. Slice onions and scatter them around your garden or near entry points. You can also use onion juice as a spray to cover larger areas. While you might have to reapply frequently, especially after rain, onions are a safe and effective way to keep critters from treating your garden as their buffet.
Peppermint Plants

Peppermint’s refreshing scent might delight humans, but it’s a powerful repellent for squirrels and chipmunks. These critters find the smell overwhelming, making peppermint an excellent natural deterrent. Plant peppermint in pots around your garden, or use peppermint essential oil to create a spray. The oil can also be applied to cotton balls and placed near problem areas. Not only will this method keep pests at bay, but it will also leave your yard smelling fresh and invigorating.
Eucalyptus Oil

The strong, menthol-like scent of eucalyptus oil is overwhelming for squirrels and chipmunks. This powerful aroma irritates their sensitive noses, making them avoid areas where the oil is present. You can soak cotton balls in eucalyptus oil and place them around gardens, bird feeders, or entry points to keep these critters at bay.
Apple Cider Vinegar

The sharp, acidic scent of apple cider vinegar is highly unpleasant to squirrels and chipmunks. Spraying diluted vinegar around plants, garden beds, or areas where they frequent can discourage them from coming back. For an added effect, soaking rags in apple cider vinegar and leaving them in problem areas creates a long-lasting deterrent.
Predator Urine (Fox, Coyote, or Bobcat)

Squirrels and chipmunks are prey animals, and the scent of predator urine signals immediate danger to them. They instinctively flee areas where they detect the presence of a predator. Using commercial predator urine sprays around the perimeter of your yard, near trees, or around nesting areas can keep them from getting too comfortable.
Mustard Powder

The strong, spicy scent of mustard powder is too intense for squirrels and chipmunks to handle. It irritates their nasal passages, making them quickly leave an area where it has been sprinkled. A light dusting of mustard powder around plants, garden beds, or bird feeders can prevent these rodents from returning.
Fennel

Fennel has a distinct licorice-like aroma that many rodents find unappealing. This herb naturally repels squirrels and chipmunks when planted in gardens or used in dried form around entry points. Its strong scent masks other attractive food smells, making it an effective way to discourage them from foraging in certain areas.
Cloves

The pungent and spicy scent of cloves is another natural deterrent for squirrels and chipmunks. Whether in whole form or as an essential oil, cloves create an overpowering smell that rodents dislike. Sprinkling ground cloves around problem areas or placing whole cloves near nesting spots can help keep these critters away.
Bay Leaves

Bay leaves have a slightly bitter, aromatic scent that repels many small rodents, including squirrels and chipmunks. Their natural compounds interfere with the rodents’ sense of smell, making food sources harder to detect. Placing dried bay leaves in gardens, attics, or near outdoor structures can act as a natural repellent.
Cinnamon

The strong, spicy aroma of cinnamon is unpleasant to squirrels and chipmunks, making it an effective natural deterrent. Sprinkling ground cinnamon around garden beds, bird feeders, or along fences can help keep them away. The scent lingers for a while, but for best results, reapply after rain or strong winds.
Marigolds
Shutterstock
The scent of marigolds is known to repel various pests, including squirrels and chipmunks. These rodents dislike the strong, pungent aroma of marigold flowers, making them a great natural deterrent for gardens. Planting marigolds around your home or using marigold essential oil in a spray can help keep them away.
Turmeric

Turmeric has a distinct earthy and slightly spicy aroma that squirrels and chipmunks find unpleasant. Sprinkling turmeric powder around garden beds, trees, or bird feeders can discourage these rodents from lingering. Since turmeric is natural and safe for plants, it’s an excellent choice for organic pest control.
Thyme
Shutterstock
Thyme has a strong, earthy scent that squirrels and chipmunks find overwhelming and unpleasant. This fragrant herb disrupts their ability to sniff out food, making it an effective natural deterrent. Planting thyme in gardens, scattering dried thyme around outdoor spaces, or using thyme essential oil in a repellent spray can help keep these rodents at bay. Plus, as a bonus, it adds a pleasant aroma to your garden while keeping unwanted visitors away!
Rubbing Alcohol

The sharp, chemical-like scent of rubbing alcohol is overpowering for squirrels and chipmunks. Dabbing a bit of rubbing alcohol onto cotton balls and placing them in areas prone to rodent activity can help keep them at bay. Refreshing the cotton balls regularly will maintain the strong scent and effectiveness.
Lemongrass
Shutterstock
Lemongrass has a citrusy, lemon-like scent that squirrels and chipmunks strongly dislike. The natural oils in lemongrass mask food sources and create an unappealing environment for these critters. Planting lemongrass or using lemongrass essential oil in a homemade spray can help keep them away.
Basil
Shutterstock
Basil has a strong, slightly peppery scent that repels squirrels and chipmunks. This herb’s natural compounds interfere with the rodents’ ability to sniff out food, making them avoid areas where it’s planted. Growing basil around your garden or using dried basil in repellent mixtures can serve as an effective deterrent.
Rosemary

Rosemary is another fragrant herb that works wonders as a natural deterrent for squirrels and chipmunks. The strong, woody scent confuses their sense of smell, making your garden less appealing. Plant rosemary around your yard, or use dried sprigs to create sachets that can be placed near problem areas. As a bonus, rosemary is a hardy plant that thrives in many climates, adding both beauty and functionality to your garden while keeping pests away.
Lavender

Lavender may smell soothing to humans, but squirrels and chipmunks find its strong floral aroma overwhelming. Planting lavender around your garden can be a natural repellent, discouraging these critters from nibbling on your plants. You can also use dried lavender sachets or essential oils to protect specific areas. As a bonus, your yard will smell incredible, and you’ll enjoy a natural source of relaxation while keeping pests at bay.
