15 Scents That Drive Squirrels and Chipmunks Nuts!!
This post may contain affiliate links.
Squirrels and chipmunks have undoubtedly been described as cute creatures, but they can become a nuisance to gardeners, homeowners, and bird hobbyists alike. All chipmunks are squirrels, but not all squirrels are chipmunks. Squirrels grow to 16-20 inches and 1.5 pounds, while chipmunks are smaller, about 4 ounces.
Their natural foraging behavior and curiosity can damage gardens, bird feeders, and homes. These rodents are well-known pests in vegetable gardens, digging flower beds, and other outdoor issues. Finding effective ways to keep them at bay without resorting to harmful methods is essential for many people looking to protect their properties.
These methods often leverage ingredients found around the house or in the garden, offering an eco-friendly approach to rodent control. Read on!
Citrus
Squirrels and chipmunks are not fans of citrus scents, as they are known to find them repellent. The strong smell of lemon, orange, and grapefruit oils is particularly unpleasant to them.
The acidity of citrus fruits disrupts these animals’ sensitive olfactory senses, making the area unlivable. Citrus peels or citrus-based sprays effectively deter rodents from their plants.
Squirrels have also been reported to avoid citrus-scented products placed around their nests or feeding areas. Scatter citrus peels or sprinkle concentrated citrus oils around your garden for maximum effectiveness.
Cinnamon
Cinnamon has a strong, warm, spicy fragrance that squirrels and chipmunks do not like. The pungent smell can irritate their noses and interfere with their scent trails.
Use cinnamon essential oil or sprinkle ground cinnamon directly around plants and entry points to repel rodents. While it is generally harmless to humans, the smell overwhelms these animals and often leads them to move elsewhere.
Squirrels and chipmunks link pungent smells, such as that of cinnamon, to danger or discomfort. Using cinnamon in places where rodents are known to frequent can be a natural deterrent without harming the environment.
Vinegar
Vinegar, with its sharp, pungent aroma, is another scent that squirrels and chipmunks find offensive. The acetic acid in vinegar irritates their sensitive nasal passages, making them avoid areas treated with it.
Use a vinegar solution in diluted form around the problem area of squirrels and chipmunks. Vinegar can deter foraging patterns by rodents through an area that smells offensive to them.
Vinegar applied around the entry points, such as window frames or burrows, will successfully ward off these animals. Just beware to use it judiciously, as too much vinegar will kill your plants.
Lavender
While the scent of lavender may be very appealing to humans, squirrels and chipmunks do not want to be around it. Lavender is recognized as a natural repellent because of its strong floral fragrance, particularly in essential oil form.
Its strong odor can overwhelm rodents and prevent them from getting into places. Many gardeners use dried lavender sachets or spray plants with lavender oil to help ward off these critters.
Squirrels especially despise the musky smell of lavender, often avoiding sites where this plant is in abundance. This is one of those scents that can work around or within your home and yard.
Dryer Sheets
Dryer sheets, particularly those with a pungent smell, like lavender or spring fresh, are another smell that squirrels and chipmunks don’t like. These are treated with chemicals that leave a strong smell for many animals.
Placing dryer sheets in areas frequented by squirrels or chipmunks will be able to deter them from the area. At the same time, the effectiveness of dryer sheets may vary from one animal to another, many claim to be very successful in repelling rodents from bird feeders and gardens.
The smell from dryer sheets can be overwhelming, obscuring the natural smells squirrels depend on for survival. While nontoxic to humans, one should ensure the sheets are biodegradable to avoid environmental hazards.
Predator Urine
Predator urine is among the strongest natural repellents for squirrels and chipmunks. The smell of predators such as foxes, coyotes, and bobcats produces an instinctive fear response among these little rodents.
It can make the squirrel or chipmunk believe a predator is present, in which case they would be compelled to change locations. Predator urine-based products are commonly used in gardens and yards to repel rodents.
Apply these products in areas where predators would naturally roam, as this maintains the scent’s relevance to the animals’ survival instincts. Reapply the urine regularly for the best results.
Eucalyptus Oil
Eucalyptus oil is strong and has a menthol-like aroma that squirrels and chipmunks do not like. It interferes with the animals’ ability to detect food and navigate their surroundings, making it difficult for them to stay in the area.
Eucalyptus oil can effectively deter rodents when applied strategically around plants, doorways, and burrows. Many gardeners use a diluted mixture of eucalyptus oil and water to spray on plants or around their homes as a natural repellent.
This oil will repel squirrels, chipmunks, and mosquitoes that generally infest a place. Eco-friendly, it doesn’t harm the animals and doesn’t allow them to wreak havoc either.
Garlic
Garlic has a pungent smell that is nauseating for both humans and animals. Squirrels and chipmunks are no exception, as they prefer avoiding garlic-containing areas.
The pungent smell of garlic disrupts the rodents’ sense of smell and signals that the place is unsafe. Gardeners use garlic sprays or place crushed garlic cloves near their plants to ward off these animals.
Garlic also contains compounds like allicin, which provides an antimicrobial effect that benefits both plants and pests. This natural solution is effortless and can prevent squirrels and chipmunks from raiding gardens and homes.
Cayenne Peppers
Because of its strong and pungent smell, Cayenne pepper has gained popularity as a relatively natural squirrel and chipmunk deterrent. The irritating effect of the heat-causing element in chili peppers and capsaicin affects the rodents’ sensitive noses and gastrointestinal systems.
Spread cayenne pepper around the bases of plants or mix it into their bird seed for a similar purpose. This deters squirrels and chipmunks from certain areas since contacting cayenne pepper irritates rodents.
These are harmless to humans and pets but have been observed to work when unwanted wildlife must be diverted. To keep them in place effectively, they must be reapplied after rain or sprinkler systems.
Coffee Grounds
It gives off a pungent, bitter scent that drives squirrels and chipmunks away. This includes the aroma of either pure coffee grounds or brewed coffee, disturbs the animal’s sensory faculties enough to compel it to locate more welcoming quarters.
Spread used coffee grounds in locations around your garden showing evidence of pests. The caffeine and acidity in coffee are believed to make an uncomfortable environment for these creatures.
The pungent smell of coffee is more than a repellent; it also naturally fertilizes plants. However, coffee grounds should be used sparingly, as they can affect the pH levels in the soil.
Marigold, Daffodil, and Hyacinths
Certain flowers, such as marigolds, daffodils, and hyacinths, have odors that offend squirrels and chipmunks. The oils of the flowers contain compounds repugnant to rodents, making them handy in gardens.
Plant such flowers around the periphery of gardens and areas where squirrels have been a problem. Their strong smell effectively repels rodents and attracts several beneficial insects, thus reinforcing the health of the garden.
These flowers work dually, keeping away chipmunks and squirrels while adding beauty to your yard. This natural approach minimizes maintenance and can be another component of an integrated solution to pest control.
Cedar Mulch
Cedar mulch is known for its repelling properties that affect rodents. The strong, woody aroma of cedar drives squirrels and chipmunks away because it interferes with their olfactory senses and, hence, their ability to navigate.
Cedar mulch has been effective in gardens and around the foundational perimeters of homes as a natural deterrent against unwanted pests. The smell of cedar is also a natural insect repellent, further decreasing the possibility of other pests infesting your outdoor space.
For maximum efficiency, though, the cedar mulch has to be fresh because the odor may wear off after a certain period. This solution against rodents is long-term and completely natural.
Onions
Squirrels and chipmunks do not particularly appreciate the overwhelming, pungent smell of onions. Onion sulfur compounds irritate their sensitive noses, preventing the animals from being around places with onions too often.
Many gardeners make onion-based sprays or place onions and their peels along and within their gardens for a non-aggressive, preventative way to repel rodents. Though not one of the more common odors, onions naturally correct rodent problems inexpensively.
This strong-smelling agent naturally repels other garden unwanted critters, such as rabbits and deer. Onions should be replaced every once in a while so that their power does not diminish over time.
Peppermint Oil
Peppermint oil is another essential oil that squirrels and chipmunks find overwhelmingly unpleasant. The strong menthol scent disrupts the rodents’ ability to detect food and navigate, leading them to seek out less odorous areas.
Some people mix a few drops of peppermint oil with water in a spray bottle and apply it to areas where squirrels are causing trouble. Others dip cotton balls in peppermint oil and place them near entry points or around plants.
This method is nontoxic to humans, pets, and plants yet highly effective at keeping rodents away. For ongoing protection, reapply the peppermint oil every few days.
Pepper
Black pepper and other pepper-based spices are also useful in repelling squirrels and chipmunks. The pungent smell and irritating effects of pepper cause discomfort for these small mammals.
Pepper can disrupt animals’ ability to smell and taste, making the area less inviting. Sprinkling black pepper around plants, bird feeders, or entry points can keep squirrels and chipmunks from raiding your property.
However, be cautious when applying pepper around pets, as it may irritate their eyes or nose. This is particularly useful in areas of high traffic or where other scents may have worn off.
