Known List of Smells That Can Help Keep Pests Away

Many pest deterrents are derived from natural ingredients found in many of our backyards. Though many of these are not as effective as manufactured pest deterrents, they can still do the job temporarily on a small scale before a more effective solution is sought out, so keep this in mind should you use any of these smelly ingredients to keep away pests.

Peppermint Oil

Peppermint oil holds a prominent place due to its potent aroma that effectively deters a variety of pests. The myriad benefits of peppermint oil extend beyond its refreshing scent with properties including being antifungal, antiviral, and antibacterial, all which attribute to being a pungent and discomforting presence for insects and smaller rodents. Likewise, this makes it multifunctional in deterring pests and promoting an overall healthier environment, a win-win!

Peppermint oil uses are diverse. It is an integral ingredient in many DIY peppermint remedies for pest control. A popular solution involves mixing a few drops of the oil with water and spraying it around entry points to the house to discourage pests from entering. This is particularly effective against spiders, mice, and ants due to the strong scent that disrupts their olfactory senses.

Notably, peppermint oil for pests offers a safe, chemical-free alternative to traditional, potentially harmful pesticides. Its non-toxic nature ensures the safety of household members and pets. The properties of peppermint oil, coupled with its easy accessibility and affordability, make it an excellent choice for those seeking natural pest control solutions.


Moving on from peppermint oil, another effective natural deterrent for pests is Citronella. Extracted from the leaves and stems of different species of Cymbopogon (Lemongrass), Citronella is known for its potent and distinctive scent which is highly effective in repelling various types of pests, particularly mosquitoes.

Among its many benefits, its use as a mosquito repellent is the most prominent as most know. Citronella mosquito repellent works by masking the scents that mosquitoes and other pests are attracted to, making it difficult for them to locate their targets. Apart from its utility in repelling pests, Citronella also possesses antimicrobial properties that can help combat infections and boost the immune system.

Citronella candles and Citronella essential oil are popular choices for outdoor and indoor pest control, respectively. The candles, when lit, release the Citronella scent into the surroundings, creating a protective shield against pests. Similarly, the essential oil, when diffused, can keep the indoor environment pest-free.

Citronella plants, on the other hand, can be grown in gardens or pots around the house to keep pests at bay, though there is heavy debate over this as it’s the oils that are what’s most effective, rather than the plants themselves.


Known for its soothing aroma and vibrant purple flowers, Lavender also serves as a potent deterrent for a variety of pests. Lavender’s benefits extend beyond its aesthetic appeal and calming scent, however.

Lavender pest control is effective against a range of pests, including mosquitoes, flies, and moths. The scent of lavender is unappealing to these pests, making it a powerful lavender scent repellent. This is largely due to its essential oil properties, which contain active compounds such as linalool and camphor that are repugnant to many insects.

In addition to being a pest deterrent, lavender has other uses. It is widely used in aromatherapy for its calming effect and is a common ingredient in personal care products, from soaps to perfumes. It is also employed in culinary applications for its unique flavor. Because of the above, it’s recommended to be planted in planting beds near windows or doors if possible.


Eucalyptus, with its distinctive scent and medicinal properties, serves as an effective natural deterrent against a range of pests. The eucalyptus benefits in the realm of pest control are manifold, owing to its potent pest deterrent properties. It’s the unique aroma of eucalyptus that makes it an excellent choice for natural pest control; pests such as mosquitoes, fleas, and ticks are repelled by the strong, minty scent.

Eucalyptus oils extend beyond its refreshing fragrance. This essential oil is a potent insecticide, making it an ideal ingredient in homemade pest repellents. When applied on the skin or diffused in the air, it helps keep insects at bay. Eucalyptus oil can also be used in gardening to deter pests from crops and ornamental plants. Furthermore, it’s a non-toxic alternative to commercial pest control products, making it safe for use around children and pets.


Clove, a pungent spice derived from the flower buds of the clove tree, possesses notable pest-repelling properties, particularly against a wide array of insects. This aromatic spice has been used for centuries as a natural remedy against pests due to its powerful clove scent for pests, which insects find repulsive.

The pest repellent properties of clove are primarily attributed to its eugenol content, a compound that is toxic to many insects. Clove benefits are not limited to its culinary uses; it plays a crucial role in natural pest management strategies. From mosquitos to ants and flies, the strong, distinctive aroma of cloves acts as an effective clove insect deterrent, disrupting their sense of smell and keeping them at bay.

Natural clove remedies for pest control are easy to use and environmentally friendly. One common method is to scatter whole cloves in areas where pests are frequent. Another approach involves creating a spray from clove oil and water, which can be directly applied to affected areas. Whether used alone or in combination with other repellents, clove offers a non-toxic and aromatic solution to pest problems.


Cinnamon, a universally cherished spice, not only enhances the flavor of our dishes but also serves as a formidable deterrent to a variety of pests. The cinnamon benefits extend beyond culinary uses, and its pest repellent properties are increasingly being recognized and utilized.

Cinnamon’s aromatic scent uses are many but one of the most notable is its role in natural pest control. The strong, pungent smell of cinnamon can ward off ants, mosquitoes, and even moths. Ants, in particular, are repelled by this spice due to its overpowering fragrance that interferes with their ability to smell food sources. This is why cinnamon is often recommended as a non-toxic, eco-friendly alternative to chemical insecticides.

In practical applications, cinnamon DIY remedies are quite popular. A simple solution can be prepared by mixing cinnamon oil with water and spraying it in pest-infested areas. Another alternative is to sprinkle ground cinnamon around the house, especially near entry points for ants.


Lemongrass, a tropical plant known for its citrusy scent, is another natural ingredient that has proven effective in deterring various pests. Lemongrass benefits range from culinary to medicinal, but one of its most valued uses lies in pest control. The lemongrass plant emits a strong aroma, which is unpleasant for many insects, thus serving as a natural repellent.

Lemongrass uses extend to the production of essential oils. Lemongrass essential oil has a high concentration of citral, a compound that insects find repulsive. When diffused or sprayed around the home, it can deter a variety of pests like mosquitoes, ants, and fleas, showcasing the lemongrass insect repellent properties.

Lemongrass plant care is relatively straightforward, requiring a sunny spot and well-drained soil, which makes it an accessible option for homeowners looking to incorporate pest-repelling plants into their landscapes.

Tea Tree Oil

Derived from the Melaleuca Alternifolia plant, Tea Tree Oil is another potent natural deterrent for a variety of pests.

Furthermore, tea tree oil is a safer alternative to synthetic pesticides that are harmful to the environment. It’s non-toxic to humans and pets, making it an ideal solution for households.


Moving on from natural oils, vinegar, particularly apple cider vinegar, is another substance with pest-repelling properties. The vinegar benefits in pest control are primarily due to its strong and offensive odor that pests find unbearable.

Vinegar uses range from household cleaning to culinary applications, but its use as a pest deterrent is often overlooked. The acidic nature of vinegar, one of its key properties, is particularly effective in deterring ants, fruit flies, and other small insects. It is believed that the strong smell of vinegar disrupts the scent trails left by these pests, making it difficult for them to navigate.

In terms of vinegar effectiveness, it is worth noting that while it is a potent deterrent, it does not kill pests. Rather, it creates an environment that is unattractive to them, encouraging them to leave. This makes vinegar an excellent choice for those seeking a more humane approach to pest control.

Vinegar applications in pest control are many and varied. It can be used in its pure form, or diluted with water and sprayed around the home. Its low cost and easy availability make it a practical, safe, and eco-friendly option for pest control.

Bay Leaves

Often overlooked, bay leaves offer an aromatic solution to pest problems, with their potent scent serving as an effective natural deterrent. The leaves’ strong fragrance, stemming from compounds like eugenol, provides aromatic protection against various insects and pests.

Coffee Grounds

While bay leaves are an effective natural deterrent for pests, used coffee grounds also serve a similar purpose, offering an aromatic and eco-friendly solution to keep various pests at bay. The brewing benefits of coffee are well-known, but its utility as a pest deterrent is just as significant.

Moreover, the use of Rosemary as a pest deterrent aligns with an increasing desire for natural and environmentally friendly solutions. Its effectiveness, coupled with its non-toxic properties, makes it safe for use around pets and children.


Similarly to Rosemary, Basil is another aromatic herb that serves as a natural deterrent to various pests.

Basil, in particular, has earned its place in natural pest control strategies, deterring unwanted insects while also adding culinary and aesthetic value to the surroundings.

Proper Basil plant care is essential to ensure the health and vitality of the plant, and consequently, its pest repellent efficacy. This requires an environment with plenty of sunlight and well-drained soil. Regular watering and pruning also enhance the plant’s growth and the potency of its aroma.
