Maintaining a home free from pests such as mice, spiders, and insects is a common concern for many homeowners. While chemical repellents are widely available, there’s a growing interest in natural alternatives that are both effective and environmentally friendly. One such solution is the use of certain plants known for their pest-repelling properties. Incorporating these plants into your home not only adds aesthetic value but also serves as a natural deterrent against unwanted critters.
Mint (Mentha spp.)
Mint is renowned for its strong aroma, which is pleasant to humans but repulsive to many pests. Species like peppermint and spearmint contain high levels of menthol, a compound that irritates the sensory receptors of insects and rodents. Planting mint around your home’s perimeter or placing potted mint plants indoors can help deter pests. Additionally, you can create a simple mint-based spray by mixing 10 drops of mint essential oil with half a liter of water in a spray bottle. Spraying this solution in areas prone to pest activity can enhance its effectiveness.
Lavender (Lavandula angustifolia)
Lavender is not only cherished for its soothing scent and vibrant purple flowers but also for its pest-repelling qualities. The strong fragrance of lavender is known to deter mosquitoes, flies, fleas, and moths. Planting lavender near entryways or placing dried lavender sachets in closets and drawers can help keep these pests at bay. Moreover, lavender oil can be used in diffusers to repel insects while adding a calming ambiance to your home.
Chrysanthemums (Chrysanthemum spp.)
Chrysanthemums, commonly known as mums, contain pyrethrum—a natural insecticide that is toxic to insects like ants, roaches, ticks, lice, fleas, and bedbugs. Planting chrysanthemums around your home can serve as a decorative and functional pest deterrent. The flowers can also be used to make a natural insecticidal spray by drying the blooms and steeping them in hot water. Once cooled and strained, this solution can be sprayed in areas where insect activity is observed.
Eucalyptus (Eucalyptus spp.)
Eucalyptus is known for its distinct scent, which is effective in repelling pests like mosquitoes and flies. Placing fresh eucalyptus branches in your home can act as a natural deterrent. Additionally, eucalyptus essential oil can be diluted with water and used as a spray to repel insects. Some people also hang eucalyptus in their showers; the steam releases the oil’s aroma, providing both a refreshing scent and pest-repelling benefits.
Marigolds (Tagetes spp.)
Marigolds are not only vibrant additions to gardens but also serve as natural pest repellents. They produce a scent that deters mosquitoes, aphids, and even rabbits. Planting marigolds near entrances, windows, or in gardens can help reduce pest invasions. Their roots also release compounds that are known to repel nematodes, protecting other plants in your garden.

Basil (Ocimum basilicum)
Basil emits a strong aroma that repels houseflies and mosquitoes. Keeping potted basil plants near doorways and windows can help prevent these pests from entering your home. Beyond its pest-repelling properties, basil is a versatile herb that can be used in various culinary dishes, making it both a practical and functional addition to your indoor or outdoor spaces.
Rosemary (Rosmarinus officinalis)
Rosemary is an herb that deters mosquitoes and other insects harmful to vegetable plants. Planting rosemary in your garden or keeping potted rosemary indoors can help protect your home and garden from pests. Additionally, burning dried rosemary can act as a natural insect repellent during outdoor gatherings.
Catnip (Nepeta cataria)
Catnip contains nepetalactone, which is a strong insect repellent. Studies have shown that catnip is more effective at repelling mosquitoes than DEET, a common ingredient in synthetic insect repellents. Planting catnip around your home can help keep mosquitoes and other insects at bay. However, if you have cats, be aware that they may be attracted to these plants.
Lemongrass (Cymbopogon citratus)
Lemongrass contains citronella, a natural oil that repels mosquitoes. This tropical plant can be grown in pots in cooler climates and placed around the home to deter pests. The leaves can also be used to make a tea or added to dishes for a lemony flavor, providing both culinary and pest-repelling benefits.
Pennyroyal (Mentha pulegium)
Pennyroyal is a type of mint that has been traditionally used to repel fleas, ants, and mice. However, caution is advised as pennyroyal can be toxic to pets and humans if ingested. It’s best used in areas inaccessible to children and pets.
Tips for Using Pest-Repelling Plants Effectively:
- Strategic Placement: Position these plants near entry points such as doors and windows to maximize their deterrent effects.
- Regular Maintenance: Ensure the plants are healthy and thriving, as stressed plants may not produce as much of the repelling compounds.
- Combine Methods: While these plants can help deter pests, combining them with good sanitation practices and physical barriers will provide more comprehensive protection.
Incorporating these plants into your home and garden can serve as a natural and aesthetically pleasing method to reduce the presence of pests.
