Pest control is an underrated benefit of incorporating vegetation into home and office design. Aromatic plants are nature’s solution to bug problems. Their scents are sweet-smelling to humans but offensive to certain insects. They keep pesky unwanted guests at bay without spraying harmful chemicals that contaminate indoor air.
Use greenery to ward off bugs when beautifying your property’s outdoor space and integrating biophilic design into your interiors. Consider these natural insect-repellent plants.
These plants work well in homes because they fit easily in small pots, window boxes, balconies and entryways.
Catnip is one of those plants that keeps mosquitoes away. It contains nepetalactone, a substance found in the herb’s essential oil with bug repellence properties that are as effective as those of DEET, a synthetic compound that disrupts mosquito sensors.
Unlike DEET, which can have potentially adverse health effects, the essential oil produced by catnip is safe. Bed bugs, dust mites, stable flies and ticks also can’t stand nepetalactone.
Citronella has aromatic leaves and essential oils with a citrus scent that help discourage insects. Although the herb has earned the name “mosquito plant,” experts note that the live plant contains only trace amounts of citronellal, the substance that repels these winged pathogen carriers.
For best results, grow citronella in the yard alongside other plants that keep mosquitoes away. Alternatively, crush its leaves to release the oil and create a stronger smell pest can tolerate.
Lemongrass has high citronellal content. This natural pest repellent is more useful when planted in large clumps, so use it whenever possible.
Many growers use lemongrass as patio perimeter vegetation. The plant is suitable for large outdoor containers and can serve as a background for tropical-themed flower beds.
This plant gives off a menthol scent that can help keep mosquitoes, ants and flies away. Since it spreads quickly, you should cultivate it in containers.
It can grow outdoors and indoors. If you want a fresh supply of fresh mint, place pots in areas that receive bright sunlight.
The ideal natural insect-repellent plants for workplaces are low-maintenance, compact and suitable for desks, kitchens, conference rooms or reception areas.
Alliums, including ornamental onions and garlic relatives, release sulfur compounds that insects can’t tolerate. They work best in landscaping outside office buildings rather than indoors.
Lemon balm is a source of citronellal, which gives it a scent similar to citronella. It can help repel mosquitoes, though you should keep it in pots to contain it as it grows quickly.
Peppermint works well in office kitchens or break rooms. Its scent can help discourage flies and mosquitoes while making the room smell fresher.
The snake plant may repel common bugs with its natural pesticide, saponin. Though they’re not known for strong-smelling oils, they’re forgiving and improve indoor air quality.
However, snake plants aren’t pet-friendly. They can be toxic to animals, so avoid growing them around the workplace when it’s typical for employees to bring pawed companions to work.
These plants can repel insects in both residential and work environments.
Basil thrives in kitchens and sunny windowsills. Its oils help deter mosquitoes, flies and gnats. Crushing the leaves intensifies the scent. It’s attractive and easy to grow.
Lavender has a strong floral scent that’s pleasant to people but not to mosquitoes, moths and flies. Place it near windows, doorways, reception desks and patios to create a calmer and more pleasant home or office atmosphere.
Marigolds contain pyrethrum, a common ingredient in insect sprays. Aphids, whiteflies and mosquitoes stay away from these plants. Grow them near doors, windows, terraces or outdoor seating areas to discourage annoying insects from gathering.
Rosemary’s woody scent can discourage mosquitoes and gnats. This plant is compact, drought-tolerant and easy to keep in bright office spaces. It flourishes in pots and looks perfect near outdoor seating areas or kitchen windows.
Not every plant is effective as a natural pest repellent in every house or office. Be selective about which highly scented herbs to grow and what it takes to keep them alive, to keep bugs out and avoid unintended consequences. Here are the primary factors to keep in mind:
Growing highly scented herbs around the house or workplace is key to keeping the environment fresh and bug-free. Put considerable thought into this endeavor to achieve your goals and avoid pitfalls that can put your beloved pets out of harm’s way.
