Which plants will protect you from mosquitoes

When temperatures and humidity levels rise, our gardens and balconies often become unwelcome hosts to mosquitoes. However, their presence is no longer as harmless as we once thought. According to a recent report by the European Centre for Disease Control and Prevention (ECDC), climate change is creating conditions that favor the growth of mosquito populations, potentially leading to a wider spread of mosquito-borne diseases. Fortunately, certain plants can help keep them at bay.

Plants that repel mosquitoes typically have strong, distinct scents that mosquitoes find unpleasant. By placing these plants near seating areas and entrances, you can reduce mosquito encounters while enjoying the added beauty they bring to your garden. Below are some examples of plants that not only help keep mosquitoes away but also enhance your outdoor space with their natural appeal.

Lavender (Lavandula stoechas, Family Lamiaceae)
Have you ever noticed that insects, apart from bees, tend to avoid lavender? This is due to the plant’s fragrant essential oils, which have been shown to impair a mosquito’s ability to detect scents. Lavender is a must-have for every home, thriving in gardens, balconies, and even rooftops. Besides being hardy and drought-tolerant, lavender is one of the most effective mosquito-repelling plants. Its flowers also protect against other insects, like moths, making it a favorite in closets. This aromatic herb reaches a height of up to one meter, with grey-green lance-shaped leaves and purple flower spikes.

Tip: To maximize its benefits, harvest lavender flowers when they are in full bloom.

Lemongrass (Cymbopogon nardus, Family Poaceae)
Lemongrass is a common ingredient in many commercial mosquito repellents, thanks to its proven effectiveness. It is a low-maintenance plant that thrives in garden beds or window boxes as long as it has plenty of light and well-drained soil. It features narrow leaves and can grow up to one meter tall.

Tip: Crush a few leaves to release their essential oils. Be careful not to confuse lemongrass with citronella geraniums, which are often mistakenly labeled as effective mosquito repellents but are less reliable at deterring tiger mosquitoes.

Tulbaghia violacea, Family Alliaceae
This beautiful ornamental plant, native to Africa, belongs to the same family as garlic and onions, emitting a strong odor that mosquitoes dislike. It features dense, upright foliage and round clusters of purple flowers that bloom from summer through early autumn. Place it in a sunny spot and water well until it is established. Although it grows slowly, it requires minimal maintenance and can reach a height of half a meter within five years.

Rosemary (Rosmarinus officinalis, Family Lamiaceae)
While rosemary’s fragrance is beloved for flavoring food, it is highly disliked by mosquitoes. This evergreen Mediterranean shrub can grow up to two meters tall and is resilient, requiring little water or care. Though its lilac flowers attract bees, mosquitoes steer clear of its woody, aromatic stems.

Tip: Toss a few sprigs of rosemary on the barbecue to naturally repel mosquitoes while adding flavor to your grilling.

Marigold (Tagetes spp., Family Asteraceae)
This vigorous annual plant from Mexico is perfect for brightening your garden and repelling mosquitoes with its strong scent. Marigolds grow quickly, reaching up to 50 cm in height, and bloom all summer long as long as they have plenty of sun and are shielded from strong winds. In high temperatures, you may need to water them twice a day to keep them healthy.

Tip: Regularly deadhead wilted flowers to encourage new blooms.

Sage (Salvia officinalis, Family Lamiaceae)
Sage is a powerful aromatic plant with greyish-green, velvety leaves and striking blue-violet flowers. More than 10 varieties of sage grow in Greece, and the plant is renowned for its antiseptic and healing properties, which have been recognized since ancient times. Sage thrives in well-drained, sandy soil and requires little care.

Tip: Burn a few sprigs of dried sage outdoors to not only repel mosquitoes but also cleanse the energy of the area. For a peaceful night’s sleep, try burning sage flowers before bed.

To effectively control mosquitoes, consider using a combination of citronella candles, body-safe insect repellents with essential oils, and eliminating standing water from your outdoor spaces, as even a small puddle can become a breeding ground for hundreds of mosquito larvae.
