Wasps can be a real nuisance in the garden, particularly during the warmer months when they are most active. While chemical repellents can be effective, many people prefer natural methods to keep these stinging insects at bay. One of the best ways to deter wasps is by planting certain types of plants known for their repellent properties. Here’s an in-depth look at the best wasp repellent plants to help you create a more pleasant and safer outdoor environment.

 

1. Mint (Mentha spp.)

Why it works: Mint is renowned for its strong scent, which is unpleasant to wasps and other insects. The aromatic oils in mint leaves act as a natural repellent.

How to use: Plant mint in containers to prevent it from spreading uncontrollably in your garden. Place these containers around outdoor seating areas or entry points to your home.

Additional benefits: Mint can be used in cooking and for making refreshing teas. It also attracts beneficial insects like bees and butterflies.

 

2. Eucalyptus (Eucalyptus spp.)

Why it works: Eucalyptus leaves contain eucalyptol, an essential oil that repels wasps. The strong, menthol-like fragrance is highly effective in keeping these pests away.

How to use: Grow eucalyptus in large pots if you live in colder climates, as they prefer warmer conditions. You can also use eucalyptus oil sprays for added protection.

Additional benefits: Eucalyptus oil has antiseptic properties and is used in various medicinal applications. It also adds a lovely, distinctive scent to your garden.

 

3. Wormwood (Artemisia absinthium)

Why it works: Wormwood produces a pungent aroma that is particularly offensive to wasps and many other insects. The plant contains absinthin, a compound that deters insects.

How to use: Plant wormwood in well-drained soil with plenty of sunlight. It can be placed near patios, decks, or other areas where wasps are a problem.

Additional benefits: Wormwood has historical uses in herbal medicine, although it should be used with caution due to its potent nature.

 

4. Lemongrass (Cymbopogon citratus)

Why it works: Lemongrass contains citronella, a well-known natural insect repellent. Its citrusy scent is unpleasant to wasps.

How to use: Grow lemongrass in pots or garden beds in sunny locations. Crushing the leaves releases more of the citronella oil, enhancing its repellent effect.

Additional benefits: Lemongrass is a popular ingredient in many culinary dishes, especially in Asian cuisine. It also has anti-inflammatory and antimicrobial properties.

 

5. Marigold (Tagetes spp.)

Why it works: Marigolds emit a strong scent that deters many insects, including wasps. The plant contains thiophenes, compounds with insecticidal properties.

How to use: Plant marigolds around the perimeter of your garden or near outdoor seating areas. They thrive in full sun and well-drained soil.

Additional benefits: Marigolds are excellent companion plants, helping to repel pests that attack vegetables and other plants. They also add bright, cheerful colors to your garden.

 

6. Basil (Ocimum basilicum)

Why it works: Basil’s aromatic leaves are offensive to wasps. The essential oils in basil, particularly eugenol, are natural repellents.

How to use: Grow basil in pots or garden beds in sunny locations. Place the plants near windows, doors, or outdoor dining areas to keep wasps at bay.

Additional benefits: Basil is a versatile herb used in numerous culinary dishes. It also has antibacterial properties and can improve the flavor of neighboring plants.

 

7. Pennyroyal (Mentha pulegium)

Why it works: Pennyroyal emits a strong minty scent that repels wasps and other insects. It contains pulegone, a compound with insect-repelling properties.

How to use: Plant pennyroyal in pots or as a ground cover in areas where you want to deter wasps. It prefers partial shade and moist soil.

Additional benefits: Pennyroyal has been used traditionally in herbal medicine. However, it should be used with caution, especially in large amounts, due to its potent nature.

 

8. Thyme (Thymus vulgaris)

Why it works: Thyme contains thymol, a compound with insecticidal properties. Its strong aroma is unappealing to wasps.

How to use: Plant thyme in garden beds or containers in sunny spots. Use fresh or dried thyme to create homemade wasp repellent sprays.

Additional benefits: Thyme is a flavorful herb used in cooking. It also has antiseptic and antifungal properties, making it useful in natural remedies.

 

9. Geranium (Pelargonium spp.)

Why it works: Geraniums, especially those with scented leaves, repel wasps with their potent aroma. They contain citronella and other compounds that deter insects.

How to use: Grow geraniums in pots or garden beds around areas where you spend a lot of time outdoors. They thrive in full sun and well-drained soil.

Additional benefits: Geraniums are low-maintenance and add vibrant colors to your garden. They also have properties that can help in natural skin care.

 

10. Lavender (Lavandula spp.)

Why it works: Lavender’s strong scent, while pleasant to humans, is disliked by wasps. The plant contains linalool, a compound with repellent properties.

How to use: Plant lavender in sunny areas with well-drained soil. Use lavender oil or dried flowers in sachets around outdoor seating areas for added protection.

Additional benefits: Lavender is known for its calming and relaxing properties. It’s also used in aromatherapy, skincare, and culinary applications.
