Bees play a critical role in pollination, contributing to the health and productivity of ecosystems and agriculture. However, there are instances where people prefer to keep bees at bay, such as for those with allergies or in areas where the presence of bees might pose a risk. While many flowers attract bees, some plants naturally deter them. This article explores the 10 best flowers to repel bees, providing insights into their characteristics, the science behind their repellent properties, and their optimal growing conditions.
Top 10 Best Flowers to Repel Bees
1. Marigolds (Tagetes spp.)
Characteristics and Appearance
Marigolds are vibrant annual flowers known for their bright orange, yellow, and red blooms. They have a strong, pungent scent that is often described as musky or spicy.
Scientific Basis
The strong odor of marigolds is due to the presence of thiophenes, a type of chemical compound that acts as a natural insect repellent. These compounds can deter various insects, including bees.
Growing Conditions
Marigolds thrive in full sun and well-drained soil. They are easy to grow and can be planted in garden beds, borders, or containers.
2. Geraniums (Pelargonium spp.)
Characteristics and Appearance
Geraniums are popular for their wide range of colors, including red, pink, white, and purple. They have a distinctive, sometimes spicy scent and are known for their rounded clusters of flowers.
Scientific Basis
Geraniums produce a chemical called geraniol, which is known to repel bees and other insects. The strong scent of geraniums can mask the floral scents that attract bees, making them less likely to visit these flowers.
Growing Conditions
Geraniums prefer full sun to partial shade and well-drained soil. They are versatile plants that can be grown in garden beds, hanging baskets, or as houseplants.
3. Wormwood (Artemisia absinthium)
Characteristics and Appearance
Wormwood is a hardy perennial herb with silver-gray foliage and small, yellow-green flowers. It has a strong, bitter scent.
Scientific Basis
The primary compound in wormwood is thujone, which has insect-repellent properties. Bees and other insects find the scent of wormwood unpleasant, which helps keep them away.
Growing Conditions
Wormwood thrives in full sun and well-drained soil. It is drought-tolerant and can be used as a border plant or in herb gardens.

Citronella oil, extracted from the leaves, contains citronellal, citronellol, and geraniol, compounds known to repel insects, including bees.
Growing Conditions
Citronella grass thrives in full sun and well-drained soil. It can be grown in garden beds or large containers.
6. Lavender (Lavandula spp.)
Characteristics and Appearance
Lavender is a fragrant perennial herb with gray-green foliage and spikes of purple, blue, or white flowers. It is widely appreciated for its calming scent.
Scientific Basis
While lavender is known to attract bees when in bloom, its strong scent can also deter bees when planted in certain configurations. The high concentration of essential oils in lavender, particularly linalool, has mild repellent properties.
Growing Conditions
Lavender thrives in full sun and well-drained, sandy soil. It is drought-tolerant and can be used in garden borders, herb gardens, or as ornamental plants.
7. Mint (Mentha spp.)
Characteristics and Appearance
Mint is a fast-growing perennial herb with square stems, aromatic leaves, and small purple or white flowers. Its strong, refreshing scent is characteristic of the plant.
Scientific Basis
Mint contains menthol, a compound that can deter bees and other insects. The strong scent of mint can overwhelm the more subtle floral scents that attract bees.
Growing Conditions
Mint prefers partial shade to full sun and moist, well-drained soil. It is best grown in containers to prevent it from spreading aggressively in the garden.
