Gardening is a rewarding hobby that brings beauty, fresh produce, and a sense of accomplishment. However, one of the biggest challenges gardeners face is dealing with pests. While chemical pesticides can be effective, they often come with environmental and health risks. Fortunately, nature provides its own solutions. Certain plants have natural pest-repellent properties that can help protect your garden without the need for harmful chemicals. In this article, we’ll explore 10 plants that keep pests away and how you can incorporate them into your garden for a healthier, more sustainable approach to pest control.
1. Basil
Basil is not only a versatile culinary herb but also a powerful pest repellent. Its strong aroma deters flies, mosquitoes, and thrips. Planting basil near tomatoes can help protect them from aphids and whiteflies.
- How to Use: Plant basil in pots or directly in the garden near vegetables or seating areas to keep mosquitoes at bay.
- Bonus: Harvest the leaves for fresh pesto or salads!
2. Lavender
Lavender is beloved for its calming scent and beautiful purple flowers, but it’s also a natural pest deterrent. Its fragrance repels moths, fleas, flies, and mosquitoes.
- How to Use: Plant lavender around patios, windows, or garden borders. You can also dry the flowers and place them in closets to keep moths away.
- Bonus: Lavender attracts pollinators like bees and butterflies, benefiting your garden ecosystem.
3. Marigolds
Marigolds are a gardener’s best friend when it comes to pest control. They release a compound called alpha-terthienyl, which repels nematodes, whiteflies, and aphids.
- How to Use: Plant marigolds around vegetable gardens, especially near tomatoes, cucumbers, and beans.
- Bonus: Their bright orange and yellow flowers add a pop of color to your garden.
4. Mint
Mint is a fast-growing herb with a strong scent that pests like ants, mosquitoes, and mice find unpleasant. However, mint can be invasive, so it’s best grown in containers.
- How to Use: Place potted mint near doorways or seating areas to repel mosquitoes. You can also crush the leaves and rub them on your skin for a natural insect repellent.
- Bonus: Use fresh mint leaves to make refreshing teas or cocktails.
5. Rosemary
Rosemary is a fragrant herb that deters a variety of pests, including mosquitoes, carrot flies, and cabbage moths. Its woody scent is pleasant to humans but repulsive to insects.
- How to Use: Plant rosemary near carrots, beans, and cabbage. You can also burn dried rosemary as a natural mosquito repellent.
- Bonus: Rosemary is a versatile herb for cooking, especially in roasted dishes.
6. Chrysanthemums
Chrysanthemums contain a natural insecticide called pyrethrin, which is commonly used in commercial pest control products. They repel roaches, ants, ticks, and fleas.
- How to Use: Plant chrysanthemums around the perimeter of your garden or near entry points to your home.
- Bonus: Their vibrant blooms add beauty to your garden in the fall.
7. Garlic
Garlic is a powerhouse when it comes to repelling pests. Its strong odor deters aphids, Japanese beetles, and even rabbits.
- How to Use: Plant garlic near roses, tomatoes, and fruit trees. You can also make a garlic spray by blending garlic cloves with water and spraying it on plants.
- Bonus: Harvest fresh garlic bulbs for use in your favorite recipes.
8. Lemongrass
Lemongrass contains citronella, a natural oil commonly used in mosquito repellents. Its citrusy scent keeps mosquitoes, flies, and other insects at bay.
- How to Use: Plant lemongrass in pots or garden beds near outdoor seating areas. You can also use the stalks in cooking or to make tea.
- Bonus: Lemongrass adds a tropical touch to your garden.
9. Nasturtiums
Nasturtiums are not only beautiful but also highly effective at repelling pests like aphids, whiteflies, and squash bugs. They act as a trap crop, attracting pests away from other plants.
- How to Use: Plant nasturtiums near cucumbers, tomatoes, and squash. Their vibrant flowers also attract pollinators.
- Bonus: The flowers and leaves are edible, adding a peppery flavor to salads.
10. Catnip
Catnip is well-known for its effect on cats, but it’s also a potent mosquito repellent. Studies have shown that catnip can be even more effective than DEET in repelling mosquitoes.
- How to Use: Plant catnip in pots or garden beds near outdoor living spaces. Be cautious, as it can spread quickly.
- Bonus: Your feline friends will love it!
Tips for Using Pest-Repellent Plants in Your Garden
- Companion Planting: Pair pest-repellent plants with vegetables, fruits, or flowers that are prone to pest infestations. For example, plant basil near tomatoes or marigolds near cucumbers.

- Regular Maintenance: Keep your plants healthy and well-pruned to maximize their pest-repellent properties.
