Our Top 12 Powerhouse Plants That Repel Bugs and Mosquitoes

Ready to build your botanical army? Here is our go-to list of hardworking plants that are as beautiful as they are effective. We’ve included a mix of herbs, flowers, and grasses to give you plenty of options for your garden beds, containers, and window boxes.

1. Lavender (Lavandula)

We humans love the calming scent of lavender, but mosquitoes, flies, and moths can’t stand it. The essential oils in its flowers are a potent natural repellent. Plant it in sunny spots where you like to relax.

Pro Tip: Plant lavender along walkways or near doorways. As you brush past it, you’ll release its fragrant, pest-repelling oils into the air.

2. Marigolds (Tagetes)

These cheerful, easy-to-grow annuals are a classic in the vegetable garden for a reason. They contain a compound called pyrethrum, which is used in many commercial insect repellents. They deter mosquitoes, nematodes, and even rabbits!

Don’t worry—these flowers are perfect for beginners! They thrive on sunshine and are quite drought-tolerant once established.

3. Citronella Grass (Cymbopogon nardus)

This is the famous plant whose oil is the star ingredient in most natural mosquito-repellent candles and sprays. The plant itself carries that distinct lemony scent. For it to be most effective, you need to plant it close to your seating areas.

Important Note: Be sure you’re getting true Citronella Grass, not the “citronella plant,” which is a scented geranium and less effective.

4. Catnip (Nepeta cataria)

While it might drive your feline friends wild with joy, catnip is a serious deterrent for mosquitoes. Studies have shown that its essential oil, nepetalactone, is even more effective than DEET at repelling them. It’s a member of the mint family, so be sure to plant it in a pot to control its spread.

5. Rosemary (Salvia rosmarinus)

This woody herb’s pungent scent is fantastic in the kitchen and fantastic at keeping mosquitoes, cabbage moths, and carrot flies away. It does best in hot, dry conditions and is perfect for containers on a sunny patio.

A little trick I’ve learned: Toss a few sprigs of rosemary onto your grill’s hot coals. The aromatic smoke is a wonderful insect repellent for your barbecue area.

6. Basil (Ocimum basilicum)

Basil is another culinary hero that pulls double duty. Its strong aroma is offensive to mosquitoes and houseflies. Keep a pot of basil by your back door or on your kitchen windowsill to keep flies from venturing inside. There are many varieties, and all seem to have repellent qualities.

7. Scented Geraniums (Pelargonium)

Specifically, the lemon-scented varieties (like Pelargonium crispum) are popular for their mosquito-repelling properties. They have a lovely, strong fragrance that is released when the leaves are brushed or crushed. They look beautiful spilling out of hanging baskets and containers.

8. Mint (Mentha)

Mint is incredibly easy to grow—almost too easy! Its aggressive spreading nature makes it essential to plant in containers. However, that vigorous growth means you’ll have plenty of this aromatic mosquito repellent. It also helps deter ants and mice.

9. Alliums (Allium giganteum)

These “ornamental onions” are stunning. Their tall, slender stalks and large, globe-like purple flowers make a dramatic statement in any garden. As members of the onion family, they emit a scent that repels a wide range of pests, including slugs, aphids, and carrot flies.

10. Lemon Balm (Melissa officinalis)

A cousin to mint, Lemon Balm has a wonderful lemony scent and high levels of a compound called citronellal. It’s a hardy, fast-spreading plant, so like mint, it’s best grown in a pot. Crush the leaves and rub them on your skin for a quick, natural repellent (always do a patch test first!).

11. Petunias

These popular, colorful annuals are sometimes called “nature’s pesticide.” They can help repel aphids, tomato hornworms, and squash bugs. They are easy to care for and come in a rainbow of colors, making them a perfect addition to hanging baskets and container gardens near your vegetable patch.

12. Chrysanthemums (Chrysanthemum)

Mums are another beautiful flower with a secret weapon: pyrethrins. This natural compound is toxic to many insects, including mosquitoes, roaches, and ants. It’s so effective that it’s a key ingredient in many indoor and pet-safe insect sprays.

How to Strategically Place Your Pest-Repelling Plants: Best Practices

Simply having these plants isn’t enough; knowing how to plant that repel bugs and mosquitoes effectively involves strategic placement. Think of it as creating zones of protection. This is where you can apply some helpful plants that repel bugs and mosquitoes best practices.

  1. Guard Your Entrances: Place pots of rosemary, basil, or lavender near doorways and open windows to discourage pests from coming inside.
  2. Surround Your Seating Areas: This is the most important tip! Cluster containers of citronella grass, marigolds, and scented geraniums around your patio, deck, or any outdoor seating area. The closer they are, the more effective they’ll be.
  3. Incorporate into Your Landscape: Plant lavender and rosemary along walkways. When you walk by and brush against them, they release their scent. Use marigolds and alliums as border plants around your vegetable garden to protect your crops.
  4. Create “Scent Pockets”: Group several different repellent plants together in a large container or a dedicated garden bed. This creates a concentrated pocket of scents that pests will be sure to avoid.
  5. Remember to “Activate” Them: The repellent properties come from the essential oils in the plants’ leaves. For an extra boost of protection, gently rustle or crush a few leaves as you sit nearby to release a fresh wave of fragrance.

A Simple Care Guide for Your Bug-Repelling Garden

The good news is that most of these hardworking plants are surprisingly low-maintenance. Following this simple plants that repel bugs and mosquitoes care guide will ensure they stay healthy and effective all season long.

  • Sunlight is Key: Almost all of the plants on our list thrive in full sun (at least 6-8 hours of direct sunlight per day). The sun helps them produce the potent essential oils that make them so effective.
  • Don’t Overwater: Many of these plants, especially woody herbs like lavender and rosemary, are drought-tolerant and hate having “wet feet.” Water them deeply but infrequently, allowing the soil to dry out between waterings.
  • Good Drainage is a Must: If you’re planting in containers, make sure they have excellent drainage holes. For garden beds, amend heavy clay soil with compost to improve its structure.
  • Pruning for Health: Regularly pinching back herbs like basil and mint encourages bushier growth, giving you more leaves (and more repellent power!). Prune lavender and rosemary after they bloom to maintain their shape.

Common Problems with Plants That Repel Bugs and Mosquitoes (and How to Solve Them)

While these plants are fantastic, it’s important to have realistic expectations. Here are a few common problems with plants that repel bugs and mosquitoes and how to troubleshoot them.

Problem: “I planted them, but I’m still getting bitten!”
Solution: Remember, these plants are repellents, not an invisible force field. Their effective range is relatively small. Make sure you have enough plants and that they are placed very close to where you are sitting. On very buggy nights, you may still need a fan or a backup repellent.

Problem: “My mint/catnip/lemon balm is taking over my garden!”
Solution: This is a classic rookie mistake, but an easy one to fix! These plants have aggressive roots that spread quickly. Always plant them in containers to keep them contained. If they’ve already escaped, you’ll need to be diligent about digging them out.

Problem: “My plants don’t smell very strong.”
Solution: A lack of strong fragrance usually points to a lack of sunlight. Scented plants produce the most potent oils when they receive at least 6 hours of direct sun. Move your containers to a sunnier spot if possible.

No single solution is 100% effective. These plants significantly reduce the number of bugs in their immediate vicinity, creating a much more pleasant environment.
