20 Plants That Repel Mosquitos Naturally for an Insect-Free Garden

Nothing ruins a beautiful summer evening faster than the buzz of mosquitos. While sprays and candles offer temporary relief, nature has a more elegant solution — plants that repel mosquitos. These green defenders not only add charm and fragrance to your home but also act as natural pest control, keeping your spaces calm, bite-free, and beautifully aromatic.

What makes mosquito-repelling plants so special is their ability to deter insects through natural oils like citronella, geraniol, and linalool — all safe for humans and pets. From lush lavender to fresh basil, many common garden plants double as mosquito barriers while enhancing your outdoor aesthetics.

In this guide, you’ll discover 20 mosquito-repelling plants that blend functionality with beauty. Whether you’re decorating a patio, balcony, or full backyard garden, these selections help you build an eco-friendly pest control environment that’s vibrant, fragrant, and sustainable.

Rosemary thrives in sunlight and well-drained soil, making it perfect for patio pots or edging. It’s a staple in herbal mosquito defense that combines beauty, fragrance, and usefulness.

8. Catnip

Surprisingly, catnip contains nepetalactone, a compound proven to be ten times more effective than DEET at repelling mosquitos.
