Plants That Keep Away Mosquitoes

Spring and Summer are known for the arrival of blooming flowers, fluttering butterflies and sandal weather. Unfortunately, this is also the time of year when mosquitoes make their return. By including a few strategic plants in your garden to keep mosquitoes away, you can enjoy spending more time outside without having to wear mosquito repellent.

Initial Considerations

Keep in mind that mosquito-repelling plants can’t completely eliminate the need for mosquito repellent. What they can do is reduce the number of these pests buzzing around your garden. For the greatest effectiveness, arrange mosquito-repelling plants around your deck or patio so their scent keeps mosquitoes away from the areas you like to spend the most time.

Cadaga Tree

The scent of the cadaga tree, a form of eucalyptus, is unappealing to mosquitoes. Simply by planting one in your yard, you can repel these pests and experience fewer mosquito bites all summer long. Eucalyptus oil can even be used as a natural mosquito repellent.

  • Hardiness: Cadaga trees are native to Australia, so as a result, they only grow in desert and tropical regions found in Zones 10 to 12. Click here for Zone information.
  • Seasonality: This tree’s white flowers, which bloom anywhere between late winter and mid summer, also make for a beautiful addition to your garden.
  • Special care instructions: Plant the tree with care, keeping in mind that it can grow up to 80 feet tall. Cadaga trees do best in full sun and need lots of water.


Also known as lemon grass, citronella can grow up to six feet tall. Have you ever burned citronella candles to repel mosquitoes? These feature oil from the citronella plant, which you can grow in your garden to keep away mosquitoes.

  • Hardiness: Citronella is a perennial when planted in Zones 10 and 11. If you live outside these zones, plant the grass in a large (20-inch) container and move it indoors during winter.
  • Seasonality: The grass stays beautiful year-round. If you bring it inside in the winter, trim the top half off and place it under a grow light or on a sunny windowsill to keep it healthy.
  • Special care instructions: Citronella is an invasive plant and can take over your garden if you’re not careful. As a solution, cut out the bottom of a large plastic floral container, bury it, fill it with dirt, and plant an already-mature citronella plant here to keep the roots growing down, not out.


You may love the scent of lavender, but mosquitoes don’t care for it. This makes it the perfect plant to keep mosquitoes away! Plus, the beautiful purple flowers add a nice touch to your garden.

  • Hardiness: A native of the Mediterranean, lavender does best in dry, sunny, rocky habitats. It can grow in as chilly a climate as Zone 5, though warmer zones produce larger plants.
  • Seasonality: While bloom time depends on the type of lavender you plant, you can typically expect to enjoy those lovely purple blossoms from June to September.
  • Special care instructions: Dampness rather than cold is typically what kills lavender. Plant in a sunny location, leave plenty of space between plants and avoid overwatering to help combat this problem.

These are just a few examples of plants to keep mosquitoes away. Other great suggestions include marigolds, rosemary, mint, lemon verbena and catnip. Give some of these plants a try and see the effect they have on the mosquito population in your back yard.
