40 Amazing Mosquito-Repelling Flowers and Plants

When the weather is nice outdoors, the last thing you want is a cloud of mosquitoes swarming your backyard BBQ or evening relaxing in a hammock. Not only are mosquitoes annoying and their bites itchy, but they also carry numerous diseases, making the insects both a health hazard and an annoyance. In this guide, I’ll share 40 of the best mosquito repellent plants, including their unique scientific properties and how to grow them in your garden.  

Best Mosquito Repellent Plants for Your Garden and Patio

Why Repelling Mosquitos is Important

Repelling mosquitos using plants offers an eco-friendly alternative to chemical repellents, reducing potential harm to the environment as well as the associated health risks. 

Some of my favorite mosquito repellent plants, such as citronella, lavender, and marigolds, not only deter mosquitoes but also help to beautify spaces and attract beneficial pollinators. 

Plus, by integrating these plants into gardens, you can reduce the spread of mosquito-borne diseases, enhance outdoor comfort, and promote a safer and more biodiverse environment. 

What’s more, this natural approach to mosquito control can lead to cost savings, decreased pesticide usage, and increased enjoyment of outdoor spaces.

How Effective Are Mosquito Repelling Plants and Flowers? 

Certain plants contain specific essential oils and other chemicals that have been shown to repel mosquitoes. These mosquito-repelling plants can be innovative additions to your garden to help beautify your space and discourage mosquitoes from gathering in your outdoor areas.

I find that the potency of these plants often depends on their variety, proximity to individuals, and the quantity in a given area. 

Additionally, local environmental conditions and other mosquito attractions, like standing water, can influence their effectiveness. 

In my experience, these plants can also be combined with other mosquito control strategies for the best results.

12 Other Methods to Keep Mosquitos at Bay in Your Garden or Patio

In addition to planting mosquito-repelling plants around your yard, you can take additional steps to help keep the mosquitoes away. Some effective methods include:

  1. Keep your yard free from standing water where mosquitoes breed, lay larvae, and hatch. This includes ponds, puddles, stagnant bird baths, kiddie pools, and drip trays beneath your potted plants.
  2. Light a wood-burning fire in a safe, city-limits-approved fire pit or chiminea. The wood smoke will help to deter mosquitoes.
  3. While derived from plants, citronella candles and torches can help provide a scent barrier that can deter mosquitoes.
  4. Introduce fish like goldfish or gambusia to ponds or water features. They feed on mosquito larvae and can naturally reduce the mosquito population.
  5. Use a naturally occurring bacterium (such as Bacillus thuringiensis (Bti)) that kills mosquito larvae when introduced to water sources. 
  6. Consider designing your garden to promote airflow, which mosquitoes dislike, and avoid creating shaded, damp areas where they tend to congregate.
  7. Regularly mow your lawn and trim vegetation. Mosquitoes prefer resting in tall grasses and dense vegetation during the day.
  8. Mosquitoes are weak fliers. Using fans in your outdoor seating areas can prevent them from hovering around.
  9. Certain microorganisms or insects, like nematodes, can be introduced to control mosquito larvae in specific environments.
  10. Although they can be a little hit-and-miss in my experience (as well as impacting beneficial insects), bug zappers can be used as a supplementary mosquito deterrent. 
  11. If you have a particular garden spot you want to enjoy mosquito-free, consider using mosquito nets or screens to enclose the space.
  1. Larvicides are products designed to target mosquito larvae in water sources before they can mature into adults. This needs particular care and attention, so always follow the instructions carefully and consult a professional if in doubt. 

If the situation in your yard is particularly out of hand, it might be best to contact a professional pest removal company to have your yard professionally sprayed.

Enjoy Your Time Outdoors With a Choice of Beautiful Mosquito Repellent Plants

Fresh air and time spent in nature are good for the body, mind, and soul, but pesky mosquitoes often prevent us from enjoying that time spent outside. Plant yourself a garden filled with fragrant, anti-mosquito plants, and keep a few pots of them near the entrances to your home, as well. This will help keep the mosquitoes away while creating a beautifully serene and welcoming outdoor space.
