17 Plants that Repel Mosquitoes in Your Garden
Just like any other living creature, mosquitoes have a natural aversion to certain plants. Some may be obvious to you, but others may take you by surprise.
1. Citronella Plant
When it comes to natural mosquito repellent, it doesn’t get much better than citronella. Citronella essential oil is a common ingredient in mosquito repellents, like sprays and candles.
The Brooklyn Botanic Garden recommends planting this lemon-scented grass to keep mosquitoes out of your yard, and its low-maintenance care makes it a great plant for gardeners of all skill levels.
Opt for the Citronella winterianus or Cybopogon nardus varieties.
Citronella grass thrives in warmer climates when planted in sunny areas. If you live in a cooler climate, consider growing this grass in large planters because it cannot withstand frost.
Citronella emits a strong, pleasant citrus scent, which masks other scents. Mosquitoes won’t hang around your yard if they can’t smell you.
Lemongrass contains citronella oil, which is what repels mosquitoes. This clumping grass also makes for an excellent herb, so you can keep mosquitoes away while adding wonderful flavor to your food.
Lemongrass can grow to be four feet tall and three feet wide, so it can take up quite a bit of space in your garden.
Unfortunately, this plant is only hardy in South Florida, which means most people will need to grow this grass as an annual. With that said, the grass is really only needed for the summer months when mosquitoes are out in full force.
Known for its calming, soothing scent, lavender will do more than keep mosquitoes away – it will keep other pests away, too.
The lavender plant’s strong perfume smell comes from the essential oils in its leaves. Experts say the potent scent masks the mosquito’s sense of smell, so they can’t sniff out your CO2.
Lavender is a:
- Plant that repels mosquitoes

And it can repel other pests and animals, too. Bugs and animals are turned off by the scent, so plant plenty of this pleasant-scented plant around your yard.

Bugs and rodents hate mint, peppermint especially. In concentrated form, peppermint is an excellent insect repellent. Its essential oil has also been shown to kill larvae of many bug species and repel adults.
Mint repels more than just mosquitoes and mice – this is a plant that repels spiders, too.
Many people plant mint around the perimeter of their homes to keep pests away. And while you can do the same, be forewarned that mint spreads very aggressively. Once it’s established in your garden, it can quickly take over and be very difficult to remove.
If you don’t want mint to take over your backyard, consider growing this plant in containers and placing them around your patio or yard. Place mint near other plants to keep them insect-free as well.
Mint’s aromatic properties are found in the leaves, flowers, and stems, so all parts of the plant can repel mosquitoes.
Catnip, also known as catmint, is an incredibly effective mosquito repellent. In fact, a study from Iowa State University found that compared to DEET, catmint was ten times more effective at repelling mosquitoes.
A cousin to the mint plant, catnip is fragrant and contains nepetalactone, a chemical that repels insects. But this same chemical attracts potentially unwanted guests: felines. If you want a plant that keeps cats away, catmint is the not a good choice.
This fragrant plant repels bugs and makes your meals taste delightful. Basil works best as a mosquito repellent when planted in containers. Place the containers near doors and outdoor areas where you relax or entertain to keep these annoying bloodsuckers away.

Rosemary grows well in containers, and prefers hot, dry climates. Any variety will repel mosquitoes. Some varieties can grow to be quite large, and are better suited for planting in landscaped beds.
Rosemary can also be used to make a bug-repellent spray.

- Add a quart of cool water to a half-gallon or larger container.
