Mosquitoes can ruin a nice evening outside faster than just about anything – itching, buzzing, swatting, we all know the feeling. Sure, chemical sprays exist, but a lot of us want natural alternatives that feel safer for families, pets, and the planet.
Luckily, some plants have natural oils and compounds that actually keep mosquitoes at bay, so just picking the right greenery can help create a bug-repellent buffer around your patio or backyard.
Growing mosquito-repelling plants isn’t just about pest control either, as many of these plants look great, smell amazing, and some even double as kitchen herbs!
1) Citronella Grass
Citronella grass is probably the poster child for natural mosquito repellents. This tall, clumping grass is packed with citronellal, a natural oil that gives off that strong citrusy smell mosquitoes can’t stand.
Stick citronella grass in your garden or pop it in containers on the patio. It works by masking the scents that usually attract mosquitoes to people.
Crushing the leaves helps release more of those oils, which definitely ups the ante. Just keep it watered and warm, as citronella likes the heat.
2) Lavender
Lavender is a go-to for natural mosquito control outdoors. The plant’s natural oils are off-putting to mosquitoes, so they’re less likely to hang around your garden or patio.
If you want the best results, pick lavender varieties with higher camphor content. For a small area, 3 to 5 plants is usually enough, but if you’ve got a bigger space, try 6 to 12 for more coverage.
Plus, lavender just smells fantastic and adds a nice pop of color – can’t complain about that!
3) Marigolds
Marigolds bring a burst of color and help fend off mosquitoes. These flowers have pyrethrum, a natural insecticide that keeps a bunch of pests, including mosquitoes, at bay.
The scent from marigold blooms is what does the trick. You can use them in garden beds or as companion plants around patios or decks.
4) Catnip
Catnip’s got nepetalactone, an oil that’s surprisingly good at repelling mosquitoes. Some research even says it can outperform DEET in lab tests. It’s part of the mint family and isn’t fussy about where it grows.
Plant catnip near seats or doorways to make a natural mosquito barrier. If you don’t want your cats going wild, its relative catmint works similarly but doesn’t attract felines as much.
5) Rosemary
Rosemary is more than just a kitchen staple! It’s a woody herb with a strong scent that mosquitoes really dislike. Pop it in beds or containers close to where you hang out outside.
Crushing the leaves lets out even more of that aroma. And hey, if you’re grilling, you’ve got fresh rosemary right there.
6) Basil
Basil is a fragrant herb that fends off mosquitoes thanks to oils like citronella, limonene, and estragole. Give it sun and well-drained soil, and it’ll be happy in beds or pots near your favorite outdoor spots.
It’s handy for cooking and for deterring pests. Sweet basil and the more aromatic types are especially good for keeping mosquitoes and other bugs away.
7) Scented Geraniums
Scented geraniums, especially Pelargonium citrosum, give off a citrusy smell that naturally keeps mosquitoes at a distance. The aromatic oils in the leaves make the area less inviting for bugs.
Crush the leaves to get more of the repellent effect. They like full sun and well-drained soil, so they’re easy to grow in pots or beds, plus they add some nice color.
8) Lemon Thyme
Lemon thyme is a low, spreading perennial loaded with citronellal, which is a mosquito-repelling compound. Crush the leaves and you’ll get oils that can repel mosquitoes up to 62 percent as well as DEET (not bad, right?).
It’s a breeze to grow in beds or containers, needs almost no fuss, and looks bright and cheerful with its green leaves.
9) Peppermint
Peppermint packs a punch with its menthol scent, which throws off mosquitoes’ ability to find you. This herb grows fast, maybe a little too fast if you’re not careful, so containers are a smart move near seating or entrances.
You can even use peppermint oil on your skin for extra protection, and the leaves are great in drinks or recipes. Multi-tasking at its best.
10) Garlic
Garlic repels mosquitoes with the compounds it releases from its roots and leaves. Its powerful aroma is a big turnoff for these pests. Plant garlic bulbs around patios or outdoor hangouts for a simple protective barrier.
It needs sun, well-drained soil, and a bit of water, but once it’s established, garlic pretty much takes care of itself in the mosquito department.
11) Chrysanthemums
Chrysanthemums are loaded with pyrethrum, a natural compound that mosquitoes (and other bugs) really don’t like. The scent triggers avoidance in mosquitoes, so they’ll steer clear of these flowers.
Crush a few leaves for more effect, and plant them in sunny, well-drained spots for best results.
12) Eucalyptus
Eucalyptus gives off a strong, almost medicinal scent that mosquitoes can’t tolerate. Lemon eucalyptus oil, in particular, contains PMD (para-menthane-3,8-diol), which is proven to repel mosquitoes.
Grow eucalyptus in the garden or keep potted varieties on the patio. The leaves naturally release protective oils into the air, helping keep bugs away.
13) Mint
Mint plants have a powerful fragrance that’s no friend to mosquitoes. The essential oils from mint varieties, especially peppermint, annoy insects and set up an effective barrier in your yard.
Stick mint in beds or pots near where you sit outside. It grows like crazy, and you can use the leaves in your kitchen, too.
14) Bee Balm
Bee balm is great because it releases its oils into the air all on its own, so no need to crush anything. Its strong scent covers up the usual smells that draw mosquitoes in. The plant’s oils repel bugs but attract pollinators like bees, butterflies, and hummingbirds.
Grow it somewhere sunny with decent drainage. It’s not just practical, it’s pretty too.
15) Lemon Balm
Lemon balm’s packed with citronellal, which is found in a lot of store-bought repellents. Rub or brush the leaves and you’ll get a fresh lemony scent. It works well in pots or beds near your favorite outdoor hangouts.
Once it’s going, lemon balm doesn’t need much. It’s a tough little herb that helps keep mosquitoes away and adds a nice touch of green.
16) Tarragon
Tarragon’s natural oils are not mosquito-friendly, so it’s a smart addition to your garden’s pest control lineup. It likes sun and well-drained soil.
You can crush the leaves or make a spray by steeping them in water. It also repels other pests like ants and aphids, and you can snip some for cooking, too.
17) Rue
Rue is a hardy perennial with a strong, bitter smell mosquitoes avoid. Its blue-green leaves have compounds that keep biting insects at bay.
Give it full sun and well-drained soil. Rue grows to about two or three feet and doesn’t need much care once established.
Just a heads-up: the oils can irritate your skin if you touch the plant in sunlight, so maybe wear gloves.
18) Catmint
Catmint is another perennial that’s tough and naturally repels mosquitoes with its aromatic oils. Nepetalactone is the key compound here, and studies say it’s effective at keeping mosquitoes out of your outdoor spaces.
It’s easy to grow in beds or pots, likes sun or a bit of shade, and adds pretty blue or lavender flowers to your yard.
19) Alliums
Alliums (think garlic, onions, chives) are natural mosquito repellents. When you cut or crush the leaves, they give off a strong, pungent odor that mosquitoes can’t stand.
Plant alliums near entryways, along walkways, or in beds where you spend time. Their tall stems work as decorative borders and pest deterrents at the same time.
20) Curry Leaf Plant
The curry leaf plant gives off aromatic compounds that mosquitoes just don’t seem to like. Stick one in your garden or even a pot on your porch, and you might notice fewer of those pesky insects hanging around.
When you brush past the leaves or crush them, they release more of their scent – almost like a little protective bubble! Plus, if you cook, you’ll love having fresh curry leaves on hand. It thrives in warm spots and appreciates a steady drink of water, but isn’t too fussy otherwise.
