Try planting basil along your garden’s edge, as it helps protect your veggies, especially tomatoes and peppers, and might even boost their flavor a bit.
Snip basil regularly to keep it growing strong and bushy; you’ll get more leaves for cooking and better bug protection all season.
2) Marigold
Marigolds are well-known for keeping loads of garden pests at bay with their pungent scent. French marigolds are especially handy, as they give off chemicals that send aphids, whiteflies, and other troublemakers elsewhere.
They also secrete a natural toxin into the soil that’s bad news for root-knot nematodes. Scatter marigolds throughout your garden for a bright, protective border that also brings in bees and butterflies.
3) Lavender
Lavender’s lovely scent isn’t just for show, as it actually keeps away mosquitoes, moths, flies, and fleas. The essential oils in the plant do the heavy lifting here.

4) Citronella
Citronella is probably the first thing that comes to mind when you think of natural insect repellents. The real deal is citronella grass (Cymbopogon nardus or Cymbopogon winterianus), which is where that famous citronella oil comes from.
This tall, clumping grass is loaded with citronellal, a compound that bugs hate. Put some citronella around your patio or garden to help cut down on pests in your hangout spots.
5) Mint
Mint’s strong scent, especially the menthol in it, keeps a surprising number of insects away. Peppermint and spearmint are both good options for deterring mosquitoes, flies, ants, aphids, even spiders.
The aroma messes with how insects communicate and find food. Try planting mint in containers near doors or in strategic spots outside for a natural bug shield.
6) Chives
Chives are more than just a garnish, they actually repel pests like aphids, spider mites, Japanese beetles, and carrot flies with their sharp scent.
Stick chives near your veggies and flowers for a little extra protection. Their purple flowers also attract helpful insects that’ll eat some of the bad bugs.
They can grow surprisingly tall and work well as companion plants in most gardens, so you don’t need to spray anything toxic.
7) Rosemary
Rosemary does double duty as a tasty herb and an excellent pest deterrent. Its strong, woody aroma repels mosquitoes, flies, aphids, slugs, snails, and Japanese beetles.
Plant rosemary near your other crops for extra protection. It’s happy in pots too, so you can keep it on a balcony or windowsill if you’re short on space.
8) Garlic
Garlic’s sulfur compounds act as a natural bug repellent. The strong smell confuses insects and helps protect nearby plants.
Try tucking garlic throughout your garden to cut down on aphids, beetles, and spider mites. The smell throws off bugs’ senses, and planting it in rows seems to work better than scattering bulbs at random.
9) Bay Leaf
Bay leaves from the bay laurel plant are naturally aromatic and keep a lot of household pests away. Fresh or dried bay leaves can help deter flies, roaches, and pantry bugs.
Stash bay leaves in spots where pests show up – windowsills, cupboards, pantry corners etc. The oils they release make the area less appealing to insects.
You can even pair bay leaves with cloves or lavender for a little extra punch.
10) Nasturtium
Nasturtiums have a peppery scent and give off airborne chemicals that keep aphids, whiteflies, squash bugs, cucumber beetles, and cabbage loopers away. They’re great near tomatoes, cucumbers, eggplant, and peppers.
They also bring in helpful insects that eat pests, so you get two benefits in one. It’s no wonder they’re popular companion plants for veggies.
11) Chrysanthemum
Chrysanthemums contain pyrethrum, a natural insecticide that repels ants, mosquitoes, fleas, cockroaches, and more. It messes with pests’ nervous systems and is a go-to for organic gardeners.
The pyrethrum daisy (Chrysanthemum cinerariifolium) packs the most punch. Plant these near your veggies or garden beds for protection and a burst of fall color.
12) Lemongrass
Lemongrass is loaded with citronella oil, which keeps mosquitoes, flies, ants, spiders, roaches, and fleas at bay with its citrusy scent.
It’s easy to grow, even for beginners, and the citronellol and geraniol in it make pests think twice before coming near. Place lemongrass near patios or doorways for a living bug barrier.
13) Catnip
Catnip may be loved by cats, but it’s also a serious mosquito repellent and can even rival DEET, according to some studies. Its oils also keep away flies, ants, aphids, and cockroaches.
Plant catnip in a sunny, well-drained spot. It makes a solid companion plant for veggies and fruit, plus it attracts helpful insects to your garden.
14) Thyme
Thyme is a low-growing herb that’s surprisingly good at repelling bugs. Thymol, one of its main compounds, keeps away cabbage worms, whiteflies, corn earworms, and tomato hornworms.
Thyme’s oils also deter mosquitoes, moths, ants, fleas, and ticks. It’s practical in the garden and handy in the kitchen – a win-win!
15) Sage
Sage is another herb that bugs don’t like. It’s full of volatile compounds (terpenes, camphor, phenolic acids) that give it that distinctive smell and keep pests at bay.
It’s good for deterring mosquitoes, snails, cabbage moths, flea beetles, and carrot flies. Try planting it near cabbage, carrots, strawberries, or tomatoes for extra protection.
Sage’s aromatic leaves hide the scent of other plants, making it tougher for pests to find them. Burning dried sage outside is also a classic trick for keeping mosquitoes away.
16) Peppermint
Peppermint is packed with menthol, which messes with the senses of all sorts of bugs, including mosquitoes, flies, spiders, ants, aphids, and some beetles.
Grow peppermint around outdoor hangouts or use peppermint oil as a spray. The scent is strong enough to drive insects off while making your garden smell great.
Peppermint works in most climates and is handy for cooking or even herbal remedies, too.
17) Eucalyptus
Eucalyptus has a strong, unmistakable scent that naturally keeps mosquitoes, flies, roaches, ants, and spiders away. It’s a good choice for planting around the edges of your garden.
The oil from eucalyptus leaves can be mixed with water and vinegar for a DIY insect repellent spray. Just spritz it where bugs like to gather.
18) Fennel
Fennel is a bit of a multitasker: it repels pests with its strong scent and brings in good bugs when it flowers. Those umbrella-shaped blooms attract hoverflies, lacewings, and parasitic wasps.
These helpful insects take care of aphids and other soft-bodied pests for you. Plant fennel near your veggies for natural pest control, and don’t forget, it’s tasty in the kitchen, too!
19) Geranium
Geraniums have a knack for keeping mosquitoes, flies, and beetles at bay, thanks to the distinct compounds in their leaves and flowers. The citronella-scented ones, in particular, seem to do a stellar job with flying pests and, honestly, they brighten up the garden, too.
If you’ve got veggies that always get nibbled or a patio that attracts bugs, try planting geraniums nearby or tucking them into hanging baskets around your seating spots. They really do best in sunny places with soil that doesn’t stay soggy. You’ll find them in pink, red, and white – pick your favorite. Snipping them back now and then not only keeps them looking good but also helps release more of those bug-repelling scents into the air.
20) Tansy
Tansy is a perennial herb with cheerful yellow, button-shaped flowers. It’s known to repel a variety of insects, including ants, fleas, beetles, mosquitoes, thanks to thujone and a mix of other sharp-smelling compounds that bugs just can’t stand.
If you want to grow tansy, give it a sunny spot with well-drained soil. It does double duty: brightening up your garden and helping keep pests at bay. Just a heads up, though, tansy can really take off and spread more than you might expect. You might want to stick it in containers or a spot where you can keep it in check.
