14 Indoor and Outdoor Plants That Repel Spiders

How Spider-Repellent Plants Work (and What They Don’t Do)

1) Strong scents can make a space feel “wrong” to spiders

Many spiders navigate using sensitive sensory hairs and chemical cues. Strong-smelling plantsespecially aromatic herbscan overwhelm the environment with scents that spiders tend to avoid.It’s less “spiders hate this plant” and more “spiders don’t love surprise perfume parties.”

2) Fewer bugs = fewer spiders

Spiders go where food lives. Plants that repel flies, mosquitoes, gnats, and ants can quietly lower the buffet options near your doors and windows.When the menu gets smaller, spider traffic usually follows.

3) Reality check: plants help most when you use them strategically

A mint pot in the far corner of the yard won’t do much for the spider that’s already redecorated your pantry.These plants work best as part of a simple system: position them near entry points, keep the area tidy, and eliminate the “web-friendly” clutter.

Bottom line: you’re aiming for a home that’s less inviting to spidersnot a home that’s sterile, scent-free, and suspiciously quiet.

The 14 Best Indoor & Outdoor Plants That Repel Spiders

Below are the top spider-deterrent plants that are commonly recommended for homes and gardens in the U.S. Each entry includeswhere it shines (indoors, outdoors, or both), what makes it useful, and how to use it without turning gardening into a second job.

1) Lavender (Lavandula)

Best for: Indoor pots, sunny patios, front entries

Lavender smells like a spa to humansand like an eviction notice to many pests. Its fragrant oils can help discourage spiders and the insects that attract them.Place a pot near a bright window, patio seating, or by a doorway that tends to collect webs.

Care tip: Give it sun and well-draining soil. Water when the top inch of soil feels dry.

2) Peppermint (Mentha × piperita) or Spearmint (Mentha spicata)

Best for: Windowsills, kitchen counters, porch steps (in pots)

Mint is famous for its strong, menthol-forward scent. That intensity is the whole point: it can make spider-prone corners less attractive.Bonus: mint can also discourage some small insects spiders snack on.

Care tip: Grow mint in containersunless you want it to become the new landlord of your garden beds.

3) Basil (Ocimum basilicum)

Best for: Kitchens, sunny windows, patio herb stations

Basil’s aromatic oils are why it’s deliciousand why it’s often suggested as a natural pest deterrent.A pot by the kitchen window does double duty: it’s handy for cooking and may help make the area less spider-friendly.

Care tip: Pinch the top growth to keep it bushy. More leaves = more fragrance.

4) Rosemary (Salvia rosmarinus)

Best for: Sunny entryways, patio planters, indoor bright spots

Rosemary is like lavender’s bold cousinwoodsy, strong, and not subtle. That strong scent can help deter pests and reduce insect activity near doors and windows.It also looks great year-round in many climates.

Care tip: Let the soil dry slightly between waterings; rosemary hates soggy feet.

5) Eucalyptus (Eucalyptus spp.)

Best for: Covered porches, bright indoor rooms, decorative cut stems

Eucalyptus is loaded with a sharp, clean fragrance people love in showers and wreaths. That same scent is commonly used in pest-repellent strategies.If growing a live plant isn’t realistic, even cut eucalyptus in a vase near an entry can add a strong scent note.

Care tip: Bright light is your friend. Rotate the pot so it grows evenly.

6) Citronella Grass / Lemongrass (Cymbopogon spp.)

Best for: Patios, outdoor seating areas, sunny decks

Citronella-type grasses are famous for their citrusy aroma. While they’re better known for mosquito control, the same strong scent principle can help make your patio less appealing to crawling and flying pestsspiders included.

Care tip: Loves heat and sun. In cooler regions, grow it in a pot and bring it in before frost.

7) Lemon Balm (Melissa officinalis)

Best for: Indoor herb pots, porch containers, garden edges (controlled)

Lemon balm smells like sunshine and lemonadefresh, bright, and strong. That citrus-mint fragrance can help discourage pests and may reduce the “insect runway” near your home.

Care tip: Like mint, it can spread outdoors. Containers keep it polite.

8) Sage (Salvia officinalis)

Best for: Entry planters, herb gardens near patios, sunny windows

Sage is intensely aromatic. Many homeowners use it as part of “strong scent” pest deterrence, and it’s a great companion to rosemary and thyme in an outdoor herb cluster near doors.

Care tip: Give it sun and don’t overwater. It thrives on a little neglect.

9) Thyme (Thymus vulgaris or lemon thyme)

Best for: Patio borders, window boxes, ground cover near steps

Thyme releases fragrance when brushed or warmed by sun. In high-traffic areaslike near a threshold or walkwayit can add a subtle “nope” factor for pests.Lemon thyme brings an extra citrus note that many people prefer.

Care tip: Trim lightly to keep it dense and encourage new growth.

10) Bay Laurel (Laurus nobilis)

Best for: Indoor pots, patios, kitchen-adjacent doors

Bay leaves aren’t just for soups you forget you’re simmering. Bay laurel has a distinct herbal aroma and is often mentioned in natural pest deterrence.A potted bay tree near a doorway can bring fragrance and an upscale “Mediterranean courtyard” vibewithout the airfare.

Care tip: Bright light indoors. Let the top layer of soil dry before watering.

11) Catnip (Nepeta cataria)

Best for: Outdoor pots, sunny patios, controlled garden containers

Catnip contains nepetalactonefamous for making cats blissfully weird, and also known for repelling certain insects. Less insect activity can mean fewer spiders stopping by for dinner.If you have cats, consider placing catnip where it won’t become a feline mosh pit.

Care tip: Grow in pots to control spreading and to reposition it near problem zones when needed.

12) Marigolds (Tagetes)

Best for: Garden beds along foundations, porch planters, patio borders

Marigolds are classic companion plants with a pungent scent and a long history in pest-conscious gardens.Even if they don’t “target” spiders directly, they can help lower insect activity near your homeespecially when planted along a walkway or foundation line.

Care tip: Sun-loving and easy. Deadhead spent blooms for nonstop color.

13) Chrysanthemums / Pyrethrum Daisy (Chrysanthemum spp.)

Best for: Outdoor containers near doors, fall foundation plantings

Chrysanthemum relatives are associated with pyrethrinsnatural compounds used in many insect control products.That’s why mums are often brought up in discussions about naturally deterring pests around the home, especially in outdoor entry zones.

Care tip: Treat them like seasonal “security flowers” near entrances. Keep watered, especially in pots.

14) Garlic (Allium sativum)

Best for: Garden borders, raised beds near patios, companion planting

Garlic’s sulfur-rich aroma is strong enough to make vampires reconsider their choices, and it’s commonly used in companion planting to reduce pest pressure.While garlic is more about deterring insects than spiders directly, fewer insects near your home can mean fewer spider visitors.

Care tip: Plant cloves in fall in many regions; harvest when tops yellow and flop.

Quick note on safety: Some plants on this list can irritate or be toxic if pets chew them (especially curious cats and dogs).If your pets snack on greenery, place pots out of reach or choose pet-safer optionsand always check trusted pet safety guidance for specific plants.

Placement Playbook: Where to Put Them for Real Results

Hit the “spider highways” first

Spiders don’t usually parachute into your living room for fun. They wander in through gaps, doors, windows, and garage edges.Put your strongest-scented plants near:

• Front door and back door thresholds (outdoor pots: rosemary, lavender, lemongrass, mums)
• Kitchen and bathroom windows (indoor pots: basil, mint, lemon balm)
• Patio corners and outdoor seating (lavender + lemongrass combo works well)
• Garage entry door (a hardy outdoor container like rosemary or marigolds nearby)

Use containers like “mobile defense units”

One of the smartest moves is to keep key plants in pots. When you notice web-building in a particular corner (hello, porch light),you can reposition your aromatic plants closerno landscaping overhaul required.

Don’t forget airflow and light

A stressed plant won’t smell as vibrant, won’t grow well, and may attract its own issues (like fungus gnats).Place each plant where it can thrive so it can do its “aroma job” consistently.

Easy Plant Pairings for Common “Spider Zones”

The “Front Door Welcome Mat” Combo

Try rosemary + lavender in matching planters. It’s attractive, fragrant, and practical.Add marigolds as a pop of color along the walkway if you have sun.

The “Kitchen Window” Combo

Go with basil + mint. You’ll cook more (or at least feel like you could), and the scent stays strong where small insects often gather.If you’re short on light, basil may struggleswap in bay laurel in a bright spot and keep mint in a sunnier window.

The “Patio Hangout” Combo

Use lemongrass + lavender near seating. You get fragrance, a calmer vibe, and a patio that feels less like an all-you-can-eat insect lounge.For fall, rotate in mums near the door.

The “Garage & Utility Door” Combo

Choose tougher container plants: rosemary + marigolds outdoors, and a mint pot indoors near a window.The goal is to reduce the bug traffic that invites spiders to set up shop in storage clutter.

Extra Non-Plant Moves That Multiply Your Results

If plants are the bouncers, these are the security cameras, door locks, and “please stop leaving snacks out” signs.Combine them with your spider-repellent plants for noticeably better results:

• Reduce insect prey: fix outdoor lighting that attracts bugs (warm-toned bulbs can help), clean up crumbs, and reduce standing water.
• Declutter corners: cardboard, stacked boxes, and rarely-moved items are basically luxury condos for spiders.
• Seal entry points: weatherstripping, door sweeps, and repaired screens matter more than most people expect.
• Remove webs regularly: it disrupts “settled” spider behavior and makes the area less appealing over time.
• Manage moisture: spiders (and their prey) often prefer humid, quiet spacesespecially basements and under-sink zones.

Conclusion

The best strategy for keeping spiders away naturally isn’t one magic plantit’s a simple setup: strong-scented plants near entry points,fewer insects to attract them, and a home that doesn’t offer endless hiding spots.Start with two or three plants you’ll actually enjoy caring for (lavender, rosemary, and mint are crowd favorites), place them where spiders tend to appear,and treat the rest like basic home maintenance. Your reward: a nicer-smelling home and fewer surprise webs in the corners.

Bonus: Real-Life Experiences and Practical Lessons

People who try spider-repellent plants usually report the same pattern: the plants don’t “erase” spiders overnight, but they do change the way spider activity shows upespecially around doors, windows, and patios.Below are common, real-world lessons homeowners often discover after a few weeks of experimenting.

1) The “entry-point effect” is real (and fast)

When someone places a strong-scented herb cluster right at the back doorsay, rosemary and mint in containersmany notice fewer webs forming on the doorframe and nearby corners.The reason is simple: that doorway becomes less insect-friendly and more scent-heavy. It’s not that spiders get a calendar invite saying “do not enter.”It’s that the conditions become less ideal for settling.

2) Patios improve most when plants are paired with small cleanup habits

A lot of spider frustration happens outdoors: porch lights that pull in bugs, furniture that stays still for days, and cozy crevices under planters.Homeowners who pair lavender + lemongrass near seating and then add a quick weekly sweep (especially under chairs and near corners) often see the biggest payoff.The plants help discourage the insect party, and the cleanup prevents spiders from getting comfortable enough to build.

3) “Fragrance strength” matters more than the plant’s reputation

A tiny lavender seedling in low light won’t give off much scent, so it won’t do much for spider deterrence. People tend to get better results with robust, healthy plants that actually smell like something.That’s why herbs are so popular for this: when they’re thriving, the aroma is consistent. A healthy basil plant on a sunny sill often outperforms a struggling “fancy” plant in a dim corner.

4) Containers are the secret weapon

One of the most useful tricks people learn is to treat pots like a “mobile perimeter.” If webs keep appearing near a garage door, they move the rosemary pot there.If the patio corner becomes web-central again, they shift lemongrass closer. This flexibility is why potted plants often work better than planting everything permanently in one bed.

5) Sometimes the biggest win is reducing spider “prey” indoors

Many people start this journey thinking, “I need to repel spiders.” Then they realize their real issue is tiny bugs: gnats, flies, or ants.When they add aromatic plants in key spots and fix the conditions that attract those insectsoverwatering houseplants, leaving fruit out, or letting crumbs lingerthe spider sightings tend to drop as a side effect.It’s the food chain, but make it home décor.

6) Expectations get healthier (and that’s a win)

The most satisfied folks aren’t aiming for “zero spiders forever.” They’re aiming for “fewer spiders in the places I live and relax.”Outdoors, spiders are often helpful. Indoors, a reduction is usually the goalespecially in bedrooms, kitchens, and bathrooms.When plants are used as part of a bigger approach, many homeowners find the results feel natural, low-stress, and easy to maintain.

If you want a simple starting plan that matches what many people report works best: pick lavender (pleasant, versatile),add rosemary (hardy, strong scent), and keep mint in a pot (powerful aroma, flexible placement).Then pair that with sealing obvious gaps and a quick weekly web sweep. It’s not dramatic, but it’s effectiveand it won’t make your home smell like a science experiment.
