Keep Spiders Away Naturally: 5 Chemical-Free Spider Repellents

So, you spotted a spider crawling across the ceiling while you were brushing your teeth—and now you're Googling "natural spider repellents" with one eye on the corner of the room. Don’t worry, you're not alone. Most of us would rather not share our homes with unexpected eight-legged guests, especially the kind that seem to appear out of nowhere like budget horror movie villains.

But before you call in the chemical cavalry, consider this: you don’t need industrial-strength bug spray to keep spiders away. In fact, you probably already have some of the best natural spider repellents sitting in your pantry or bathroom cabinet.

Here’s your full DIY guide to keeping spiders out, naturally—no toxins, no creepy crawlies, and no science-lab smells.

Why Natural Spider Repellents Work (and Why You Should Use Them)

Let’s be real—spiders aren’t evil. They eat other pests, they avoid humans, and they rarely bite unless provoked. But just because they have good intentions doesn’t mean you want them doing yoga in your bathtub at 2 a.m.

Why go natural?

• Safe for pets and kids.

• Better-smelling than commercial bug sprays.

• No residue or chemical fog.

• Eco-friendly (and Instagram-friendly if you’re into that).

So if you’re ready to send spiders packing—gently, naturally, and effectively—let’s dive in.

1. Peppermint Oil: The OG of Natural Spider Repellents

Spiders hate peppermint the way cats hate vacuums. Its intense aroma overwhelms their senses, making it hard for them to hunt or navigate.

How to use peppermint oil:

• Mix 10–15 drops of peppermint essential oil with water in a spray bottle.

• Add a few drops of dish soap or white vinegar to help it stick.

• Spray along windows, door frames, baseboards, inside closets, under sinks—basically anywhere you'd expect a spider rave.

Bonus tip: Soak cotton balls in peppermint oil and tuck them into drawers or corners. Reapply weekly for best results.

2. White Vinegar: Sour Power That Spiders Can't Stand

White vinegar contains acetic acid, which is harmless to us (besides the smell) but extremely unpleasant to spiders. It interferes with their ability to detect chemical signals—like trying to find your way home in a fog with a clothespin on your nose.

How to use it:

• Mix equal parts white vinegar and water.

• Spray liberally in corners, under furniture, behind toilets, and anywhere else spiders like to chill.

• Repeat every 2–3 days, especially after rain or cleaning.

Smell too strong? Add a few drops of lemon or lavender oil to soften the scent.

3. Citrus Peels: A Zesty Way to Repel Spiders

Spiders hate citrus the way toddlers hate nap time. Lemon, lime, orange, grapefruit—any of them can work.

How to use citrus as a spider repellent:

• Rub fresh peels along window sills, baseboards, and door frames.

• Simmer peels in water, let cool, and pour into a spray bottle.

• For bonus points, add cloves or cinnamon sticks to the simmer for a multipurpose aromatic spray.

Quick Myth Buster: Citrus doesn’t kill spiders. It just makes your home smell like summer and tells spiders they’re not welcome.

4. Diatomaceous Earth (DE): The Dust of Doom

This powdery substance is made from fossilized algae. It looks innocent but acts like microscopic razor blades to bugs. It’s one of the few natural spider repellents that can actually kill if spiders crawl through it.

How to apply:

• Lightly dust dry areas—around baseboards, under beds, in closets.

• Avoid using it on wet surfaces.

• Vacuum and reapply every 1–2 weeks.

Warning: Use food-grade DE only. Pool-grade is not safe for indoor use.

5. Cedar: Nature's Built-In Pest Repellent

Cedar has a long history in pest control. Not only does it smell great (like a cozy mountain cabin), but its natural oils repel spiders, moths, and even cockroaches.

How to use cedar against spiders:

• Place cedar blocks in closets, drawers, and under beds.

• Use cedar mulch around the home’s perimeter.

• Add a few drops of cedar essential oil to your DIY spider sprays.

Extra bonus: Your closet will smell like a lumberjack’s aftershave.

6. Lavender, Eucalyptus, and Tea Tree Oil (The Spa Trio)

If peppermint isn't your thing, these oils are also on the spider hit list. They smell soothing to humans, but spiders? Nope.

How to use:

• Mix with water and dish soap in a spray bottle.

• Spray entry points and corners.

• Refresh every few days.

Pro tip: Rotate oils weekly to keep spiders on their toes (or legs… all eight of them).

7. Chestnuts and Horse Chestnuts: Grandma’s Trick

There’s an old tale that placing chestnuts on windowsills keeps spiders away. Science hasn’t confirmed this 100%, but anecdotally—many swear by it.

Try this:

• Place a few raw horse chestnuts around the house, especially on window sills.

• Replace them when they start to mold or shrivel.

Worst case? You get a rustic fall aesthetic for free.

Preventive Spider-Proofing Checklist 🧹

Use these natural spider repellents in combo with daily prevention and your home becomes a no-spider zone:

✅ Close gaps in windows, baseboards, and around plumbing.
✅ Turn off outdoor lights at night (less bugs = less spider snacks).
✅ Declutter storage areas—spiders love untouched boxes and dusty corners.
✅ Vacuum webs and egg sacs ASAP (those babies hatch fast).
✅ Store food in sealed containers—even for pets.
✅ Keep plants trimmed and away from the house walls.

You can do this in 10 minutes a day. Think of it as spider cardio.

Mini Story: When a Spider Moved Into the Toothbrush Cup

One morning, I reached for my toothbrush half-asleep. Something tickled my hand—and yep, there he was. A fat brown spider living rent-free in my toothbrush holder. That was the day peppermint oil spray became part of my bedtime ritual. Don’t wait until you meet your roommate in the bathroom. Be proactive.

Fun Fact: Why Spiders Wander Inside

Ever wonder why they suddenly show up in fall or spring? Turns out:

• In fall, they’re looking for warmth.

• In spring, they’re looking for love (gross).

So those aren't random spider visits. They’re dates. In your living room. No thanks.

Quick Myth Buster: Do Conkers (Horse Chestnuts) Really Work?

Well… maybe. While there’s no conclusive science, many people say spiders avoid them. Worst case scenario? Your house smells nice and looks rustic. So why not?

Bonus Tip: DIY Spider Repellent Sachets

Want a non-spray option?

Make little cloth sachets filled with:
