How Peppermint Oil Helps Keep Spiders Out of Your Home

A first spider appeared on the bathroom ceiling - stocky and motionless - hovering right above the mirror.

Not even an hour passed before a slimmer one was parked in the hallway corner, exactly where the night light spills its faint orange glow. Same house, same day, and the same quick stomach-drop each time eight legs seemed to materialise.

By evening the windows were shut, the heating was running, and the air carried a light mix of washing powder and toast. Outside, the garden sat wet and black. Inside, it felt as though something was practically rolling out the welcome mat.

A neighbour offered a tip that sounded more like a TikTok trick than something you’d trust in real life: “Just use peppermint oil, they hate it.” She said it while rubbing her hands on her jeans, like it was utterly routine.

The following day, the place smelled like mint sweets - and that’s when the story took a turn.

Why spiders hate that fresh peppermint smell

The first thing peppermint oil does, once you spray it into a room, is flood the air with a clean, sharp freshness. It’s brisk and almost icy - like the first breath you take when you step outside on a cold morning. That same crisp note that feels energising to you can be completely off-putting to spiders.

Spiders “read” your home through their legs and fine hairs, picking up chemical traces in the air and on surfaces. Peppermint doesn’t politely hint that they should leave - it overwhelms them. Wrong place. Wrong smell. Turn back.

So while you’re thinking, “Now my house smells like chewing gum,” the spider is effectively thinking, “This territory is hostile.” Everything looks normal at human scale - skirting boards, window frames, plug sockets - but at a microscopic level you’ve changed the route map.

On a damp October night in Manchester, one family tried it with a half-laugh, not expecting much. Mum grabbed a cheap spray bottle, topped it up with water, added a generous splash of peppermint oil, and misted the living room, hallway and the bedroom door frames. She aimed at the usual culprits: the gap under the front door, the corner beside the shoe rack, the window with the broken seal.

For weeks they’d been dealing with one or two house spiders a day - and not the dainty kind, either. The sort that suddenly bolts across the carpet mid-film. They weren’t logging it in a spreadsheet; it was just that familiar household thought: “Why are there so many this year?”

Over the next three nights, the pattern changed. A stray web showed up near the kitchen window, but the big hallway sprinters? Gone. Every so often she still spotted a tiny one up near the ceiling, but the surge had eased. No harsh chemicals. No sticky traps. Just a home that now carried the faint aroma of a posh candle shop.

There’s a plain, slightly unglamorous reason it can work. Spiders aren’t plotting a takeover to annoy you. They follow food, moisture and undisturbed, shadowy corners - and your house is often a cosy extension of the garden.

Peppermint oil doesn’t kill them. Instead, it disrupts the signals they depend on. The strong smell can mask the trails and cues they use to travel, hunt and hide. Picture trying to track a subtle perfume in a room thick with burning incense - your senses simply stop being useful.

That’s also why a few drops in a diffuser rarely makes a dramatic difference. What matters is how strong the scent is and exactly where it’s placed. You’re not creating a spa atmosphere; you’re putting up an invisible, mint-scented fence.

How to use peppermint oil to keep spiders out – step by step

Keep it straightforward: a small spray bottle, a bottle of pure peppermint essential oil, and ordinary tap water. Fill the bottle almost to the top with water, then add roughly 10–15 drops of peppermint oil for every 250 ml. Shake well until the mixture looks slightly cloudy and the whole bottle smells powerfully minty.

Move slowly through your home and mist along skirting boards, window sills, door frames, and especially those “guilty” corners where webs tend to appear. Don’t drench surfaces - a light spray is enough, just to leave a faint sheen for a minute or two. Prioritise entry points: the gap around the letterbox, vents, cracks, and the thin line where the carpet meets the wall.

At first, do this weekly, then refresh every couple of weeks as the smell fades. Let’s be honest: nobody truly does this every single day.

This is where many people lose patience: they try it once, don’t get instant results, and abandon it. Or they dilute it too much and then wonder why nothing changes. In reality, you’re working against habits - the spiders’ and your own.

If you’ve got pets or small children, take extra care. Keep sprays in low areas light, and avoid soaking fabrics they could chew or lick. You’re aiming for a strong scent, not a slippery floor or irritated skin. Always patch-test first on varnished wood or painted walls; peppermint oil can sometimes leave faint marks if it’s used undiluted.

Another frequent slip-up is forgetting clutter. A peppermint “barrier” along the skirting won’t achieve much if there’s a ready-made spider hotel behind stacked boxes. Pair the mint routine with a quick clear-out, one room at a time - not a deep clean, just moving that “I’ll deal with it later” pile away from the walls.

“Peppermint oil doesn’t magically erase spiders from the planet,” laughs Claire, a renter in Leeds who swears by it every autumn. “It just lets me feel like I have some control. I’d rather my house smell like toothpaste than spend every evening chasing spiders with a glass.”

Treat peppermint oil as one helpful option in a small, sensible toolkit, not a magic fix. For longer-lasting results, combine it with a few practical habits:

• Vacuum corners, ceilings and behind furniture regularly to clear webs and egg sacs.
• Seal obvious gaps around windows, doors and pipes where you can see daylight.
• Keep outdoor lights softer or angled down - bright lighting attracts insects, which attracts spiders.
• Place peppermint-soaked cotton pads behind furniture or near vents for persistent spots.
• Alternate with other strong scents such as eucalyptus or citrus if you become used to the smell.

On a quiet night, with the wind kept out by closed windows and the lights turned down, a spider-free house feels strangely peaceful. As you pass through the hallway, there’s that faint mint note again - a reminder of a small, repeatable ritual with a spray bottle. No drama, no harsh chemicals, just a tiny choice made often.

In shared-flat group chats, tips like this spread quickly. Someone posts a photo of a “monster” in the bath; someone else replies with a stock image of peppermint oil and a row of laughing emoji. Gradually, the mood shifts from “we need to nuke them” to “maybe we can nudge them back outside”.

Most people know that moment of freezing in a doorway, deciding whether to grab a glass, a shoe, or simply retreat and pretend it never happened. Peppermint oil doesn’t remove that instinctive flinch - it just makes it less frequent.

There’s a quiet satisfaction in reclaiming your home with something that fits in the palm of your hand. No traps, no guilt about squashing anything, no chemical odour hanging about for hours. Just a sharp green scent that says: this space is taken.

FAQ:

• Does peppermint oil actually get rid of spiders? It doesn’t kill them, but the strong smell can push them away from treated areas and make it less appealing for new ones to settle indoors.
• How often should I spray peppermint oil around the house? Begin with once a week during spider season, then top up every 10–14 days as the scent fades or after cleaning.
• Is peppermint oil safe for pets and children? When diluted and used sparingly, it’s generally fine, but avoid contact with skin, paws or mouths, and never apply it neat to surfaces they might lick.
• Can I just use a peppermint-scented cleaner or candle? Most fragranced products are too mild; you usually need pure essential oil diluted in water or applied to cotton pads to create a scent strong enough to bother spiders.
• Where is the best place to put peppermint oil if I hate spiders in the bedroom? Lightly spray the skirting boards, window frame and door frame, and tuck a peppermint-soaked cotton pad behind bedside tables or near plug sockets.
