How to Use Peppermint Oil to Keep Spiders Out of Your Home

The first spider appeared on the bathroom ceiling, plump and motionless, directly above the mirror.

An hour afterwards, a slimmer one was waiting in the hallway corner, exactly where the night light casts its soft orange glow. Same home, same day, and the same little lurch in your stomach whenever eight legs seemed to materialise from nowhere.

That evening, the windows were shut, the heating was running, and the air carried a faint mix of laundry detergent and toast. The garden outside was wet and dark. Indoors, though, there was clearly something drawing them in.

A neighbour suggested a remedy that sounded more like a TikTok tip than practical advice: “Just use peppermint oil, they hate it.” She said it as she wiped her hands on her jeans, as though it were completely ordinary.

By the following day, the entire house smelled of mint sweets. That was when it started to get interesting.

Why spiders hate that fresh peppermint smell

The first thing that strikes you after spraying peppermint oil in a room is the immediate freshness. It is sharp and nearly icy, rather like stepping outdoors on a frosty morning. The crisp fragrance that helps wake you up has a very different effect on spiders.

Spiders investigate your home through their legs and fine hairs, picking up chemical traces in the air. Peppermint does not politely encourage them to leave; it overwhelms them. Wrong place. Wrong smell. Turn back.

While you may think, “my house smells like chewing gum”, a spider may interpret it as, “this territory is hostile”. It all appears perfectly normal: skirting boards, window frames and sockets. At a microscopic level, however, you have effectively redrawn the boundaries of your home.

During a damp October night in Manchester, one family tried it partly as a joke. The mum took an inexpensive spray bottle, filled it with water, added a generous splash of peppermint oil, and lightly sprayed the living room, hall and bedroom door frames. She targeted the familiar problem spots: the gap beneath the front door, the corner beside the shoe rack, and the window with its damaged seal.

For several weeks, they had been catching one or two house spiders each day. They were large ones too – the sort that suddenly dash over the carpet while you are watching a film. Nobody was logging the sightings in a spreadsheet, but they had the mental tally every householder recognises: “Why are there so many this year?”

Over the following three nights, the situation changed. An occasional web still turned up by the kitchen window, but the large runners in the hallway had disappeared. She continued to spot the odd tiny spider high up, yet the surge had ended. There were no chemicals and no sticky traps, only a home now carrying the faint scent of an upmarket candle shop.

There is a straightforward, if slightly unglamorous, explanation for this. Spiders do not enter your home out of spite. They follow food, dampness and dark, undisturbed spaces. Your house is simply a comfortable extension of the garden.

Peppermint oil does not kill spiders. Instead, it disrupts the signals they depend on. Its powerful smell conceals the trails and cues they use for finding their way, hunting and hiding. It is like trying to trace a subtle perfume through a room full of burning incense – eventually, your senses simply stop working.

That is why adding a few drops to a diffuser is unlikely to achieve much. Success depends on both the strength of the fragrance and where it is placed. The aim is not to make your home feel like a spa; it is to create an unseen minty barrier.

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

Keep the ingredients simple: a small spray bottle, a bottle of pure peppermint essential oil and standard tap water. Fill the bottle nearly to the top with water, then add roughly 10–15 drops of peppermint oil per 250 ml. Shake it thoroughly until the water becomes slightly cloudy and the bottle smells strongly of mints.

Move slowly through the house, spraying skirting boards, window sills, door frames and, in particular, those familiar corners where webs usually appear. Do not drench the surfaces – a light mist is enough, leaving a faint sheen for a minute or two. Give priority to access points, including gaps around the letterbox, vents, cracks and the narrow line where the carpet meets the wall.

Apply it weekly to begin with, then refresh it every couple of weeks as the scent weakens. Let’s be honest: nobody really does this every day.

This is where many people lose heart: they use it once, fail to see an instant miracle and stop. Others make the mixture too weak, then wonder why it has made no difference. In reality, you are working against habits – your own as well as the spiders’.

If you have pets or young children, use it cautiously. Apply a light spray to low-level areas and avoid saturating fabrics that they might lick or chew. You need a noticeable scent, not a slippery floor or irritated skin. Always test a small hidden patch on painted walls or polished wood first, as undiluted peppermint oil can occasionally leave light marks.

A frequent mistake is overlooking clutter. A peppermint barrier along the skirting board will have limited effect if a stack of boxes has become an ideal spider hotel. Pair your mint routine with a quick tidy-up, tackling one room at a time. It does not need to be a deep clean; simply move that “I’ll sort 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 useful item in a small, practical toolkit rather than a magic solution. For longer-lasting results, combine it with a few easy habits:

• Vacuum corners, ceilings and behind furniture regularly to clear away webs and egg sacs.
• Seal noticeable gaps around doors, windows and pipes where daylight is visible.
• Keep exterior lighting soft or directed downwards – bright lights attract insects, which in turn attract spiders.
• Put peppermint-soaked cotton pads behind furniture or near vents in persistent problem areas.
• Alternate it with other strong scents, such as eucalyptus or citrus, if you become tired of the smell.

On a peaceful evening, with windows closed against the wind and the lights turned down, a spider-free home can feel unexpectedly restful. As you pass through the hallway, you notice the slight scent of mint and remember that small spray-bottle ritual. No drama, no chemicals, just one small choice repeated over time.

In a shared-flat group chat, tips like this spread quickly. One person shares a photo of a “monster” in the bath, while someone else replies with a stock image of peppermint oil and a string of laughing emojis. Gradually, the thinking changes from “we need to nuke them” to “maybe we can nudge them back outside”.

We have all had the moment of freezing in the doorway, deciding whether to reach for a glass, a shoe or simply walk away and act as though we saw nothing. Peppermint oil does not remove that instinctive flinch. It just makes it happen less frequently.

There is something quietly pleasing about taking your home back with something small enough to hold in your hand. No traps, no guilt over crushing anything, and no chemical odour lingering for hours. Just a sharp green scent declaring: this space is taken.

FAQ:

• Does peppermint oil really remove spiders? It does not kill them, but the intense smell may push them away from treated spots and make new spiders less likely to settle indoors.
• How frequently should peppermint oil be sprayed around the home? Begin with one application a week during spider season, then reapply every 10–14 days as the scent fades or after cleaning.
• Is peppermint oil suitable around pets and children? When diluted and used sparingly, it is generally fine, but prevent direct contact with skin, paws and mouths, and never apply it neat to surfaces they may lick.
• Could a peppermint-scented cleaner or candle work instead? Most fragranced products are too mild; pure essential oil mixed with water or applied to cotton pads is needed to create a smell strong enough to deter spiders.
• Where should peppermint oil go if spiders in the bedroom are a concern? Mist the skirting boards, window frame and door frame lightly, then place a peppermint-soaked cotton pad behind bedside tables or close to plugs.
