l Spiders
Let me explain the science behind the claim.
Vicks VapoRub contains several strong-smelling ingredients:
Menthol (from peppermint oil)
Camphor
Eucalyptus oil
Cedarleaf oil
Thymol (from thyme oil)
Spiders are not insects—they’re arachnids. But like many arthropods, they rely heavily on chemical signals (pheromones) and sensory receptors to navigate their environment, find food, and detect danger.
Strong, pungent odors can overwhelm or disrupt these sensory systems. The theory is that spiders find the intense menthol-camphor-eucalyptus combination unpleasant or disorienting, so they avoid areas where the smell is concentrated.
Does this work for all spiders? Probably not. Some spiders may be less sensitive. Some may not care. But many people report success with menthol-based repellents.
Is it scientifically proven? There are no large-scale studies testing Vicks specifically as a spider repellent. But the individual ingredients (peppermint oil, eucalyptus oil) have some anecdotal and limited scientific support as insect and arachnid repellents.
The bottom line: It’s not a guaranteed solution, but it’s cheap, safe, and worth a try.
My Experiment: Vicks vs. The Spider Invasion
I bought a small blue jar of Vicks VapoRub (the original formula—not the generic, not the lavender-scented version). I didn’t want to smear it directly on my windowsills (the greasy residue would collect dust), so I got creative.
My method: I dabbed small amounts of Vicks onto cotton balls—about the size of a pea per cotton ball. I placed them in discreet locations: behind curtains, on windowsills, under the couch, in the corners of closets, near the basement door.
The result: Within a few days, I noticed fewer spiders. Not zero—but noticeably fewer. I wasn’t finding a new one every morning. By the end of the week, the invasion had subsided.
I can’t prove it was the Vicks. Maybe spider season was ending. Maybe they’d moved on to terrorize someone else. But I was grateful. And I’ve continued using Vicks-soaked cotton balls in problem areas ever since.
The house still smells faintly of menthol. It’s not my favorite scent. But it beats waking up to a spider on my pillow.
How to Use Vicks VapoRub as a Spider Repellent (Practical Tips)
If you want to try this method, here’s what worked for me.
What You’ll Need:
Original Vicks VapoRub (blue jar)
Cotton balls
Small dishes or bottle caps (optional)
Gloves (if you don’t like getting greasy fingers)
Step-by-Step:
Step 1: Put a small dab of Vicks on a cotton ball (about the size of a pea). You don’t need much. A little goes a long way.
Step 2: Place the cotton ball in areas where you’ve seen spiders: windowsills, behind furniture, in corners, near doors, in the basement, in the garage.
Step 3: For areas where a cotton ball might roll away, use a small dish or a bottle cap to hold it.
Step 4: Reapply every 2-3 weeks, or when the scent fades.
Where NOT to Use Vicks:
Directly on wood or unfinished surfaces: The oils can stain.
Where children or pets can reach: Vicks can be toxic if ingested in large amounts. Keep cotton balls out of reach.
On fabric: Grease stains are hard to remove.
Alternative Method (Less Greasy):
If you don’t want cotton balls everywhere, mix a few drops of menthol, eucalyptus, and camphor essential oils with water in a spray bottle. Spray along baseboards, windowsills, and door frames. This is less messy but may need more frequent reapplication.
Other Natural Spider Repellents (That Actually Work)
Vicks isn’t your only option. Here are other natural deterrents with some evidence behind them.
Peppermint Oil (Most Popular)
Why it works: Spiders and many insects dislike strong mint odors. Peppermint oil contains compounds that may overwhelm their sensory receptors.
How to use: Mix 10-15 drops of peppermint essential oil with 1 cup of water in a spray bottle. Add a drop of dish soap to help emulsify. Spray along baseboards, windowsills, door frames, and in corners.
Reapply weekly.
Vinegar (Cheap and Effective)
Why it works: Vinegar’s strong acetic acid smell is unpleasant to spiders.
How to use: Mix equal parts white vinegar and water in a spray bottle. Spray directly on spiders (it will kill them) or as a deterrent in problem areas.
Downside: Your house will smell like vinegar. The smell fades after a few hours.
Cedar
Why it works: Cedar contains natural oils that repel moths, spiders, and other pests.
How to use: Place cedar blocks, cedar chips, or cedarwood balls in closets, drawers, and corners. Use cedar oil in a diffuser or spray.
Bonus: Cedar smells lovely.
Citrus Peels (Old Wives’ Tale with Some Merit)
Why it works: Spiders are said to dislike citrus. Limonene (a compound in citrus peels) is toxic to some insects.
How to use: Rub citrus peels along baseboards and windowsills. Or boil citrus peels in water and use the cooled liquid as a spray.
Downside: Peels dry out and lose potency quickly. Replace weekly.
Diatomaceous Earth (DE)
Why it works: This fine powder is made from fossilized algae. It damages the exoskeletons of insects and arachnids, causing them to dehydrate and die.
How to use: Lightly dust DE in corners, along baseboards, behind appliances. Use a bulb duster for precision.
Important: Use food-grade DE (not pool-grade). Wear a mask when applying (the dust is irritating to lungs). Keep away from pets and children.
What About Chemical Spiders Repellents?
If natural methods don’t work, you can use commercial products. But use them carefully.
Pros: Very effective, long-lasting.
Cons: Toxic to pets and children, harmful to beneficial insects, may have health risks with prolonged exposure.
If you use chemical repellents:
Follow label instructions exactly.
Keep pets and children away during application.
Ventilate the area.
Store safely.
For most homes, a combination of physical prevention (sealing cracks, cleaning webs) and natural repellents is sufficient.
Prevention: Keep Spiders Out in the First Place
Repellents are a bandage. Prevention is the cure.
Seal entry points: Use caulk to seal cracks around windows, doors, pipes, and vents. Install door sweeps. Repair torn screens.
