The Truth About This Viral Home Remedy
A small tub of Vicks VapoRub has become an unlikely star of social media, with homeowners claiming that rubbing a little of the mentholated ointment around windows, doors, and other entry points can help keep spiders away.
It sounds almost too simple.
No complicated traps. No harsh-smelling insecticide. Just a familiar household product and a few strategic dabs.
But does it actually work?
The answer is more complicated than many viral posts suggest.
Vicks VapoRub may make an area less appealing to some spiders because of its strong odor, but there is not strong evidence that Vicks itself is a reliable or scientifically established spider repellent.
That distinction matters.
If you're dealing with a few unwanted eight-legged visitors, there are better-supported ways to make your home less attractive to spiders—and most of them are surprisingly simple.
Why Do People Think Vicks Repels Spiders?
Vicks VapoRub contains strongly scented ingredients, including menthol, camphor, and eucalyptus oil.
Because spiders rely heavily on chemical and tactile sensory information from their legs and other sensory structures, the idea that powerful odors could influence their behavior is biologically plausible.
But plausible isn't the same thing as proven.
There is a big difference between showing that a particular essential oil can affect spider behavior under experimental conditions and proving that rubbing a commercial vapor rub around your house will reliably keep household spiders away.
At the moment, there isn't good evidence establishing Vicks VapoRub as a dependable spider-control product.
So if someone says, "Vicks definitely keeps spiders away," that's stronger than the available evidence supports.
What Happens If You Put Vicks Around a Window?
Suppose you rub a small amount around a windowsill.
The strong smell may make that particular area temporarily less attractive to some spiders. But several things can happen:
The odor gradually becomes weaker.
Air movement disperses the volatile compounds.
Different spider species may respond differently.
A spider may simply choose another route into the home.
Vicks does nothing to eliminate the insects that spiders feed on.
In other words, even if the trick works in one house, that doesn't mean it creates a reliable invisible barrier around the entire building.
That's why it's better to think of Vicks as an unproven household deterrent, rather than a proven pest-control method.
The Bigger Question: Why Are Spiders Coming Inside?
This is where things get interesting.
If you repeatedly see spiders around your windows, doors, basement, garage, or other parts of the house, the underlying problem may not actually be the spiders.
Your home may simply be providing what they need.
Spiders enter buildings through cracks and openings, and they are often attracted to places where prey insects are abundant. Extension and pest-management experts recommend addressing those conditions rather than relying on a single repellent.
That means the most effective strategy is usually not:
"What can I put on the windowsill?"
It's:
"Why can spiders get in, and why do they want to stay?"
5 Things That Actually Help Reduce Spiders
1. Seal the Gaps Around Your Home
This is one of the most useful steps you can take.
Check around:
Windows
Exterior doors
Door thresholds
Pipes and utility openings
Foundation cracks
Vents
Damaged screens
Seal appropriate cracks and gaps with caulk or another suitable material, and make sure exterior doors and windows close tightly.
The National Pesticide Information Center specifically recommends sealing cracks and crevices around foundations, doors, and windows because these openings can provide spiders with access to the home.
A simple door sweep can also help close the gap beneath an exterior door.
2. Vacuum Webs, Spiders, and Egg Sacs
If you regularly find webs in corners, behind furniture, around windows, or in storage areas, remove them.
Vacuuming can physically remove spiders, webs, and egg sacs while also reducing the places where spiders establish themselves.
The University of California's integrated pest-management guidance recommends regular sweeping, mopping, and vacuuming as part of indoor spider management.
Don't just focus on the visible web.
Look around:
Ceiling corners
Window frames
Behind furniture
Under appliances
Basements
Garages
Closets
Undisturbed storage areas
Regular cleaning can make these spaces less attractive to spiders.
3. Reduce Their Food Supply
This is one of the most overlooked parts of spider control.
Spiders eat insects.
If your house has lots of flies, moths, mosquitoes, ants, or other small insects, you've effectively created a food supply for spiders.
Reducing those insects can therefore reduce the reason spiders have to remain nearby.
Experts recommend addressing insect activity as part of an overall spider-management strategy.
Outdoor lighting can also contribute indirectly. Bright exterior lights attract insects, which can in turn attract spiders.
If practical, reduce unnecessary outdoor lighting or use lighting options that are less attractive to flying insects.
4. Reduce Clutter and Hiding Places
Spiders prefer quiet, undisturbed areas.
Stacks of cardboard boxes, piles of stored items, wood, debris, and clutter around foundations can create excellent hiding places.
Keep storage areas organized and avoid allowing boxes and other materials to accumulate unnecessarily.
Outdoor clutter matters too.
Firewood, leaves, rocks, boards, dense vegetation, and other materials close to the house can provide shelter for spiders and their prey.
Think of it as making your home less attractive rather than trying to chase every spider away individually.
5. Keep Plants From Touching the House
Trees, shrubs, vines, and other vegetation that directly touches the exterior can provide pathways for insects and spiders to reach the building.
Trim vegetation back where practical, particularly around windows, doors, and the foundation.
This won't eliminate spiders from your garden—and it shouldn't.
Spiders are important predators that help control many insect populations.
The goal is simply to create a little more separation between outdoor spider habitat and your living space.
What About Peppermint and Other Essential Oils?
You've probably seen another version of the viral spider-repellent trick involving peppermint oil, tea tree oil, citrus oils, or other strongly scented essential oils.
These remedies are popular online because they are inexpensive and easy to try.
But again, popular doesn't automatically mean proven.
Some laboratory studies have investigated how particular plant-derived chemicals affect arthropod behavior, but household conditions are much more complicated. Concentration, species, ventilation, temperature, and how long the odor remains detectable can all affect the outcome.
So rather than promising that a particular essential oil "will keep every spider away," it's more accurate to say that scent-based repellents may have limited or inconsistent effects.
If you choose to experiment with one, don't let it replace the basics: sealing openings, reducing clutter, removing webs, and controlling insects.
Can Vicks VapoRub Kill Spiders?
You shouldn't treat Vicks as a spider killer.
Vicks VapoRub is a topical medicinal product, not a pesticide labeled for spider control.
Putting it on a spider isn't a reliable pest-control strategy, and deliberately exposing pets or children to the product can create unnecessary risks.
If you're using any household product around children or animals, follow its label and keep it out of their reach.
For actual pest-control products, use only products specifically labeled for the intended pest and location, and follow the label instructions.
Is Vicks Safe Around Pets?
This is another reason not to go overboard with the viral trick.
Vicks contains aromatic ingredients that can be irritating, and household products should not be placed where pets can lick, chew, or otherwise contact them.
If you have cats, dogs, young children, or other animals in the home, don't treat a viral hack as automatically safe just because the product is commonly found in medicine cabinets.
Use the manufacturer's directions and keep the product inaccessible to children and pets.
What If You Already Have a Lot of Spiders?
Seeing an occasional spider indoors is normal.
In fact, several university extension programs point out that spiders are beneficial predators and that eliminating every spider from a home is usually unnecessary.
But a large or persistent spider population deserves a closer look.
Instead of immediately spraying everything, investigate:
Where are they appearing?
What insects are they feeding on?
Are there cracks or damaged screens?
Is there excessive clutter?
Are there damp or undisturbed areas?
Is vegetation touching the building?
Finding the answer can be much more effective than repeatedly applying a scented substance.
When Should You Consider Professional Pest Control?
If you're seeing unusually large numbers of spiders, repeatedly finding potentially medically significant species, or dealing with an infestation that doesn't improve after exclusion and cleaning, professional advice may be appropriate.
A qualified pest professional can help identify the species and locate areas where spiders or their prey are entering or hiding.
For ordinary household spider activity, however, integrated pest management—exclusion, sanitation, habitat modification, and targeted treatment when necessary—is generally a better approach than relying on one home remedy.
So, Does the Vicks Trick Really Work?
Here's the honest answer:
Maybe a little, sometimes—but don't count on it.
The strong smell of Vicks makes the idea plausible as a temporary deterrent, but there isn't strong evidence that Vicks VapoRub is a reliable spider repellent.
If you enjoy using it as an extra precaution and it doesn't create a safety problem in your home, a small amount may be harmless in an appropriate location.
But don't expect it to solve a spider problem.
The boring solutions are actually the ones with the strongest practical support:
Seal the gaps.
Repair the screens.
Vacuum the webs.
Reduce clutter.
Control insects.
Trim vegetation away from the house.
Those steps address the reasons spiders get inside and stick around.
The Bottom Line
The internet loves a household hack because it promises a simple answer to an annoying problem.
A little vapor rub around the windows sounds wonderfully easy.
But when it comes to spiders, the evidence doesn't justify calling Vicks VapoRub a proven repellent.
If it seems to help in your home, great—but think of it as an optional experiment rather than your main line of defense.
For lasting results, make your home harder for spiders to enter and less attractive once they're inside.
And remember: most spiders aren't looking for you.
They're looking for the insects that are already inside your house.
So instead of declaring war on every eight-legged visitor, focus on making your home a less convenient place for them to live.
Sometimes the best spider repellent isn't something you put on the windowsill.
It's a well-sealed window.
