Does Vicks VapoRub Actually Work as a Spider Deterrent? The Truth About This Viral Trick

My neighbor is a 78-year-old lady who has been keeping house for longer than I’ve been alive. Every morning, she seems to have a little routine for everything: opening the windows, wiping down the kitchen counters, watering her plants, and, for some reason I never understood, putting a small amount of Vicks VapoRub around her front door.

One day, I finally asked her why.

She looked at me as if I had just asked her why people wash their hands.

Then she smiled and said something along the lines of, “Young people don’t know the old housekeeping tricks anymore.”

That only made me more curious.

I knew Vicks VapoRub as the familiar mentholated ointment people rub on their chest when they have a cold or stuffy nose. I had never thought of it as a household pest deterrent.

But apparently, there is a popular belief that Vicks VapoRub can help keep spiders away.

So, does it actually work?

Or is this just another internet household hack that sounds convincing because it has been repeated thousands of times?

The answer is a little more complicated than a simple yes or no.

Why Do People Think Vicks Keeps Spiders Away?

The theory behind the trick is fairly straightforward.

Vicks VapoRub has a strong smell, largely because of aromatic ingredients such as menthol, camphor, and eucalyptus oil. Humans tend to associate that distinctive scent with cold remedies, but strong fragrances can also affect insects and other small creatures.

This has led to a common household belief: if you put Vicks around doors, windows, cracks, or other places where spiders might enter, the powerful smell will discourage them from crossing the area.

The idea is similar to other DIY pest-control methods involving strongly scented substances.

People commonly recommend things such as peppermint oil, eucalyptus, citrus peels, vinegar, or various essential oils as natural spider repellents. The basic reasoning is that spiders rely heavily on sensory information to navigate their surroundings, and strong odors might make an area less appealing.

That sounds reasonable.

But there is an important distinction between something being plausible and something being scientifically proven.

And that is where the Vicks story gets interesting.

What Is Actually Inside Vicks VapoRub?

To understand why the trick might work—or might not—we need to look at what Vicks actually contains.

Vicks VapoRub is a topical ointment formulated with aromatic compounds, including menthol, camphor, and eucalyptus oil. These ingredients are responsible for much of its recognizable smell.

Menthol produces the familiar cooling sensation. Camphor has a strong aromatic odor and has long been used in various traditional remedies. Eucalyptus oil also has a powerful, distinctive fragrance.

Those ingredients are not specifically designed to repel spiders.

Vicks is a medicinal product intended for external use, particularly for temporary relief from cough associated with the common cold.

So if it happens to discourage spiders, that would be more of a side effect of its strong odor than its intended purpose.

This is an important point because household advice often gets repeated until the original explanation becomes blurred.

Someone notices fewer spiders after using Vicks.

They tell a friend.

The friend tells another person.

Eventually, the story becomes, “Vicks repels spiders.”

But there is a big difference between an observation and controlled scientific evidence.

Do Spiders Actually Hate the Smell?

This is the part that gets surprisingly complicated.

Spiders do have highly developed sensory systems. They can detect vibrations, air movement, chemicals, and other environmental signals. Their legs contain sensory structures that help them gather information about their surroundings.

However, spiders aren't simply walking around thinking, “That smells terrible—I’m leaving.”

Their reactions to chemicals can vary depending on the species, concentration of the substance, environmental conditions, and whether the chemical actually reaches the sensory structures that matter.

There is some scientific research into how spiders respond to various odors and chemicals, but that does not mean every strong-smelling household product has been proven to repel spiders.

In other words, the fact that Vicks smells extremely strong to us doesn't automatically mean it acts as an effective spider barrier.

That assumption is one of the biggest problems with viral pest-control hacks.

So, Does Vicks VapoRub Repel Spiders?

The most accurate answer is:

There is not enough reliable scientific evidence to say that Vicks VapoRub is a proven or dependable spider repellent.

That doesn't necessarily mean the trick is completely useless.

Some people may genuinely notice fewer spiders after applying it, particularly around small entry points such as doors and windows.

The strong aromatic ingredients could potentially make certain areas less attractive to some spiders.

But that is very different from saying that Vicks creates a reliable “spider-proof” barrier.

If you smear Vicks around your front door today, there is no guarantee that spiders will stay away tomorrow.

A spider may simply walk through it.

Another spider may avoid the area.

A third may never have been affected at all.

And because different spider species behave differently, results can vary considerably.

So if your neighbor swears by the method, she may not necessarily be imagining the results. But personal experience alone doesn't establish that Vicks is a scientifically proven pest-control treatment.

Why the Trick Might Seem to Work

There is another possibility that is easy to overlook.

Sometimes a household hack appears to work because the conditions surrounding the problem have changed.

Suppose someone puts Vicks around their doors and notices fewer spiders a few days later.

They naturally assume the Vicks caused the change.

But what if the weather became colder?

What if insects became less active?

What if the person cleaned the area?

What if a nearby light that attracted insects was switched off?

What if the spiders simply moved somewhere else?

Spiders don't remain in exactly the same place all the time. Their activity changes according to temperature, food availability, shelter, moisture, and environmental conditions.

This means that a simple before-and-after observation can be misleading.

The Vicks may have contributed—or it may have had little or nothing to do with the change.

What About Putting Vicks Around Doors and Windows?

This is probably the most common version of the trick.

People apply a small amount of Vicks around door frames, window frames, baseboards, vents, or other potential entry points.

The idea is that the strong smell forms an invisible boundary that spiders won't want to cross.

Again, there is no strong evidence that this creates a dependable barrier.

There is also a practical problem: Vicks is an oily ointment.

Applying it to painted surfaces, wood, fabric, or other materials could leave behind a greasy residue. Over time, it can collect dust and dirt, which may create more cleaning work rather than less.

If you do use it around the house, it makes more sense to think of it as an experiment rather than a guaranteed pest-control solution.

And remember that Vicks is intended for external use on the body according to its product directions—not as a household pesticide.

What Really Helps Keep Spiders Out?

If you're dealing with a genuine spider problem, there are much more dependable steps you can take.

1. Seal Cracks and Gaps

This is one of the most effective approaches.

Spiders often enter buildings through tiny gaps around doors, windows, pipes, vents, foundations, and other openings.

Inspect the exterior of your home and look for cracks or spaces where small creatures could enter.

Caulk small cracks around windows and other appropriate areas, repair damaged screens, and make sure doors close tightly.

Stopping entry is generally more reliable than trying to repel spiders after they have already found their way inside.

2. Reduce Outdoor Lighting Near Doors

Outdoor lights can attract insects.

And where there are plenty of insects, there can be plenty of spiders looking for food.

If possible, reduce unnecessary lighting around entrances or use lighting designed to be less attractive to insects.

This won't eliminate spiders completely, but it can reduce the amount of prey available near your doors and windows.

3. Keep the House Clean

Regular cleaning can remove webs, egg sacs, and hiding places.

Pay particular attention to corners, ceilings, basements, garages, storage areas, and spaces behind furniture.

Vacuuming regularly can also help remove spiders and their webs.

This is less glamorous than a viral household hack, but it is considerably more practical.

4. Reduce Clutter

Spiders love quiet, undisturbed spaces.

Boxes piled in a garage, stacks of newspapers, unused clothing, piles of wood, and cluttered storage areas can all provide shelter.

Keeping storage areas organized makes it harder for spiders to establish comfortable hiding places.

5. Control Other Insects

Remember that spiders are predators.

If your home has a large population of flies, moths, mosquitoes, ants, or other small insects, it may become attractive to spiders simply because there is plenty of food.

Addressing the underlying insect problem can therefore make your home less appealing to spiders.

Are Natural Spider Repellents Better?

You may have heard that peppermint oil or eucalyptus oil is a better natural alternative.

Some research has investigated essential oils and their effects on arthropods, and certain strong-smelling oils may have repellent properties against particular species.

However, “natural” doesn't automatically mean “effective,” and it doesn't mean something will work against every type of spider.

Concentration matters.

Application method matters.

Species matters.

Environmental conditions matter.

And even if an essential oil temporarily discourages a spider from one area, it may not solve the underlying reason spiders are entering your home.

Natural products can also irritate skin or cause problems for pets if used improperly.

So it's best to be cautious with concentrated essential oils, particularly around children and animals.

Why Do These Old-Fashioned Tricks Become So Popular?

There is something fascinating about household wisdom passed down through generations.

Older generations often had fewer specialized products available to them. Instead of immediately reaching for a commercial pesticide, they frequently experimented with everyday household ingredients.

Some of those tricks were surprisingly useful.

Others probably worked only under specific circumstances.

And some became traditions even when nobody remembered exactly why they started.

That's likely part of what makes the Vicks story so appealing.

It's inexpensive.

It's already sitting in many medicine cabinets.

It has an unmistakably strong smell.

And unlike a complicated pest-control system, the method is incredibly simple.

You don't need special equipment.

You don't need to mix anything.

You simply apply a little around an area and see what happens.

For a person who has used the trick successfully for years, that's enough evidence to keep doing it.

And honestly, that's understandable.

The Problem With Viral Household Hacks

The internet has transformed ordinary household tricks into viral “secrets.”

A simple claim such as “Put Vicks around your door and spiders will never enter again” sounds much more exciting than the reality.

The problem is that these claims often leave out important details.

How many spiders were there before?

What species were they?

How long did the effect last?

Was there a control group?

Was the Vicks compared with another strong-smelling substance?

Did the number of spiders actually decrease, or did they simply move?

Without answers to questions like these, it's difficult to determine whether the remedy genuinely works.

That's why it's important to be skeptical without automatically dismissing traditional knowledge.

Sometimes an old household trick contains a useful idea.

Sometimes it doesn't.

The best approach is to ask what evidence supports it and whether there is a safer, more reliable way to accomplish the same goal.

Should You Try Vicks for Spiders?

If you already have Vicks at home and want to test whether its smell seems to discourage spiders in a particular area, there's no reason to treat the idea as magical.

Just don't rely on it as your primary pest-control strategy.

Think of it as an unproven household experiment rather than a guaranteed solution.

More importantly, don't spread the idea that Vicks can eliminate a spider infestation.

It can't.

If you're seeing one or two spiders occasionally, simple housekeeping, sealing entry points, and removing webs may be enough.

If you're seeing large numbers of spiders or repeatedly finding them throughout your home, it's worth investigating why they're there.

There may be an underlying moisture problem, an abundance of insects, structural gaps, or a sheltered nesting area.

Addressing that cause will usually be much more effective than trying to make the house smell strongly of menthol.

And What About My Neighbor?

After learning more about the Vicks trick, I have to admit that I understand my neighbor a little better.

For her, this isn't necessarily about scientific proof.

It's about decades of experience.

She has lived through enough seasons to know what seems to work in her own home. Maybe the Vicks actually discourages some spiders. Maybe the smell simply makes her feel like she is doing something useful. Maybe she inherited the trick from someone older and has never had a reason to question it.

And perhaps that's the most interesting part of the story.

Housekeeping knowledge doesn't always arrive in a scientific journal.

Sometimes it comes from a grandmother.

Sometimes it comes from a neighbor.

Sometimes it comes from watching what happens in the same house for 50 years.

But when an old trick becomes a viral internet claim, it's worth separating the tradition from the evidence.

The Bottom Line

So, does Vicks VapoRub actually work as a spider deterrent?

Maybe for some spiders, in some circumstances—but there isn't enough solid evidence to call it a reliable spider repellent.

Its strong-smelling ingredients may make certain areas less attractive to some spiders, but Vicks was not designed or proven to function as a household spider pesticide.

If you want to reduce spiders, focus on the basics: seal cracks and gaps, repair screens, reduce clutter, clean webs regularly, manage other insects, and minimize conditions that attract spider prey.

And if you decide to try the Vicks trick anyway, don't expect a miracle.

As for my 78-year-old neighbor?

I'm not going to tell her she's wrong.

After all, she's been keeping house for several decades longer than I have.

Maybe the real lesson isn't that every old housekeeping trick is scientifically proven.

Maybe it's that sometimes the people who have been doing something for years have a reason—even if they don't explain it in the language of a scientific study.

Still, next time she puts Vicks around her front door, I might ask her where she learned the trick.

I'm beginning to suspect there's a whole collection of old-fashioned housekeeping secrets hiding in that little jar.
