Every few months, an old household trick makes its way back onto social media, capturing the attention of millions. One of the latest to go viral involves a product that has been found in medicine cabinets for generations: Vicks VapoRub.
The claim is simple but intriguing. According to countless posts shared across Facebook, TikTok, and other social platforms, applying a small amount of Vicks VapoRub around doors, windows, or other entry points can supposedly help keep spiders from entering your home.
Some people swear by it. Others dismiss it as nothing more than an internet myth.
So, what’s the real story?
Is Vicks VapoRub actually an effective natural spider repellent, or is this just another viral home remedy that sounds too good to be true?
Let’s take a closer look at where this idea comes from, what science says, and whether it’s worth trying.
Why This Household Trick Has Everyone Talking
Many people grew up seeing a jar of Vicks VapoRub on the bathroom shelf. Traditionally, it has been used to temporarily relieve coughs, nasal congestion, and minor muscle aches thanks to ingredients such as menthol, camphor, and eucalyptus oil.
Over the years, however, people have discovered dozens of alternative uses for the familiar ointment.
Some claim it helps deter mosquitoes.
Others believe it keeps ants away.
And perhaps the most popular claim today is that spiders dislike its strong scent.
Stories often begin with someone sharing advice from a parent or grandparent.
“My grandmother always rubbed Vicks around the windows.”
“My neighbor puts it around every doorway.”
“I haven’t seen a spider since I started using it.”
These personal experiences have helped the idea spread rapidly online.
But personal stories don’t always tell the whole story.
Why People Think It Might Work
The theory behind the hack is fairly simple.
Vicks contains several aromatic ingredients, including:
- Menthol
- Camphor
- Eucalyptus oil
- Cedar leaf oil
- Turpentine oil
These ingredients produce a very strong smell that humans easily recognize.
Some insects and animals are sensitive to powerful odors, leading many people to believe spiders may avoid areas where these scents are present.
It’s certainly a plausible idea.
However, plausibility isn’t the same as scientific proof.
What Research Says About Spider Repellents
At the moment, there is very little scientific research specifically testing Vicks VapoRub as a spider repellent.
While certain essential oils have shown limited ability to discourage some insects under laboratory conditions, spiders behave differently from insects.
Some studies suggest that peppermint oil, citrus oils, or eucalyptus oil may temporarily discourage certain spider species because of their strong scent.
Since Vicks contains eucalyptus oil and menthol, some people assume it would have a similar effect.
However, scientists have not established that applying Vicks around doors or windows consistently prevents spiders from entering homes.
In other words:
It might discourage some spiders for a short period because of its odor, but there is currently no strong scientific evidence proving it works reliably.
Why Some People Believe It Works
There are several reasons someone might think Vicks solved their spider problem.
Seasonal Changes
Spider activity naturally rises and falls throughout the year.
If someone applies Vicks just as spider season is ending, they may incorrectly assume the ointment caused the decrease.
Cleaning at the Same Time
Many people who try home remedies also clean corners, remove webs, seal cracks, and organize storage areas.
These actions alone can dramatically reduce spider activity.
