So, does Vicks VapoRub repel spiders?
The answer is possibly for some situations, but there is no strong scientific evidence confirming it as a reliable spider repellent. If you decide to try it, think of it as an unproven home remedy rather than a guaranteed solution.
The most dependable way to reduce spiders remains a combination of good housekeeping, sealing entry points, reducing insect prey, and maintaining your home’s exterior.
Sometimes, the oldest household tricks are interesting to explore—but it’s always helpful to separate tradition from evidence when deciding what really works.
