Although many of these eight-legged creatures are harmless, that doesn’t mean you want to share your space with them. You may have heard the peppermint oil spiders myth, which posits that this everyday household item keeps them at bay. Is this claim fact or fiction? Let’s take a look. Does Peppermint Oil Keep Spiders Away? We’ll go right ahead and answer this burning question: yes, you can use peppermint oil for spiders! It’s a popular natural remedy that can help you stop these pests from entering your house. Many people have had success in keeping spiders at bay through the use of peppermint oil because they are averse to this scent. Why Do Spiders Hate Peppermint? The answer to this question remains somewhat unclear. Spiders are sensitive to strong smells in general, not just peppermint, and they do their best to avoid them. They use their legs to smell, and it is thought that they prefer not to crawl through surfaces covered in pungent aromas. While we’re still unsure why spiders hate peppermint exactly, we can look to a couple of studies that affirm this fact. One study in particular revealed that mint strongly repelled spiders. Another showed that essential oils like peppermint oil contains monoterpenoids. Monoterpenoids are natural fumigants against common household pests, such as spiders, which explains their effectiveness in barring them from your home.
