Spiders are among the most common household pests, and for many people, the sight of a spider scurrying across the floor is enough to cause a shiver down the spine. As a result, people have long sought natural ways to repel these eight-legged intruders, with lavender often touted as a popular remedy. But does lavender really work to keep spiders away, or is it just a myth? In this blog post, we’ll explore the science behind lavender’s reputation as a spider repellent and whether it’s an effective solution for keeping your home spider-free.
1. Why People Believe Lavender Repels Spiders
Lavender has been used for centuries for its pleasant scent and calming properties, but its use as a pest repellent has also been passed down through generations. The idea that lavender can repel spiders is largely based on its strong fragrance, which many believe is overwhelming or unpleasant to these arachnids.
Lavender contains a compound called linalool, which is also found in other essential oils like mint, basil, and coriander. Linalool has been shown to have insecticidal and repellent properties against certain insects, leading to the belief that it might also work on spiders. Because spiders use their sense of smell to detect chemicals in the air, the theory goes that they may avoid areas where strong-smelling lavender is present.
2. What Science Says About Lavender and Spiders
While there is some evidence that essential oils can repel certain insects, the scientific research specifically on lavender and spiders is limited. Unlike insects such as mosquitoes or ants, spiders do not have the same olfactory receptors and rely more on their sense of touch and vibration to navigate their environment. This difference means that while lavender might repel some insects, its effectiveness against spiders is less certain.
- Linalool’s Effects on Insects: Some studies have shown that linalool can be effective in repelling or killing certain insects, but these studies typically focus on pests like mosquitoes, fleas, and moths, rather than spiders. For example, a study published in the Journal of Vector Ecology found that linalool had repellent effects against mosquitoes, but its impact on spiders remains unproven.
- Anecdotal Evidence: Many people claim success using lavender to keep spiders away, citing fewer spider sightings in areas where lavender oil is applied or lavender plants are kept. However, these anecdotes are not backed by rigorous scientific studies, and it’s possible that other factors, such as regular cleaning or the presence of other deterrents, may also play a role.

3. How to Use Lavender to Potentially Repel Spiders
If you’re interested in trying lavender as a spider deterrent, there are several ways to incorporate it into your home. While the results may vary, lavender is a natural and pleasant-smelling option that’s worth exploring.
- Lavender Essential Oil: One of the most common methods is to use lavender essential oil. You can dilute a few drops of lavender oil in water and spray it around windows, doors, and other entry points where spiders might enter your home. You can also apply the oil to cotton balls and place them in corners, closets, and other areas where spiders are likely to hide.
- Lavender Plants: Growing lavender plants in your garden or keeping potted lavender indoors might help deter spiders. The plants release their fragrance naturally, which may create an environment that spiders find less appealing. Plus, lavender plants are relatively easy to care for and can add a touch of beauty to your home.
- Lavender Sachets: Another option is to use lavender sachets. These small pouches filled with dried lavender flowers can be placed in drawers, cupboards, and other enclosed spaces to keep spiders at bay. They’re also a great way to keep your linens and clothes smelling fresh.

4. Other Natural Spider Repellents to Consider
If lavender alone doesn’t seem to do the trick, there are other natural remedies you can try to keep spiders out of your home.
- Peppermint Oil: Like lavender, peppermint oil is another essential oil that’s often recommended for repelling spiders. Its strong scent is believed to be unpleasant for spiders, and many people report success using it around entry points.
- Citrus Peels: Spiders are said to dislike the smell of citrus. Placing fresh citrus peels around your home or using citrus-scented cleaning products can help deter them.
- Vinegar: A mixture of vinegar and water can be sprayed around areas where spiders are likely to enter. The strong smell of vinegar is thought to repel spiders, though it may also be a less pleasant option for you.

5. Practical Tips for Keeping Spiders Out of Your Home
In addition to using lavender and other natural repellents, there are several practical steps you can take to make your home less attractive to spiders.
- Keep Your Home Clean: Regular cleaning can help reduce the number of spiders in your home by removing the webs and eggs they leave behind. Vacuuming regularly, especially in corners and under furniture, can disrupt their habitats and discourage them from sticking around.
- Seal Entry Points: Spiders often enter homes through cracks, gaps, and other small openings. Sealing windows, doors, and any other potential entry points can help prevent spiders from getting inside.
- Reduce Clutter: Spiders love to hide in cluttered areas. Keeping your home organized and minimizing clutter can make it less inviting for spiders to settle in.
- Use Screens: Installing screens on windows and doors can help keep spiders and other pests out, especially during warmer months when you’re likely to have windows open.
