Lavender: A Natural Spider Repellent

Many of us are familiar with the soothing aroma of lavender. We use it in our baths, diffusers, and even in our cooking. But did you know that this fragrant herb also has a reputation for repelling spiders?

Does Lavender Kill Spiders?

Contrary to popular belief, lavender does not kill spiders. Instead, it acts as a natural deterrent, repelling spiders with its potent aroma. Lavender contains a compound known as linalool, which is found in many insect repellents. This compound, coupled with lavender’s strong scent, makes it an unappealing environment for spiders.

How Does Lavender Affect Spiders?

Although there is limited scientific research specifically on lavender’s effect on spiders, some studies suggest that lavender essential oil may have repellent properties against certain arachnids and insects. These studies indicate that the strong scent of lavender is unappealing to spiders, encouraging them to leave the area.

Keep in mind that while lavender can be effective, its strength as a spider deterrent may vary depending on the type of spider and the specific conditions in your home. If you have a severe spider problem, it’s best to consult a pest control professional.

Using Lavender to Deter Spiders

There are several ways to use lavender as a spider deterrent. One common method is to create a lavender essential oil spray. Mix 10 drops of lavender essential oil with 16 ounces of water in a spray bottle, and spray it in areas where you’ve noticed spider activity. You can also place potted lavender plants near doors and windows, or use lavender-scented candles or incense sticks to deter spiders.

Remember, lavender does not kill spiders; it merely repels them. By using lavender in various forms, you can create a natural and non-toxic spider deterrent that is safe for both you and the environment.

Risks and Downsides

While using lavender as a spider deterrent is generally safe, there are a few potential risks and downsides to be aware of. Some people may be allergic to lavender, and using the essential oil in large amounts in enclosed areas can be dangerous. Moreover, lavender may also repel beneficial insects, so be mindful of this when using it outdoors.

Natural Alternatives to Control Spiders

If you’re looking for other natural ways to control spiders in your home, consider using lemon-scented cleaners, citronella candles, or peppermint essential oil. Even a mixture of white vinegar and water can be effective. Remember to spray these natural repellents around doors, windows, and room corners to effectively deter spiders from entering your home.


While lavender may not kill spiders, it can certainly help keep them at bay. Its strong scent deters spiders, creating a less appealing environment for them. This fragrant herb can be used in various forms, making it a versatile and natural alternative to commercial spider repellents. However, if you have a severe spider infestation, it’s best to seek advice from a pest control professional.

Frequently Asked Questions

Can I use lavender oil directly without diluting it?

No, it’s not recommended to use lavender essential oil directly without diluting it. Essential oils are very concentrated and can cause skin irritation or reactions if used undiluted. Always dilute essential oils with a carrier oil or water before use.

How often should I use lavender to deter spiders?

The frequency of using lavender as a spider deterrent can vary. However, generally, you should reapply lavender spray or replace lavender plants, candles, or incense sticks once their scent fades. This could mean reapplying or replacing every few days to a week.

Can lavender harm my pets?

Lavender is generally considered safe for most pets. However, some animals may have a sensitivity or allergic reaction to lavender. If you have pets, it’s best to consult with your veterinarian before introducing lavender or any other essential oils into your home.

Can I use dried lavender instead of lavender oil?

Yes, dried lavender can also be used to deter spiders. You can place sachets of dried lavender near doors, windows, or other areas where you’ve noticed spider activity. However, keep in mind that the scent of dried lavender may not be as potent or long-lasting as lavender essential oil.

Does lavender repel other pests besides spiders?

Yes, lavender is known to repel a variety of pests, including moths, flies, and mosquitoes. However, its effectiveness can vary depending on the type of pest and the specific conditions.
