Citronella for Spiders: A Natural Solution to Keep Your Home Bug-Free

Why Citronella is Effective Against Spiders?

Have you ever walked into a room only to find a spider scurrying across the floor? It's not a pleasant experience, especially if you're not fond of these eight-legged creatures. While spiders are generally harmless, they can still be a nuisance in your home. Fortunately, there are natural remedies available, one of which is citronella.

You may have heard of citronella as an essential oil used for repelling mosquitoes, but did you know it can also keep spiders at bay? In this article, we'll explore how citronella works against spiders and how you can use it to keep your home bug-free.

What is Citronella Oil?

Citronella oil is derived from the leaves and stems of the Cymbopogon plant, which is native to Asia. The oil has a citrusy, lemon-like scent and is commonly used in aromatherapy and as a natural insect repellent. Citronella oil contains compounds such as citronellal and geraniol, which are known to have insecticidal properties.

How Does Citronella Repel Spiders?

Spiders rely on their sense of smell to navigate their surroundings, locate food sources, and find mates. They are also sensitive to certain scents and chemicals, which can either attract or repel them. Citronella oil has a strong smell that many spiders find unpleasant, making it an effective repellent. Additionally, some of the compounds found in citronella oil can disrupt spiders' nervous systems, making it difficult for them to move and function properly.

How to Use Citronella to Repel Spiders?

Now that you know how citronella works against spiders, let's explore the different ways you can use it to repel these pests.

Citronella Candles

Citronella candles are a popular option for keeping mosquitoes away, but they can also work against spiders. Place a few citronella candles around your home, particularly near doors and windows, to create a barrier that spiders are less likely to cross.

Citronella Spray

You can also make your own citronella spray by mixing a few drops of citronella oil with water in a spray bottle. Spritz the mixture around your home, paying special attention to areas where spiders are likely to enter, such as cracks in walls and floors.

Citronella Diffusers

If you prefer a more subtle approach, you can use a diffuser to spread the scent of citronella throughout your home. Add a few drops of citronella oil to a diffuser and let it run for a few hours each day to keep spiders at bay.

Citronella Plants

Another option is to plant citronella in your garden or around your home. The plant has a strong scent that spiders find unpleasant, and it can also help repel other insects like mosquitoes and flies.

Precautions When Using Citronella Oil

While citronella oil is generally safe to use, there are a few precautions you should take to avoid any adverse effects.

Do Not Apply Directly to Skin

Citronella oil can cause skin irritation and should not be applied directly to the skin. If you want to use citronella as a personal insect repellent, look for products that are specifically designed for skin application.

Avoid Ingesting

Citronella oil should not be ingested as it can cause nausea, vomiting, and other digestive issues.

Keep Out of Reach of Children and Pets

Citronella oil should be kept out of reach of children and pets, as it can be toxic if ingested in large quantities.

Citronella vs. Other Spider Repellents

While citronella is an effective natural spider repellent, there are other options available as well. Here's a quick comparison:

Citronella vs. Peppermint Oil

Peppermint oil has a strong scent that spiders find unpleasant, making it an effective repellent. However, it may not be as long-lasting as citronella and needs to be reapplied more frequently.

Citronella vs. Vinegar

Vinegar is another natural spider repellent that works by disrupting their sense of smell. However, vinegar has a strong odor that many people find unpleasant, and it may not be as effective against certain spider species.

Citronella vs. Pesticides

Pesticides are a more aggressive option for getting rid of spiders, but they can also be harmful to humans and pets. Citronella, on the other hand, is a natural and non-toxic solution that is safe to use around your home.


In citronella is a natural and effective way to repel spiders from your home. Whether you choose to use citronella candles, sprays, diffusers, or plants, you can enjoy a bug-free living space without the need for harsh chemicals. Remember to take precautions when using citronella oil and look for other natural repellents if you find that citronella is not effective against certain spider species.
