10 Essential Oils That Repel Spiders
Creepy and crawly. You may hate it or fear it for no reason. But, do not kill it unless you are in trouble and it is poisonous. Just repel them from your house. On that note, we are going to list you the best essential oils that repel spiders for real.
But here are some valuable information for you to read.
The landscapes in the earth have drifted many times in geological history. Few species have survived many such catastrophes and are still an integral part of the food chain. Spiders are one such species.
Did you know that modern spiders evolved 250 million years ago? Well, yes. The primitive ones evolved about 400 million years ago.
Spiders are crucial in maintaining a sustainable ecosystem. They are the most abundant predators in the world. They are everywhere except for the highest altitude mountains and polar regions.
Only a few spiders are poisonous whereas others are super beneficial.
For instance, Evarcha culicivora and Paracyrba wanlessi, the two Jumping spider species are called “mosquito terminators.” Spiders play an immense role in pest control.
Moreover, their silk and venom are used in stroke treatment research and bio-silk production.
Many researchers are studying to find some unique and natural ways to repel spiders. While some suggest Ultrasonic repellents, others recommend plant-based repellents.
However, plant-based repellents work the best. And what could be better than essential oils? They are one of the best ways to repel spiders.
But, how does it work?
Essential oils contain natural compounds that have insecticidal properties. These components are none other than monoterpenoids (4). When essential oils are sprayed in the corners, spiders repel because they cannot tolerate their aroma.
An insecticide is a substance that is used to kill insects. It is formulated to repel, kill, mitigate, or harm an insect species. Every insecticide works in a different way. While some disrupt the nervous system of the insects, others repel or damage their entire exoskeletons.
They come in various forms: sprays, gels, baits, and dusts. Chemical-based repellents are dangerous to health. It is best to go with environment-friendly and health-friendly insecticides. Talking of it, essential oils prove the best. (5, 6)
Caution Is Crucial
You cannot just spray or diffuse essential oils to repel spiders. Essential oils are highly concentrated liquids, and it may be not so good for you or your children or pets.
- Never use undiluted essential oils.
- Never congest the room with intense aroma.
It is best to take some precautions before you spray the oil.
- Use gloves and mask.
- Take your pet bed out of the room.
- Spray from a certain distance for safety.
- Open the windows after some time.
- If you are cleaning the garage, carefully note what type of spider it is.
- Do some research on types of spiders, especially in and around your ecosystem.
- Keep the spider spray away from foods and beverages.

10 Essential Oils That Repel Spiders
Though there are many essential oils that repel spiders, the most effective ones are these:
- Peppermint oil
- Tea tree oil
- Lavender oil
- Basil oil
- Cinnamon oil
- Citronella oil
- Cedarwood oil
- Orange oil (sweet)
- Rose oil
1. Peppermint oil
Peppermint essential oil is one of the most effective essential oils to repel spiders. Spiders hate that “minty” aroma. Since the scent of peppermint oil is minty as well as slightly peppery, it can do wonders.
Peppermint oil contains Menthol, menthone, isomenthone, limonene, and b- pinene, which are attributed to its insect repelling property (7).
Add 1 or 2 drops of peppermint oil to 2 tablespoons of vinegar and 50 ml of distilled water. Spray it on the corners of your room to repel spiders.
2. Tea tree oil
Tea tree oil has a strong camphorous aroma with mild spicy notes. The major chemical constituents responsible for it include Terpinen-4-ol, g-Terpinene, a-Terpinene, Terpinolene, 1,8-Cineole, and a-Pinene (8).
Make sure your pet is not accidentally exposed to it while you are spraying. We recommend you to spray it in the corners and the regions you want to clean.
Add 3 to 4 drops of tea tree oil to 100 ml distilled water. Shake well and spray from a distance.
3. Lavender oil
Lavender oil is the most versatile oil. It has an irresistible fresh, soft, and floral aroma. However, the reason it works the best in repelling spiders is due to its compounds Linalyl acetate, Limonene, Lavandulyl acetate, and 1,8-cineole.
They are attributed to insecticidal properties (9). The oil also acts as a room freshener when used in minimal quantity.
Although there are no contradictions found, it is always best to avoid exposure to children, pregnant women, and pets.
You can either diffuse the oil using a nebuliser or spray the oil in higher dilution.
4. Basil oil
Basil essential oil is a colourless liquid with a warm, green, and spicy aroma. The chemical compounds 1,8-cineole, estragole, borneol, geraniol, ocimene, 10-cadinols, and B-caryophyllene are responsible for its insect-repellent property (10).
We recommend spraying the oil in higher dilution than diffusing in the room.
5. Eucalyptus oil
Spiders cannot tolerate the woody, warm aroma of eucalyptus oil. Since eucalyptus essential oil is fortified with monoterpenes like Cineole, a-Terpineol, (þ)-Limonene, Piperitone, a-Pinene, and Caryophyllene, it works effectively in repelling spiders (11).
Spraying eucalyptus oil in higher dilution works well.
6. Cinnamon oil
The chemicals that are attributed to cinnamon’s insect repellent property include Cinnamaldehyde, Cinnamyl acetate, Linalool, b-Caryophyllene, p-Cymene, and 1,8-Cineole (12).
Spiders tend to get out of a space whenever they sense a woody and earthy. That’s exactly what cinnamon’s scent does. Like any other essential oil, even cinnamon oil is potent and requires you to use it correctly.
However, it is best to spray it carefully in higher dilution. Best to avoid exposure to pregnant and breastfeeding women.
7. Citronella oil
Citronella essential oil is great to treat insect bites and deter them as well. It has a fresh, lemony aroma, which irritates the spiders. The compounds Citronellal, Geraniol, Limonene, Camphene, a-Pinene, and Citronellyl acetate are attributed to the its insecticidal property (13).
It is best to use in higher dilution and spray it in around your rooms, especially in the corners. Avoid using the oil during pregnancy.
8. Cedarwood oil
Cedarwood has a woody, sweet aroma and is an excellent insect repellent. The oil has ben used for many years.
The chemical compounds attributed to the insecticidal property include a-Himachalene, a-Cedrene, b-Himachalene, (E)-a-Atlantone, Deodarone, and b-Cedrene (14).
Be careful if you have sensitive skin as accidental exposure may cause irritation.
9. Orange (sweet) oil
Citrus oils are debated for its insect repellent properties. However, there is a lot of anecdotal evidence, proving that they work. Orange oil when sprayed in higher dilution can get spiders out of your place.
Limonene, b-Myrcene, a-Pinene, Geranial, and Neral are the compounds attributed to the deterrent property of orange oil (15).
10. Rose oil
Rose essential oil is known for its sweet floral fragrance. The sweet irresistible aroma is toxic to spiders. The monoterpenes responsible for the insect repellent activity of rose oil include 2-Tridecanone, Geraniol, Farnesol, and Aromadendrene (16).
It can be diffused using a nebuliser for some time to repel spiders as well as freshen the air in the room.
