Mosquitoes are more than a nuisance—they can spread diseases like West Nile, dengue, Zika, and yellow fever. If you’re searching for a natural mosquito repellent, you might wonder if essential oils can keep mosquitoes away.
Let’s break it down, including how to use essential oils and their effectiveness compared to synthetic insect repellents like DEET.
Key Takeaways
- Mosquitoes are attracted to humans by scent, carbon dioxide, and heat, which essential oils can disrupt.
- Essential oils like citronella, peppermint, and neem repel mosquitoes naturally but require frequent application to remain effective.
- Safe use of essential oils includes diluting them, creating sprays, or using diffusers to spread their scent.
- Essential oils offer natural short-term solutions, but synthetic repellents or professional pest control provide more lasting protection.
How Essential Oils Work as Mosquito Repellents
Species of mosquitoes, like Aedes aegypti and Culex, are drawn to humans by carbon dioxide, body heat, and even the way we smell.
To counter this, essential oils are plant-based, natural products that can help repel these pests by interfering with their sense of smell. Some oils like neem and cinnamon oil can even kill larvae when used in standing water.
With their different active ingredients, these aromatherapy oils work well for short-term use.
Nowadays, they are a popular option for those looking for alternatives to synthetic products.

How to Use Essential Oils for Mosquito Control
Using essential oils to avoid mosquito bites is easy and versatile. Whether you’re making a spray or applying them to your skin, here are four ways to use them safely:
Dilute with a Carrier Oil
Essential oils are powerful, but applying them directly can cause skin irritation. That’s why diluting them with a carrier oil, like coconut or almond oil, is essential.
Carrier oils help spread the essential oil evenly across your skin while minimizing the chance of a reaction. Coconut oil is particularly effective because it also acts as a natural moisturizer, which can help the oils last longer on your skin.
Aim for a safe ratio of 10–15 drops of essential oil per tablespoon of carrier oil.
DIY Bug Spray
A homemade bug spray is an easy and effective way to use essential oils for mosquito control.
Start by mixing 10–15 drops each of oils like citronella, lemongrass, and thyme oil with half a cup of water or witch hazel.
One common formulation includes witch hazel to help the oils blend better and feel refreshing when sprayed on your skin.
Shake the bottle well before each use, and spray it on your skin, clothes, or outdoor areas to keep mosquitoes away. Reapply every couple of hours for the best results.
Lotion Application
Mixing essential oils with unscented lotion is a convenient way to keep mosquitoes off your skin while staying moisturized.
Add 10–20 drops of oils like citronella or lavender to 2 ounces of lotion. This allows the lotion to carry the oils across your skin evenly, making it easier to apply and ensuring they don’t evaporate too quickly.
It’s a great option for people with sensitive skin since the lotion helps prevent irritation.
Use a Diffuser
If you’re looking to repel mosquitoes in a specific area, a diffuser can do the trick.
Add 5–10 drops of oils like citronella, lemongrass, or cedarwood to your diffuser with water. When turned on, the diffuser disperses the oil into the air, masking the scents mosquitoes use to find you.
This method is perfect for patios, living rooms, or bedrooms, especially during those peak mosquito hours at dusk and dawn.
How Essential Oils Compare to DEET
DEET and picaridin are two of the most effective synthetic insect repellents approved by the Environmental Protection Agency (EPA). They offer long-lasting protection against mosquitoes, making them great choices for areas with heavy mosquito activity.
If you’re looking for a plant-based option with repellent activity, the Centers for Disease Control and Prevention (CDC) recommends oil of lemon eucalyptus (OLE) or its active ingredient, PMD.
These natural repellents can keep mosquitoes, including Anopheles mosquitoes that spread malaria, at bay, though they may not last as long as DEET.
They are a good choice if you want to avoid synthetic options, but they typically require frequent reapplication to remain effective.
Are Essential Oils Enough?
While essential oils are a great plant-based option, they may not provide the same level of protection as synthetic bug sprays. DEET, picaridin, and PMD are better for areas with high mosquito activity or a higher risk of diseases.

Frequently Asked Questions
Can essential oils be harmful to pets if used for mosquito control?
Yes, essential oils can harm pets if used improperly. Oils like tea tree and clove can be toxic to cats and dogs if ingested or inhaled in high concentrations. Always dilute oils and use them in pet-safe ways, such as applying in well-ventilated areas or avoiding direct contact with your animals.
How long do essential oils remain effective after application?
Essential oils typically last 1–3 hours after application, depending on the oil and conditions. Florida’s humidity can reduce effectiveness, so frequent reapplication is necessary for continued protection against mosquitoes.
Can essential oils prevent mosquito breeding in standing water?
Some oils, like neem or cinnamon, can kill mosquito larvae in small amounts of water, but they’re not practical for large areas. Professional mosquito treatments are more effective for long-term breeding control.
