How to Make Lemongrass Insect Repellent: A Natural Solution
Making lemongrass insect repellent is surprisingly simple and offers a natural, effective alternative to chemical-laden products. The process involves extracting the repellent properties of lemongrass, either through oil infusion or direct application, to create a safe and fragrant solution.
The Allure of Lemongrass: A Natural Bug Deterrent
For centuries, lemongrass has been valued not only for its culinary and aromatic properties, but also for its natural insect-repelling capabilities. Originating in tropical regions of Asia, this versatile grass boasts a high concentration of citronellal and geraniol, compounds known to effectively deter mosquitoes, flies, and other bothersome insects. Unlike synthetic repellents that can contain harsh chemicals like DEET, lemongrass offers a gentler, more environmentally friendly approach to pest control. Its pleasant citrusy scent also makes it a more appealing option for many users.

- Natural and Safe: Avoids harmful chemicals and potential skin irritations.
- Customizable: Tailor the strength and scent to your preference.

Methods for Creating Lemongrass Insect Repellent
There are several ways to create lemongrass insect repellent at home, each with its own advantages and level of effort:
- Lemongrass Infused Oil: This method involves steeping lemongrass in a carrier oil to extract its repellent properties.
- Lemongrass Spray: A simple solution using distilled water and lemongrass essential oil.
- Direct Application (with Caution): Crushing and rubbing fresh lemongrass leaves on the skin.
Detailed Steps: Lemongrass Infused Oil
This method is ideal for creating a potent and long-lasting repellent.
Ingredients:
- 1 cup carrier oil (e.g., coconut oil, almond oil, olive oil)
- 1 cup chopped fresh lemongrass (or ½ cup dried lemongrass)
- Optional: Other essential oils (e.g., eucalyptus, lavender)
Instructions:
- Prepare the Lemongrass: Chop fresh lemongrass into small pieces. If using dried lemongrass, crush it slightly to release its aroma.
- Combine Ingredients: Place the lemongrass and carrier oil in a clean glass jar.
- Infuse the Oil (Slow Method): Seal the jar tightly and place it in a sunny location for 4-6 weeks, shaking it occasionally.
- Infuse the Oil (Faster Method): Alternatively, gently heat the mixture in a double boiler or slow cooker on low heat for 2-3 hours. Monitor closely to prevent burning.
- Strain the Oil: Strain the infused oil through a cheesecloth or fine-mesh sieve into a clean jar. Discard the lemongrass solids.
- Optional: Add Essential Oils: For added potency and fragrance, add a few drops of other insect-repelling essential oils like eucalyptus, lavender, or peppermint.
- Store Properly: Store the infused oil in a cool, dark place in an airtight container.
Detailed Steps: Lemongrass Spray
This method is quick and easy, perfect for on-the-go application.
Ingredients:
- 2 cups distilled water
- 20-30 drops lemongrass essential oil
- Optional: A few drops of other essential oils (e.g., citronella, tea tree)
- Spray bottle
Instructions:
- Combine Ingredients: Pour the distilled water into the spray bottle.
- Add Essential Oils: Add the lemongrass essential oil (and any other optional oils) to the water.
- Shake Well: Secure the spray bottle cap and shake vigorously to ensure the oils are thoroughly dispersed.
- Shake Before Each Use: Since oil and water naturally separate, shake well before each application.
- Spray Application: Spray the mixture on your skin, clothing, and surrounding areas to repel insects. Avoid spraying directly into your eyes or on open wounds.
Detailed Steps: Direct Application (Use Caution)
This method is the most direct but requires careful consideration.
Instructions:
- Choose the Right Lemongrass: Select a stalk of fresh lemongrass.
- Prepare the Leaf: Gently bruise or crush a small portion of the lemongrass leaf to release its oils.
- Test a Small Area: Rub the bruised leaf on a small area of your skin (like your forearm) and wait to see if there’s any reaction. Important: Discontinue use if irritation occurs.
- Apply Cautiously: If no irritation occurs, gently rub the crushed leaf onto other exposed areas of your skin, avoiding your eyes and mouth. Reapply as needed.
- Wash Hands Thoroughly: After applying, wash your hands thoroughly to avoid getting the oil in your eyes.

- Failing to Test for Allergic Reactions: Always perform a patch test on a small area of skin before applying any homemade repellent liberally.
- Storing Repellent Incorrectly: This can reduce its effectiveness and shelf life. Store in a cool, dark place in an airtight container.
- Expecting 100% Protection: Natural repellents may not be as effective as DEET-based products and may require more frequent application.
Safety Precautions
- Allergy Testing: Always perform a patch test before widespread use.
- Eye Contact: Avoid contact with eyes. If contact occurs, rinse thoroughly with water.
- Pregnancy and Breastfeeding: Consult with a healthcare professional before using essential oils if you are pregnant or breastfeeding.
- Children: Use with caution on children. Always dilute essential oils appropriately and avoid direct application to young children.
- Sun Sensitivity: Some essential oils can increase sun sensitivity. Avoid prolonged sun exposure after applying the repellent.
Frequently Asked Questions (FAQs)
What type of lemongrass should I use?

Can I use lemongrass essential oil instead of fresh lemongrass?
Yes, you can use lemongrass essential oil. It’s a more concentrated form of the plant’s repellent compounds. When using essential oil, always dilute it appropriately with a carrier oil or water before applying it to the skin.
How often should I reapply the lemongrass insect repellent?
The frequency of reapplication depends on factors like humidity, sweating, and the intensity of insect activity. Generally, it’s recommended to reapply every 2-3 hours or more frequently if needed.
Does lemongrass insect repellent work against all types of insects?
Lemongrass is most effective against mosquitoes, flies, and gnats. It may also deter other insects like fleas and ticks to some extent, but its effectiveness against these pests may vary.
How long does homemade lemongrass insect repellent last?
The shelf life of homemade lemongrass insect repellent depends on the storage conditions and the method used. Infused oils can last for up to a year when stored in a cool, dark place. Sprays may last for several months.
Can I use lemongrass insect repellent on my pets?
While lemongrass is generally safe for pets, it’s best to consult with your veterinarian before using it on them. Some essential oils can be toxic to animals, so it’s important to ensure that the repellent is properly diluted and used in moderation.
What are some other essential oils that can be combined with lemongrass for added effectiveness?
Several other essential oils have insect-repelling properties and can be combined with lemongrass, including citronella, eucalyptus, lavender, peppermint, and tea tree oil.
Is lemongrass insect repellent safe for babies and young children?
Use extreme caution when using lemongrass insect repellent on babies and young children. Essential oils should be heavily diluted, and direct application to the skin should be avoided. Consult with a pediatrician before using any homemade repellent on infants.
Can I grow my own lemongrass?
Yes, lemongrass is relatively easy to grow in warm climates. You can purchase lemongrass plants from garden centers or start them from seeds. Growing your own lemongrass ensures a fresh and readily available supply for making repellent.
Where can I find lemongrass essential oil?

Ensure you’re using fresh, high-quality lemongrass or essential oil. Increase the concentration of lemongrass in your recipe. Combine lemongrass with other insect-repelling essential oils. Reapply the repellent more frequently. Consider making lemongrass-infused oil, which tends to be more potent than a water-based spray.
