Co-authored by Jessica Gibson

Last Updated: February 9, 2020 References Tested

Lemongrass essential oil is a popular scent for homemade sprays. Its grassy, citrusy flavor combines well with other essential oils, making it effective for insect repellent or room spray. Shake the lemongrass essential oil with other insect-repelling oils before going out in mosquito-infested areas. You can also make a room spray with refreshing lemongrass, spearmint, grapefruit, and rosemary essential oils. Spritz it in the air on or linen to neutralize odors.

Making Insect Repellant with Lemongrass

1
Pour neem oil, vodka, and distilled water into a bottle. Set a small funnel on a 3 fl oz (89 ml) spray bottle and pour in 1 teaspoon (4.9 ml) of neem oil. Add 1 tablespoon (15 ml) of vodka or denatured alcohol and 4 tablespoons (59 ml) of distilled water.^{[1]

- It's important to use distilled water instead of tap water to prevent the spray from spoiling.
- If you don't like the strong scent of neem oil, you can leave it out. However, if you're specifically trying to repel mosquitos, consider adding it.

Add lemongrass, lavender, tea tree, citronella, and geranium essential oils. Citronella and tea tree essential oils may have strong scents, but they're great at keeping insects away. Pair them with lemongrass, lavender, and geranium essential oils, which smell wonderful and can repel flies, mosquitos, and fleas. Put these oils into your bottle:^{[2]

Screw the lid on the bottle and shake the spray for 10 seconds. Put the lid on the bottle and screw it on tightly so the bottle is completely sealed. Shake the spray for at least 10 seconds to help the oils combine with the vodka and water.^{[3]

- Spray the repellent before each use since the oils will separate as the spray is stored.
4
Spray the lemongrass mixture on your skin before going outside. If you know you'll be going outside in insect or mosquito-infested areas, spritz your skin thoroughly. You might need to reapply the repellent if you'll be outside all day.^{[4]

- Store the repellent at room temperature for up to 3 years. Although you could keep using the spray, the oils will become less effective the longer they're stored.
Tip: Keep this lemongrass insect repellent out of children's reach. If they ingest the spray, call poison control immediately.

Mixing Lemongrass Room or Linen Spray

- If you don't have witch hazel, use vodka. Either of these help release the essential oils when you use the spray.
2
Add lemongrass, spearmint, grapefruit, and rosemary essential oils. Put all of your essential oils into the small bottle. If you'd like to make an all-lemongrass spray, use only 30 drops of lemongrass essential oil. For a refreshing lemongrass room spray, add all of these to your bottle:^{[6]

- 10 drops of spearmint essential oil
- 10 drops of grapefruit essential oil
- 5 drops of rosemary essential oil

Close the bottle and shake the mixture for 10 seconds. Put the screw cap tightly on the bottle so the bottle is completely sealed. Then, shake the bottle to combine the witch hazel, water, and essential oils.^{[7]

- Shake the bottle before each use since the oils and water will separate a little.
4
Spritz the lemongrass spray around your home or on linen. To remove unpleasant smells or to just make your room smell better, spray the mixture around the room. Keep spraying until you can smell the lemongrass. If you're ironing linen, spray the surface of the fabric with the mixture until it's wet. Then, iron the linen to remove wrinkles.^{[8]

- You can also spray your pillow or sheets before bed to enjoy a calming scent as you fall asleep.
5
Use the lemongrass spray within 3 years. Store the spray at room temperature and shake it gently before using it. Since the essential oils will become rancid over time, discard the spray after 3 years or if it develops an unpleasant odor.^{[9]

Tip: Remember to label the outside of the bottle so you know what type of spray you made. Include the date so you know how long to store the spray.

Warnings

Avoid using essential oil products around young children, because their skin and respiratory systems are more sensitive to them.^{[10]
