Then, pour your solution into a spray bottle, so that you can use it easily. Take note that concentrated lemongrass oil can cause skin irritation, so you need to dilute it first. Test it on a small patch of your skin before you apply it to the rest of your body.

Lemongrass products such as large torches, lanterns, and tea lights can add more relaxation to your yard. Forming a perimeter around your barbecue or picnic area with torches, lamps, and candles, protects a significant amount of yard space from mosquito activity.

You can mix lemongrass oil with lemon eucalyptus oil for mosquito protection of about five to six hours per application. You can also mix lemongrass oil with rosemary oil for a more fragrant formula. This can ward off a greater number of insect species.

  5. Add lemongrass to your garden. If you do this, you start to have your own personal supply of lemongrass oil. All you need to do is grind up the leaves, rubbing the leaf and stalk juices on your skin, or by chopping the stalks and leaves.
