Updated April 17, 2017

If you live near water, there's a constant threat of mosquitoes. Since mosquitoes in the larvae stage inhabit the water, feeding off algae and other bacteria, you may be bitten numerous times without even realising it if you are not protected. This can sometimes lead to a more serious condition. Using a few ingredients will kill the mosquito larvae and protect you from bites.

Thai Lemongrass

Thai lemon grass is a natural insecticide that kills mosquito larvae and is most effective in plant form. Purchase it at any organic market or grown your own. If you will be spending time in the water, this is a natural way to protect yourself and kill any larvae that may swim to the surface to feed on you.

Simply take a fresh stalk of lemon grass by grasping it near the ground and pulling it sideways. This will break off the clumpy part. Peel any surrounding leaves and break off the blades behind the stem of the base. Then, using your fingers, bend the stem and rub generously, so that the juicy mass is excreted into your palm. Apply the mixture to your entire body and you are ready to enter the water. This application usually last for four to five hours. If you will be spending more time in the water, apply the mixture again.

Herbal Insect Repellent

Here is another environment-friendly recipe to kill mosquito larvae while you are in the water. Use 2 1/2 tsp of two of the following essential oils: cedarwood, rose geranium, citronella, pine or juniper. Purchase them at any health store. You will also need 1 cup of 190-proof grain alcohol. Combine these ingredients in a jar. Tightly seal it and shake well. This mixture can also be stored in smaller bottles for later. Apply the mixture to any exposed parts of the skin, but do a patch test first to ensure that you skin will not react adversely. Also dab some of the mixture on clothing.


Mosquito larvae are also drawn to standing water, particularly during the rainy season. If you have a backyard fountain, this recipe will kill them. Place two garlic bulbs and two hot peppers in a blender with 1/2 cup of water. Blend the ingredients and strain. Add enough water to the concentrate to make 1 gallon of the garlic pesticide. For additional strength, add 2 tbsp of vegetable oil. Pour the mixture in a spray bottle and coat the surface of the fountain.
